Streamlined Inspections & Summary Reports

2/5/2025

0 Comments

 
I’ve been involved in the chimney industry since the late ‘70s when my wife and I started our chimney sweeping business. Anyone who was a sweep during this time enjoyed a business that boomed during the fall and winter, then fell off in the spring and summer. How times have changed. In these early days, there were no criteria for chimney inspections. Chimney sweeps swept the chimney, maybe noted some issues to the homeowner about the soot level,and left. Litigation and insurance companies started to change the industry and were the basis for developing the industry’s Standard of Care. 
Taking the NFPA 211 Annex and placing it into installation type.
One day, at the turn of the century, as I sat on my deck relaxing, my mind wandered back to the year 1998 when a bunch of guys and I drafted the Levels of Inspections, Degrees of Access, and the list of inspection items in Chapters 14 & 15 and in the NFPA 211 Annex. As I thought about how it would be incorporated into a chimney technician’s inspection, I realized it would be difficult for the technician to try to hit all the inspection items from memory. Additionally, some items would apply to one type of installation, but not all. Today, 25 years later, some chimney technicians are still missing inspection items from NFPA 211. It’s almost as if our industry Standard of Care slipped through our fingers. Is it because there are too many items for a technician to inspect? No, we've become lazy and pick and choose what we want. This led me to begin my 10,000 hours of creating what became the Flue and Hearth Notes™ inspection forms. 
Different Installation Types.
Forty years ago, before NFPA 211’s Inspection criteria, an inspection form was created with a fireplace and a handful of inspection items to check. It was in triplicate form, and chimney sweeps used it for all types of installations. It was used for all chimneys. However, a fireplace inspection differs dramatically from a chimney serving a gas water heater and an oil boiler venting into one flue. Unfortunately, some chimney sweeps and technicians still use these forms.  Twenty years ago, I envisioned building a comprehensive inspection form Based on NFPA 211 but for specific applications such as a Masonry Fireplace, a Prefabricated Fireplace, a Masonry Thimble Chimney Serving an Appliance(s), and a Prefabricated Chimney Serving an Appliance(s).  Although these installations all have chimneys, each chimney vents a different type of heating unit or fireplace. In addition, the fuels can differ: LP gas, natural gas, oil, coal, wood, and pellets.
No installations are the same, but you will see the same types of defects.
Every installation is unique, but the types of defects are the same across the board. For instance, defects can range from vertical and horizontal cracks, protruding mortar joints, stacked liners, and misaligned liners to missing chimney liners.
Start creating a Unity track: Defining what’s important.
One of my all-time favorite stories is one Tom Grandy shared about a trip to the dentist. As with any dental visit, almost everyone gets the lecture about how to floss twice a day, and we are given the same demonstration of how to floss each time we brush. One day, after a lecture on flossing, Tom shared what we all feel, and the dentists regularly hear. “I hate to floss!” I suppose that day, the dentist had heard it for the umpteenth time, and he was ready. He responded, “OK, just do the teeth you want to keep!” This has similarities to our industry. A technician can’t just pick and choose what they want to search for (the insurable cracked flue liner). All inspection items must be investigated (NFPA 211, Chapters 14, 15, and the Annex). I felt pulling all this together would create unity on chimney inspections in our industry since it didn’t seem to be happening.
The start of the Flue and Hearth Notes™ (10,000 hours) of form building and why and how they are built.
I began with the vision of a unified form. I grouped inspection items with installation types. I further included an area for defects related to specific areas, such as a chimney liner. I grouped inspection items per area where they were found in the chimney or fireplace. I included information on appliances. I had professionally created drawings and pulled everything into multiple inspection report forms. Recently, I added more forms to the offering and broke them down by fuels. We now have eight form types: Masonry Fireplace, Masonry Fireplace with a Hearth Stove, Masonry Fireplace with an Insert, Masonry Thimble Chimney Serving a Solid Fuel Appliance, Masonry Thimble Chimney Serving a Liquid Fuel Appliance(s), Prefabricated Chimney Serving a Solid Fuel Appliance, Prefabricated Chimney Serving a Liquid Fuel(s) Appliance, and Prefabricated Fireplace and Chimney. We have Level I and Level II forms for each installation type. That’s 16 forms in total. But then, we went a step further.

Tom and Esther Urban prepare to sweep chimneys in 1980. They saw the need to manufacture a chimney camera and started making them over 40 years ago.
A man is leaning over the steering wheel, looking scared and exhausted.
Trying to remember all of the inspection items in NFPA 211 Chapters 14 & 15, and the Annex can be tough even for seasoned veterans.
This form has a fireplace drawing and a handful of inspection items.
This outdated inspection form was created in the 1980s. It has been outdated for several years. It does not cover all of the inspection items in the NFPA 211 Standard, Chapters 14 & 15, and the Annex. Also, it is not a "catch all" form. It specifically targets a fireplace.
The inspection form lists multiple inspection items by transition of the fireplace. It includes a fireplace drawing. It is a Level I form.
The Flue & Hearth Notes™ Inspection forms is a Do-Confirm checklist with questions based on NFPA 211, Chapters 14 & 15 and the Annex. This is the form for a Level 1 inspection. A Level 2 form is also available. There are eight form types as listed in the image below. Click the image for more information.

There are 8 installation types available for these forms: Masonry Fireplace & Chimney, Masonry Fireplace & Chimney Serving a Hearth Stove, Masonry Fireplace & Chimney Serving an Insert, Masonry Thimble Chimney Serving a Solid Fuel Appliance, Masonry Thimble Chimney Serving a Liquid Fuel(s) Appliance(s), Prefabricated Fireplace & Chimney, Prefabricated Chimney Serving a Solid Fuel Appliance, Prefabricated Chimney Serving a Liquid Fuel(s) Appliance(s). For each type there is Level 1 and Level 2 forms.
​Summary Forms
We brainstormed one day and came up with the need for a new type of form. We call this form a Summary Form. These forms are available in the same installation types listed above. These forms are unique because we further break the installation into sections, as featured below. Within these sections is a color-coded area key to check whether it’s in Operational Ready Condition, Operational Deficient Condition, or Hazardous Condition. Documenting your findings this way makes sense. For instance, the flue liners “C” may be damaged. Based on this finding, condemning the whole chimney and telling the customer it is hazardous is incorrect. Maybe areas D-H are in Operational-Ready Condition. Maybe areas A & B are in Operational Deficient Condition – meaning the crown is cracked, needs some repairs, and the chimney from the roof up (B) needs tuckpointing. It’s great to get good news with the not-so-good news.
There are 8 fireplace drawings with different transition areas highlighted.
There are 8 installation types of Summary Forms. These forms break down the installation by transitions. They are designed as an easy-to-understand form for the customers. Included is Conditions featuring: Operational Ready, Operational Deficient, and Hazardous Conditions. There are two pages for drawings that correspond to the notes page with letters. For more information, please click the image above.
PictureOur Summary Forms are designed for your customer. It breaks out the conditions of each section, where you can check off the condition to the left of the description.
Another beautiful part of this form is the explanations included for the three conditions. If used correctly, these forms will convey to the homeowner the findings of your inspection in an easy-to-understand format. In addition to explaining the conditions, they include a cover page where your information and receipt can be placed. 
​Start when business is good, so you are ready when the slow times start!
Suppose you put the principles of inspection unity into practice now. When the slow times come, your business will thrive with forward-scheduling items like tuckpointing (Operational Deficient) that can wait for repairs. Your team will perform their inspections using the NFPA 211 Inspection Items, and they will all be on the same page. Your technicians will evaluate the entire chimney per the forms (and Industry Standard of Care), finding defects and verifying conditions. They can communicate the areas of their chimney that are in Operational-Ready Condition. Some may need fixing but not immediately (Operational-Deficient), and some may need repair before further use (Hazardous Condition). 
You stop trying to sell the job when the job can sell itself without using scare tactics of condemning an entire chimney. If you can continue to do what you’re doing, you will quickly put yourselves and the industry out of business. 
Standardizing inspection requirements across the board puts everyone on a level playing field. Everyone should already be checking everything outlined in NFPA 211. Some companies do and are very diligent about it. Unity and standardization are the keys to moving your business and this industry forward. Thanks for listening. Tom

What Our Industry Is Missing

2/3/2025

0 Comments

 
​I recently read that people spend much of their spare time on smartphones and the internet. Hey, with so much information and entertainment, why pick up a book or learn a new hobby when you can watch someone else in an app? The desire to discover, learn more, understand, and be the best is diminishing. Instead of scanning the entire flue, searching every crack and joint, the inspection often stops at the vertical crack in the flue tile. It’s like a “good enough” mentality. When it comes to chimneys, if defects are missed, is this ever “good enough”? It seems that we, as an industry, are failing the American Public.
Insufficient or poor-quality information
I’ve been sent reports from homeowners all over the US. They are concerned, and from these reports I’ve seen, they have a right to be. Some of these reports have been from industry “leaders.”
In these reports, confusion is woven into many of the inspection reports I’ve received. Some contain a multitude of pages (up to 20+). Some have paragraphs on some pages, and several pages later, the corresponding image sits surrounded by other images. Connecting the paragraphs with the photos is impossible in the homeowner's eyes. In addition, I’ve picked up on some defects from the pictures not mentioned in the report and incorrect information in the report.
Some sweeps still use the old single fireplace with checkboxes from almost four decades ago. The customer wonders what a fireplace form has to do with their oil boiler and gas water heater. Then there’s NFPA 211 Chapters 14 and 15, along with the inspection items, which aren’t listed on these old forms. 
 Some reports contain technical jargon and scary words like condemned, house fire, death, etc. The customers don’t understand what’s going on. They feel pushed and aren’t sure where to turn to get their questions answered. Sometimes, a competitor straightens them out. Other times, they find us online and send us copies of their reports. This is a credibility wrecker within this industry. 
Customers won’t buy something they don’t understand.
Customers who don’t understand why they need a repair may get a second opinion because the report is weighted in technical jargon and scare tactics. It’s essential that the customer understands the defect first and then is presented with a solution written in an easy-to-understand manner. That’s called solution selling. Present the defect so the customer understands the problem. THEN, present the solution, which usually sells itself. Customers feel better because they “get it,” they are making an informed decision, and aren’t pressured by threats such as “Your house will burn down.”
No unity of inspections
In 1998, a group of chimney specialists created Chapters 14 and 15, including the Levels of Inspection and the inspection items in the NFPA 211 Annex. The goal was to eliminate confusion about chimney inspections and streamline the industry. This created the chimney industry Standard of Care. Unfortunately, not all chimney inspection technicians use this information, even today, 25+ years later. 
Imagine if each airline pilot's prep before a flight with 250 people wasn’t standardized with an industry-standard preflight checklist. Some might take shortcuts. Others will take a long time to check everything. But no one would be on the same page. This lack of coordination historically resulted in accidents. When there is no consistency, problems arise. This is happening in our industry.
The future of our industry depends on unity, particularly chimney inspections. This was the goal in 1998, which was the thorn in everyone’s side).
If our industry continues to ignore the Levels of Inspection and not follow the requirements set forth in NFPA 211 Chapters 14 & 15 and items in the Annex, it will not end well. Usually, this happens with litigation. It is already happening. It’s called failure to report. That’s also in NFPA 211. NFPA 211 Chapters 14 & 15 are now case law. The precedence is set. If you are not following the Inspection of Existing Chimneys (chapter 14) and hitting these items, it’s just a matter of time. It may lead homeowners to get rid of their fireplaces.
An old, outdated chimney inspection form that does not follow the NFPA 211 Guidelines.
This is an outdated inspection form used by some sweeps to cover a variety of installation types. It is MISSING inspection items set forth in NFPA 211, Chapters 14 & 15 and the Annex which is the Chimney Inspection Industry's Standard of Care.
There are 8 forms with a variety of chimney type.
Here is an example of modern inspection forms by installation type. Each form has a multitude of applicable checkboxes for that type of installation. There are eight installation type forms available. These are the Flue & Hearth Notes™ Inspection Forms. Click on the image for more information.

Customers become confused when they read a report with technical terms. It's important to understand the defect first, then to be presented with a solution, preferably options.
A blue book with this copy on the front: NFPA 211 Standard for Chimneys, Fireplaces, Vents, and Solid Fuel-Burning Appliances, 2024.
The National Fire Protection Association (NFPA) publishes the 211 Standard. This is the Standard for Chimneys, Fireplaces, Vents, and Solid Fuel-Burning Appliances. Within this book in chapters 14 & 14, and items in the Annex, is the chimney sweeping industry Standard of Care. It is case law.
​Individuals other than sweeps can do chimney inspections.
Other trades are already doing chimney inspections, and Home Inspectors do chimney inspections as part of an entire home inspection. More and more people are learning about NFPA 211 and the inspection items. Most are interested in performing the best inspection possible, and many are already following NFPA 211.
Each member of a company or team should retrieve the correct and consistent information.
How often are there inconsistencies within your organization? Are all of your technicians catching everything? Or are they stopping at the first crack or sign of a chimney fire, writing an estimate, and leaving without a full inspection?
As an industry, we must step up to the plate. We must perform a full inspection, checking everything, including the little things. We need to explore, discover, and follow all of the inspection criteria set forth in NFPA 211, Chapters 14, 15, and the Annex. After all, every chimney is a little different, although the defects are usually the same. If you are not using NFPA 211 as your guideline for inspections, then please take it out of your proposals & estimates. This way, if something goes bad, at least you didn’t incriminate yourself.
Four pages contain a report sectioned into 8 drawings of fireplace transition points. Pictures of the damage are shown on other pages.
The Flue & Hearth Notes™ Summary Forms give you the opportunity to create an easy-to-understand inspection report for your customers. You can add images that correspond with the areas of the installation. There are also definitions for three conditions: Operational Ready, Operational Deficient, and Hazardous. Each section has a "traffic light" so you can mark that section appropriately. These forms are available for 8 inspection types" Masonry Fireplace & Chimney, Masonry Fireplace with an Insert, Masonry Fireplace with a Hearth Stove, Masonry Thimble Chimney Venting a Solid Fuel Appliance, Masonry Thimble Chimney Chimney Venting a Liquid Fuel(s) Appliance(s), Prefabricated Fireplace & Chimney, Prefabricated Chimney Venting a Solid Fuel Appliance and Prefabricated Chimney Venting a Liquid Fuel(s) Appliance(s).

The importance of chimney scanning for building code authorities, home inspectors, and insurance adjusters

1/21/2025

0 Comments

 

​Whether performing chimney inspections or reading a chimney inspection report, one thing is clear: It is hard to argue with a high-resolution picture taken during a chimney inspection with a camera showing defects deep inside the flue. A chimney inspection done with the naked eye is no comparison to an internal chimney scanning. I used a 5’ chimney prop with hidden defects in the chimney inspections and classes I taught for 21 years. Almost 99.9% of the time, the inspectors missed an opening defect within the flue by inspecting only with a flashlight and the naked eye. These defects were only 17” from their face. 

Images and videos from scanning chimneys are one part of the equation. If you read a report with multiple pictures, can you understand what the defects are and what caused them? Here are some other questions to consider:

1. Can you identify and define “What is a defect?” within the chimney interior?"
2. Can you determine how the defect was created or the most probable way it was created?
3. Did you rule out other causes and conditions, leaving probable causes as to why the defect is there?

In my forty years in the chimney industry, I have accumulated a lot of images, videos, and knowledge regarding chimney construction and defects. I have also spoken at national and state organizations and taught at a national trade organization school for over twenty years (Chimney Safety Institute of America). 

This wealth of experience led me to envision a way to share this information with the chimney industry and anyone interested in internal chimney inspections, culminating in the following book. The Chimney Scanning & Inspection Guide.
Within this book is a brief outline:

• Where to start – Use IRC, NFPA 211, local codes, or the manufacturer’s installation instructions.
• Where to put drop cloths and prepare the area for the inspection
• How does scanning chimneys fit within the Levels of Inspection (NFPA 211)? Where do the Levels of Accessibility fit into all this?
• How do structure integrity and flue condition compare to what is the ideal chimney in the code books?
• What is happening within the flue and the chimney?
• What is the probable cause of the defect or symptom, along with an explanation?

Operating a chimney camera using the proper techniques and observation skills should produce more answers regarding the flue’s condition rather than presenting more questions. Since there are many types of installation, we segmented this book into modules to provide a step-by-step approach to chimney scanning by chimney type. The modules include:
​
• Scanning a Masonry Chimney and Fireplace
• Scanning a  Masonry Chimney and Fireplace with an Appliance (Hearth Stove & Insert)
• Scanning a Masonry Thimble Chimney Serving an Appliance(s) (Solid Fuel or Liquid Fuel(s)
• Scanning a Prefab Chimney and Fireplace
• Scanning a Prefab Chimney Serving an Appliance (Solid Fuel or Liquid Fuel(s)

Each installation type offers its unique challenges. We detail the differences between types of installations, including conditions to be alert for and the typical defects for each. The training modules listed above tell you the best access points and offer a step-by-step assessment process for home protection, defect diagnosis, and cleanup. If you would like more information about our books, click here. Otherwise, continue reading our blogs to learn about your interests.
Orange colored terra cotta flue tiles are all misaligned. Some soot is visible.
Looking at the interior of the 5’ chimney, it is appears the builder didn’t use mortar, which led to misaligned tiles. There are some cobwebs. The black marks may be scorch marks or soot. It’s hard to tell without a closer look.
The exterior of the flue tiles have large gaps where the tile is broke. Soot is visible.Picture
When I opened the door to the 5’ chimney, the gaps in the flue became visible. Additionally, there was a tarlike creosote deposit on the exterior, which likely came through the hole and the missing mortar. More defects were inside the flue that were missed. We then asked attendees to use our camera to scan the interior of the flue, which revealed more defects.
A spiral bound book is opened to two chimney drawings with a flue tile and length of prefab chimney.
Our Interior Chimney Scanning Guide features over 400 images and 200 pages. There's nothing like it in the chimney industry!
The spiral bound book is opened to 2 installation drawings. One for a woodstove, the other for a furnace.
This guide features a lot of technical information and five modules: Scanning a Masonry Chimney and Fireplace • Scanning a Masonry Chimney and Fireplace with an Appliance (Hearth Stove & Insert) • Scanning a Masonry Thimble Chimney Serving an Appliance(s) (Solid Fuel or Liquid Fuel(s) • Scanning a Prefab Chimney and Fireplace • Scanning a Prefab Chimney Serving an Appliance (Solid Fuel or Liquid Fuel(s)

How a New Prefabricated Chimney Section Should Look

1/6/2025

1 Comment

 
​Prefabricated chimneys have been in use for decades as a Listed, accepted substitute for masonry chimneys. Prefabricated chimneys and venting product installations can vary based on the product, the installation type, and the appliance type. It’s important that these chimneys be inspected annually and cleaned. Inspecting the chimney with a Chim-Scan® Internal Evaluation System is a great way to ensure the chimney is in a continued operational condition.

All manufacturers of prefabricated chimneys test their products at a recognized laboratory to a test standard.is the creator of the test standards. Tests include several challenging factors the chimney must pass, including temperature, duration, torsion, chimney brushing, and rain tests, to name a few. 

Once the manufacturer successfully passes the test, the product installation instructions must be approved, each component properly labeled, and an agreement must be signed for random manufacturing plant inspections. Then the manufacturer is offered the Listing. 
The manufacturer may choose to offer a training program for installers. The installer's job is to install the chimney or vent, using the listed components to recreate it in the same manner as the manufacturer's installation during the testing for listing or approval. 

A new chimney pipe is shiny inside and should not have any denting or damage inside or outside. The joints should connect firmly, and all supporting components must be used. After a new chimney pipe is put into use, it must be inspected at least annually and cleaned as specified in the maintenance section. Again, the best way to see inside a series of chimney sections is with a Chim-Scan® Internal Video Inspection System.
​
With proper installation, usage, and maintenance, your prefabricated chimney system should give you years of use. After all, they have been used to vent fireplaces and hearth appliances for decades.

This shows how a new pipe should look. This is referred to as a double wall chimney section. Insulation is sandwiched between the inner and outer walls.

This is what a severely damaged pipe looks like.

When to use IRC and NFPA 211 for Chimney Inspections
Both the International Residential Code (IRC) and the National Fire Protection Association (NFPA) 211 books provide information on building chimneys, fireplaces, and appliance installations. Which book should I use for chimney inspections? The IRC and NFPA 211 both cover new construction of chimneys, fireplaces, and appliance installations. However, NFPA 211 goes one step further, offering a process for inspecting chimneys, fireplaces, and appliance installations since we see the world of chimneys and fireplaces after operating. The question above is commonly debated within the chimney industry.
Are you wondering which to follow for new construction? Most states require the use of IRC, and a few require NFPA 211. Some states have their own building codes and some areas within a state have their own codes. Then there are exceptions such as historical areas. Always check locally because there may be additional local codes required above and beyond IRC or NFPA and even state codes.
When it comes to prefabricated chimney and fireplaces, the installation instructions must be used. These instructions can usually be obtained online if you know the model number. The same goes for appliances. If you need to call the manufacturer’s help desk for technical assistance, be sure to also have the serial number. The manufacturer (and their installation instructions) must be followed for installation and supersede IRC and NFPA 211.
We suggest obtaining an IRC or NFPA 211 book if you don't already own one. If your area abides by IRC for new construction, you will still need NFPA 211 for access and inspections. Additionally, you may need copies of local codes and historical district codes. As a chimney technician or inspector, it's up to you to determine if the chimney, fireplace, and appliance installations are operational-ready based on inspection criteria. Your customers count on it.

Gear Up for National Fire Prevention Week - October 6-12, 2024

9/12/2024

National Fire Prevention Week is just around the corner. Are you ready to promote your business? After all, as a chimney inspection business, you are already part of a fire prevention team, which is the chimney and hearth industries. According to the U.S. EPA, the leading factor contributing to home heating fires was failure to clean, principally creosote from solid-fueled heating equipment, primarily in chimneys (NFPA). How can you advertise your business while educating your customers and the public? Here are some ideas:
Bring it “online”! – what to do during a chimney fire!
Most customers have no idea what a chimney fire is. They don’t know how to watch for an increase in the draft, the clinking sound of breaking clay tiles, the creosote falling into the firebox or oozing into the appliance, and the loud whirring sound as the draft increases. They need to understand that while their chimney may be constructed of masonry or a prefab system, these are designed to vent combustion products and not necessarily the high temperatures and effects of a chimney fire. Post this information on your website and use social media to spread the message. Show your Chim-Scan® Camera in use and the pictures it produces. They may have heard about it on TV or at another venue, but not everyone understands the needs and steps they should take to protect their home and family.
Show it off! - Your van parked in strategic spots, employee uniforms, etc.
During fire protection week, there will be news with fire statistics, firemen (and women), fire stations, and more. Park your vehicle in a public place. At lunch, it might be a fast-food business. Park it where people driving by can see it. Consider putting a QR Code on your van so they can quickly scan your site while waiting for the traffic light or before heading back to work. Leave it out to advertise in other secure locations when you or a team member is off work.  
Teach it! - Kids, civic groups, etc.
Civic groups and kids’ groups are always looking for speakers to put on a presentation. Does public speaking make you feel uncomfortable? You must remember that you are providing a service that has helped reduce the number of chimney fires and likely saved lives. Pass out coloring books or flyers to the attendees. The National Fire Protection Association has a wealth of informational brochures, games, and coloring pages on its website. Go to www.nfpa.org, then to Events, and click National Fire Prevention Week. 
Own it!  - Newspapers, radio talk shows, TV Stations, etc.
Offer to demonstrate your Chim-Scan® chimney imaging camera. TV shows and newspapers love to have local news during this event and filming a chimney inspection adds interest. Radio talk shows are another great venue for spreading the word this week. Most homeowners don’t know the difference between types of creosote. They likely don’t understand that an all-night burn isn’t always a good idea. You own the information; share it!
Give it your all! - Drawings for smoke extinguishers, smoke alarms, CO Alarms, etc.
During Fire Prevention Week, run daily drawings on your social media accounts. If they “like” your posts, put them in the hat for a drawing for a free fire extinguisher, smoke alarm, and/or CO alarm package.
National Fire Prevention Week is one of our industry's busiest times. This year’s theme from the National Fire Protection Association® (NFPA®) is “Smoke alarms: make them work for you!™” During this time, fire prevention is on people’s minds, and some fire departments may talk about chimney or heater fires. It is a great chance to tell your story and share some of the knowledge you’ve gleaned as part of the chimney fire prevention team.

Who is Estoban? What is a Chim-Scan® Camera?

​Driving down a little highway amidst the rolling fields of corn and soybeans outside of Fairfield, Iowa, you might think of the movie “Field of Dreams.” You might be surprised to learn that a specialized, high-tech manufacturing facility is nestled amidst some pine trees with cows grazing in the fields just off the highway. What looks like a fancy, big red machine shed houses the manufacturing operation that built the first chimney camera in the world. As you move around the corner, you see a building attached to it that houses the office, with many lovely windows and an inviting porch. Next to it sits the home of the first man and the first woman to scan a chimney with a camera worldwide. But let’s start at the beginning.
Tom Urban met his wife Esther while he was working on a dairy farm in 1975, and they were married a year later, in 1976, after Tom graduated from college with a degree in Dairy Sciences. Being an adventurous couple, they set off to Swaziland, Africa, for a stint in the Peace Corps (who does that?). When they returned, they saw an ad and decided to open a chimney-sweeping business.
They swept chimneys and encountered glazed flues and flues damaged by chimney fires. They searched for a source of chimney liner pipe and began relining the damaged flues. “There weren’t any commercial liners available for chimney sweeps,” notes Esther. “We had to go to Chicago to buy liner!” Tom learned about wrapping a liner with a ceramic blanket from the Chicago Manufacturer, although it was not used for chimney liner applications. “I brought the concept of wrapping stainless liner with a ceramic blanket to our industry,” Tom states proudly.
Tom partnered up with an insurance adjustor with a masonry background and began to see the need for a better way to observe chimney interiors. In 1983, at the National Chimney Sweep Guild Show, he talked to other sweeps about his concern that they may not see all interior flue defects with a flashlight, but most sweeps thought they were catching everything. Tom recalls, “I’m thinking, I’ve got 20-20 vision, but I know I’m missing things! Coming out of the convention, crossing the bridge out of St. Louis, I vowed to have a chimney camera system before the next convention!”
After a year of research, Tom finalized a black-and-white chimney camera and monitor system. With the technology of the times, a system the size of a footlocker with wheels was required to move it in and out of the customer's home. In 1984, at the NCSG convention in Washington DC – Chim-Scan® was shown for the first time to a national audience. It was pronounced a showstopper by CNN News Channel, and many thought Tom was nuts for sticking a camera in a chimney, but time has shown he's an innovator.
Estoban stays current on new technology, but with the rise of disposable technology, they have become even pickier about what they put in their equipment. They only buy and work with commercial electronics, which tend to move slightly slower than consumer electronics. They use Commercial because it has to workday after day, with the option of repair. Shelley explained, "One would never trust a sewer company if they showed up with a teeny tiny camera hooked up to their phone. That stuff is cool and cheap but cannot withstand everyday abuse." For those who might not know, Estoban repairs and upgrades Chim-Scan® Units as long as the parts are available. Currently, they can upgrade most units built since 2010.
When you look at a Chim-Scan®, you are looking at a controller that Alicia or Shelley wired, a Case that Tom or other staff built, a reeler that Esther or Therese wired, and a camera that Tom or another employee built. Alicia and Shelley are small component assemblers who help keep the rest going.
In 2016, a new addition, or backroom, was added. The latest addition starts with a 9 ft ceiling and then jumps to a 16 ft ceiling, allowing us to build a mezzanine. The Back half of the 'Backroom' is Tom's Chimney Lab. There is a masonry fireplace, prefab insert, and a masonry thimble chimney; the mezzanine allows roof access to these chimneys just by climbing a set of stairs. Watching their videos, you'll see the Lab; they use it daily to test repairs, new units, and new products.
New technology has been implemented into the manufacturing operation, such as 3D printers, which are now used to print the stabilizers for the cameras, freeing up the CNC machines. This also allows continual parts improvements, and there is no waiting on parts, which some manufacturers had to do in 2020 and 2021. Shelly creates the 3D drawings and designs all 3D printed parts on her computer.
Tom's favorite tools are his four CNC machines; they have sped up production 100-fold. Parts are constructed in-house for the Chim-Scan® Units. Tom shares these tasks with other employees.
As stated before, Estoban also repairs the equipment it builds; this involves the oldest employee, Marvin, who does 80% of the repairs and many of the upgrades. Ray is the shipping and receiving guy. Every package that comes in gets unpacked and photographed by Ray, who then cleans it within an inch of its life and hands it over to Marvin. Esther, Alicia, and Tom pick up the other 20%. Once a Repair or Upgrade is complete, it gets reviewed, tested, and tested again by Ray or whoever is free. It is then cleaned again (as fine soot is worse than glitter to get rid of), photographed, boxed up, and shipped out.
Once new units are complete, they 'sit' for 8 hours, being turned on and off, running for a few minutes to hours, are taken to the Lab, and run up the chimneys to test every part of the unit. They are then photographed, packed, and shipped so we can see what they're talking about when a customer calls.
Some may ask, with the listed jobs above, who answers the phone? Shelley and Esther are the voices of Estoban; they cover customer service, sales, and tech support.
Estoban also has the benefit of being a pet-friendly workplace. If you stop by for a visit, you receive a greeting by the little booming voice of Bella the Wheaten terrier, and the dismissive glance of Binx, the cat, aka Inspector 12. Solomon and Bella oversee internal security, employee well-being, and occasional photo shoots. Max oversees everyone's work, sending random emails (touch screen computers) and the rare photoshoot.
Speaking of the past, you may ask, What about the future? Shelley will run Estoban if Tom and Esther retire.
She has grown up in the business and currently wears a lot of hats:
  • She can build a camera and monitor system starting at zero.
  • She troubleshoots camera issues.
  • She designs all 3D printed parts on her computer and then tests and evaluates them.
  • She manages all of the marketing at Estoban, including being the webmaster.
  • She can step into any position within the company at any time to fill in as needed.
  • She is a key decision-maker along with Tom and Esther.
Shelley is set to maintain the Chim-Scan® standard of excellence and keep growing the business along with leading-edge manufacturing concepts and the latest technology. Will Tom and Esther retire? They may eventually take more time off with shortened hours to fit in more recumbent bicycle rides or time off to hit some “bucket list” items, but they will likely continue to work in the business because when you love what you do, it’s not work. It’s a passion.

Tom, Esther, and Shelley Urban are all smiling.

How to Build Your Chimney Inspection Form

8/29/2023

0 Comments

 
Picture
​A chimney inspection involves peeling back many layers of investigation, almost like peeling an onion. Just as each layer of onion is a leaf that helps feed the plant, each part of the chimney investigation peels back another layer, revealing transitions and potential defects. Just as every onion is unique with its number of layers and thickness, each chimney is unique and differs depending on many factors such as type, fuel, usage, construction, etc. If you could build your inspection, where would you start?
The first consideration we could start with is the type of chimney we will inspect. Does it fall within one of the following categories?
  • A Masonry Fireplace with or without Gas Logs?
  • A Masonry Fireplace Chimney venting an insert or hearth stove?
  • Masonry Chimney with a thimble connection venting a solid or liquid fuel(s) appliance(s)?
  • A prefabricated fireplace?
  • Listed prefabricated chimney venting a solid or liquid fuel(s) appliance(s).
Once you narrow it down to the type of chimney and what it is venting, then you can peel back another layer of common building components such as:
  • Brick, block, or stone
  • Clay flue tiles or prefabricated chimney sections
  • Exterior chimney mortar
  • Interior chimney mortar
  • Prefabricated braces and stabilizers for a chimney with or without a chase.

Picture
​Peel another layer back and look at more specifics:
  • Connector pipe and adaptors
  • Insulated thimbles for masonry
  • Thimbles and supports for prefabricated chimney
  • Components such as supports, offsets, locking bands, attic shields, etc., for prefabricated chimneys.
The next layer you could peel back is specifics about the appliance, such as:
  • Is it a fireplace?
  • Is it venting a solid-fuel appliance?
  • Is it venting a liquid-fuel appliance?
  • Is it burning oil, gas, or solid fuels?
  • Is it a furnace, boiler, or gas water heater?
  • Is it a hearth stove, free-standing stove, or insert?
 
The next layer could be appliance specifics such as:
  • Fireplace interior construction and clearances
  • Fireplace facing and hearth construction and clearances.
  • Appliance mounting (stove boards) and wall protection clearances.
  • Gas appliance installation requirements include clearances and items like a hot water coil.
  • Oil appliance installation requirements include clearances and items such as a barometric damper, hot water coil, etc.

Picture
​Depending on how far down you want to peel the onion, we have modules available to peel right down to the core. What you find within the first couple of layers usually determines how far you need to go with each layer, peeling back more evidence regarding fireplace and appliance use and how the products of combustion reacted as they entered and passed through the chimney.
Whatever your desire in an inspection process for documentation, we can create it. Whether it is a Level 1, 2, or 3, we promise your eyes won’t water when you see the cost.
