Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Flint Chimney Sweep Is Duncanville’s Preferred Chimney Inspection Company
We carry a written guarantee on every repair we perform, and we have been at this since 2002 as part of the Garrison Partners family of independently owned chimney service companies. That matters because the work done on Duncanville chimneys should be backed by something besides a handshake. The Garrison Standard is what we call the operating code every Garrison Partners location follows: written price before any work begins, uniformed and background-checked technicians on site, and a live person answering the phone 24 hours a day.
Duncanville homeowners call us because the inspection is more than a glance up the flue. We document everything. A standard report includes photographs of the firebox, damper, smoke chamber, flue liner, and exterior crown, plus a written summary of what we found and what we would actually do about it if the house were ours. Hank Delano, who leads Flint Chimney Sweep, holds every inspection to that standard.
Our Chimney Inspection team services Duncanville as part of our regular DFW route scheduling, which means we know the local housing stock without having to guess. When you describe a 1970-something brick ranch off Main Street or a newer frame build near Greenbriar Drive, we already have a working picture of what the chimney looks like before we arrive.
Fireplace Inspection in Duncanville
Fireplace Inspection in Duncanville means checking the entire system that carries smoke and exhaust out of your living room: the firebox where the fire actually burns, the damper that opens and closes the throat, the smoke chamber above it, and the flue liner that carries gases to the top. A standard fireplace inspection here runs $129 – $249 and includes a camera check of accessible surfaces. If your home is pre-1980 with original masonry work, we will spend extra time on the mortar joints and crown, because those are the failure points Duncanville’s clay soil and freeze-thaw here in North Texas tends to exploit.
Visual and Camera Documentation
Every inspection includes a camera run through the flue when the level of inspection calls for it, and photographs are part of the standard report. You get to see the hairline crack in the liner or the spalled brick rather than taking our word that it exists. That photo report is the whole point of hiring an inspection company instead of a guy with a flashlight.
The Straight Answer on Repairs
Not every cracked firebrick needs replacing this week. Some do. Our written report separates findings into what we would address before the next burn and what can safely wait another season, and we put both lists in plain English.
Chimney Inspection Services in Duncanville
Chimney Inspection Services in Duncanville cover three levels defined by the NFPA 211 standard. Level 1 is the annual visual check we recommend for chimneys that have been burning fine with no changes to the appliance or the flue, and it runs $129 – $249. Level 2 adds a camera scan of the full flue interior and is what we recommend after a real estate transaction, a chimney fire, a lightning strike, or any change to the heating appliance. Level 2 in Duncanville runs $289 – $389. Level 3 is reserved for cases where a Level 2 already found something that needs to be opened up, and we scope Level 3 pricing specifically to the home.
Flue Camera Scan
The camera run is what separates a real inspection from a visual once-over. We insert a camera up the flue and record every joint, looking for cracked liners, blown-out mortar, animal nesting, and creosote that has glazed into tar. If the camera cannot navigate a bend or obstruction, we tell you that too.

Pre-Purchase and Real Estate Inspections
If you are buying or selling a home in Duncanville, a Level 1 visual check on a pre-1970s masonry chimney is usually not enough. The transaction should include a camera inspection of the flue liner and smoke chamber, because that is where expensive problems hide. Realtors booking the cheaper visual-only check are common; we will tell you directly when the property needs more.

Trusted Brands We Service in Duncanville
We work with professional-grade chimney products from DuraFlex and Olympia Chimney, and we stock common replacement parts that fit the factory-built fireplaces built into many Duncanville homes. When a newer unit needs a cap, a chase cover, or a flue liner section, having the parts on hand means the repair does not stretch into a second visit. For older masonry chimneys, we spec Famco and Copperfield components where the job calls for them. We name the brands because you should be able to verify what goes into your chimney, and because no one should take “quality parts” on faith alone.
Common Chimney Inspection Problems We See in Duncanville Homes
- Spalled brick and cracked crowns on 1960s – 70s masonry chimneys. Duncanville’s older brick ranches, especially around Harrington Park and the neighborhoods off Greenbriar Drive, were built with single-wythe masonry chimneys. Decades of North Texas freeze-thaw cycles crack the crown, water gets in, and the brick faces begin to pop off. We see it on roughly half the pre-1980 chimneys we inspect.
- Rotted flue liners in factory-built fireplaces. Newer Duncanville construction leaned on factory-built metal chimney systems, and those fail differently. The inner liners corrode, the caps rust through, and water channels straight down into the firebox. A visual glance from the roof rarely catches this; the camera does.
- Creosote that has glazed into third-degree tar. First-degree creosote brushes out with standard sweeping. Third-degree creosote, which forms when fires burn cool or green wood over multiple seasons, hardens into a glaze that no brush removes. By the time we see it, the flue liner underneath is often already compromised.
- Animal nesting and debris in chimneys that “barely get used.” Duncanville homeowners who skip the annual inspection because they rarely burn are the ones most likely to find a bird or squirrel nest, dead leaves, or a cracked cap on inspection day. Weather and animals work on a chimney whether or not you light a fire.
Pricing for Chimney Inspection in Duncanville, TX
A Level 1 inspection in Duncanville runs $129 – $249. A Level 2 inspection with a full camera run runs $289 – $389. The difference comes down to what we are looking at and how thoroughly we need to document it. Homes with original masonry chimneys and no recent inspection usually warrant the Level 2 camera scan, which adds time but gives you a record of the flue’s actual condition rather than a best guess from the rooftop. Every quote is written and delivered before any work starts, and the number on that quote is the number on the invoice. Call (830) 251-4560 for a free estimate on the specific level your chimney needs.

FAQs About Chimney Inspection in Duncanville
The NFPA 211 standard calls for an annual Level 1 inspection, and we agree with it because the freeze-thaw here works on chimneys whether you burn or not. If you burn more than a couple of weekends a season, you should get the camera run at least every other year. Call (830) 251-4560 and we’ll tell you which level applies to your chimney.
Level 1 is a visual check of accessible surfaces, for chimneys that have not changed since their last clean bill of health. Level 2 adds a camera scan of the full flue and is required after a real estate transfer, a chimney fire, a lightning strike, or any change to the appliance. Level 3 is invasive, opening up a section of the chimney or flue to see behind the surface, and we only recommend it when a Level 2 already found something that warrants it.
Yes. Every inspection report includes photographs of what we saw, including camera stills from inside the flue when we ran one. You see the same crack we saw, and you get a written explanation of what it means and what we would do about it.
Yes, and we say so in writing. Not every crack is a fire hazard this week, and we split every report into what needs attention before the next burn and what can wait. In Duncanville we ran a Level 2 inspection on a 1970s ranch off Greenbriar Drive where the homeowner was smelling smoke in the back bedroom on cold starts. The camera showed a cracked flue liner joint and a warped damper that was letting draft stall in the smoke chamber. We shot photos of every joint, wrote up the spalling crown and the liner breach, and gave them a straight answer that the crown could wait until spring but the liner could not. That is how we report every inspection.
We do. Factory-built metal chimney systems fail differently than masonry, and our technicians carry the DuraFlex and Olympia Chimney components to repair them properly. If your newer Duncanville home has a metal fireplace, we inspect the chase, the cap, and the flue liner with the same camera standard we use on masonry.
