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 Fort Worth Homeowners Choose DuraFlex Chimney Cleaning
DuraFlex service in Fort Worth is an independent chimney cleaning we provide at Kindling Chimney Fort Worth, and it covers everything from standard creosote removal on 316L flexible liners to detailed Level 2 inspections on Pro 316Ti rigid systems. What separates our DuraFlex work is simple: we know where these liners fail in North Texas before we ever put a camera up the flue. We are not a DuraFlex dealer or authorized service center, and we’ll say that plainly. We’re an independent chimney company that has cleaned and repaired enough DuraFlex liners across Fort Worth to recognize factory seams, installer mistakes, and weather-related corrosion on sight. If you need a straight answer about your DuraFlex liner, call (682) 382-9934.
Why Trust Kindling Chimney Fort Worth for Your DuraFlex Chimney Cleaning?
Danny Cortes, our owner, spent the better part of two decades cleaning and inspecting chimneys across Fort Worth and nearby areas like Duraflex service in Arlington before starting Kindling. He’s pulled DuraFlex liners out of 1920s bungalows in Fairmount and newer builds on the city’s edge, and he’ll tell you the same thing every time: a DuraFlex liner is only as good as the installation and the annual maintenance behind it. Our technicians are background-checked, uniformed, and trained to follow the C.A.R.E. values on every job: shoe covers and drop cloths go down on arrival, nothing is moved without asking, and a photo of the clean-up is taken before the crew leaves. When we work on a DuraFlex system, we use OEM couplers, top plates, and termination kits wherever the liner’s certification depends on it. For wear items like appliance connectors, we install code-compliant aftermarket parts from Heat-Fab or Selkirk. That’s not corner-cutting; that’s knowing which parts matter and which ones don’t.
Every DuraFlex cleaning or repair we do is covered by our 365-Day Done Right Promise. If the work isn’t right, we make it right. No fine print. The Cedarwell Care Promise sits underneath that: a written price before any work starts, shoe covers and drop cloths on every visit, and a photo of the clean-up before we leave. Families with kids and pets never have to guess what the bill will be or what the crew will do inside the house. That’s the whole point of how we work.

Common DuraFlex Chimney Cleaning Problems We Fix in Fort Worth
- Seam separation at pop-rivet points on 316L flex liners. Fort Worth’s hot summers and winter freezes make the stainless expand and contract over and over. On DuraFlex 316L flexible liners, the pop-riveted seams are the first point of failure. We regularly find separated seams 10 to 15 feet up the flue, where flue gas has been escaping into the chase for months. A Level 2 camera inspection catches this early; a basic sweep often misses it.
- Pinhole corrosion on aluminum liners used with gas appliances. DuraFlex aluminum flexible liners are rated for gas, but they’re thinner than stainless and they corrode at the corrugation valleys. If a gas fireplace is used heavily and the liner isn’t swept annually, pinholes can form within five years. We see this constantly in Fort Worth homes with pre-fab fireplaces from the 1990s and 2000s. Once pinholes start, the liner is done; patching aluminum is a temporary band-aid.
- Torn couplers on Pro 316Ti rigid sections. The DuraFlex Pro 316Ti rigid liner uses male/female couplers that should be lubricated before joint assembly. When an installer skips that step or forces the sections together, the couplers tear. The result is a misaligned seam that collects creosote and eventually restricts draft. Our techs check every coupler during a cleaning, not just the visible ones.
- Ovalized flex liners around tight offsets. Fort Worth has a lot of two-story masonry chimneys with sharp bends. When a 6-inch DuraFlex flex liner gets pulled around a tight offset without proper support, it ovalizes. The liner narrows, draft drops, and smoke rolls back into the living room. We see this on older Fairmount and Ryan Place homes where the flue makes an awkward jog near the roofline.
- Creosote glazing behind separated seams. This is the one that keeps Danny up at night. When a DuraFlex seam separates even slightly, creosote vapor condenses behind it and hardens into a glassy glaze. A normal brush won’t touch it. We use a rotary whip to break up glazed creosote, then camera-verify that the liner wall is clean before we call the job done. If the seam separation is beyond two isolated spots, we recommend full liner replacement.
DuraFlex Parts & Our Repair-vs-Replace Approach
We stock DuraFlex OEM couplers, top plates, rain caps, and termination kits in our Fort Worth shop so we can complete most repairs in one visit. When a liner’s existing certification matters, we use genuine DuraFlex parts. For wear items like appliance connectors, we install code-compliant alternatives from Heat-Fab or Selkirk; they do the same job and they’re easier to source quickly.
Here’s where we’re honest with Fort Worth homeowners: if your DuraFlex liner shows separation or pinholes beyond two isolated spots, we won’t patch it. Field repairs on double-wall flex often create hidden leak paths that look fine on the outside and leak on the inside. A new liner costs more today, but it’s cheaper than a chase fire or a carbon monoxide problem six months from now. Call (682) 382-9934 for a written estimate before you decide.
Our DuraFlex Service Process – Step by Step

- 3
Installation or replacement with OEM parts where it matters. Couplers, top plates, rain caps, termination kits. We use DuraFlex OEM for certification-critical pieces and code-compliant aftermarket for everything else.

FAQs – DuraFlex Chimney Cleaning Service in Fort Worth
Yes, we clean uninsulated DuraFlex liners regularly in Fort Worth, but we’ll be upfront about what that means. An uninsulated liner runs hotter on the outside and cooler on the inside, which can accelerate creosote condensation, especially with a wood-burning fireplace. During your cleaning, we’ll note the condition of the liner and let you know if insulation would help your specific setup. Call (682) 382-9934 and we’ll take a look.
No. We don’t patch tears in DuraFlex liners, especially near the top plate. A tear near the termination point is a leak path for flue gas and an invitation for water intrusion. The right fix is replacing the top section of the liner and the top plate, which we can usually do as a partial repair if the rest of the liner is sound. If the tear is one of several issues, those pop-rivet holes and seam separations tell us to replace the liner entirely. We’ll show you the camera footage so you can see exactly what we’re seeing before you spend a dollar.
Yes. Rigid Pro 316Ti liners have smooth interior walls and fixed couplers, so we use a different brush configuration and pay close attention to the coupler joints where creosote tends to collect. Flex liners, with their corrugated walls, need a rotary whip more often to break up buildup in the valleys. We adjust the cleaning method based on what we see in the camera inspection, not by habit.
Gas fireplaces still produce acidic condensation that eats away at aluminum liners over time, especially in Fort Worth’s humid summers. The condensation mixes with dust and soot from the burner, forming a corrosive film that accelerates pinhole corrosion. An annual look at the liner catches this before you’re dealing with carbon monoxide in the house. If you haven’t had your gas liner checked in a while, call (682) 382-9934 and we’ll get you on the calendar.
Yes, in most cases. We can remove the old liner if it’s intact enough to pull, or break it out in sections if it’s damaged. Then we run the new DuraFlex liner through the existing flue passage, insulate it if needed, and secure it at the top plate and appliance connector. The process is straightforward, but we’ll want to do a quick inspection first to make sure your chimney structure can handle the new liner properly.
Most standard Duraflex repair in Burleson and Fort Worth area chimney cleanings run between $189 and $350, depending on the liner type, the level of creosote buildup, and whether we need a rotary whip or standard brushes. A Level 2 camera inspection adds $125 to $200. Liner replacement is a bigger number, obviously: a full 316L liner install typically runs $1,800 to $3,500 in this market, but we’ll give you a written price before any work starts. Call (682) 382-9934 for an exact quote. Estimates are free, and we won’t pressure you into anything.
No. We are an independent DuraFlex service provider in Fort Worth, not an authorized dealer or warranty center. That means we’re free to recommend what’s actually right for your chimney without a brand agenda. We use OEM DuraFlex parts where certification matters and code-compliant aftermarket parts where it doesn’t. You get the truth, not a sales pitch.
