How DuraFlex Products Fail – and How We Fix Them

We work on enough DuraFlex liners in Brooklyn, NY to know which problems repeat and which ones are rare. Here’s what we see most often:

• Creosote buildup on the corrugated inner wall (DuraFlex 316Ti and 304 series). The spiral corrugation that gives DuraFlex its flexibility also gives creosote more surface to grip. We use poly brushes sized to the liner’s exact inside diameter, never wire brushes that would score the stainless. After sweeping, we check for glaze at the corrugation peaks, which is where Stage 2 creosote hides.
• Pinhole corrosion around the tee connection (DuraFlex stainless liners). In Brooklyn row houses and brownstones, we regularly find moisture settling at the tee base. Condensation from short bursts of burning mixed with our humid summers creates a corrosive microclimate. We catch it early during sweeps by inspecting the tee with a camera before it becomes a full perforation.
• Loose or misaligned couplers after years of thermal cycling. DuraFlex sections connect with couplers that expand and contract with every fire. After five or six heating seasons, a coupler can walk slightly out of alignment. We check every joint during a sweep and tell you if any section needs re-seating. It’s usually a simple fix that prevents a draft leak later.
• Baffle and rain cap blockage in exposed liners. Brooklyn flat roofs and chimneys that don’t clear surrounding parapets create wind patterns that drive debris into the cap. On DuraFlex systems with older caps, we’ll often find leaves, pigeon nesting material, or soot-caked mesh. We clear it during the sweep and recommend a screened cap if the mesh is compromised.
• Creosote bridging at the offset elbow (DuraFlex elbows, 15 and 30 degree). Wherever a liner bends, creosote accumulates faster. In tighter Brooklyn chimneys with multiple offsets, we see bridging at the elbows long before the straight sections look dirty. Our sweeps include extra attention at every bend, and we photograph the before and after so you can see it for yourself.

Our DuraFlex Chimney Sweep Process

1. 1
   You call (607) 695-6218. A live person answers and books your sweep. No voicemail trees.
2. 2
   We arrive with shoe covers and drop cloths. The C.A.R.E. values kick in at the door: we cover your floors, ask before moving anything, and keep walkways clear for kids and pets.
3. 3
   We inspect the liner by camera before brushing. On DuraFlex systems, we’re looking at couplers, tee connections, and the corrugated wall. You get to see the images.
4. 4
   We sweep with poly brushes matched to the liner diameter. No wire brushes on stainless. Creosote and soot drop into a vacuum-sealed HEPA filter so nothing drifts into the room.
5. 5
   We decide on any necessary parts. If a coupler is loose or a cap is damaged, we recommend OEM DuraFlex replacements where warranty matters, or quality aftermarket equivalents when the liner is older and the budget matters. You get the choice in writing before we touch anything.
6. 6
   We test, photograph, and clean up. We run a draft check, show you the after photos, and snap a picture of the clean work area before we leave. Every job is backed by our 365-Day Done Right Promise.
