How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW (stainless wall) liners in pre-2018 installations often show seam separation where the Downingtown freeze-thaw cycle works the flue joint. We find this during camera inspection as a hairline gap at the collar connection that widens after the first hard January. Our fix: cut back to sound metal, install a DuraFlex-compatible factory coupling, and pressure-test before the cap goes back on.
• DuraFlex Pro liners with premature corrosion at the smoke chamber trace to sulfur-laden coal or high-efficiency gas exhaust pooling in the offset. The Pro’s 316Ti alloy resists acid well, but it can’t outlast standing condensation. We sleeve the damaged section with OEM DuraFlex Pro or, when supply runs thin, a 316Ti equivalent from our Haven network that matches wall thickness exactly.
• DuraFlex relining systems with failed top termination collars let water run straight down the annular space. In Downingtown’s older colonials along the East Brandywine corridor, we’ve replaced dozens of these collars after ice jacking loosened the seal. We source Gelco or Famco termination fittings when DuraFlex OEM stock is backordered, documenting the substitution for any future warranty claim.
• DuraFlex DW (double-wall) factory-built chimney sections with spalling exterior brick aren’t a liner problem, but they mask one. The DW system’s air-cooled design drops flue gas temperature, which increases condensation in the outer wall and accelerates mortar decay. We repoint with Type N mortar matched to the existing, then verify the DW inner wall hasn’t corroded through with a scope inspection.
• DuraFlex flexible liners installed too tightly in offset flues crease at the bend and trap creosote in the fold. This is installation error, not material failure, but it’s common enough that we treat it as a pattern. We extract the liner, ream the offset with a masonry grinder if the flue tile allows, and reinstall with proper tension.

Our DuraFlex Chimney Repair Process

1. 1
   Call and schedule. A live person answers, day or night. We book a Level 2 inspection with camera scan.
2. 2
   Inspection and documentation. Corrine or one of our techs runs the camera, records the flue condition, and marks DuraFlex model numbers and manufacturing dates visible on the collar or label.
3. 3
   Written price and scope. Before any repair begins, you get a written price, a written scope of work, and a written warranty. Clause 1 of the Haven Standard.
4. 4
   Parts decision. We stock common DuraFlex fittings and source from our Haven buying network. If OEM isn’t available, we quote the quality aftermarket equivalent and note the substitution.
5. 5
   Repair and test. We complete the work, run a final camera pass, and pressure-test liner connections where applicable.
6. 6
   Photo record and follow-up. You receive the documented photo record, same as our 38,000+ jobs since 2009. The 365-Day Done Right Promise begins now.

Why Downingtown Homeowners Call Level Two Chimney Downingtown for DuraFlex Work

We’ve been running cameras and brushes through chimneys across Downingtown for years, including the older colonials along the East Brandywine corridor where DuraFlex relines are common. Corrine Halstead trained in building trades and HVAC systems at SUNY Westchester Community College before working flues and fireboxes from the ground up, and she built this crew to name what the camera finds before naming a price. The camera doesn’t guess. Neither do we.

We also service HeatShield and Gelco systems, so when a DuraFlex part is backordered, we have alternatives that don’t leave you waiting through burning season. Every tech is background-checked and uniformed, license number on the page, with a text when we’re on the way. The 365-Day Done Right Promise is stamped on every job.
