How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW (Stainless Wall) liners crack at the flex points above the smoke chamber. In Los Angeles, thermal cycling from our dry Santa Ana days followed by cool coastal evenings fatigues the corrugations faster than steady-cold climates. We cut back to sound metal, install a factory-compatible splice with a DuraFlex-approved coupling, and pressure-test before we leave.
• DuraFlex AL (Aluminum) liners corrode at the cap interface where condensation pools. These show up in older Mid-Century chimneys around the Valley where original clay flues were retrofitted in the 1990s. Aluminum doesn’t forgive standing moisture. We replace the damaged upper section with compatible DuraFlex AL or upgrade to SW if the appliance allows, and we reseat the cap with proper drainage.
• DuraFlex DSA (Double-Wall Solid Pack) develops mortar voids between the liner and surrounding masonry. The outer wall hides the gap until you smell smoke in an upstairs bedroom. We pull a Level-2 camera, document the void with photos you can see, and pump HeatShield Cerfractory Foam or perform targeted repointing depending on void size.
• DuraFlex relining collars separate at the thimble connection on wood-burning inserts. This is the failure that sets off CO detectors in Mount Washington and Highland Park older homes. We remove the insert, inspect the collar for fatigue cracking, replace with OEM or a Gelco-compatible heavy-duty collar, and reseal with fire-rated silicone.
• DuraFlex termination caps clog with creosote in low-draft, beach-adjacent installations. Pacific moisture plus lazy draft equals glazed buildup that factory screens can’t shed. We swap to a Gelco high-flow cap with wider mesh, or add an Olympia Chimney draft-inducer if the flue run is marginal. Either way, we clean what we can reach and show you the photos.

Our DuraFlex Chimney Repair Process

1. 1
   Call intake. A live person answers, notes your DuraFlex model if you know it, and schedules a window. We’ll be there when we say.
2. 2
   Level-2 camera inspection. Our tech runs a chimney camera, shoots photos of every DuraFlex joint, collar, and flex point, and delivers a plain-English verdict: what’s wrong, what caused it, what it costs.
3. 3
   Parts decision. If your DuraFlex SW needs a section, we check OEM availability against quality aftermarket from our Copperfield and Famco stock. We explain the trade-off, warranty implications, and price difference. You decide.
4. 4
   The repair. Background-checked, uniformed technicians complete the work with professional-grade materials. No builder-grade substitutes. Russell Haines trained our senior techs personally on DuraFlex splice techniques at the shop in Eagle Rock.
5. 5
   Post-repair test. We pressure-test or smoke-test every DuraFlex liner repair, depending on fuel type, and run the camera again to confirm the fix.
6. 6
   Documentation and guarantee. You get photos, the written report, and our 90-Day Done Right Promise. In writing, no arguing. If it’s not right, we come back.

We give you the number before we start. Call (844) 803-1545 for a free estimate - the number on the estimate is the number on the invoice.
