How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW (stainless wrap) liner systems develop cap separation at the termination collar after 8-12 years in Lansdale’s freeze-thaw cycle. The collar weld cracks where the cap flange meets the flue, letting water run straight down the wrap. We remove the damaged collar, inspect the wrap for interstitial corrosion the water caused, and install a DuraFlex-compatible Gelco or Famco cap with a stainless storm collar that sheds water past the termination point.
• DuraFlex Pro and DuraFlex 316Ti flexible liners use a factory crimp connection at the top plate that loosens when the cap gets knocked by ice shedding from steep Montgomery County roofs. The cap tilts, the crimp gaps, and smoke leaks into the attic through the chase cover. We reseat the liner with a proper top plate seal, then secure the replacement cap with through-bolts rather than friction fit - the camera doesn’t guess, and neither do we.
• DuraFlex relining jobs with undersized chase covers trap condensation between the cap and crown because the cover was cut for a clay flue, not a 6-inch or 8-inch flexible liner. The crown soaks up that moisture and spalls from the top down. We measure the chase opening, fabricate or source a properly sized cover from Copperfield or Olympia Chimney, and seal the crown with HeatShield CrownCoat where the masonry is still sound.
• DuraFlex 304-alloy caps on oil-flue installations in older Lansdale colonials near the Merrick Road corridor corrode from the inside out. Sulfuric condensate attacks the lesser alloy where the cap sits coolest - the underside of the lid and the mesh screen. We upgrade to 316-alloy or titanium-stabilized caps rated for oil and gas condensate, and we document the alloy stamp with a photo for your record.
• DuraFlex multi-flue caps with integrated dampers seize when creosote drips from the flue lip and bakes onto the damper hinge. The homeowner cranks the handle, bends the linkage, and now the cap won’t seal or open fully. We disassemble the cap on-site, ultrasonic-clean the hinge and linkage where possible, or replace the damper assembly with a Gelco equivalent that uses a sealed bushing instead of an exposed pin.

Our DuraFlex Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, checks DuraFlex part availability through our Haven network, and books your inspection. You get a text when your tech is en route.
2. 2
   NFPA 211 Level 2 camera inspection. We run the camera down the DuraFlex flue to the thimble, documenting liner condition, clearance to combustibles, and any water staining that points to cap or crown failure. You watch the feed in real time.
3. 3
   Written scope and price. Before any tool touches your chimney, you receive a written price, written scope, and written warranty - Haven Standard Clause 1. No verbal estimates, no surprises.
4. 4
   Parts decision: OEM or quality aftermarket. We stock DuraFlex-compatible caps, crowns, and storm collars from Gelco, Famco, and Olympia Chimney. If your warranty requires OEM, we source it. If not, we quote the aftermarket equivalent that meets or exceeds DuraFlex specs, and you choose.
5. 5
   Repair and test. We install, seal, and torque to spec. For crown work, we apply HeatShield CrownCoat or pour new concrete to NFPA 211 clearance standards. We run a smoke test or draft test to confirm the cap seals and the flue draws.
6. 6
   Documented record and cleanup. You get photos of the finished work, the camera footage from before and after, and a written warranty under our 365-Day Done Right Promise. Clause 4 of the Haven Standard requires we keep a copy too.

Why Lansdale Homeowners Call Level Two Chimney Lansdale for DuraFlex Work

We are independently owned and operated - not a franchise, not affiliated with DuraFlex - and we’ve inspected over 38,000 chimneys since 2009. Every DuraFlex job gets the same protocol: camera down the flue, written price before work starts, documented photo record when it’s done. Our technicians are background-checked, uniformed, and named to your appointment - not dispatched from a pool of unknown subs.

We also service HeatShield and Gelco systems, so if your DuraFlex installation has been modified or paired with another brand’s components, we don’t guess at compatibility. Our buying network sources materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield specifically to keep customer prices honest. The 365-Day Done Right Promise applies to every cap, crown, and seal we install. If it’s not right, we make it right.
