How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW (stainless wall) liners with factory cap separation. The SW series uses a lighter-gauge cap attachment ring than competing lines, and after five to seven winters of Framingham’s freeze-thaw cycling, the mechanical joint between cap and flue can work loose. We find this most often on homes near Cushing Memorial Park where mature oaks drop heavy debris that accelerates cap fatigue. We replace with a heavier-gauge DuraFlex-compatible cap or, if the flue lip is still sound, a Gelco multi-flue cap with a deeper skirt.
• DuraFlex Pro oval liners with crown wash intrusion. The Pro oval’s low-profile termination sits close to the crown surface, so when the crown wash cracks, water tracks directly into the annular space rather than running off. In Framingham’s clay-heavy soils, that moisture wicks through the masonry and stains interior chimney breasts. We open the crown to the structural slab, re-pitch with a cricket if needed, and reset the Pro termination with a bead of high-temp sealant plus a vented rain cap.
• DuraFlex AL (aluminum) caps galvanically corroded on gas conversions. Homeowners who converted oil to gas in the 2015-2020 window often kept their original AL cap, but gas exhaust condensate is more acidic and attacks the aluminum faster than oil soot ever did. We see this on split-levels near Butterworth Park where those conversions clustered. We spec a 304 stainless replacement from our Haven buying network, sized to the existing DuraFlex AL flue diameter without disturbing the liner below.
• DuraFlex DW (double-wall) telescoping sections with crown settlement. The DW telescoping joint gives installers flexibility on height, but if the crown settles even half an inch, the telescoping section compresses and the cap tilts, creating a gap on one side. Squirrels in Framingham’s oak canopy find that gap fast. We jack the assembly to true vertical, re-bed the crown, and install a locking-band cap that tolerates minor future movement.
• DuraFlex relining jobs with aftermarket cap mismatch. A previous installer used a generic cap with a too-small collar on a DuraFlex 6-inch round liner; the cap blew off in a March nor’easter and the homeowner didn’t notice for weeks. Water entered, froze, and spalled the top course of brick. We document the flue dimensions with the camera, source the correct DuraFlex or Olympia Chimney cap through our network, and rebuild the top course if spalling is structural.

Our DuraFlex Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers, notes your DuraFlex product line if you know it, and books a Level 2 inspection with camera.
2. 2
   Camera-scan inspection. We run the camera down the flue to verify liner condition, then photograph the crown, cap, and surrounding masonry from the roof. Clause 4 of the Haven Standard requires this photo record on every job.
3. 3
   Written price and scope. Corrine Halstead or a named technician delivers a written price, written scope, and written warranty before any work starts. No exceptions.
4. 4
   Parts decision. We stock common DuraFlex caps and crowns, but if your series is older or uncommon, we source OEM or quality aftermarket through our Haven buying network, typically within 48 hours.
5. 5
   Repair and test. We complete the cap or crown work, run a smoke test or mirror check to verify draft, and photograph the finished condition.
6. 6
   Documentation and guarantee. You receive the photo record, the final invoice matching the written price, and the 365-Day Done Right Promise in writing.
