How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW304 and SW316 flexible liners: seam separation at the tee connection. These corrugated stainless liners expand and contract with every burn cycle. In West Chester’s freeze-thaw climate, the tee body takes stress at the seam weld where the horizontal snout meets the vertical riser. We’ve pulled separated tees in homes off High Street where the homeowner smelled smoke in the attic for weeks before calling. We cut back to sound metal, install a new DuraFlex tee with an extended snout where clearance allows, or transition to a rigid tee if the offset demands it.
• DuraFlex Pro: premature corrosion at the cap and top plate. The Pro line’s lighter-gauge alloy saves cost upfront but weathers faster when caps are missing or undersized. Rain enters, pools at the top plate, and the crevice between liner and plate becomes a rust cell. We replace the top plate with a heavier-gauge DuraFlex or Gelco equivalent, seal with high-temp silicone rated to 600°F, and upsize the cap if the flue opening is within two inches of the crown edge.
• DuraFlex relining of unlined brick chimneys: mortar joint voids visible on camera. When a DuraFlex liner is dropped into a 1920s West Chester colonial with eroded mortar, the liner can chafe against sharp brick edges. Over seasons this abrades the outer wall, especially on the offset where the liner bends to meet the thimble. We spot the abrasion on camera, pull the liner, parge the smoke chamber smooth with HeatShield, and reinstall with proper spacers so the liner centers in the flue.
• DuraFlex ovalizer kits in tight flues: oval collapse or re-rounding. Some West Chester row homes on Matlack Street have 6.5-inch round flues that won’t accept a standard round liner. The ovalizer compresses the liner into an oval, but if the compression is uneven or the support wires fatigue, the liner re-rounds in the flue and jams. We measure the flue with a laser bore gauge before quoting, and if ovalization is needed, we source factory-ovalized DuraFlex sections rather than field-ovalizing, which carries a cleaner warranty path.
• DuraFlex tee and snout assemblies: snout sag in long horizontal runs. In West Chester homes with exterior chimney breasts, the horizontal snout can droop if the support bracket was omitted or fastened to compromised masonry. The sag creates a creosote pocket and restricts draft. We install a stainless support bracket anchored to structural framing, not just the facing brick, and sleeve the snout with a rigid section where the run exceeds 18 inches.

Our DuraFlex Chimney Liner & Rebuild Process

1. 1
   Camera-scan inspection. We run a chimney camera the full length of the flue, per NFPA 211 Level 2. You see what we see. Corrine’s rule: the camera doesn’t negotiate, it just shows you what’s there.
2. 2
   Written scope and price. We deliver a written price, written scope, and written warranty before any work starts. Haven Standard Clause 1. No verbal quotes, no surprises.
3. 3
   Parts decision: OEM DuraFlex or quality equivalent. We source DuraFlex direct when the job calls for matching an existing system under warranty scrutiny. When the existing liner is out of warranty and the flue geometry allows, we may propose Gelco or Olympia Chimney equivalents through our Haven buying network, with the trade-off explained in writing.
4. 4
   Installation or rebuild. Liner replacements are pulled and installed same-day in most cases. Partial rebuilds (crown, top courses, flue wall) take two to three days. Full rebuilds are staged with a temporary cap to keep water out between masonry and liner work.
5. 5
   Smoke test and draft measurement. We run a smoke pellet test and measure draft with a digital manometer. Readings are recorded and included in your photo documentation.
6. 6
   Cleanup, documentation, and warranty registration. Clause 4 of the Haven Standard requires a documented photo record on every job. You receive the full archive, plus your 365-Day Done Right Promise in writing.
