How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW (stainless steel flex liner) - crevice corrosion at the collar weld. The SW series uses a 316Ti stainless collar joint that’s vulnerable to chloride attack when condensation pools in low spots. In Fort Worth, we see this accelerate after ice events like the 2021 freeze, when thermal cycling opens micro-fissures. We cut back to sound metal, install a DuraFlex OEM collar or a Haven-spec 316L replacement with full-penetration welds, and camera-verify the repair.
• DuraFlex AL (aluminum flex liner) - flue gas spillage from liner collapse. The AL series is rated for gas appliances only, but we find it retrofitted into wood-burning systems in Ridglea and Berkeley Place homes from the 2015-2019 flip boom. Heat distortion causes the aluminum to sag and separate at the tee. We remove the AL liner entirely, replace with a DuraFlex SW or a HeatShield Cerfractory foam application where the flue geometry allows, and document the appliance match with photos.
• DuraFlex Pro - mortar degradation in the vented wall cavity. The Pro’s vented double-wall design relies on airway channels that clog with Fort Worth’s fine limestone dust and pollen load. Moisture trapped behind the wall leads to spalling on the exterior chimney face. We rebuild the affected courses with matching brick, install a Gelco or Famco cap with proper mesh spacing, and seal with a vapor-permeable waterproofing agent.
• DuraFlex DSA (direct-vent appliance connector) - condensate line blockage. The DSA’s condensate drain port is 3/8-inch and prone to plugging with scale in Fort Worth’s hard-water zones, particularly west of I-35 near Lake Worth. Backpressure corrodes the appliance connector from the inside. We rod and flush the drain, replace the DSA if wall thickness is below 0.012 inch per our caliper reading, and pitch the replacement per manufacturer spec.
• DuraFlex termination caps - wind-driven rain infiltration. The standard DuraFlex rain cap uses a snap-fit base that loosens after repeated thermal cycling. In Fort Worth’s spring storm season, we find water tracks running down the flue and staining the smoke chamber. We replace with a Gelco or Olympia Chimney locking-band cap, or a custom Cricket-style fabricated cap for oversized flues, and photo-document the seal.

Our DuraFlex Chimney Repair Process

1. 1
   Call and schedule. A live person answers. We book your NFPA 211 Level 2 inspection, assign a named technician, and text you when they’re en route.
2. 2
   Camera-scan inspection. We run a chimney camera the full flue length, inspect the exterior crown, flashing, and brick courses, and record every finding. Clause 4 of the Haven Standard requires this photo record on every job.
3. 3
   Written price and scope. Corrine Halstead reviews the findings, sources DuraFlex or compatible parts through our Haven buying network, and delivers a written price, written scope, and written warranty before any work begins. The camera doesn’t lie - and neither does the written estimate.
4. 4
   Repair with OEM or quality aftermarket parts. We use DuraFlex components where they make sense, HeatShield Cerfractory foam for resurfacing, Gelco or Famco caps, and Olympia Chimney or Copperfield fittings where geometry or availability favors them. Every part is logged in your job record.
5. 5
   Post-repair test and documentation. We run a smoke test or draft measurement, verify clearances, and add completion photos to your documented record. You get the full file by email.
6. 6
   365-Day Done Right Promise. If it’s not done right, we make it right. That’s stamped on every job under the Haven Standard.
