How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW stainless liners: The 316Ti alloy handles Illinois freeze-thaw cycles well, but we’ve found the top collar seal degrades faster than the liner body in Downers Grove homes with no cap or a poorly fitted cap. Water pools at the exposed collar, accelerates crevice corrosion, and the liner pulls down slightly each season. We replace the collar with OEM-grade DuraFlex hardware or a compatible marine-grade stainless collar, then re-secure with a proper top plate and cap.
• DuraFlex AL aluminum liners: These lightweight liners are common in gas venting retrofits from the 2010s. The failure we see is not the aluminum itself but the slip joint connections working loose after years of thermal cycling. In Downers Grove’s clay-heavy soils, foundation settling adds lateral stress. We pull the liner, inspect each joint with a borescope, reseat with high-temp sealant, and add mechanical locking bands where the original friction fit has worn.
• DuraFlex relining tees and wyes: The tee body on DuraFlex 316Ti systems can crack at the weld seam when a wood stove has been over-fired repeatedly. The tee is the most expensive single fitting in the system. We evaluate whether the crack is superficial or structural using camera footage. If it’s through-wall, we source a replacement tee through our Haven buying network - DuraFlex OEM when lead times allow, or an Olympia Chimney equivalent that meets the same UL 1777 listing.
• DuraFlex top plates and storm collars: The stamped steel plates on older DuraFlex installations (pre-2015) rust through at the fastener holes first. Downers Grove’s combination of lake-effect humidity and road salt aerosol from I-88 and I-355 speeds this up. We replace with Gelco or Famco galvanized or stainless plates, sized to the existing flue, and seal with a proper storm collar and high-temp silicone - not roofing tar, which cracks in the first January cold snap.
• DuraFlex flex-to-rigid transitions: When a DuraFlex flexible liner terminates in a masonry chimney with a rigid flue extension, the transition sleeve is often the leak point. The original installer may have used generic HVAC tape or left a gap. We fabricate a custom transition from appropriate-gauge stainless or source a DuraFlex-specific adapter, then pressure-test the joint with a smoke pencil before we leave.

Our DuraFlex Chimney Repair Process

1. 1
   Schedule and scope: You call (331) 253-4980 and speak to a live person. We ask what you’re seeing, what appliance is vented, and when the DuraFlex product was installed if you know. We book a Level 2 inspection with camera scan.
2. 2
   Camera-scan inspection: Our tech runs a borescope the full length of the flue, records the footage, and inspects the exterior components - cap, crown, flashing, and top plate. Clause 4 of the Haven Standard requires this photo record on every job. The camera does not lie, and neither does the written price.
3. 3
   Written estimate: Before any repair begins, you receive a written scope, written price, and written warranty. If parts are needed, we specify OEM DuraFlex or the equivalent we intend to use, with the reason. No surprises.
4. 4
   Repair execution: Our background-checked, uniformed technician arrives with a text notification. We complete the repair using materials from our Haven buying network - DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, or Copperfield as the job requires.
5. 5
   Testing and documentation: We test draft, check for leaks with a smoke pencil or mirror, and provide you with the completed photo record and warranty documentation.
6. 6
   365-Day Done Right Promise: If anything isn’t right, we make it right. That’s stamped on every job under the Haven Standard.
