How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW (Stainless Wall) liners develop seam separation near the smoke chamber elbow. The single-wall flex sections take the most stress where the flue turns from vertical to sloped, especially in Fort Worth’s clay-heavy soils where foundation shift puts lateral pressure on the chimney stack. We cut back to sound metal, sleeve with DuraFlex SW replacement sections or transition to DuraFlex DW (double-wall) at the stress point if clearances allow.
• DuraFlex DW liners show outer wall corrosion from condensate trapping in capped-off flues. Fort Worth humidity spikes in spring and fall; when a fireplace sits idle with a top-sealing damper or poorly vented cap, acidic condensate pools between the walls. We pull the damaged section, verify the inner liner integrity with a borescope, and replace only what’s necessary - never the full run if the upper flue is sound.
• DuraFlex AL (aluminum) liners in gas applications suffer draft hood corrosion above 90% efficiency furnaces. The AL series isn’t rated for the cooler exhaust temperatures of high-efficiency gas units; condensate runs back down and eats the collar. We replace with DuraFlex SW stainless or, if the appliance allows, switch to an approved B-vent system and document the change for your HVAC warranty.
• DuraFlex Pro liners lose insulation compression at termination, creating cold spots that accelerate creosote buildup. The Pro’s wrap-and-foil insulation system settles over time, especially where Fort Worth’s summer heat cycles the metal. We re-insulate with OEM compression sleeves or, if the gap is localized, use HeatShield Cerfractory Foam to restore the thermal barrier without a full pull.
• DuraFlex tee connections crack at the cleanout door weld. The tee body is cast, but the cleanout door plate is stamped and spot-welded; thermal cycling opens the seam. We source DuraFlex OEM replacement tees or, when lead times stretch, fabricate a compatible tee from Olympia Chimney components that mates to existing DuraFlex liner - always with your written approval and warranty disclosure.

Our DuraFlex Chimney Liner & Rebuild Process

1. 1
   Camera-scan diagnosis. Corrine Halstead or a named technician runs an NFPA 211 Level 2 inspection with a self-leveling camera down the full flue length. You see the footage in real time; we timestamp every finding.
2. 2
   Written scope and price. Before we leave, you get a single-page document: what we found, what we recommend, what it costs, and what the warranty covers. Clause 1 of the Haven Standard - have it in writing.
3. 3
   Parts decision with full disclosure. We quote DuraFlex OEM first, then show equivalent aftermarket options from our buying network (Olympia Chimney, Famco, Copperfield) if availability or price matters. You choose; we document.
4. 4
   Installation or rebuild. Liner jobs get a pull-and-replace with new insulation and termination hardware. Rebuilds get staged demolition, structural assessment, and masonry reconstruction with the liner installed in the new flue.
5. 5
   Post-work verification. We camera the completed job, perform a smoke or pressure test per application, and add the photos to your documented record. Clause 4 of the Haven Standard requires it.
6. 6
   Cleanup and written warranty. We haul debris, protect your floors with the same care on the way out, and leave you with a stamped warranty card and the 365-Day Done Right Promise.

Why Fort Worth Homeowners Call Level Two Chimney Fort Worth for DuraFlex Work

We’ve inspected over 38,000 chimneys since 2009, and a healthy share of those runs were DuraFlex - enough that our crews know the difference between a Pro series insulation settlement and a DW outer-wall failure without pulling the whole liner to find out. The camera doesn’t lie - and neither does the written estimate. Every DuraFlex job gets the same documentation standard: photos, measurements, and a price on paper before anyone asks. If we recommend a full rebuild over a liner swap, you’ll see the spalling brick or compromised structural course that justifies it. Our 365-Day Done Right Promise covers every liner and rebuild we touch, and our Free Second Opinion policy means you can bring us any competitor’s written quote for an honest read. We also carry HeatShield and Gelco materials, so if your DuraFlex liner is sound but the surrounding masonry needs help, we don’t force a brand mismatch to solve it.
