How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW (stainless wrap) liners: weld-seam separation at the flex points. The SW series uses a corrugated 316Ti stainless core with an outer wrap. In Elmhurst, where freeze-thaw cycles run from late October through April, the expansion gap at the top flex joint can work the seam open after eight to twelve years. We cut back to sound metal, install a DuraFlex OEM top adapter with a reinforced collar, and pressure-test before we leave. If the separation runs below the smoke chamber, we sleeve with new DuraFlex SW or transition to a rigid Olympia Chimney liner depending on flue geometry.
• DuraFlex AL (aluminum) liners: premature corrosion in gas-venting applications with marginal draft. The AL series is rated for Category I gas appliances only, but we see them in Elmhurst bungalows near York Woods where the furnace was upgraded to a higher-efficiency unit without relining. The cooler exhaust condenses; the aluminum oxidizes from the inside out. We document the corrosion class with the camera, quote a 316Ti stainless replacement, and note in writing whether your appliance category has changed.
• DuraFlex Pro: insulation compression at offsets. The Pro line ships with a ceramic blanket that maintains flue-gas temperature. On Elmhurst’s older masonry chimneys with baked-in offsets, the insulation compresses at the bend and creates a cold spot. We find this with a laser temperature reading during the camera scan. The fix is either a custom-cut rigid section through the offset or a DuraFlex Pro re-insulation with denser wrap at the bend point.
• DuraFlex tee connections: snout cracking at the cleanout base. The tee snout on older DuraFlex installations takes the brunt of condensation and soot loading. In homes where the cleanout was never opened, acidic buildup eats the weld. We replace with a current-spec DuraFlex tee or, if the flue is ovalized, fabricate a transition from Famco components. Either way, you get a photo of the old tee and the new one in place.
• DuraFlex termination caps: wind-driven rain infiltration through corroded mesh. Elmhurst sits in a direct west-east wind corridor off the prairie. DuraFlex caps with standard 3/4-inch mesh clog with cottonwood seed in June and corrode through by year six. We upgrade to a Gelco stainless cap with 5/8-inch mesh and a drip edge, or a Copperfield custom cap if the crown is irregular. The camera doesn’t editorialize. Neither do I. We show you the rust streak on the flue wall and quote the cap separately from any liner work.

Our DuraFlex Chimney Liner & Rebuild Process

1. 1
   Camera-scan inspection (NFPA 211 Level 2). Corrine Halstead or a named, background-checked technician drops a self-leveling camera the full flue length. You watch live if you’re home, or we text a link to the footage within two hours. Every frame is archived under Haven Standard Clause 4, a practice we started in 2009.
2. 2
   Written scope and price. We deliver a single-page document: what we found, what we recommend, what it costs, and what we warranty. No verbal quotes. No “we’ll see once we start.” Clause 1 of the Haven Standard requires the price in writing before work begins.
3. 3
   Parts decision: OEM DuraFlex or quality aftermarket. If your flue geometry matches a standard DuraFlex catalog part, we quote OEM. If you need a custom transition, fabricated offset, or faster turnaround, we quote HeatShield, Gelco, or Olympia Chimney equivalents from Haven’s buying network. We note the warranty difference in writing.
4. 4
   Installation or rebuild. Liner pulls are done with a controlled descent rig, not gravity drops. Full rebuilds follow a staged schedule: tear-down, structural assessment, re-lay with matching brick where possible, liner set, and cap installation. You get a text when the crew is en route.
5. 5
   Pressure test or smoke test, photo record, and written warranty. Gas liners get a pressure test to 1.5 inches water column. Wood-burning liners get a smoke-pencil draft check. We photograph every critical joint, stamp the 365-Day Done Right Promise on your invoice, and file a copy. If you have a competitor’s written estimate, we offer a Free Second Opinion.
6. 6
   Cleanup and documentation. The crew vacuums the work area with HEPA filtration and leaves your written warranty, photo link, and our direct line. Live phone support runs 24/7 if you have questions after we leave.
