This page is for Elmhurst homeowners who’ve identified DuraFlex components in their chimney system, whether that’s a DuraFlex Pro liner, a DuraFlex SW stainless flex, or a DuraFlex HT relining kit installed during a prior repair. Corrine Halstead and our crew have worked these products across Elmhurst for years, including the older bungalows near York Woods where freeze-thaw cycling hits harder than the manufacturer specs suggest.

How DuraFlex Products Fail - and How We Fix Them

• DuraFlex Pro liner: crevice corrosion at the collar weld. The Pro’s 316Ti stainless collar joint sits right in the condensation zone of mid-efficiency furnaces common in Elmhurst’s 1950s-1970s housing stock. We see pinholing here that a flashlight inspection misses entirely. Our fix: camera-locate the breach, cut back to sound metal, and splice in a DuraFlex Pro OEM collar or a compatible 316Ti section from Olympia Chimney’s catalog if lead times stretch.
• DuraFlex SW (smooth wall): seam separation in offset installations. The SW’s interlocked seam can work open when previous installers routed around tight Elmhurst chimney throats without proper support spacing. The gap vents flue gases into the masonry cavity. We pull the damaged section, re-run with proper DuraFlex support components or transition to HeatShield Cerfractory foam if the offset is too severe for safe flex routing.
• DuraFlex HT: thermal blanket compression in tall flues. The HT’s insulating blanket settles in vertical runs over 25 feet, which describes a fair number of Elmhurst’s two-story-plus-basement homes. The top third loses protection, and the liner overheats. We measure blanket density with a borescope, then either re-insulate with DuraFlex OEM blanket or spec a Gelco high-temperature wrap if the original specification is discontinued.
• DuraFlex Pro to masonry transition: spalling brick at the thimble. DuraFlex’s thimble plates are well-made, but the masonry around them in Elmhurst’s clay-rich soil zone takes on water, freezes, and pushes the plate out of square. We repoint with Type N mortar matched to local brick hardness, reset the thimble, and seal with a proper crown wash, not silicone.
• DuraFlex cap and storm collar: galvanic corrosion at the clamp. When DuraFlex caps meet aluminum storm collars in Elmhurst’s road-salt air, the galvanic reaction seizes the clamp and tears the collar in wind. We replace with stainless-to-stainless mating, source the cap through Famco if DuraFlex lead times run long, and document the materials change in your written warranty.

Our DuraFlex Chimney Repair Process

1. 1
   Call and schedule. A live person answers. We ask the DuraFlex model or series if you know it, the appliance type, and the symptom. We book a Level 2 inspection with camera.
2. 2
   Inspection and documentation. Corrine or a uniformed, background-checked tech runs the camera the full flue length. We record liner condition, seam integrity, collar weld status, and masonry interaction points. The camera doesn’t editorialize. Neither do I.
3. 3
   Written estimate with parts decision. You get a written price, written scope, and written warranty before any work starts. We note whether we’re using DuraFlex OEM parts or quality aftermarket equivalents from our Haven buying network, and why.
4. 4
   Repair and real-time verification. We perform the repair, then camera-verify the result. Smoke test or draft reading follows, depending on the appliance.
5. 5
   Photo record and warranty delivery. Clause 4 of the Haven Standard requires a documented photo record on every job. You get your copy; we keep ours on file. The 365-Day Done Right Promise is stamped and active.
6. 6
   Cleanup and follow-up. We leave the work area as found. A text confirms completion. Your written warranty and photo record are in hand before we leave.
