How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW (Stainless Wall) liners crack at the flex-to-rigid transition where the corrugated section meets the straight pipe above the smoke chamber. In West Hartford’s older colonials along Farmington Avenue, we’ve found these transitions fatigued after 15-20 winters of expansion and contraction. We cut back to sound metal, install a factory-compatible rigid section, and seal with high-temp silicone rated to 1,800°F - not generic furnace cement that’ll crumble by February.
• DuraFlex 316Ti liners suffer creosote bridging at the corrugation valleys when homeowners burn unseasoned oak or maple, which is common in neighborhoods near West Hartford Reservoir where folks stockpile free wood. The ridges trap glaze creosote that standard brushes skip. We rotary-clean with a custom whiptip head, then camera-inspect every valley before declaring the flue safe - no guesswork, no “it looks fine from down here.”
• DuraFlex Pro cap bases corrode at the mounting flange because the stamped steel flange sits in a mortar bed that stays damp from October through April in this climate. Water wicks behind the base, rust spreads under the paint, and suddenly you’ve got a cap lifting in a March wind. We pull the base, grind to clean masonry, and reset with a sloped mortar bed and weep channel so water exits instead of pools.
• DuraFlex relining collars loosen in high-heat fireplaces where the original installer used standard fasteners instead of the expansion-rated hardware DuraFlex specifies for hearth-mounted installations. The collar backs away, smoke leaks into the chase, and you smell it on the second floor. We reseat with proper fasteners and a refractory gasket - OEM spec, not hardware-store bolts that’ll walk loose again.
• DuraFlex chase covers delaminate at the drip edge when the galvanized underlayer separates from the painted topcoat after years of road-salt spray off I-84 and the Wilbur Cross Parkway. The cover looks intact from the ground, but water’s already getting to the framing. We document the delamination with camera photos you can see, then replace with a properly spec’d cover or a Copperfield stainless alternative if the chase geometry demands it.

Our DuraFlex Chimney Repair Process

1. 1
   You call, a live person answers. We ask what you’re seeing, what you’ve got for a fireplace or appliance, and whether you know the DuraFlex model. If you don’t, we’ll figure it out on site - no homework required.
2. 2
   Level-2 camera inspection with photo documentation. Our technician runs a camera the full flue length, photographs every joint, transition, and termination. You get the photos and a plain-English verdict: what’s wrong, what caused it, what happens if you wait.
3. 3
   Parts decision: OEM DuraFlex or quality aftermarket. If DuraFlex OEM is available and cost-competitive, we quote it. If lead time’s three weeks or the part’s discontinued, we source from Olympia Chimney or Famco with equivalent specs - never builder-grade substitutes that void what warranty remains.
4. 4
   The repair, done right the first time. Our crew arrives background-checked and uniformed, works methodically, and cleans behind themselves. Russell Haines still sketches flue diagrams in a pocket notepad before complex jobs - a habit from his trade-school days that keeps the crew aligned.
5. 5
   Post-repair test and documentation. We run the camera again, verify draft with a manometer, and show you the after photos. The 90-Day Done Right Promise goes in writing before we leave - if it’s not right, we come back, no paperwork, no arguing.
6. 6
   Cleanup and honest next-steps. We tell you when to sweep next, what to watch for, and whether any other issue can safely wait. No scare tactics. A chimney that’s sound for two more seasons gets that verdict.
