How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW 304/316 factory caps warp at the mesh skirt where the stainless meets the flue tile in Shelton’s freeze-thaw cycles. The factory spot-weld holds moisture, expands, and the mesh pulls away from the frame. We see this most on the 8″ and 10″ round models. We replace with a Gelco or Famco multi-flue cap with a wider skirt and mechanical fastening - no welding to fail again.
• DuraFlex Pro 1.5″ oval liners push condensation upward when the cap lacks adequate internal clearance. The Pro’s tighter wrap traps more moisture than standard round liners, and a shallow cap turns that moisture into accelerated crown spalling. We spec caps with 4″ minimum internal height and add a crown coat with Copperfield CrownSeal when the concrete is still structurally sound.
• DuraFlex 316Ti chimney caps lose their spark arrestor mesh to creosote corrosion if the homeowner burns unseasoned oak, which is common in Shelton with local cordwood. The titanium stabilizer resists acid but not the physical clogging that causes backpressure and mesh blowout. We pull the cap, document the flue condition with camera, and install a cleanout-friendly cap with removable mesh for future maintenance.
• DuraFlex factory chase covers on manufactured chimneys - the stamped steel units shipped with some 6″ and 8″ kits - rust through at the diverter bend in 7-10 years in Fairfield County humidity. We do not re-order these. We measure on-site and fabricate a Copperfield or Olympia Chimney .032 aluminum or stainless chase cover with cross-break diverter and proper storm collar.
• DuraFlex DVL double-wall caps separate at the inner/outer wall joint when the crown beneath them settles or the flue shifts. The cap itself is fine; the gap beneath it lets water run straight down the air channel. We re-seat with a proper flue-top seal, level the crown with HeatShield CrownCoat if the damage is under 1/4″, or pour a new crown when the structural integrity is gone.

Our DuraFlex Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers 24/7. We ask the DuraFlex model or liner size if you know it, and what symptoms you’re seeing - water, draft issues, debris, or visible damage.
2. 2
   Level-2 camera inspection on arrival. Our tech runs a camera the full length of your DuraFlex liner, photographs the cap and crown from the roof, and shows you the footage. No recommendations without evidence you can see.
3. 3
   Parts decision: OEM vs. quality aftermarket. We stock DuraFlex-compatible caps and crowns from Gelco, Famco, Olympia Chimney, and Copperfield. If your warranty is active and requires OEM, we source it. If not, we recommend the better-built aftermarket equivalent and explain why.
4. 4
   The repair. Background-checked, uniformed technicians complete most jobs in a single visit. Crown work gets hand-troweled the old way when the geometry demands it. Cap installs get torque-checked and sealed.
5. 5
   Post-repair test and documentation. We run the camera again, verify draft and clearance, and leave you with photos, a plain-English verdict, and your 90-Day Done Right Promise in writing.
6. 6
   Cleanup and close. We haul away old material. The number on your estimate is the number on your invoice. No surprises.

Why Shelton Homeowners Call Hearthstone Chimney Co. for DuraFlex Work

We have been sweeping and repairing chimneys in Shelton since 1984. Russell Haines learned this trade at Los Angeles Trade-Technical College, then spent two decades running brushes through the older colonials up near Huntington Center - the ones that throw every problem at you at once. He knows a DuraFlex system from a generic import, and he knows when a crown can be coated versus when it needs to come out.

Our 90-Day Done Right Promise is in writing, no arguing. If it is not right, we come back. Calls are answered by a live person, 24 hours a day, every day. Our technicians are background-checked and uniformed, and most jobs finish in a single visit. We also service HeatShield and Gelco systems, so if your DuraFlex job reveals a liner or smoke chamber issue, we handle it without calling in another contractor. That is how we have operated for over 42 years, and how we plan to operate for the next 30.
