How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW304 and SW316 flexible liners: The seam welds on these stainless liners can open at stress points where the chimney shifts, which happens more than you’d think in the older colonials up near Huntington Center with their freeze-thaw cycles. We sleeve the damaged section with matching-gauge DuraFlex or, if the breach is isolated, cut and re-ferrule with OEM-grade couplings. We never patch with generic flex - the wall thickness and alloy spec must match or the warranty is voided.
• DuraFlex Pro smooth-wall liners: The Pro’s tight corrugations can trap acidic condensation in low-drafting chimneys, especially in Shelton’s damp shoulder seasons when homeowners burn intermittently. We pull a camera first to map the corrosion pattern, then either spot-reline the affected section or recommend a full Pro replacement if the wall thinning exceeds 20 percent. The call depends on what the photos show, not what we’d prefer to sell.
• DuraFlex DSA aluminum downspout adapters and termination caps: These components fatigue at the crimp joints after seven to ten years of thermal cycling. The symptom is water staining on the masonry below, often misdiagnosed as crown failure. We stock DuraFlex-compatible caps and adapters in our Shelton warehouse, so we’re not waiting on freight while your chimney leaks through another rain.
• DuraFlex rigid relining pipe (RPL series): The RPL’s gasketed joints can weep smoke at the collar if the original installer didn’t seat them against a clean square cut. We’ve found this on three jobs in the White Hills area where a previous contractor rushed the transition. We disassemble to the sound joint, re-cut square, and re-seat with fresh gaskets - done right, not caulked over.
• DuraFlex crown seal and waterproofing systems: DuraFlex’s water-based sealant performs well when applied to properly prepared masonry, but we’ve seen it fail prematurely over spalling brick that was never addressed underneath. We grind out the spall, repoint with matching mortar, let it cure, then apply the sealant to sound substrate. A sealant on rotten brick is money thrown away, and we don’t do that.

Our DuraFlex Chimney Repair Process

1. 1
   Call and schedule. A live person answers at (475) 265-6822, 24/7. We book a window that works, and we’ll be there when we say.
2. 2
   Level-2 camera inspection. Our technician runs a chimney camera from top to bottom, photographing every joint, course, and transition. You see the photos. We explain what they mean in plain English - no jargon, no scare tactics.
3. 3
   Parts decision. If the repair needs DuraFlex OEM components, we source them direct. If a quality aftermarket alternative from Olympia Chimney or Famco meets the spec and saves you money without cutting corners, we say so. As an independent DuraFlex service provider, we’re not bound to factory parts when better value exists.
4. 4
   The repair. Our background-checked, uniformed technician completes most DuraFlex repairs in a single visit. Mortar is mixed to the original lime-to-portland ratio for color match. Flashing is cut and folded on-site, not ordered from a catalog that almost fits.
5. 5
   Test and document. We pressure-test liner joints where applicable, verify draft with a manometer, and re-run the camera on jobs where access allows. You get a photo report and a written verdict.
6. 6
   The guarantee. Every repair is covered by our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back. That’s the Keystone Standard.

We give you the exact number before we start - a square deal, no surprises on the bill. Call (475) 265-6822 for a free estimate.
