This page is for Bedford homeowners who already know they have a DuraFlex liner, cap, or component and need it repaired correctly. Maybe you’ve spotted spalling brick near the flue exit, or water staining on the ceiling below the chimney breast, or a cap that no longer seats flush after last winter’s ice. Call us at (914) 409-9387 - a live person answers, 24 hours a day.

How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW304 and SW316 flexible liners - the stainless workhorses we see in most Bedford pre-fab fireplace retrofits - develop creosote buildup at the flex points where the corrugations trap condensation. In Bedford’s freeze-thaw cycle, that trapped moisture accelerates metal fatigue at the elbows. We pull the liner, inspect each corrugation valley with a borescope, and replace individual sections rather than condemning the full run when the damage is localized. OEM DuraFlex sections mate cleanly with existing terminals.
• DuraFlex Pro rigid liners - common in the taller stone-and-timber colonials near Bedford Village with straight vertical runs - suffer mortar joint failure where the rigid sections meet the crown. The Pro’s tighter tolerances mean less forgiveness for crown settling. We repoint with matching high-temp mortar, reset the section with a proper load-bearing plate, and seal the crown with a vapor-permeable treatment that won’t trap moisture against the stainless.
• DuraFlex termination caps and wind-directional rain caps - the mesh on older Gelco-compatible caps (often paired with DuraFlex runs in 1990s Bedford builds) corrodes at the weld points where salt-laden air from the county’s winter road treatment settles. We stock replacement caps from Olympia Chimney and Famco that fit the DuraFlex collar spec without adapter kits, preserving draft performance.
• DuraFlex aluminum liners (the AL29-4C alloy series) - installed in some Bedford oil-to-gas conversions from the 2000s - pit at the condensate drain when flue gases drop below dew point. Aluminum can’t be patched to code; we replace with SW316 stainless, sized to the appliance’s actual BTU output, not the original overspec. This is one place where using the OEM DuraFlex part number matters for warranty transfer if you sell.
• DuraFlex Tee and wye connectors - the collection boot on Tee assemblies cracks where the cleanout door hinge fatigues from repeated thermal cycling. We’ve found that aftermarket Tee bodies from Copperfield fit the DuraFlex collar but use a thinner gauge steel at the weld seam. We use OEM DuraFlex Tees for this repair, even when the aftermarket part costs less, because the seam failure shows up three winters later and we’re not coming back for the same leak.

Our DuraFlex Chimney Repair Process

1. 1
   Call and schedule. A live person answers, asks what you’re seeing, and books a Level-2 camera inspection. We don’t diagnose over the phone.
2. 2
   Inspection and documentation. Our tech runs a camera the full flue length, photographs the failure point, and explains what you’re looking at in plain English. You get the photos.
3. 3
   Parts decision. We check DuraFlex OEM availability against quality aftermarket alternatives from HeatShield, Gelco, or our other brands. We tell you which we’re using and why.
4. 4
   Repair with test. We complete the repair, pressure-test or smoke-test as the job requires, and run the camera again to document the finished work.
5. 5
   Written guarantee. You get the 90-Day Done Right Promise in writing, the invoice matching the estimate, and our direct line if anything feels off.

What DuraFlex Chimney Repair Costs in Bedford

Most DuraFlex repairs in Bedford fall between these ranges:

What moves the price: height of the chimney run, accessibility (steep slate roofs common in Bedford add time), and whether we need to break into a wall to access a concealed Tee. We agree the full price before booking the repair. Estimates are free - call (914) 409-9387.

Why Bedford Homeowners Call Hearthstone Chimney Co. for DuraFlex Work

We’ve been servicing the stone-and-timber colonials and center-chimney Capes around Bedford Village, Bedford Hills, and Katonah for over 42 years. Russell Haines learned this trade at Los Angeles Trade-Technical College and has spent more than two decades inspecting flues in this county. He still fires up a woodstove in his garage every fall - not for the photo, just because he likes a clean burn.

Our techs carry DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield parts on the truck, so we’re not ordering and rescheduling. The 90-Day Done Right Promise means if it’s not right, we come back - in writing, no arguing. Most jobs finish in one visit. The price we quote is the price on the invoice.

If it needs doing, we will tell you. If it does not, we will tell you that too.
