How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW 304 and 316 flexible liners: These show up in Bedford’s pre-1980s colonials where a full masonry rebuild is cost-prohibitive. We see creosote burn-through at the flex-to-rigid transition point, especially where the liner was pulled too tight through an offset flue. The fix is a custom-fabricated transition section with proper tension relief, not a patch.
• DuraFlex Pro series (heavy-wall flexible): Built for oil and gas, but Bedford’s shift back to wood and pellet has pushed some Pro liners beyond their design spec. Thermal cycling cracks the outer wall near the thimble connection. We sleeve with a DuraFlex Pro-compatible heavy-wall section or convert to a rigid DuraLiner system where the flue run allows.
• DuraFlex relining kits with factory-insulated wraps: The wrap settles over seasons, creating cold spots that accelerate creosote buildup in Bedford’s freeze-thaw climate. We remove the settled wrap, verify the air gap, and reinstall with stainless mesh spacers that maintain clearance for the life of the liner.
• DuraFlex tee and cleanout assemblies: The cast tee body outlasts the snout connection, but homeowners rarely know the snout is a separate part. We stock both OEM and aftermarket snouts; if the tee body is sound, we replace the snout alone and save the full assembly cost.
• DuraFlex rigid liner sections (DuraLiner): Used in straight Bedford chimneys, especially the newer construction near Bedford Hills. Joint separation from improper locking-tab engagement is the failure we find most. We reseat with proper tab engagement, add a locking-band backup, and pressure-test before we leave.

Our DuraFlex Chimney Liner & Rebuild Process

1. 1
   Call and schedule. A live person answers, books your Level-2 camera inspection, and sends a confirmation. We serve Bedford weekly, so wait times are short.
2. 2
   Inspection and documentation. Our technician runs a camera from firebox to cap, photographs every joint, offset, and transition. You see the footage. We deliver a plain-English verdict: what is wrong, what can wait, and what cannot.
3. 3
   Parts decision. If DuraFlex OEM is available and warranty-relevant, we use it. If the repair is out of warranty and a quality aftermarket part meets spec, we tell you both options and the price difference. No default to the most expensive.
4. 4
   The repair. Background-checked, uniformed techs complete most liner replacements and partial rebuilds in one visit. Full rebuilds are staged across two to three days with weather protection in place overnight.
5. 5
   Testing and sign-off. We smoke-test or pressure-test every liner installation per NFPA 211, review the photos with you, and leave the written report.
6. 6
   The guarantee. The 90-Day Done Right Promise is in writing before we start. If it is not right, we come back. No paperwork, no arguing.

What DuraFlex Chimney Liner & Rebuild Costs in Bedford

What moves the price: chimney height, number of flues, accessibility (steep Bedford roofs, tight property lines), and whether the existing liner can be extracted or must be demolished in place. We do not know your exact number until we inspect. Call (914) 409-9387 for a free estimate.
