How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW (Stainless Wall) liners develop creosote bridging at the flex joints. The corrugations that make this line flexible also create ledges where glazed creosote builds up, especially in Jersey City’s older homes with slower-burning fireplaces. We remove the buildup with rotary whipping and, if the liner wall is still sound, reinstall with a proper top-sealing damper to improve draft velocity and reduce future accumulation.
• DuraFlex Pro liners show premature weld-seam separation near the top of the flue. This line’s lighter-gauge construction saves on material cost but can fatigue where the chimney transitions from interior masonry to exterior exposure, particularly after freeze-thaw cycles in Hudson County winters. We cut back to sound metal and splice in a matching DuraFlex Pro section, or upgrade to DuraFlex SW if the homeowner burns frequently.
• DuraFlex AL (Aluminum) liners corrode from the inside out when used with gas appliances. Aluminum is rated only for certain gas venting applications, yet we find it misinstalled in Jersey City condo conversions where a previous owner swapped wood for gas without updating the liner. The fix is full replacement with a stainless DuraFlex liner rated for the appliance - no exceptions, no patches.
• DuraFlex relining kits with factory-insulated jackets settle and create gaps at elbows. The insulation compresses over time in tall Jersey City brownstone flues, especially where offsets angle around original structural members. We remove the settled jacket, re-insulate with fresh Ceramic Blanket to OEM spec, and re-secure with stainless mesh and refractory sealant.
• DuraFlex termination caps clog with mortar debris from deteriorating crowns. In Paulus Hook and the Heights, we’ve pulled caps packed solid with sand and broken crown pieces that backed up exhaust into the home. We clear the cap, inspect the crown with our camera, and rebuild the crown with proper slope and drip edge so the liner can breathe again.

Our DuraFlex Chimney Liner & Rebuild Process

1. 1
   Call and schedule. A live person answers (732) 507-9649, 24/7. We book a Level-2 inspection with camera, not a sales visit.
2. 2
   Camera inspection and documentation. Our technician runs a 360-degree camera the full length of your DuraFlex liner, captures photos of every defect, and explains what we’re seeing in plain English before any work is discussed.
3. 3
   Parts decision: OEM DuraFlex or quality aftermarket. We stock common DuraFlex diameters and lengths. If your job needs a custom size or faster turnaround, we’ll source equivalent-grade stainless from Olympia Chimney or Gelco - always disclosed, never substituted without your okay.
4. 4
   The repair or rebuild. Background-checked, uniformed technicians complete most DuraFlex liner replacements and partial rebuilds in one visit. Full rebuilds needing masonry cure time may require a second trip.
5. 5
   Post-repair combustion test. We verify draft, check for leakage at joints, and confirm proper appliance connection before we pack up.
6. 6
   Written guarantee and cleanup. You get the 90-Day Done Right Promise in writing - if it’s not right, we come back until it is. No arguing, no paperwork chase.
