How DuraFlex Products Fail - and How We Fix Them

• DuraFlex SW gas venting: corroded termination caps from coastal salt air. Hicksville sits close enough to the Sound that salt-laden air accelerates cap corrosion on DuraFlex SW terminations, especially on two-story colonials with exposed rooflines. The cap degrades, moisture enters, and the galvanized inner liner begins spotting. We replace with OEM DuraFlex caps or marine-grade equivalents and reseal with high-temp silicone rated for the SW’s operating range.
• DuraFlex AL aluminum liner: creosote bridging in wood-burning conversions. The AL series runs cooler than stainless, which sounds efficient until creosote bridges across the corrugations in Hicksville’s freeze-thaw cycles. We’ve pulled solid plugs of it from AL liners in Levittown-adjacent ranches where owners burned unseasoned oak. We mechanical-brush the liner, run a camera to confirm clearance, and document the before-and-after for the homeowner’s file.
• DuraFlex SS stainless liner: weld-seam separation at offset elbows. The SS series handles heat well, but factory weld seams at offset elbows can work loose after a decade of thermal cycling, particularly in fireplaces converted from wood to high-BTU gas inserts. We spot this with camera inspection, cut out the failed section, and replace with a DuraFlex OEM offset or a custom-fabbed equivalent if the original spec is discontinued.
• DuraFlex Pellet venting: auger-feed misalignment causing back-venting. Pellet systems demand precise venting alignment, and DuraFlex pellet pipe that’s been homeowner-adjusted or bumped during cleaning often drifts out of spec. We see this in Hicksville split-levels where the vent run is long and horizontal. We realign to DuraFlex’s published slope requirements, replace any crushed termination sections, and test draft pressure with a manometer.
• DuraFlex twin-wall factory-built chimney: joint gasket hardening. The compressed fiber gaskets between twin-wall sections harden after 15-20 years, especially in Hicksville’s summer humidity swings. Combustion gases leak at the joints, staining the chase cover. We replace gaskets with DuraFlex-compatible high-temp rope, re-torque the locking bands to spec, and pressure-test the assembly.

Our DuraFlex Fireplace Services Process

1. 1
   Call intake with a live person. We ask what you’re seeing, what you’ve burned or run, and when the system last worked properly. No phone trees. If it’s urgent, we flag it.
2. 2
   Level-2 camera inspection on arrival. Our technician runs a chimney camera before touching tools. You see the footage. We explain what we’re looking at in plain English, point to the DuraFlex component involved, and identify whether it’s an OEM part or an aftermarket equivalent already in place.
3. 3
   Parts decision with upfront pricing. If the repair needs a DuraFlex OEM component, we quote it. If a quality aftermarket part from our HeatShield or Gelco inventory meets or exceeds the spec at lower cost, we say so plainly. The estimate number is the invoice number.
4. 4
   Repair with documentation. We complete most DuraFlex fireplace repairs in one visit. The technician photographs the finished work, tests operation under load, and records draft readings or gas pressures as applicable.
5. 5
   Written guarantee and cleanup. You receive the 90-Day Done Right Promise in writing before we leave. We haul away old parts. The fireplace is ready to use.

What DuraFlex Fireplace Services Costs in Hicksville

What moves the price: accessibility of the chimney chase, whether the DuraFlex component is still in production, and whether previous work used OEM or mismatched parts that require rework. We do not recommend work without camera evidence you can see for yourself. Call (516) 259-3797 for an exact quote - estimates are free.
