How DuraFlex Products Fail - and How We Fix Them

• DuraFlex Pro stainless liners: The 316Ti alloy handles Paterson’s freeze-thaw cycles well, but we’ve seen the Pro’s upper termination plates corrode prematurely where the stack sits above a vented attic in Eastside homes. Moisture gets trapped between the plate and the flue tile, and the galvanized hardware starts weeping rust down the brick. We replace with marine-grade fasteners and a copper or stainless termination cap from Olympia Chimney, not the original hardware, and we seal the gap with a proper storm collar.
• DuraFlex Elite double-wall liners: The Elite’s interlocked seam construction is solid until a chimney fire or long-neglected creosote buildup forces expansion at the seam joints. In the older homes around Garrett Mountain, we find Elite liners where the inner wall has bellied inward at a seam, restricting draft without fully collapsing. We camera every Elite job to locate the exact seam, then sleeve the damaged section or replace the run if the deformation exceeds manufacturer tolerance.
• DuraFlex DW (double-wall) factory-built chimney sections: The DW’s twist-lock joints can work loose after years of thermal cycling, especially on exterior chimneys exposed to Paterson’s northwest wind. We find the telltale soot staining at the joint, disassemble to the sound section, and reseat with fresh locking tabs. If the female socket has ovalized, we source a replacement section rather than forcing a leak-prone fit.
• DuraFlex flexible relining for oil or gas: The flexible aluminum and stainless products settle into offsets over time, creating low spots where condensate pools. In Paterson’s converted two-family homes, we see this where a original masonry chimney was never meant for a modern appliance. We pull the liner, check for pitch with a laser level, and reinstall with proper support spacing so the condensate drains back to the appliance or a collection tee.
• DuraFlex chimney caps and chase covers: The standard galvanized caps sold with many DuraFlex systems rust through in five to seven years in northern New Jersey’s snow load. We upgrade to Gelco stainless or copper caps with welded seams, and we measure on site rather than ordering by rough opening. A cap that sits half an inch proud lets wind-driven rain soak the chase framing.

Our DuraFlex Chimney Repair Process

1. 1
   Call and schedule: A live person answers at (973) 604-2986, any hour. We ask about the appliance type, the DuraFlex product if you know it, and what you’re seeing. We book a window that day or the next.
2. 2
   Level-2 camera inspection: Our technician arrives in uniform, runs a camera the full length of the flue, and photographs every joint, seam, and surface defect. You see the images on the tablet as we find them. No surprises, no guesses.
3. 3
   Plain-English verdict and estimate: Russell or the lead tech explains what’s wrong, what caused it, and what happens if you leave it. We price the repair upfront. The number on the estimate is the number on the invoice.
4. 4
   Parts decision: For DuraFlex repairs, we source OEM-compatible components from our regular suppliers or, when the OEM part is back-ordered or discontinued, a quality aftermarket equivalent that meets the same spec. We never substitute without telling you.
5. 5
   The repair and test: We complete most DuraFlex repairs in a single visit. After the fix, we run a smoke test or draft gauge check to confirm the system draws as designed.
6. 6
   Documentation and guarantee: You get photos, a written report, and our 90-Day Done Right Promise. If it’s not right, we come back. In writing, no arguing.

Why Paterson Homeowners Call Hearthstone Chimney Co. for DuraFlex Work

We’ve been answering the phone with a live person for over 42 years, and we’ve learned that Paterson homeowners don’t want a sales pitch. They want someone who knows that a DuraFlex Elite seam failure in a 1920s Tudor isn’t the same problem as a DuraFlex Pro termination rusting on a 1985 split-level in Hillcrest. Russell Haines and our crew have worked chimneys across Passaic County long enough to recognize the pattern before the ladder goes up.

Our 90-Day Done Right Promise means if the repair doesn’t hold, we make it right - in writing, no arguing. We carry HeatShield and Gelco materials too, so if your DuraFlex repair benefits from a complementary system, we don’t cobble. Background-checked, uniformed technicians. Most jobs done in one visit. A square deal: no surprises on the bill.
