How DuraFlex Products Fail - and How We Fix Them

• DF Pro 316Ti mesh cap corrosion at the weld seams. The titanium-stabilized stainless holds up well in most Westchester conditions, but the spot-welded corners on early production runs (roughly 2015-2019) collect salt-laden condensation from Long Island Sound air. We see this especially on homes near New Rochelle’s waterfront. Our fix: cut out the failed seam, TIG-weld a continuous bead, or replace with a later-run cap with improved passivation.
• DFC Flexible Liner termination caps loosening at the storm collar. Thermal cycling in New Rochelle’s freeze-thaw winters works the storm collar screws loose over five to seven years. Water follows the liner back down into the smoke chamber. We reseat with stainless hardware and a high-temp sealant rated for the DFC’s operating temperatures, not generic silicone that cooks off in the first season.
• DuraFlex Pro crown wash cracking above the flue tile. The Pro line’s recommended crown slope is shallow compared to HeatShield or Gelco specs. In New Rochelle’s Beechmont and Wykagyl neighborhoods, where 1920s brickwork settles seasonally, that shallow pitch cracks within three to four years. We rebuild to a proper 4-inch minimum slope with a poured Portland crown or apply a bonded crown coat if the structural concrete is sound.
• DF Pro multi-flue cap sizing mismatches on retrofits. Homeowners sometimes order by flue count without measuring center-to-center spacing. A cap that overhangs by even an inch on a New Rochelle Tudor chimney catches northeast wind and lifts. We measure on-site, fabricate or order to actual dimensions, and anchor with Tapcon screws into the crown, not the brick face.
• DuraFlex 316Ti rain cap spark arrestor clogging with creosote flakes. The fine mesh that makes these caps NFPA-compliant also traps glazed creosote from older New Rochelle fireplaces burned green or unseasoned. Airflow drops, draft suffers, and the cap becomes a hot spot. We remove and ultrasonic-clean the screen where possible, or replace if the mesh is warped from prior overheating.

Our DuraFlex Chimney Cap & Crown Process

1. 1
   Call and schedule. A live person answers at (516) 927-2678, 24 hours a day. We ask about your DuraFlex product line if you know it, the symptoms you’ve noticed, and when you’re available.
2. 2
   Level-2 camera inspection. Our technician arrives in uniform, background-checked, and runs a camera up the flue and across the crown. You see the photos on a tablet. We give you a plain-English verdict: what needs doing now, what can wait, and what was never a problem to begin with.
3. 3
   Parts decision. If your DuraFlex cap is under warranty and the failure is a known defect, we document it for your claim and source OEM replacement. If the warranty has expired or the part is discontinued, we quote a quality aftermarket equivalent from Gelco or Famco that mates correctly with your DuraFlex liner termination.
4. 4
   The repair. Most DuraFlex cap and crown jobs finish in one visit. Crown rebuilds may need a return trip if we pour concrete and it must cure before the cap mounts. We protect your roof and landscaping, work cleanly, and haul away old material.
5. 5
   Post-repair test burn and documentation. We verify draft and cap clearance with a smoke test or draft gauge. You get photos of the completed work, a written summary, and our 90-Day Done Right Promise in writing, no arguing.
6. 6
   Cleanup and closeout. The price on the estimate is the price on the invoice. We do not add trip charges or disposal fees after the fact.

Why New Rochelle Homeowners Call Hearthstone Chimney Co. for DuraFlex Work

We have been answering the phone with a live person for over 42 years, and we plan to be in New Rochelle in thirty more. That changes how we treat a customer.

Our 90-Day Done Right Promise is in writing, no arguing. If a DuraFlex cap seal fails or a crown crack reopens, we come back. Our technicians are background-checked, uniformed, and trained on DuraFlex, HeatShield, and Gelco systems - not just one brand. When a DuraFlex part is back-ordered or discontinued, we have alternatives that fit and function, not substitutes that almost work.

Russell Haines, our owner, has run his brush through flues across Westchester County for the better part of two decades, including plenty of older Colonial-era stacks in New Rochelle’s Beechmont neighborhood where the mortar tells stories the owners never knew. He learned the trade hands-on after completing a vocational program at Los Angeles Trade-Technical College, then put in years of real-world work before the soot settled and chimney cleaning became his full-time calling. “Tell me what’s burning, and I’ll tell you what’s wrong.” That is still how we operate.

Photos you can see. A plain-English verdict. A square deal: no surprises on the bill.
