This page is for Hempstead homeowners who have a DuraFlex product installed and want an honest read on whether it’s failing, what repair looks like, and what it should cost. We’re an independent DuraFlex service provider, not a factory rep, so you’ll get the truth about parts, pricing, and whether a repair is worth doing.

How DuraFlex Products Fail - and How We Fix Them

DuraFlex makes a solid liner system, but no product survives forever in a Nassau County chimney. Here’s what we actually find when we open up a Hempstead flue and look.

• DuraFlex 316L alloy pitting near the flue cap. Hempstead’s salt air off the Atlantic works on stainless in ways inland chimneys never see. We regularly find pinhole corrosion at the top three feet of 316L liners, right where condensation meets the cap. The fix is a top-section replacement, not a full reline. We’ve saved Hempstead customers thousands by catching this early.
• DuraFlex Pro liner joints separating after freeze-thaw cycles. The Pro series uses a gasket seal at each joint, and Nassau County winters are hard on gaskets. When they dry and crack, flue gas leaks between sections and you may smell smoke in the house on windy days. We reposition the sections, replace the gasket material, and re-lock the joints. Often this is a repair, not a replacement.
• DuraFlex 304 liner warping in oversized flues without insulation. We see this in older Hempstead homes near Hofstra University where original clay tiles were wider than code. An uninsulated 304 liner in a big flue heats unevenly and can warp outward. The OEM fix calls for an insulation wrap, which we install around the liner before reinserting it. This restores draft and the liner’s shape.
• DuraFlex oval-to-round transition cracking at the stove connection. On wood stove installs, the oval DuraFlex connector takes the hot end of every fire. After enough seasons, the crimp connection fatigues and small cracks form at the seam. We replace the transition piece with an OEM DuraFlex part so the stove still meets the manufacturer’s clearance specs.
• DuraFlex masonry feed-through failures at the smoke shelf. Where the liner passes through the old masonry at the smoke shelf, settled brick puts pressure on the liner wall. In Hempstead’s older chimneys, we’ve pulled liners that were crushed nearly flat at that point. The repair is a partial liner section replacement plus masonry stabilization so it doesn’t happen again.

Our DuraFlex Chimney Repair Process

1. 1
   You call (516) 963-1068. A live person answers. You describe what’s happening. We set a real arrival window, not a four-hour shrug.
2. 2
   We show up and inspect. Wendell or a crew member drops a camera down the flue and videos every inch of your DuraFlex liner, top to bottom. You watch alongside or see the footage after. No mystery verdicts.
3. 3
   We give you the plain truth. If the liner’s fine and your issue is actually a bad cap or cracked crown, that’s what we tell you. We don’t sell a reline when a $60 part does the job. If it doesn’t need doing, we’ll tell you.
4. 4
   We quote the repair, parts included. For DuraFlex work, we use OEM parts when they matter for safety or stove clearance, and we’ll tell you when a quality aftermarket part does the same job for less.
5. 5
   We do the work and show you the after-photos. Same camera, same angles. You see what changed.
6. 6
   We hand you the 90-Day Done Right Promise. Written down, stamped, and real. If the repair isn’t holding up, one call brings us back. No charge to you.

Why Hempstead Homeowners Call Top Hat Chimney for DuraFlex Work

We’ve been running chimneys in Hempstead and across Nassau County since 1999. Wendell Pike is the owner, his name is on the door, and he’s the one up on your roof half the time. When we repair a DuraFlex liner, we know what we’re looking at because we’ve pulled hundreds of them out of local chimneys, including plenty near Hofstra University where older homes and older chimneys go hand in hand.

Every job we do comes with the 90-Day Done Right Promise in writing. If it’s not right, we come back. We also service HeatShield and Gelco liners, so if your DuraFlex turns out to be beyond repair, we can give you a straight comparison of what each replacement system actually costs and how they behave in a Nassau County chimney.

The number you hear on the phone is the number on the invoice. We answer calls around the clock, and if Wendell tells you the liner’s got years left in it, that’s the truth, not a sales pitch.
