Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

How DuraFlex Products Fail - and How We Fix Them
DuraFlex builds solid products, but every chimney system has its weak points. After 29 years of working on Westchester County chimneys, Wendell Pike and his crew know exactly where DuraFlex components give out and what’s worth repairing.
- DuraFlex 316L Relining Pipe - seam separation at the connector bands. This is the big one. The 316L alloy handles acid condensate well, but the pop-riveted bands where sections join can loosen after years of thermal cycling. The telltale sign is a faint metallic rattle when the fireplace heats up, or white crust forming at a joint. We fix this by re-banding the section and checking alignment - a $220 to $410 repair on most Westchester County jobs. Replacement is only necessary when the steel itself has thinned.
- DuraFlex Direct Vent Pro - gasket failure at the pipe-to-fireplace collar. The Direct Vent Pro is a coaxial pipe, and the inner gasket at the appliance collar doesn’t love Westchester County winters. Freeze-thaw cycles up here - especially in areas like Yorktown Heights and Somers where chimneys run colder - break down that gasket and you’ll get exhaust smell in the room. It’s a $145 to $260 fix with an OEM gasket. Some national outfits will tell you the whole unit needs rebuilding. It usually doesn’t.
- DuraFlex Firebox Panels - refractory cracking that’s actually normal. Hairline cracks in DuraFlex ceramic firebox panels are cosmetic unless they open wider than a dime or start shifting. We see this all the time in Westchester County homes after the first few seasons. If the panel is still seated and the crack is hairline, we’ll tell you to leave it alone. If it’s moving, we replace the panel with matching refractory material - usually $180 to $340 per panel depending on the model.
- DuraFlex Flexible Connector - kinking during original installation. This one’s a quiet killer. If the original installer over-bent the flex connector between the fireplace collar and the liner, you get a restricted draft that shows up as smoky startups and lazy flames. We find it with a camera inspection, which we do on every DuraFlex service. Straightening it is a $175 to $280 job; replacing a kinked section runs higher, and we’ll show you the footage before we pick up a tool.
- DuraFlex Termination Cap - rust-through at the weld points, sooner than you’d think. In Westchester County, the combination of winter road salt carried in the wind and acidic exhaust from gas fireplaces eats termination caps from the inside out. A cap with pinholes or separated welds lets water in and draft pressure out. A new DuraFlex-compatible cap installed on a county roof is commonly $165 to $260, and that’s a job we do same-visit if the roof is safe to access.
Our DuraFlex Fireplace Services Process
Here’s what actually happens when you call Top Hat Chimney about your DuraFlex fireplace in Westchester County:
- 1
You call (914) 537-6479. A live person answers. You describe what the fireplace is doing. We tell you the diagnostic fee - $95 inside Westchester County - and book a window that works for you.
- 2
Wendell or one of his crew shows up in a marked truck. Uniformed, background-checked, and on time. He’ll have a real arrival window and call if traffic is worse than expected on the Taconic.
- 3
We run a full diagnostic. Visual inspection of the firebox, burner, glass gasket, and log set, plus a camera run through the flue from the fireplace side. We test draft with a smoke pencil and check gas pressure at the valve where it’s accessible. This is where we find the actual problem - not what a sales guy guessed over the phone.
- 4
We show you the camera footage and give you a plain-English verdict. You’ll see what we see. If the part is OEM-critical like a gasket or connector band, we use OEM where it matters for safety or warranty. Where a good aftermarket part works just as well, we tell you. You get a flat price before any work starts.
- 5
We do the repair or replacement. Most DuraFlex fireplace services are done the same visit. If a liner section needs to come out, that’s typically a follow-up within the week.
- 6
We test it under fire and we leave it clean. If it’s a gas unit, we run it through a full cycle and check for odor, draft, and flame pattern. If it’s wood, we light a small fire or run a draft test. Then we sweep up and go - with the 90-Day Done Right Promise in writing on the invoice.
What DuraFlex Fireplace Services Cost in Westchester County
Here’s honest money for the jobs we actually see in Westchester County, based on calls we’ve run this year:
- DuraFlex fireplace diagnostic + camera inspection: $95 (credited toward any repair we do that day)
- Gas fireplace service - cleaning, burner check, glass gasket, valve check: $145 to $230
- Damper repair or replacement: $150 to $380 depending on type (throat damper vs. top-mount)
- Firebox panel replacement (single panel, refractory): $180 to $340 per panel
- DuraFlex relining pipe section repair (re-band, gasket, alignment): $220 to $410 per section
- Termination cap replacement (installed): $165 to $260
- Full DuraFlex liner replacement for a small fireplace: $1,800 to $3,400 (we only recommend this when the camera shows you can’t patch it safely)
What moves the price: roof height and pitch for cap or top-mount work, how far up the flue the problem sits, and whether the part is still under DuraFlex warranty (many liners carry a limited warranty; we’ll help you file the claim). We don’t add trip charges inside Westchester County. Call (914) 537-6479 for a free estimate - and that number won’t change when the truck shows up.

Wendell Pike founded this company in 1999, and he’s been working Westchester County chimneys ever since. The company is owner-operated, the license number is public, and Wendell puts his name on every job. You’ll see him at the hardware store on Saturday, not just once at your front door.

Phones are answered by a live person around the clock - and late at night, that may well be Wendell himself.
We know DuraFlex components the way a mechanic knows a particular engine. But we also service HeatShield rebuilds and Gelco chimney products, and if your problem would be better served by one of those, we’ll tell you that too. If it doesn’t need doing, we’ll tell you that too. That’s the whole model.
Ask anyone on your street, especially if they’ve been in their house more than five years. That’s how business gets done in Westchester County, and it’s kept Top Hat Chimney alive for over 29 years.
FAQs
Yes. We service DuraFlex fireplaces and DuraFlex liners in Westchester County regardless of who originally installed them. The diagnostic is the same $95 camera-backed inspection, and you get the same flat-price repair quote before we do the work. Your DuraFlex warranty may still apply depending on product age, and we’ll help you figure that out before any repairs are approved.
We are an independent DuraFlex service provider, not a factory-authorized dealer or certified installer. That’s not a downside for you: it means we tell you the truth about parts. We have no quota to sell, no territory to protect, and no reason to talk you into a rebuild that isn’t needed. We buy OEM parts where safety or warranty requires it, and we’ll tell you when a good aftermarket part does the same job for less. Call (914) 537-6479 and we’ll walk you through your options.
Most DuraFlex service calls inside Westchester County are scheduled within two to four business days. Gas fireplace issues where you smell exhaust or gas get priority, and we’ll tell you over the phone whether to shut the unit down until we arrive. We cannot promise same-day service. We’d rather be honest about that than leave you waiting on a crew that doesn’t show.
Often a repair is enough. We make that call with a camera, not a guess. If the steel is still sound and the problem is a connector band or gasket, we fix it and you keep running. If the liner has thinned, separated, or started pitting through, we’ll show you the footage and tell you straight. You’ll never be asked to approve a liner replacement without seeing the evidence with your own eyes. Free estimates for DuraFlex repair and replacement are available at (914) 537-6479.
It applies to every job Top Hat Chimney completes, including DuraFlex diagnostics, repairs, and installations in Westchester County. If the repair doesn’t hold up, or the fireplace doesn’t work the way we said it would, one call brings Wendell and his crew back to make it right at no additional cost. The promise is written at the bottom of your invoice. You don’t have to take our word for it - you can read it before you pay.
