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.

AfterDuraFlex Fireplace Services in Brooklyn: What to Know First
We service DuraFlex fireplace systems across Brooklyn, and most repair calls are diagnosed and quoted the same day, with the work done within the week. You’ll get an honest number before a single tool comes off the truck, because Wendell Pike has been inside enough DuraFlex installs to know exactly what he’s looking at from the moment he steps onto the roof or kneels at the firebox. As an independent DuraFlex service provider, we’re not tied to a manufacturer’s script, which means we’ll tell you plainly when a cleaning is all you need and when a part actually has to go. If you own a DuraFlex fireplace in Park Slope, Bay Ridge, or anywhere else in Brooklyn, call (516) 289-9316 and a live person will answer.
This page is for homeowners who already have a DuraFlex liner, fireplace insert, or vent system and need someone who knows how they behave after a few Brooklyn winters. We don’t sell DuraFlex. We fix it, service it, and keep it running safely.

How DuraFlex Products Fail - and How We Fix Them
DuraFlex makes good liners, but every product has its habits. Here’s what we actually see in Brooklyn homes.
- DuraFlex 316L ovalized at the firebox connection. The oval-to-round transition piece gets pulled out of shape when the damper frame shifts, which happens a lot in older Brooklyn brownstones where the masonry moves with the seasons. Symptom: you see a sliver of daylight or feel a draft behind the surround. Fix: we re-seat the transition with a proper bracket and re-seal the joint with high-temp silicone rated for liner connections. It’s a two-hour job, not a new liner.
- DuraFlex AL294C popping at the seams on direct-vent fireplaces. This shows up mostly on gas inserts where the exhaust runs hot and the intake pulls cold outside air. The temperature swing works the mechanical lock until a seam relaxes. Symptom: a faint metallic rattle when the blower kicks on, or soot you can smell but not see. Fix: we run a camera, find the popped seam, and re-lock it. If the seam has corroded past locking, we quote a sectional replacement rather than a full re-line.
- DuraFlex DuraVent terminations rusting out at the cap spacer. Brooklyn has salt air, and it doesn’t matter how far inland you think you are on Nostrand Avenue. The galvanized cap spacer fails first, long before the liner does. Symptom: water staining on the chase top or rust streaks down the siding near the flue. Fix: swap the spacer for a stainless upgrade and re-flash the storm collar while we’re up there. We don’t sell you a liner over this.
- DuraFlex flexible liner losing its shape after a long burn season. The corrugated wall is designed to flex once during install, not repeatedly. In fireplaces that run every night from November through March, the constant heat-cycling can cause the liner to develop shallow kinks. Symptom: a fireplace that drafts fine on start-up but pushes smoke back when the fire is fully engaged. Fix: we assess with a camera. If the kink is minor and near the top, a pull-cone re-round is possible. If it’s midsection, we quote honest replacement numbers.
- DuraFlex sizing mistakes from a previous installer. This isn’t a product failure, but we see it enough in Brooklyn to name it. A 4-inch liner in a fireplace that needed a 6-inch, or an oval liner forced into a round clay tile. Symptom: the fireplace has never drafted properly, and the previous company blamed the chimney. Fix: we run the numbers on appliance BTU, firebox opening, and flue volume, then install the liner the fireplace actually calls for. Your flue doesn’t care how the fire looks. It cares how it breathes.
Our DuraFlex Fireplace Services Process
Every DuraFlex job follows the same sequence, whether it’s a gas insert in a Sheepshead Bay high-rise or a wood-burning fireplace in a Dyker Heights split-level.
- 1
You call, a person answers. It might be Wendell himself on the line at (516) 289-9316. We ask what the fireplace is doing, pull up any history we have on your address, and schedule a real arrival window.
- 2
The sweep shows up on time and looks first. We don’t start with tools. We start with eyes and ears: the firebox, the damper, the liner, the termination. Then we run a camera up the flue. The footage and a plain-English verdict - every time, no exceptions.
- 3
You get a written number before work starts. No revised estimate at the door. The figure we quote is the figure on the invoice, and it includes the camera inspection report with photos.
- 4
Parts decisions are made with you, not for you. On DuraFlex systems, we’ll use OEM parts when the liner warranty is active or when fitment demands it. If a quality aftermarket part will do the job at half the cost and won’t void anything, we’ll tell you that too. If it doesn’t need doing, Wendell will tell you that straight.
- 5
The repair happens, then the test. After any fireplace service, we fire it up or run the gas system through its cycle while you watch. We check draft, verify clearances, and clean every bit of our mess.
- 6
The 90-Day Done Right Promise goes home with you in writing. If anything we fixed isn’t right, one call brings the crew back at no additional cost. That’s stamped on every job, DuraFlex or otherwise.
What DuraFlex Fireplace Services Costs in Brooklyn
Here are honest ranges for the DuraFlex work we do most often in Brooklyn. These are ballpark numbers, not a quote off the internet. The exact figure depends on your fireplace, your access, and what the camera shows.
| Service | Typical Range |
|---|---|
| Gas fireplace inspection and cleaning (DuraFlex vented) | $180 - $290 |
| Oval-to-round transition re-seal or replacement | $320 - $520 |

What moves the price: roof access and pitch in neighborhoods like Dyker Heights versus a straight front-wall vent on a house in Marine Park. Whether existing parts are salvageable. Whether the liner has to be fully pulled or can be serviced in place. Call (516) 289-9316 and we’ll give you a no-pressure estimate, no trip charge inside our county, and the same respect for your wallet regardless of what the camera finds.
Why Brooklyn Homeowners Call Top Hat Chimney for DuraFlex Work
Ask anyone on your street. We’ve been working Brooklyn chimneys for over 25 years, and Wendell Pike has been up on more local rooftops than he can count.

Every DuraFlex job includes the camera footage and a straight verdict, backed by our 90-Day Done Right Promise in writing. We also service HeatShield and Gelco systems, so if your DuraFlex liner is paired with a coating or crown product from another brand, we don’t send you off to dial someone else’s number. We work with both, and we know how they interact. Senior and veterans get 10% off every job, no expiration.
FAQs
No. DuraFlex warranties are handled through the manufacturer. What we stand behind is our work. If we install a part and it fails within 90 days because of how we put it in, we’re back at no charge under the Done Right Promise. We also don’t make warranty claims complicated for you: if a DuraFlex part fails under warranty, we’ll give you the documentation and photos from our camera inspection so you can file the claim yourself, and we’ll quote the install labor separately.
Most standard DuraFlex 316L and AL294C components are available within a few days through our supply channels. Oddball sizes or specialized terminations can take a week or two. If your fireplace is out of service and the part is weeks out, we’ll tell you before you spend a dollar, and we’ll talk through short-term alternatives if any exist. Call (516) 289-9316 for an honest parts availability answer on your specific unit.
It depends on what the camera shows. A single shallow kink near the top is often repairable with a pull-cone. Multiple seams showing corrosion, or a liner that’s lost its shape across more than a third of its length, usually means replacement is the honest call. We’ll show you the footage and explain the difference. If the liner can safely get another few seasons, we’ll say so plainly. That’s the whole point of hiring an independent.
Once a year, burn or no burn. Chimneys break in the off-season too. For DuraFlex systems, the annual check is where we catch seam relaxation early, before it becomes a draft problem or a carbon monoxide risk. The inspection is camera-based, and you get the footage. If you can’t remember the last time anyone looked up your flue, it’s time.
We run the numbers on your fireplace: BTU input, firebox opening, flue diameter, and draft requirement. If the liner is undersized, the fireplace will never breathe right, and no amount of sweeping will fix it. We quote the correct liner size for your specific setup and install it. You get a flat price before work starts, and the same 90-Day Promise applies.
