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 makes a good product. But nothing lasts forever, and in Hempstead’s damp springs and salt air, certain failures show up more often than the warranty paperwork would suggest. Here’s what we actually find when we open up a DuraFlex system that’s not behaving:
- DuraFlex Pro 316: pitting at the inner liner weld seam. In gas fireplace applications near the coast, the 316L stainless holds up well, but we regularly find corrosion pitting right where the spiral seam meets the connector. It’s not a manufacturing defect, it’s chemistry: heated sulfur compounds from natural gas plus Hempstead’s salt-laden humidity attack that seam first. The fix is usually a section replacement with proper 316L, not a patch. Patches on a pressurized exhaust path are a temporary excuse, not a repair.
- DuraFlex 304: condensation pinholes in wood-burning fireplaces. When a DuraFlex 304 liner runs through an exterior chimney chase that never warms up, flue gases condense before they exit. That condensing moisture holds creosote acids against the steel. Pinholes appear. The homeowner smells smoke in the house even when the fire looks fine. We fix it by replacing the affected section and, more importantly, checking the insulation wrap. In Hempstead winters, an uninsulated chase is the root cause more often than the liner itself.
- DuraFlex DL (double-wall): inner wall collapse from overfiring. The DL series has an air gap between inner and outer walls, and that gap is the problem. If someone burns construction lumber or fires the stove too hard too often, the inner wall can distort and touch the outer wall. The air gap is gone, and with it, the insulation value. The symptom is a fireplace that suddenly drafts poorly and a stovepipe that rattles in the wind. We replace the distorted section and show the homeowner how to avoid overfiring. The camera footage does the talking.
- DuraFlex aluminum liners on older gas fireplaces: flutter and draft reversal. Aluminum gets used on low-efficiency gas retrofits. It’s cheap, which is why builders used it. But Hempstead’s wind loads around the taller apartment and condo buildings near downtown create pressure shifts that make those thin aluminum liners flutter. Draft reversal follows. The permanent fix is replacing the aluminum with a proper rigid or heavy-flex stainless liner sized for the appliance. If it’s a liner the manufacturer says is still in tolerance, we’ll leave it alone. Wendell doesn’t sell a job that doesn’t need doing.
- DuraFlex connectors at the fireplace throat: stress cracking from thermal cycling. The connector is where the liner meets the fireplace outlet, and it takes the most abuse. Every fire is a heat cycle, and over years, the constant expansion and contraction work-harden the metal until small cracks open up. We find this on DuraFlex systems of all series in Hempstead, especially in fireplaces that see daily use from November through March. The fix is a new connector, and when we install it, we check the support banding, because a sagging liner puts the connector back under stress within a season.
Our DuraFlex Fireplace Services Process
Here’s how a DuraFlex job goes from first call to final check, the way we’ve done it for over 29 years:
- 1
You call (516) 963-1068. A live person answers, around the clock. It might be Wendell himself. We ask what you’re seeing: smoke in the house, weak draft, a fireplace that hasn’t been serviced in years, or a gas fireplace that won’t stay lit.
- 2
We schedule the visit and show up within the window we gave you. Background-checked, in uniform, with a real arrival time. If the schedule slips, we call.
- 3
Camera inspection, no exceptions. Before we do anything else, we run a camera up the liner and through the firebox. We show you exactly what we see. If it doesn’t need doing, Wendell will tell you. Plain and simple.
- 4
Parts decision: OEM vs. quality aftermarket. Some DuraFlex jobs call for exact factory replacement sections to keep the system within design spec. Other times, a quality aftermarket component of the same material and gauge does the job at a better price. We’ll lay out both options and the trade-offs before we order anything.
- 5
The repair, done right. We clean the firebox, replace or repair the damaged component, reseal all connections, and run a smoke or pressure test to verify the draft and the seal.
- 6
Cleanup, invoice, and the written 90-Day Done Right Promise. We leave the room cleaner than we found it, hand you the invoice that matches the price we quoted up front, and stamp the paperwork with our promise in writing. If the work isn’t right, one call brings us back.
What DuraFlex Fireplace Services Cost in Hempstead
Here’s the honest money, Hempstead pricing as of now:
- Basic DuraFlex fireplace service and inspection: $120 to $170. Camera inspection, firebox cleaning, and a written report with photos. If you just want to know where you stand, this is where you start.
- Gas fireplace service on a DuraFlex vented system: $145 to $210. Clean the burner, check the thermocouple or thermopile, verify the vent path, adjust the flame.
- Damper repair or replacement on a DuraFlex-connected fireplace: $185 to $320. Depends on whether we can rebuild the existing damper or need to swap in a top-mounted unit.
- Firebox repair (minor mortar joints, firebrick replacement) on a DuraFlex-vented fireplace: $140 to $260. We’re talking a half-day job, not a rebuild.
- DuraFlex liner section replacement (connector or short run): $500 to $900. The price moves with the diameter, length, and access. A second-story roof or a steep pitch adds time, not parts cost.
- Full DuraFlex liner replacement in Hempstead’s older chimneys: $1,800 to $3,600. Depends heavily on liner diameter, length, and whether we need a ladder truck or can work from the roof. We’ll show you the camera footage and the measurements before you commit to a dollar.
What moves the price in Hempstead: chimney height, roof access, liner diameter, and how much creosote has to come out before we can even see the metal. Every estimate is free, and there’s no trip charge inside the county. Call (516) 963-1068 and we’ll give you the number before we schedule the truck.
Why Hempstead Homeowners Call Top Hat Chimney for DuraFlex Work
We’ve been serving Hempstead and the surrounding communities since 1999. Wendell Pike started Top Hat Chimney back then, and he still shows up on the job. That matters when you’re paying for fireplace work you can’t see from your living room. You want the person whose name is on the truck to be the one checking the liner, not a stranger who got hired last Tuesday.
Our 90-Day Done Right Promise is in writing on every job. If it’s not right, one call and Wendell is back. No argument, no invoice. We also work with HeatShield and Gelco systems, so if your fireplace setup is a mixed install, we can handle the whole thing rather than sending you to two outfits.
And around here, ask anyone on your street. Someone’s had their chimney done by Top Hat. Wendell runs into his customers at the hardware store and the coffee shop, and he’d rather lose a job than sell one you don’t need. He’s said it for decades: if it doesn’t need doing, he’ll tell you.
FAQs
No. As an independent DuraFlex service provider, we’re not authorized by the manufacturer, but the work we do follows proper installation and material standards. What voids a DuraFlex warranty faster than anything is improper installation or using the wrong fuel. Simple maintenance and inspection from an independent service does not void the warranty. If your system is still under warranty and a covered part fails, we’ll help you document what we found so you can file the claim.
Yes. We maintain relationships with regional suppliers who stock common DuraFlex connector sizes, liner sections, and top plates. Most parts are on Long Island within 24 to 48 hours. If you’ve got a system where the liner is still in production, the fix is fast. If DuraFlex has discontinued a line, we’ll find a compatible replacement and tell you the truth about the trade-offs before you pay for anything. Call (516) 963-1068 and we’ll check availability for your exact model.
Depends on what the camera shows. Small connector cracks or one damaged section usually get a section repair. Pitting across multiple feet of liner, collapse of the inner wall on a double-wall, or a liner that’s the wrong size for the appliance means replacement. We’ll show you the footage and let you make the call. If it can wait, we’ll tell you it can wait. The camera footage and a plain-English verdict, every time, no exceptions.
If you’ve got smoke in the house or a gas smell from the fireplace, call (516) 963-1068 and we’ll schedule you as soon as a crew is available, which is often the same day. Routine service and inspection is usually within a week. We answer the phone with a live person twenty-four hours a day, so you won’t sit on hold or leave a voicemail.
Once a year, burn or no burn. Chimneys break in the off-season too. Condensation, nesting animals, and rust don’t care whether you lit a fire last February. Annual inspection catches small problems before they become liner replacement bills. The flue doesn’t care how the fire looks. It cares how it breathes.
Call Top Hat Chimney at (516) 963-1068 for a free estimate on DuraFlex fireplace services in Hempstead. We’ll answer, we’ll show up, and we’ll tell you the truth about what you need.
