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 Flushing: What to Know First
We repair, service, and maintain DuraFlex fireplace systems throughout Flushing, NY, as an independent DuraFlex service provider. Most DuraFlex fireplace diagnoses run between $95 and $250, with common repairs landing between $300 and $1,800 depending on what the camera finds in the flue. Turnaround is typically 3 to 7 business days for parts-based repairs; cleaning and inspection visits are usually booked within the week. If you own a DuraFlex fireplace or insert and something has changed - smoke rolling back, a new odor, a pilot that won’t hold - call (516) 240-9191 and we’ll get a Level 2 camera inspection scheduled. Written price before any work starts, no exceptions.
This page is for Flushing homeowners with DuraFlex gas fireplaces, wood-burning units, fireplace inserts, and direct-vent systems. If you’re not sure whether your liner or firebox is actually DuraFlex, we’ll confirm it on site. Corrine Halstead, our owner, grew up in Queens and has spent the better part of two decades working chimneys across the borough, including older attached homes near the Flushing Town Hall district.

How DuraFlex Products Fail - and How We Fix Them
DuraFlex makes a solid product line, but every brand has predictable weak points. Here’s what we see in Flushing homes, based on the units we open up:
- DuraFlex 316L liner seam separation in direct-vent fireplaces. The 316L alloy handles Flushing’s humid summers and salt-tinged air better than standard aluminum, but we regularly find seam separation where the liner flexes through offset angles. Symptom: a faint sulfur or combustion smell near the fireplace that gets stronger when the wind shifts. The camera shows a hairline split at the corrugation peak. Fix: section replacement with proper stainless rivets and furnace cement, not foil tape (which fails within a season).
- DuraFlex DuraTech chimney pipe corrosion at the storm collar. DuraTech is a double-wall insulated pipe we see on many Flushing townhouse and colonial installs. The weak point is the storm collar, not the pipe itself. When the collar shifts during Nor’easter wind loading, water gets between the outer wall and the chase top. Symptom: rust streaks on the fireplace face or water staining on the mantel that comes and goes. Fix: we replace the collar, reseal with a high-temp silicone rated for metal flue temperatures, and verify the chase top flashing is still shedding water.
- DuraFlex DuraVent termination cap blockage in wood-burning inserts. The DuraFlex DuraVent cap has a narrower spark arrestor mesh than some aftermarket caps, which means it loads up faster with creosote glaze in shoulder-season fires. A homeowner in Flushing burning weekend fires from October through March will often have the cap mesh half-blocked by January. Symptom: the fireplace starts fine, then drafts sluggish after an hour. Fix: we pull the cap, document the blockage with the camera, clean it, and show you the before/after photos.
- DuraFlex gas insert burner pan warpage on LP conversions. On DuraFlex gas inserts converted from natural gas to liquid propane, we see warpage in the burner pan when the conversion kit was installed without verifying the orifice size against the unit’s BTU rating. Flushing homes on LP delivery (common in the Mitchell Gardens and Waldheim neighborhoods) deal with this more than city-gas homes. Symptom: orange flame tips and sooting on the glass within weeks of a cleaning. Fix: we verify the orifice, check manifold pressure with a manometer, and replace a warped pan with an OEM-spec part rather than bending it back.
- DuraFlex flex connector over-bending behind gas inserts. The DuraFlex flexible gas connector is approved for specific bend radii, and we find installs where someone forced a tight 90° immediately behind the insert to get it to fit in a shallow firebox. Symptom: a faint gas odor only when the unit is off and the room is warm, because the over-bent section develops micro-cracks under thermal cycling. Fix: we replace the connector, reroute with a longer connector or a 90° street elbow, and leak-test the entire gas train with a combustible gas detector before the unit goes back in service.
Our DuraFlex Fireplace Services Process
Every DuraFlex job in Flushing follows the same steps, whether it’s a pilot that won’t hold or a liner that needs section replacement:
- 1
The call. You call (516) 240-9191. A live person answers, asks what the fireplace is doing (or not doing), and books a window. No voicemail tag.
- 2
The camera inspection. We run a Level 2 inspection per NFPA 211, camera down the flue. Corrine’s rule: “The camera doesn’t negotiate - it just shows you what’s there.” You’ll see the footage before we quote anything.
- 3
The written price. We hand you a written scope, written price, and the warranty terms before any work starts. No “we’ll see once we get in there” pricing. This is Haven Standard Clause 1.
- 4
The parts decision. If the job needs parts, we tell you the OEM DuraFlex option and the quality aftermarket option (we also work with HeatShield and Gelco for repair materials). You decide with actual numbers in front of you.
- 5
The repair or service. We do the work, photograph every step, and run the system through a full operation test: pilot, main burner, draft, any electrical components.
- 6
The document handoff. You get a photo record of the job, a copy of the written scope, and the warranty in writing. We keep a copy in our archive too (Haven Standard Clause 4 - running since 2009).

Why Flushing Homeowners Call Level Two Chimney Flushing for DuraFlex Work
Most chimney companies can order a DuraFlex part. Not many can tell you why yours failed, show you the video of it failing, and then give you a written price to fix it. We run the same Level 2 camera protocol on every DuraFlex fireplace, whether it’s a 15-year-old insert in a Kissena Park split-level or a brand-new direct-vent unit in a Murray Hill condo. Our techs are background-checked and uniformed, you get a named technician and a text when we’re on the way, and our live phone line is answered 24/7. If a DuraFlex component is beyond repair and you want to consider alternatives, we also work with HeatShield and Gelco repair systems. And every job - every one - is backed by our 365-Day Done Right Promise: if it’s not done right, we make it right. That’s stamped on every written job record, under the Haven Standard. Thirty-eight thousand inspections and cleanings since 2009, every one with a written price before work started and a documented record when it was done.
FAQs
No. We are not a DuraFlex-authorized service provider, but performing routine service, cleaning, and repair on your DuraFlex fireplace with an independent contractor does not void the manufacturer’s warranty. The warranty covers materials and manufacturing; it does not require that service be performed by a DuraFlex employee. What matters is that the work is done correctly and documented. We hand you a photo record and written warranty on every job, so if a material defect ever gets challenged, you have evidence of how the unit was maintained. Call (516) 240-9191 with your warranty booklet and we’ll walk you through what’s covered before we quote anything.
Most common DuraFlex components - storm collars, termination caps, flex connectors, thermocouples, and pilot assemblies - arrive in our Flushing shop within 3 to 7 business days. Specialty liner sections or longer runs of DuraTech pipe can take up to two weeks. We stock the failure-prone small parts on our trucks, so pilot and connector jobs often get done the same day we diagnose them. We’ll tell you the exact parts lead time on your written quote before you commit to anything.
That’s a math problem we can solve with the camera footage. If the firebox is sound, the liner is intact, and the unit is less than 15 years old, repair usually wins - even a $1,800 liner section replacement costs far less than a $4,000 to $7,000 full insert swap. If the firebox refractory is crumbling, the liner has multiple failed seams, and the unit is burning inefficiently, replacement may be the honest answer. We’ll show you the video, put both numbers in writing, and let you decide. We don’t sell replacements when a repair will hold.
Both. We work on DuraFlex gas fireplaces and inserts, wood-burning units, direct-vent systems, and the liners and caps that connect them. We also handle damper repair, firebox repair, and full fireplace conversions, including gas-to-wood and wood-to-gas. If it vents through a DuraFlex liner or burns in a DuraFlex-listed firebox in Flushing, we service it.
Combustion gases, including carbon monoxide, can enter the living space through the seam gap. That’s the worst case. The more common first sign is staining on the fireplace surround or a persistent odor that gets worse when the wind blows from the north across the Flushing Bay. The point is you won’t know without a camera. Put off the inspection and a $500 repair can become a $2,500 liner replacement or a firebox rebuild. Call (516) 240-9191 and we’ll get a camera down yours. Free estimate.
