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 Chimney Cleaning in Flushing, NY | Level Two Chimney Flushing
A Flushing Chimney Cleaning & Sweep for DuraFlex runs $289 for a standard single-flue sweep with camera inspection, and $389-$549 when we’re working through a shared rowhouse stack with two or three flues. We’re an independent DuraFlex service provider, not manufacturer-affiliated, and we’ve been pulling creosote and mapping liner conditions out of Flushing’s pre-war attached homes since 2009. The thing that sets our DuraFlex work here apart: we treat every shared chimney stack as a system, not a single pipe, because in Flushing that’s exactly what it is. Call (516) 240-9191 for a written quote before any work starts.
Why Flushing Residents Choose Us for DuraFlex Service
We work on DuraFlex liners in Flushing’s shared-chimney rowhouses every week, which means we see how the brand’s flexible aluminum construction behaves when multiple flues are packed into one 16-inch chase and exposed to Flushing Bay humidity. Corrine Halstead, who runs our Flushing operation, grew up in Queens and has spent nearly two decades doing chimney work across the borough. She trained at LaGuardia Community College and still insists on showing customers the camera footage before quoting anything. That’s how we do DuraFlex work here: evidence first, price on paper second, no exceptions. Our DuraFlex sales & service crews stock genuine OEM components, not whatever’s cheapest at the supply house, because a mismatched top plate on a Flushing rowhouse stack is a leak waiting to happen. Every visit includes a documented photo record under Clause 4 of the Haven Standard. Written scope, written warranty, written price: before we touch anything.
Common DuraFlex Chimney Cleaning Problems We Solve in Flushing
- Torn or kinked liner walls from over-flexing during install. The 1920s-1940s rowhouses around Flushing have narrow, offset clay-tile flues. An installer in a hurry will force a DuraFlex AL liner through a bend it was never designed to make, and the corrugations tear halfway up. We find this constantly. The fix isn’t patching. It’s a correctly sized reline.
- Pinhole corrosion on DuraFlex 304 liners near the top of the stack. North- and east-facing chimneys in Flushing sit in damp salt air off Flushing Bay longer than anything in the interior of Queens. 304 stainless pitts under that exposure. 316L holds up better, and we recommend it for any exterior-facing Flushing flue.
- Liner sagging or pulling out of the tee when the clay flue has spalled. Once the original clay tiles start shedding chunks behind a gas conversion, the flexible liner loses its support. It sags, the tee disconnects, exhaust leaks into the chase. In a shared Flushing stack, that exhaust can migrate into the neighboring unit’s living space.
- Creosote packing along liner corrugations in wood-burning inserts. We see DuraFlex liners that were sized for an open fireplace, then adapted to a smaller insert without a full reline. The corrugations catch creosote faster than smooth-wall tile, and a Flushing homeowner burning wood three nights a week in December will build Class III creosote in six weeks. That’s a chimney fire waiting on a cold night.
- Open abandoned oil flues in the same stack affecting the active DuraFlex liner’s draft. This is the Flushing-specific one, and it shows up in nearly every pre-1950 attached home we service. When the oil flue next to your gas liner is open at the top, your liner’s draft pulls makeup air down the wrong channel, and flue gases back up into the house. Every DuraFlex cleaning we do in Flushing includes checking whether that abandoned flue is properly capped.
BeforeAfterDuraFlex Service in Flushing: What Local Conditions Mean for Your Equipment
Here’s the piece of local knowledge that separates a Flushing DuraFlex service call from one in Jackson Heights or Bayside. The Department of Buildings records in Flushing show thousands of pre-1940 rowhouses with original two- and three-flue clay tile chimney stacks. When those homes converted from oil to gas, often in the 1990s, many crews simply abandoned the oil flue, capping it with a piece of sheet metal or leaving it open altogether. So you have a stack with one active gas flue, one dead oil flue, and maybe a bricked-up fireplace opening, all inside the same 16-inch masonry chase. When we run a DuraFlex liner for your boiler, we map every flue in that stack before we pull anything. The active liner’s draft can pull makeup air down the open abandoned flue, which drags exhaust back into an adjacent unit. On 166th Street near Northern Boulevard, we pulled a kinked DuraFlex AL liner out of a 1930s three-flue stack that had been shoved through an offset clay tile flue during a quick gas conversion. The liner had torn at a corrugation halfway up, and the abandoned oil flue next to it was open at the top. We removed the torn liner, capped the abandoned flue with a proper multi-flue cap, and pulled a new DuraFlex 316L liner through the same offset after relining the clay tile with a smooth-wall insulation mix. The draft test on both floors came back clean, and the adjacent unit’s CO alarm stopped tripping. The camera doesn’t negotiate, it just shows you what’s there.
DuraFlex Models & Products We Service in Flushing
We service the full DuraFlex line: DuraFlex 316L, DuraFlex AL, DuraFlex Pro, and DuraFlex 304. The OEM-versus-aftermarket question matters more in Flushing than most places. Genuine DuraFlex top plates, tees, rain caps, and couplers are engineered to seat correctly with the liner’s corrugation profile. Aftermarket parts that “almost fit” create leak points at the joints, and in a Flushing shared stack, a leak point is a CO pathway into someone else’s apartment. We stock DuraFlex 316L components locally for fast turnaround on Flushing relines, and we’ll tell you plainly if your existing liner can be serviced or if it needs to come out. Torn, corroded, or dislodged liners in a shared stack get replaced, not patched. The risk to every unit in the building is too high.
DuraFlex Service Pricing in Flushing
A standard DuraFlex chimney cleaning and Level 2 camera inspection in Flushing runs $289 for a single flue. Two- and three-flue rowhouse stacks run $389-$549 depending on access and how much creosote has built up. Full DuraFlex relines start around $2,200 for a single straight flue and run upward based on stack height, offset difficulty, and whether the abandoned flue needs capping at the same time. You get a written price before anything starts, a written scope that names exactly what we’ll do, and a photo record when we’re done. No surprise add-ons after the tech is already in your home. Call (516) 240-9191 and we’ll give you an exact number. Estimates are free, and they come with pictures.

FAQs - DuraFlex Chimney Cleaning in Flushing
Yes. We do it regularly, but we map every flue in the stack first with a Level 2 camera inspection before determining liner size and routing. Flushing rowhouses built between 1920 and 1950 often have two or three clay-tile flues in a single 16-inch chase, and the offset bends between those flues are where flexible liners tear when installed carelessly. We’ll show you the camera footage before we quote so you know exactly what we’re working with.
In nearly every case, the abandoned oil flue next to your gas liner is still open at the top. The active liner’s draft pulls makeup air down the dead flue, which draws exhaust gases back through the stack and into the neighboring living space. We cap the abandoned flue with a proper multi-flue cap and test the draft on both floors. Call (516) 240-9191 and we’ll diagnose it with a camera while you watch.
Yes, and it should be non-negotiable. A Level 2 inspection under NFPA 211 includes a camera scan of the entire flue interior, which tells us whether the clay tile has spalled, whether offsets are too tight for a flexible liner, and whether abandoned flues in the same stack are open. In Flushing’s converted rowhouses, skipping the camera means guessing, and guessing means a liner that may not fit correctly or may pull exhaust back into the building.
Flushing sits directly adjacent to Flushing Bay and the tidal Flushing Creek, which means north- and east-facing chimney stacks get a steady dose of damp salt air. It accelerates pitting on 304 stainless, particularly near the top plate and cap where moisture lingers. We recommend DuraFlex 316L for any Flushing liner on an exterior-facing exposure. The molybdenum in 316L resists chloride pitting far better than 304, and the cost difference over the life of the liner is modest.
No, and we won’t pretend otherwise. A torn flexible liner is a failed liner. Patching a corrugated aluminum liner with a splice or sealant creates a weak joint that will separate again, and in a Flushing shared stack, a separated liner leaks exhaust into the chase where it can migrate into adjacent units. If the liner is torn, sagging, or pulled out of the tee, we handle Chimney Repair - Flushing by replacing it with a correctly sized DuraFlex liner, and we show you the old one on camera before it leaves the job site. Call (516) 240-9191 and we’ll explain the options honestly.
