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.

AfterFast, Reliable Chimney Repair Across Long Island City
Chimney repair in Long Island City typically runs $375 to $1,850 depending on whether you need mortar repointing, flashing replacement, or a full liner retrofit. Our Long Island City crews complete most repairs in one visit, with a written price delivered before any work starts. If you’re seeing water stains near a chimney breast in Hunters Point, cracked brick facing 5th Street, or loose flashing on a Queens Plaza rooftop, call (516) 240-9612 and we’ll put a Level 2 camera down the flue before recommending anything.
Why Level Two Chimney Jamaica Is Long Island City’s Preferred Chimney Repair Company
Long Island City’s building stock doesn’t behave like the rest of Queens. We work on pre-war brick tenements along 47th Avenue and converted industrial lofts near the East River every week, so our techs already know what they’re going to find before the ladder goes up: cracked clay-tile liners, spalling brick on water-facing elevations, and gas boiler exhausts tied into flues that were engineered for a 1920s manufacturing floor, not a modern condensing unit.
Since 2009, we’ve completed more than 38,000 chimney inspections and cleanings, every one documented with a written price before work and a photo record when the job’s done. That camera-scan practice is Clause 4 of the Haven Standard, and it’s the reason Long Island City homeowners call us for second opinions when another company tells them they need a full rebuild based on a flashlight look.
We answer the phone with a live person around the clock, and our techs are background-checked and uniformed, with license information displayed on every page. Corrine Halstead oversees every repair that leaves our bench, and she reviews the camera footage from each job before a single recommendation is made in writing.
Our Chimney Repair Services in Long Island City
Mortar Repointing
Mortar repointing in Long Island City runs $18 to $35 per square foot depending on access and joint depth. The salt air off the East River and Newtown Creek eats lime mortar faster than anything inland. On pre-war rowhouses in the 40s and 50s streets, we regularly find joints that look intact from the street but crumble under a scratch test. We rake out failed material to a consistent depth and repack with a mortar matched to your building’s original compressive strength, so the new work moves with the brick instead of against it.
Spalling Brick Repair
Spalling brick repair in Long Island City typically costs $45 to $110 per brick replaced, with larger sections priced by square foot at $40 to $90. This is the signature failure mode on Hunters Point waterfront condos and any elevation facing the river. Water gets behind the brick face, freezes, and pops the surface off. On a recent 5th Street loft conversion, we found the upper courses had lost nearly an inch of face depth. We replaced the failed units, corrected the flashing, and applied a breathable waterproofing to slow the cycle. The owner walked away with before/after video and a written scope, because no repair gets recommended without evidence you can see.
Chimney Waterproofing
Waterproofing runs $5 to $9 per square foot of masonry surface in Long Island City. It’s not a substitute for flashing or crown repair, and any company that sells it as one is doing you a disservice. We apply it only after structural repairs are done, and we use a vapor-permeable silane/siloxane blend that lets the brick breathe. Near Newtown Creek, where airborne particulate settles into masonry pores alongside salt, a proper waterproofing application can extend the life of repointed joints by half a dozen freeze-thaw seasons.
Flashing Repair
Flashing repair in Long Island City runs $350 to $950 depending on whether we’re replacing step flashing, counter flashing, or an entire base assembly. On Low-Rise converted loft buildings, the original roofing crew often reused old flashing when the building changed hands, and now it’s separating at the corners. We replace it with Copperfield copper or heavy-gauge aluminum, cut to overlap the masonry joint properly, and sealed with a polyurethane caulk that survives LIC’s summer sun without cracking.

AfterTrusted Brands We Service in Long Island City
We stock DuraFlex stainless steel liners, Copperfield flashing materials, and HeatShield resurfacing products for Long Island City jobs, so we’re not waiting on a supplier to finish your repair. For gas boiler retrofits in converted industrial lofts, we use DuraFlex’s double-wall stainless because it handles acidic condensation without pitting. For homeowners deciding between a liner replacement and a full rebuild, HeatShield’s resurfacing system often saves half the cost while meeting NYC code. We quote all materials at written prices through our buying network before work begins, which keeps your cost honest and locked.
Common Chimney Repair Problems We See in Long Island City Homes
- Unlined industrial flues still in service. Builders tied modern gas exhausts into original factory stacks along Jackson Avenue and the waterfront. The resulting condensation is acidic and eats mortar from the inside out, which is a direct NYC Building Code violation and a DEP complaint waiting to happen.
- Cracked terracotta liners in shared chases. Pre-war tenements on 47th Avenue and nearby blocks run four to six units off one chimney. When the clay tile cracks, flue gases bleed into party walls, and a visual inspection from the roof won’t catch it. Only a camera scan will.
- Salt-driven spalling on river-facing elevations. Buildings on 5th Street, Center Boulevard, and the Hunters Point waterfront lose brick face faster than anything two blocks inland. The East River salt air plus LIC’s freeze-thaw cycles mean a patch without full flashing replacement rarely survives two winters.
- Crown failure from original construction. Many converted warehouse chimneys got a thin mortar cap during renovation. No drip edge, no expansion joint. Water sits on the crown, soaks into the brick, and the spalling follows. We rebuild crowns with a proper overhang and flexible sealant at the flue tile junction.

FAQs - Chimney Repair in Long Island City
Because the original flue was sized for a coal-fired boiler or manufacturing exhaust, not a modern gas appliance. Without a stainless liner insert, acidic condensation from the gas exhaust condenses on those oversized clay or brick walls, eats the mortar from inside, and creates a carbon monoxide path into living space. We install DuraFlex double-wall stainless liners sized to the actual appliance, which is what NYC Building Code requires. Call (516) 240-9612 and we’ll show you the condensation damage on camera before quoting the retrofit.
Salt air accelerates mortar erosion by drawing moisture into the joints and holding it there through every freeze-thaw cycle. On buildings within a few blocks of the river, we see mortar lose structural integrity two to three times faster than similar construction in Middle Village or Elmhurst. Repointing with the correct mortar mix and a penetrating waterproofing treatment slows that cycle. A camera inspection will show you whether your joints are still sound or already failing.
Usually yes, if the damage is limited to the outer brick face and the structural wythe behind it is intact. We replace the failed units, correct the flashing that caused the water intrusion, and rebuild the crown with a proper drip edge. If the inner brick is also compromised, a partial rebuild above the roofline is the honest fix. We’ll show you camera footage before recommending anything, and the written price will reflect what’s actually needed, not what a salesperson could talk you into.
A Level 2 inspection puts a camera down the flue and scans the interior of the shared chase, which is where four-unit pre-war buildings on streets like 47th Avenue hide their real damage. Cracked terracotta liners, gaps at the tile joints, missing mortar between clay sections, and moisture staining inside party walls all show up. You get the video, we explain what it means, and you get a written scope with prices for anything that actually needs repair. Call (516) 240-9612 to schedule.
Yes, if the masonry is already in good repair. Waterproofing is a preventative measure, not a fix for existing cracks, so we’d repoint and repair first, then apply a breathable silane/siloxane treatment. For a rowhouse near Newtown Creek, where industrial particulate settles alongside salt air, the treatment typically extends the life of the mortar joints by five to seven seasons. The cost runs $5 to $9 per square foot, and it’s quoted in writing before we start.
Long Island City’s converted lofts and pre-war tenements hide chimney problems that visual inspections miss. We find them with a camera, document them with photos and video, price them in writing, and guarantee the work for a full year.
