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 Sweep Across Bronx
A standard chimney sweep in Bronx typically runs $189 – $319 for a single flue, and most sweeps are completed in under two hours. Multi-flue pre-war buildings cost more because each flue is a separate job, and we price them individually before any work starts. If you’re in Riverdale, City Island, Throgs Neck, Fordham, Tremont, or anywhere across the Bronx, call (336) 863-3889 and a live person answers, day or night.
We’ve worked in Bronx buildings long enough to know that the chimney behind your wall isn’t always the one your boiler uses. Older buildings hide abandoned flues, shared chases, and bricked-off coal vents that most sweeps never check. That’s exactly why our Chimney Sweep team scopes every flue in the chase, not just the one that’s actively venting.
Why Alcott Chimney Sweep Is Bronx’s Preferred Chimney Sweep Company
Bronx homeowners and building managers call us because we explain what we found, show the camera footage, and give a written price before anything gets touched. Ruben Castellano has run Alcott Chimney Sweep since 2002, and the standard he set hasn’t changed: every technician is background-checked, identity-verified, uniformed, and sent to you by name and photo before the visit. That’s the Threshold Standard, and it’s not an optional upgrade.
When we say we serve the Bronx, we mean the whole borough. Pre-war six-unit buildings in Belmont, attached rowhouses in Morris Park, detached estate homes in Riverdale, waterfront properties on City Island. Each has a different flue setup, and we’re familiar with all of them. We coordinate with building management, we work around tenant schedules, and we document everything for the next FDNY boiler inspection.
Every repair comes with a written guarantee that covers the work for a full year. If a repair fails within that period, the second visit is free. That’s the 365-Day Done Right Promise, and it’s written on every job, not buried in fine print.
Gas Fireplace Cleaning in Bronx
Gas Fireplace Cleaning in Bronx homes usually runs $149 – $249, depending on the unit and whether it’s a direct-vent insert or a gas log set in an existing masonry fireplace. Gas fireplaces don’t produce creosote the way wood fires do, but they still collect soot, dust, pet hair, and a white mineral film on the glass that reduces flame clarity and can clog the burner ports over time. In older Bronx apartments converted from oil or wood to gas, the gas log set often sits inside a fireplace that still has old creosote residue inside the smoke chamber, and that should be addressed at the same time.
When Bronx homeowners schedule this
Most calls come in October through December, right before the first cold snap when tenants or owners light the gas logs and notice the flame is lazy, yellow, or smells. We also hear from people whose carbon monoxide detector went off, which is usually the exhaust vent blocked by dust or soot. It’s worth checking the unit annually, even if it only runs a few dozen times a year.
What the cleaning covers
We remove the glass, clean both sides, vacuum the burner, clear the pilot assembly, check the logs for cracks, verify the venting is unobstructed, and run the unit to confirm a clean blue flame. If we find venting damage or a cracked heat exchanger, we’ll say so plainly and show you the photos before recommending any repair. No scare tactics, no upselling.
Chimney Maintenance in Bronx
Chimney Maintenance in Bronx matters differently than it does in the suburbs because most of this borough’s chimneys are part of a multi-flue chase serving several units at once. Annual maintenance usually costs $189 – $319 per flue, and for buildings with three or more flues in the same stack, we quote each one separately in writing before the job. That maintenance includes a sweep, a close look at the flue liner, mortar joints, chimney crown, and flashing, and a written report of anything that needs attention.
Multi-flue buildings need a different checklist
In a six-unit pre-war walkup, one exterior chase can hold the boiler flue, the water heater flue, a kitchen exhaust flue, and at least one bricked-off coal flue that hasn’t been used since the 1950s. Our maintenance visit includes a camera run down any accessible abandoned flue. Cracks or blockages in those dead flues won’t show up as exhaust problems, but they can fail the next FDNY inspection and trigger a violation notice.
Riverdale, City Island, and Throgs Neck homes
Detached single-family homes in those neighborhoods typically have one flue per fireplace, and maintenance is simpler. But the freeze-thaw cycles are just as rough on exposed brick stacks. We check the crown and mortar joints every year, because the Harlem River and Long Island Sound moisture makes efflorescence and spalling a recurring problem on these older chimneys.
Trusted Brands We Service in Bronx
We install and service pro-grade trade materials, not box-store substitutes. That means HeatShield liner repair systems, DuraFlex stainless steel liners, and hardware from Olympia Chimney and Famco. We keep the most common parts for Bronx flue configurations in our New York City stock, so most liner repairs and crown rebuilds don’t require a second trip to complete. If your building needs a HeatShield resurfacing or a DuraFlex liner replacement, we handle the measurement, the installation, and the documentation your management company needs.
Common Chimney Sweep Problems We See in Bronx Homes
- Shared chase, hidden crack: A brush run down the boiler flue alone misses bricked-off coal flues in the same chase, which can hide structural cracks that trigger FDNY violation notices at the next boiler inspection.
- Coal-converted flues: Many pre-war Bronx flues originally vented coal furnaces, then oil, then gas. The terracotta liner now carries mixed-fuel residue, and third-degree creosote glaze in the smoke chamber won’t come out with a brush alone.
- Freeze-thaw spalling: Multi-story exposed brick stacks in Fordham and Tremont take a beating from November through March. A spalling crown and failed mortar joints let moisture into the flue, and no amount of sweeping fixes water coming through masonry.
- CO creep in attached buildings: In rowhouses and apartment blocks, a blocked or cracked flue in one unit can push exhaust toward a neighbor’s living space. Tenants smell intermittent exhaust odor, and by then the flue needs a camera inspection, not just a sweep.
Pricing for Chimney Sweep in Bronx, NY
A standard single-flue chimney sweep in Bronx runs $189 – $319. Gas fireplace cleaning is $149 – $249. A Level 1 inspection (visual check, done with the sweep) is included at no extra charge, and a Level 2 camera inspection runs $199 – $399 depending on the number of flues. If we’re doing a Level 2 on a four-flue chase, we price each flue separately rather than charging a flat per-building fee. Liner repairs and crown rebuilds are quoted in writing, with the exact materials listed by brand. Call (336) 863-3889 and we’ll give you a real number before we arrive, not a vague range that changes at the door.

FAQs About Chimney Sweep in Bronx
Yes, and it usually needs more than a sweep. Oil flues carry thick soot and sulfur residue that a gas burner’s lower exhaust temperature won’t burn off. That residue should be removed, and you’ll want a Level 2 camera inspection before the conversion is signed off. The old terracotta liner may be deteriorated, and the FDNY boiler inspection that follows the conversion will look for exactly that. Call (336) 863-3889 and we’ll scope it before your inspector does.
Yes. We work from the roof when possible and only need access to common areas, not individual units. The sweep itself doesn’t require entry into apartments. If a camera run or liner repair does require access to a specific unit, we coordinate directly with building management and give written notice ahead of time. In most pre-war buildings, we can complete the full scope from the roof and the basement boiler room.
A Level 2 inspection on a multi-flue Bronx chase means a camera run down every accessible flue, not just the active boiler flue. We scan for cracks in the terracotta liner, gaps between flue tiles, blockages, and signs of moisture intrusion. We check the abandoned flues too, because a structural crack in a bricked-off coal flue is still a violation risk at the next FDNY boiler inspection. You get a written report with photos. Call (336) 863-3889 for a free estimate on a Level 2 inspection.
Because the moisture in those neighborhoods does as much damage as the fire does. Riverdale and City Island chimneys sit close to the water, and the persistent ambient moisture from the Harlem River and Long Island Sound accelerates efflorescence and mortar joint failure. A handful of fires still leaves creosote deposits that accumulate over years, and an annual sweep is when we catch the crown cracks and flashing failures before they become a $3,000 masonry repair. Call (336) 863-3889 to schedule.
Hard freeze-thaw cycles from November through March cause the mortar between bricks to expand and contract repeatedly, which produces spalling, cracked crowns, and loose flashing. On a five-story exposed stack in Fordham, those failed joints let water into the flue liner, and the liner then cracks from the inside. By the time you see water stains on the top floor ceiling, the flue has been compromised for months. Annual maintenance catches it while it’s still a $300 mortar repoint, not a $4,000 rebuild.
