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 Yonkers
A standard chimney sweep in Yonkers typically runs $180 – $320 for a single flue, and our crew handles most jobs in about an hour from setup to cleanup. If you own a brick row house or two-family in Park Hill, Nodine Hill, or Southwest Yonkers, your chimney almost certainly predates modern liners, and that changes what a sweep needs to accomplish. We work those old coal-era stacks every week, and we know what to look for before we ever climb onto the roof.
Call (336) 863-3889 and you’ll get a live person, not a voicemail tree. We’ll give you a written price before any work begins, and we’ll tell you the technician’s name and show you their photo before they arrive. That’s how Ruben Castellano has run Alcott Chimney Sweep since 2002, and it’s the only way we work in Yonkers.
Why Alcott Chimney Sweep Is Yonkers’s Preferred Chimney Sweep Company
Yonkers is not Scarsdale, and it’s not the Bronx. The housing stock here is dense attached brick, built between 1890 and 1940 for coal stoves, and then repurposed three different ways over a century. A sweep company that mostly works newer single-family homes in northern Westchester doesn’t know what lives inside a shared Park Hill stack. We do, because we’re in those rooflines constantly.
Our Chimney Sweep crew handles two- and three-family buildings where both units vent into one masonry chimney, and that means we inspect each flue as its own job. A clean flue on the first floor means nothing if the second floor’s flue is dumping creosote behind the same brick. We sweep both, we camera what we can’t see, and we tell you plainly whether a liner is needed or whether the flue can safely wait another season.
Every Alcott technician who works in Yonkers is background-checked and identity-verified through the Threshold Standard before they ever step onto your street. You’ll see their name and photo before arrival, and they’ll show a photo ID badge at the door. No exceptions, ever. That matters to homeowners who are often home alone, parents with young kids, and older residents who want certainty about who’s walking through the door.
Gas Fireplace Cleaning in Yonkers
Gas Fireplace Cleaning in Yonkers usually costs $150 – $260, and it’s one of the most skipped maintenance jobs in attached brick housing where an original coal flue now vents a modern gas insert. The firebox glass fogs, the burner ports clog with dust and pet hair, and the flue holds condensation that corrodes mortar from the inside. A gas fireplace doesn’t produce creosote, but it absolutely needs cleaning and inspection.
What the job includes
We remove the glass and logs, vacuum the firebox, clear the burner ports, polish the glass with ceramic-safe cleaner, and inspect the venting run. On Yonkers gas fireplaces venting through original masonry, we check for condensation staining and mortar debris at the base of the flue, which tells us whether the liner is still sound. You get a plain-English report, not a sales pitch.
When to book it
If you burn your gas fireplace more than twice a week from November through March, book one cleaning per year. If the flames burn yellow or lazy, or you smell a faint musty odor when the unit runs, don’t wait. Those are draft problems, and in Yonkers they usually trace back to the shared flue architecture, not the gas unit itself.
Chimney Maintenance in Yonkers
Chimney Maintenance in Yonkers is a seasonal necessity, not an optional upgrade, because west-facing ridgeline stacks absorb moisture-laden wind off the Hudson year-round and then freeze-thaw through every winter. A crown that cracks in February lets water into the flue liner by March. In attached row houses, a failed cap on one unit’s flue sends water into the neighbor’s firebox too, and that’s the kind of cross-contamination we see constantly.
Annual sweep and inspection
We recommend one sweep and one Level 1 inspection per year for any Yonkers chimney that’s actively used. The sweep removes creosote, soot, and debris; the inspection checks the cap, crown, mortar joints, damper, and firebox. On older brick structures we’re also looking for spalling brick faces and eroded mortar beds, both of which worsen fast in Hudson-adjacent humidity.
Preventive repairs
We repair crowns, replace caps, repoint mortar, and install or replace dampers as preventive work so you’re not paying for water damage inside the flue. On Yonkers homes with original coal-era stacks, we may recommend a waterproofing treatment to slow moisture absorption. Every repair gets a written guarantee, and if it fails within the coverage period, the second visit is free. That’s the 365-Day Done Right Promise, backed in writing.
Trusted Brands We Service in Yonkers
We carry and install professional trade materials only: DuraFlex liner systems for high-efficiency gas appliances, HeatShield resurfacing for fireboxes and smoke chambers, and Famco caps and dampers where the original hardware is beyond repair. These are the brands chimney professionals specify, not box-store substitutes. Because we stock these parts locally for Yonkers work, we can often complete a liner or cap replacement in one visit instead of scheduling a follow-up for parts.
Common Chimney Sweep Problems We See in Yonkers Homes
- Shared flues in attached housing. Two- and three-family row houses in Park Hill and Nodine Hill often vent multiple appliances into one brick stack. If your neighbor’s boiler backdrafts, the exhaust can enter your unit on a floor with no smoke or CO alarm. We inspect each flue separately, even when they share the same masonry.
- Coal-era flues repurposed without relining. Most Yonkers chimneys from 1890 to 1940 were sized for coal stoves, then converted to oil, then to gas, often without a clay-tile or steel liner ever being installed. Oversized, unlined flues create weak draft and let creosote condense low in the stack, where a visual inspection can miss it. A Level 2 camera inspection shows what’s actually there.
- Freeze-thaw crown failures on west-facing stacks. Homes along the Hudson ridge in Yonkers catch constant moisture-laden wind. Water seeps into micro-cracks in the crown, freezes, expands, and cracks the crown wider each winter. By spring, water is inside the flue and firebox. We see this pattern on nearly every west-facing chimney we sweep here.
- Missing or deteriorated caps on multi-family buildings. A missing cap on a three-family in Southwest Yonkers lets rain, leaves, and sometimes birds into every flue that shares the stack. A $120 cap replacement prevents what we too often find: a soaked flue, rusted damper, and a Level 2 inspection bill that’s triple what the cap would have cost.

FAQs About Chimney Sweep in Yonkers
Yes. Each flue is its own vent, even when both sit inside the same brick stack, and we sweep and inspect each one separately. In Park Hill and Nodine Hill two-families, this matters because one unit can run clean while the other is loading creosote, and a shared stack means the condition of one flue affects the other. We quote per flue, not per building. Call (336) 863-3889 for a written price on both flues.
No. Yonkers sits under Westchester County and New York State code, not NYC Building Code or FDNY rules, even if you’re a few blocks north of the Bronx border. Homeowners near the line frequently assume the stricter NYC relining requirements apply to their chimney, and that assumption causes confusion on both sides of a sale or a rental inspection. If you need clarity on which standard governs your property, we’ll tell you plainly before any work is quoted. Call (336) 863-3889.
Because your chimney sits on the western face of Yonkers’s ridgeline, exposed to moisture-laden wind off the Hudson, and the original coal-era crown was built with mortar that wasn’t meant to handle a century of freeze-thaw cycling. Each winter, water in micro-cracks freezes, expands, and widens the cracks. The durable fix is a rebuilt crown with proper expansion properties, which we do as preventive work before the flue interior gets damaged. Call (336) 863-3889 for a crown evaluation.
Third-degree creosote, the hard, glossy, tar-like buildup that coats flues when exhaust cools too quickly, usually cannot be fully removed by sweeping alone. On Yonkers coal-era flues with no clay-tile liner, the creosote has often bonded directly to the brick, and a sweeper that tries to chisel it out risks damaging the masonry. The durable fix is a stainless liner, like DuraFlex, installed to create a smooth, safe venting path. We’ll camera the flue first and show you exactly what’s there before recommending anything.
Usually not. An original coal flue in Yonkers was sized for a coal stove, not for a modern gas boiler and a fireplace venting together. Two appliances into one flue without proper relining creates draft competition, condensation, and the real possibility of exhaust backdrafting into the living space. We were called to a three-family on Park Hill where a basement boiler was pushing gas odor into the first-floor living room through exactly this setup, and the fix required separate liners. If your setup sounds like this, book a Level 2 inspection. Call (336) 863-3889.
