Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Fast, Reliable Chimney Sweep Across Yonkers
A chimney sweep in Yonkers typically costs $189 to $329, depending on the flue condition and how long it’s been since the last cleaning. We service every neighborhood from Park Hill to Getty Square to Crestwood, with crews that know pre-war row houses and steep hillside access better than anyone. If you’re seeing soot streaks, smelling a campfire odor indoors, or just can’t remember the last time the flue was brushed, call us at (914) 233-3156 and we’ll get you on the schedule with a written quote before anyone climbs a ladder.
Yonkers chimneys aren’t like the ones in newer Westchester suburbs. They’re old. They’re often shared between attached homes. And they frequently vent appliances they were never designed for. That’s exactly why we lead with a camera inspection on nearly every job here. You see what we see, and you get a recommendation backed by footage, not a guess made from the rooftop. Our Chimney Sweep team handles everything from a simple soot removal to full stainless relining, and we’ll tell you plainly when a sweep is all you need and nothing more.
Why Hadley Chimney Yonkers Is Yonkers’s Preferred Chimney Sweep Company
Hadley Chimney Yonkers has built its reputation in Yonkers on one thing: showing homeowners the actual condition of their chimney before recommending any work. That’s not common in this trade. In a city with this many pre-WWII buildings, shared-party walls, and original coal-era flues, the difference between an honest sweep and a five-thousand-dollar upsell often comes down to five minutes of camera footage. We show the footage. Every time.
Cory Mitchell, who leads our crews, started Hadley Chimney Sweep in 2003. The company has spent more than two decades refining a process that removes the guesswork. We arrive in a tracked window, not a four-hour range. We wear uniforms, we’re background-checked, and we carry DuraFlex, HeatShield, Gelco, and Olympia Chimney materials on the truck so most common repairs don’t require a second visit. Yonkers homeowners regularly tell us the same thing: they finally know exactly what was done, because we photograph it before and after and send a digital invoice they can pay from their phone.
Every job we do in Yonkers is backed by the 365-Day Done Right Promise. If a repair fails within a year, we return and make it right, free. That’s a written guarantee on every repair, not a verbal assurance. We also operate under The Relay Visibility Guarantee as part of the Relay Home Co. family, which means live arrival tracking, before-and-after photo documentation, and a written price before work begins are standard on every visit. Not just the big jobs. Every job.

Gas Fireplace Cleaning in Yonkers
Gas fireplace cleaning in Yonkers is a service many homeowners don’t realize they need until the glass fogs permanently or the burner starts popping instead of lighting cleanly. Gas fireplaces still accumulate soot, dust, and mineral buildup on the logs, burner ports, and glass. In Yonkers, where many older homes converted from oil or wood to gas over the years, we often find the gas logs installed inside a firebox that was never properly cleaned before conversion. That leaves old creosote (the flammable tar buildup that makes chimneys a fire risk) sitting behind the gas burner, which is exactly what you don’t want.
What a Gas Cleaning Covers
We remove the logs and glass, clean every burner port, vacuum the firebox, and clear any debris from the flue path. If you have a direct-vent gas unit, we check the vent termination outside for blockages. You get photos of the firebox before and after, so you can see the difference. Gas fireplace cleaning in Yonkers typically runs $149 to $249, and it usually takes under an hour.
When Yonkers Homeowners Should Book This
Book it if you notice soot film on the glass that cleaning doesn’t remove, a lazy yellow flame instead of a crisp blue one, or any smell when the fireplace runs. Also book it annually just before heating season. Yonkers gets enough cold snaps that you’ll want the fireplace working reliably by late October.
Chimney Maintenance in Yonkers
Chimney maintenance in Yonkers is not optional if you live in one of the city’s older homes. Freeze-thaw cycles up here are brutal on masonry. Water seeps into tiny cracks, freezes, expands, and slowly spalls the brick and mortar. After enough winters, you get crumbling crowns, loose bricks, and water staining on interior walls near the flue. A maintenance visit catches these problems early, when they’re a $200 repair instead of a $4,000 rebuild.
Annual Sweep and Inspection
We recommend an annual sweep and Level 1 inspection for any Yonkers fireplace that gets used more than a few times per season. The sweep removes creosote and soot. The inspection checks the crown, cap, flashing, and firebox for early damage. Annual maintenance in Yonkers typically runs $189 to $289 for the sweep, with inspection included.
Waterproofing and Crown Repair
Yonkers chimneys take more water exposure than most people realize, especially on steep hillsides where wind-driven rain hits the stack harder. We apply chimney-specific water repellents and repair cracked crowns before water gets behind the brick. If you see white staining (efflorescence) on the exterior brick, that’s water working its way through. We’ll find the entry point and stop it.
Trusted Brands We Service in Yonkers
We work with materials chimney professionals actually rely on, and we keep common parts stocked for Yonkers customers so repairs don’t stall waiting on a shipment. That includes DuraFlex flexible stainless liners, which we use constantly in Yonkers because older flues are often too narrow or oddly shaped for rigid pipe. We also carry HeatShield cerfractory repair compound for restoring damaged clay tile liners without a full teardown, and Gelco chase covers and caps for newer pre-fab chimneys. When a Yonkers walk-up needs a reline, we usually have the right liner on hand and can complete the job in one trip.
We proudly serve the entire city of Yonkers, and our Yonkers customers get priority scheduling when winter weather creates a backlog of chimney emergencies.

AfterCommon Chimney Sweep Problems We See in Yonkers Homes
- Original coal-era chimneys venting modern gas appliances. Many homes in Park Hill and Getty Square still run furnaces and water heaters into flues built for coal smoke. These flues are often unlined or have clay tiles that can’t handle the moisture from gas exhaust, making an annual sweep and inspection critical.
- Shared-party wall chimneys with hidden flue damage. In Yonkers’s dense row house blocks, two homes often share one chimney structure. A crack on your neighbor’s side can pull smoke into your flue, and a camera inspection is the only way to see what’s actually happening inside the stack.
- Cracked crowns from freeze-thaw cycling. We see this constantly. Water gets into the crown, freezes, and splits the concrete. Then water runs down the flue and deteriorates the mortar joints from the inside. In Yonkers, we recommend crown checks every year, not every few years.
- Creosote buildup in seldom-used fireplaces. Humid Yonkers summers can make creosote sticky and more likely to bond to flue walls, even if you only burned a few fires last winter. Then the fireplace sits damp for months, and the creosote hardens into a glaze that’s harder to remove and more flammable than dry, flaky buildup.
Pricing for Chimney Sweep in Yonkers, NY
A standard chimney sweep in Yonkers runs $189 to $329. Most single-flue sweeps land around $219 when there’s normal creosote buildup and straightforward roof access. If you have a three-story walk-up, a steep hillside roof, or a flue that hasn’t been cleaned in many years, expect to pay toward the higher end because the job takes longer and requires more care. Gas fireplace cleaning in Yonkers runs $149 to $249. A Level 2 camera inspection, which we strongly recommend for any Yonkers home with an original chimney, runs $249 to $399 depending on the number of flues and how many appliances vent into the stack. You’ll always get a written quote before we start, and the price won’t change at the door. Call (914) 233-3156 for a free estimate.

FAQs About Chimney Sweep in Yonkers
The only reliable way to know is a Level 2 camera inspection. In Yonkers, where many chimneys still have original clay liners, we frequently find homeowners were told they need a full reline when the actual problem is a cracked crown or a few deteriorated mortar joints. We show you the camera footage and explain what’s actually happening before we recommend anything. If a reline is needed, we’ll show you exactly why on screen, and the quote will be for the flue, not a whole chimney rebuild. Call (914) 233-3156 to book an inspection.
Usually yes, after a sweep and a Level 1 inspection to confirm the flue is intact and clear. But older Getty Square walk-ups often have narrow flues that were built for coal, and some have been venting gas appliances for decades. If the flue has deteriorated or the clay tiles are cracked, we’ll tell you honestly whether it’s safe for wood burning or whether it should remain gas-only. A used fireplace with a damaged liner can leak heat and gases into walls, so this is one area where you want the camera evidence. Give us a call and we’ll walk you through what’s typical for your building type.
Yes, and we see the proof every winter. Yonkers gets enough freeze-thaw cycles each year to split masonry crowns, spall brick faces, and widen hairline cracks into gaps that let water pour into the flue. Steep hillside homes get hit harder because wind-driven rain drives water into the stack. The fix is usually straightforward: repair the crown, apply a breathable water repellent, and replace any spalled brick. It’s a fraction of the cost of a rebuild, which is what happens if the water keeps getting in. We’ll show you photos of exactly where the damage is.
Yes, but you also need an inspection, and not just a brush. Gas furnaces produce acidic moisture that eats away at old clay tile liners and mortar joints over time. In Yonkers, where many pre-war homes still vent gas appliances into original coal-era flues, we see flue damage that a standard sweep alone won’t catch. A camera inspection shows whether the flue is still safe to vent exhaust. If it’s compromised, the solution may be a stainless reline rather than a rebuild, and we’ll show you the footage so you know it’s necessary. Call (914) 233-3156 and we’ll check your setup.
Book an inspection. White staining on Yonkers brick is typically efflorescence, which means water is moving through the masonry. Crumbling brick means spalling, which is the freeze-thaw cycle actively breaking apart the chimney. Both mean water is entering somewhere, and in Yonkers winters, that problem accelerates quickly. We’ll identify the water entry point, check the crown and flashing, and give you a written quote for the repair. Most of these fixes are far cheaper than homeowners expect, especially when caught in the same season the staining appears.
