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.

Our Chimney Cleaning & Sweep Services in Yonkers

Level 1 Inspection
A Level 1 inspection in Yonkers covers the accessible portions of the chimney: firebox, damper, visible flue, and the exterior stack from the roof. For a rowhouse on a street like McLean Avenue or in the Runyon Heights area, this often means working around adjoining rooflines that make the crown hard to see. We document everything with photos and give you a written record before we leave.

Level 2 Inspection
If you’re buying a Yonkers home or changing fuel types, a Level 2 inspection is the one that matters. It adds a camera scan of the entire flue interior. This is where we routinely find the oversized terra cotta liner problem. A flue built for a 1930s coal furnace is far too large for a modern gas boiler, and the camera shows the acidic condensation damage that results. We match the right flue size to the appliance actually in your basement, not the one the house had when it was built.

Creosote Removal
Creosote removal in Yonkers takes longer here than in a newer suburb because so many homes were built with shared exterior masonry stacks. A neighbor’s oil boiler venting into the same chase can deposit soot and creosote in your flue between cleanings, even if you never light a fire. We remove creosote by class: first-degree is a light soot film, second-degree is a flaky deposit, and third-degree is the hard, glossy tar-like glaze that’s a serious fire hazard. The chimney fire risk in Yonkers is concentrated in these older rowhouses where deposits build on damp, cracked liner surfaces.

Soot Removal
Soot removal applies to oil- and gas-fired flues more than wood-burning fireplaces. In Yonkers, it’s common to find a single exterior chimney stack serving a fireplace, an oil or gas boiler flue, and a water heater flue simultaneously, often with no liner separating them. We sweep each flue individually and document which one connects to which appliance. That flue map matters when the building department asks for it.

AfterTrusted Brands We Service in Yonkers
When a Yonkers rowhouse needs a reline, we use DuraFlex liners for their flexibility in tight, offset flues, HeatShield cerfractory for clay tile repair, and Gelco products for water-sealing and crown applications. These materials are procured through Haven’s buying network, which keeps our customer prices honest compared to wholesale-plus retail. Our Yonkers customers get the same brand-name materials a downtown high-rise would, without the pass-through markup.
Common Chimney Cleaning & Sweep Problems We See in Yonkers Homes

- Shared stacks with unmarked flues. In dense rowhouse blocks of southwest Yonkers, neighboring properties often share a single exterior masonry chimney stack with multiple flues, and owners routinely don’t know which flue connects to which appliance. Yonkers’s building department requires correct flue identification on permits, so flue-mapping is a necessary step before cleaning or liner work can be signed off.
- Oversized terra cotta liners venting modern gas appliances. An original flue built for coal is far larger than what a high-efficiency gas boiler actually needs. The oversized flue never warms up properly, so condensation forms inside and the acidic flue gas slowly eats the terra cotta liner tiles, causing cracks and spalling that we see block after block.
- Cross-contamination from adjacent appliance flues. When an oil boiler and a gas water heater vent into the same unlined chimney stack, soot from the oil side can deposit into the gas side. We clean both flues and document which one carries what. If we recommend relining with DuraFlex, it’s because we can show you the camera images of the contamination.
- Crown and flashing damage from Hudson River humidity and freeze-thaw. The western riverfront neighborhoods of Yonkers get elevated humidity from the Hudson that wicks into porous older brick. That moisture, plus winter freeze-thaw cycling, spalls the chimney crown and accelerates mortar joint failure on exposed rooftops. A crown that looks fine from the street is often the first thing our rooftop camera documents.
Pricing for Chimney Cleaning & Sweep in Yonkers, NY
A standard chimney sweep in Yonkers runs between $189 and $329 for a clean-burning fireplace or oil boiler flue. If a Level 2 camera inspection is added, the combined price lands between $289 and $429, again depending on the size of the stack and how many flues we’re documenting. Relining a damaged terra cotta flue with DuraFlex typically starts around $1,800 and runs higher when the original flue is oversized or the stack has multiple offsets. Why the range? A single-family detached home in Crestwood takes less roof work than a shared three-story stack in Nodine Hill. We never start a job without a written price, a written scope, and a written warranty, per Clause 1 of the Haven Standard. Call (551) 212-3526 for a free written estimate.

FAQs - Chimney Cleaning & Sweep in Yonkers

Yes, when permits are involved. Yonkers’s building department requires correct flue identification on any permit that touches the chimney, which means we have to map which flue connects to which appliance before cleaning or liner work can be signed off. That mapping is included in our Level 2 inspection and documented in your photo report. Call (551) 212-3526 if you’re unsure whether your shared stack needs it.
The rapid cracking is usually caused by condensation in an oversized flue. Many southwest Yonkers rowhouses have original terra cotta liners sized for coal furnaces, and when those flues vent a modern high-efficiency gas appliance, the flue never reaches the temperature needed to dry out. Acidic flue gas deposits eat the clay, and the liner cracks within a few seasons. A camera scan will show the damage directly. We can then determine whether a DuraFlex reline is the right fix.
Yes, especially in attached rowhouses where a shared exterior stack has multiple unmarked flues. If a neighbor’s oil boiler vents into the same chase as your fireplace or water heater flue, soot and creosote can deposit in your chimney between cleanings, creating a cross-contamination risk. We’ve documented this exact pattern in southwest Yonkers. The first step is a camera scan and flue map so you know what’s actually venting where.
Once a year, even if you only use gas. The reason in Yonkers is not wood creosote but condensation. A modern gas furnace venting into an older, oversized flue produces acidic condensation that eats liner tiles. Annual sweeping removes the deposits and lets us document liner condition with the camera. If you own a rowhouse in Nodine Hill or Park Hill, every year is the right cadence. Call (551) 212-3526 and we’ll put you on an annual schedule.
First-degree creosote is a light, dusty soot film that sweeps away easily. Third-degree creosote is hard, glossy, and tar-like-it doesn’t brush out and is a serious fire hazard because it burns at very high temperatures. We see third-degree creosote most often in flues that also have condensation damage, because the damp liner surface grabs and holds the deposits. If we find third-degree creosote, we’ll show you the camera images and measure it, then give you a written recommendation before proceeding.
