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.

We’ll be there when we say.
Calls come to a live person, not a voicemail tree. That’s been true every day, every hour, for over four decades. Russell Haines built this company on the K.E.Y.S. code - Krafted right, Every time, Your home first, Standing behind it - and we still answer to that standard on every Yonkers job.
Our Fireplace Services in Yonkers
Gas Fireplace Service
Gas fireplaces in Yonkers’s converted two- and three-family homes often run into a problem the original 1920s builders never anticipated: the flue was sized for a coal furnace, not a 30,000-BTU gas insert. That oversized flue runs too cold, condenses moisture, and corrodes the liner from the inside out. We service the burner assembly, check the pilot and thermocouple, and run a camera to confirm the flue is actually venting - not just drafting into the neighbor’s breach. In Greystone and Dunwoodie, we’ve found gas fireplace exhaust spilling back into living rooms because the shared stack had a failed liner two units over. We document everything with photos you can see and a plain-English verdict.

Wood Burning Fireplace
Wood burning in Yonkers means dealing with chimneys that were built tall and wide for coal, then never properly resized. The result is sluggish draft, accelerated creosote buildup, and cold hearths that smoke into the room. We sweep to NFPA 211 standards, inspect with a Level 2 camera, and tell you honestly whether your flue is safe for another season or needs relining. In the hilltop neighborhoods above Riverdale Avenue, we also check for wind-driven downdraft - the Hudson Valley corridor pushes serious pressure onto chimneys above 200 feet elevation, and a standard cap won’t always solve it. We’ve fitted wind-resistant caps from Famco and Copperfield for Yonkers homeowners who were told their fireplace “just drafts poorly.” It doesn’t. It needs the right fix.

Fireplace Insert
Inserts are our most common installation in Yonkers, and for good reason. A properly sized insert with a stainless liner transforms an oversized, drafty coal-era firebox into an efficient heat source. We measure the existing opening, match the insert to your heating needs, and run a continuous DuraFlex liner from the insert collar to the top of the chimney. The critical step most crews skip: we verify the flue doesn’t share a party-wall breach with an adjoining unit. In Ludlow and Lowerre, we’ve found insert installations that appeared to vent fine in calm weather but dumped exhaust into the neighbor’s living space on windy days. Our Level 2 inspection catches that before we seal anything in place. Done right - and we stand behind it.

Damper Repair
A stuck or rusted damper in Yonkers is rarely just a damper problem. In these old brick chimneys, the damper frame is often embedded in mortar that’s been saturated by decades of roof leaks or flue condensation. We remove the damaged assembly, repair the firebox throat with HeatShield refractory mortar if needed, and install a new damper that seals properly. For chimneys with severely degraded throats, we sometimes recommend a top-sealing damper from Gelco - it seals at the chimney crown instead of the firebox, which solves both the draft and the water-intrusion issues common on Yonkers’s flat-roofed row houses. We give you the option, the price, and our honest recommendation. No surprises on the bill.

Firebox Repair
The firebox in a Yonkers brick home takes a beating. Eighty to a hundred years of thermal cycling cracks the refractory panels, erodes the mortar joints, and opens gaps where heat can reach the combustible framing. We rebuild with industry-rated refractory materials, tuckpoint with high-temp mortar, and verify clearance to combustibles with a camera where direct sight isn’t possible. In attached homes with shared party walls, we also inspect the common masonry for heat transfer to the adjoining unit - a safety check that single-family chimney sweeps often miss. Photos you can see, a plain-English verdict. That’s how we work.

Fireplace Conversion
Converting a wood fireplace to gas - or upgrading an old gas log set to a sealed insert - requires more than running a line and dropping in a burner. In Yonkers’s multi-flue chimneys, we verify which flue actually serves your unit, confirm it’s not compromised by a neighbor’s deteriorating liner, and size the new appliance to the available venting. We’ve seen conversions that “worked” until the first cold snap revealed a shared-stack breach that only pressure-tested under temperature differential. We test before we sign off. The 90-Day Done Right Promise covers our conversion work in writing, so if the draft doesn’t perform as specified, we return and make it right.

Trusted Brands We Service in Yonkers
We stock professional-grade materials from the brands that tradespeople actually trust: DuraFlex stainless liners, HeatShield refractory restoration systems, Gelco and Famco caps and dampers, and Copperfield chimney accessories. Our trucks carry the common sizes for Yonkers’s standard flue dimensions, so most repairs don’t wait on a parts order. When a Greystone homeowner needs a wind-resistant cap or a Dunwoodie two-family needs a liner relined before the heating season, we’ve got the inventory to finish the job in one visit. No builder-grade substitutes. The materials we use are the same ones we’d install in our own homes.
Common Fireplace Services Problems We See in Yonkers Homes
- Shared-stack carbon monoxide risk. In attached brick homes across Dunwoodie, Fleetwood, and Ludlow, one chimney structure often carries flues for two or three separately owned units. A cracked liner or failed mortar joint in your neighbor’s flue can vent exhaust into your living space. Our Level 2 inspection documents these breaches with photos and flags cross-property liability in writing.
- Hilltop wind reversal. Yonkers’s elevation rise from the Hudson River to Greystone and Dunwoodie Heights creates serious downdraft pressure on chimneys. Gas fireplaces that spill exhaust on windy nights aren’t “sensitive” - they’re fighting a pressure battle that requires proper cap selection and sometimes flue resizing.
- Oversized coal-era flues. The original builders sized these chimneys for coal furnaces, not modern low-BTU gas inserts. Cold, oversized flues condense moisture, accelerate liner corrosion, and trap creosote that brushes can’t fully remove. We measure, we camera, we tell you if relining is the honest next step.
- Spalled clay tile in 80-130-year-old liners. Yonkers’s housing stock is among the oldest in Westchester County, and the clay tile liners are simply exhausted. Cracked, flaked, or missing tiles are a near-universal finding in our inspections. We can reline with DuraFlex stainless or restore with HeatShield - we don’t default to the more expensive option unless it’s actually necessary.

FAQs - Fireplace Services in Yonkers
Yes, we clean and inspect your flue independently, but we also camera the shared masonry to check for breaches that could vent your neighbor’s exhaust into your space or vice versa. In Yonkers’s two- and three-family attached homes, this cross-property check is standard in our Level 2 inspection. If we find a shared-stack issue, we document it with photos and a written flag so both owners have the facts. Call (516) 927-2678 to schedule - estimates are free.

Wind-driven downdraft from the Hudson Valley corridor is pressurizing your flue, and if the liner is oversized for your gas insert, the exhaust doesn’t have enough momentum to overcome it. We see this routinely in Fleetwood and Greystone, where hilltop elevation amplifies the effect. A pressure test and camera inspection confirm the cause; a properly sized liner and wind-resistant cap usually solve it. Call (516) 927-2678 and we’ll sort out whether it’s a cap issue, a liner issue, or both.

Most Yonkers fireplaces need a Level 2 inspection, which includes internal camera imaging of the flue. Level 1 is a visual check without tools - adequate for a new installation but not for an 80-year-old chimney with unknown history. Level 3 involves dismantling structure and is reserved for suspected hidden hazards. Given the age of Yonkers’s housing stock and the prevalence of shared-stack configurations, we recommend Level 2 for every initial inspection. You’ll get photos you can see and a plain-English verdict. Call (516) 927-2678 to book.

In most cases, yes. We can install a continuous DuraFlex stainless liner or apply a HeatShield cerfractory seal depending on the extent of damage and the flue’s configuration. Rebuilding is only necessary if the exterior masonry is structurally compromised, which we assess during our Level 2 inspection. For Dunwoodie’s shared-stack chimneys, we also verify that relining your flue doesn’t leave a breach in the party wall exposed to the neighbor’s side. We’ll show you the camera footage and explain your options with exact pricing. Call (516) 927-2678 for a free estimate.

Even occasional burning in an oversized, coal-era flue can produce dangerous creosote accumulation because the flue runs too cold to vent properly. For Yonkers’s older housing stock, we recommend an annual Level 2 inspection and sweep regardless of use frequency. Gas fireplaces should be inspected annually for burner condition, venting integrity, and shared-stack breaches that don’t depend on how often you light a fire. The inspection itself is the safeguard. Call (516) 927-2678 to schedule - our $89 Seasonal Tune-Up covers the essentials.
