East Harlem’s dense mix of tenement-style walk-ups built before 1920 and large public housing towers from the 1940s-60s means chimney cleaning here is often about maintaining aging flues in buildings with shared venting systems. Neglect one flue and you can affect entire buildings rather than single homes. We’ll explain exactly what we find, show you the camera footage, and put the guarantee in writing.

Why Ashby Chimney New York Is East Harlem’s Preferred Chimney Sweep Company

Since 2002, Ashby Chimney Sweep has operated under the Kingswell Guarantee, and our East Harlem customers call us back because we do what we say we’ll do. Nathan Corliss leads our team, and the standard he set is simple: say the price first, show up in the window, leave it cleaner, put the guarantee in writing, and come back if it fails. That’s the Kingswell Way, and it’s not a slogan. It’s how we work.

East Harlem homeowners have been burned before: a tech who never showed, a price that doubled at the door, a liner that cracked six weeks after the “repair.” We hear those stories on almost every first call. So we built the opposite. Every job gets a written quote before we touch anything. Every repair gets a written guarantee. If a covered repair fails inside the guarantee period, we return at no charge under the 365-Day Done Right Promise. Our techs are background-checked and uniformed, so you know exactly who’s walking into your building.

We’re not headquartered in East Harlem, but our crews serve the neighborhood locally from the New York City office, and we schedule around your building’s access rules. East Harlem superintendents and co-op boards know us by name at this point. We navigate tight roof access, fire escapes, and locked bulkheads without drama.

Chimney Sweep Certified in East Harlem

Chimney Sweep Certified work in East Harlem means more than running a brush up a flue. It means inspecting the full stack, checking the shared venting system in your tenement, and documenting every finding with camera footage. A standard sweep and Level 1 inspection runs $189-$259. If we need a Level 2 inspection because you’re reopening a sealed fireplace or buying the unit, expect $329-$449. We’ll tell you the written price before we start, and the number on the invoice matches the number we quoted at the door.

What a Certified Sweep Covers

We remove creosote and soot buildup from the flue liner (the clay or steel tube that vents combustion gases out of your home), clean the smoke chamber and damper assembly, and run a camera inspection to check for cracks, gaps, or debris. In East Harlem’s older tenements, we also check the shared stack where your flue meets your neighbor’s. If we find third-degree creosote, we’ll tell you plainly, and we won’t just brush it and call it done, especially in humid summer months when tar glaze blocks draft.

When East Harlem Homes Need an Annual Sweep

Every fireplace used more than a handful of times each winter should be swept annually. In East Harlem’s pre-war buildings, we recommend annual sweeping even if you rarely use the fireplace: shared flues carry whatever your neighbors burn, and pigeon debris from roof work settles into sealed stacks. Skip it, and you’re gambling on a chimney fire or carbon monoxide backdraft.

Gas Fireplace Cleaning in East Harlem

Gas Fireplace Cleaning in East Harlem typically runs $129-$199 for a full service, including burner inspection, log set cleaning, and glass removal. Gas fireplaces still produce soot, and exhaust gases still leave deposits inside the flue. In East Harlem’s older buildings, gas fireplaces often vent into shared brick stacks that also serve wood-burning fireplaces in other units. That cross-contamination risk is real: if one neighbor’s gas appliance vents into a flue still serving another unit’s fireplace, you’re breathing whatever the stack pushes back.

Why Gas Fireplaces Still Need Sweeping

Gas burns cleaner than wood, but it doesn’t burn perfectly. Soot accumulates, logs clog with dust, and the pilot assembly collects debris. More importantly, gas appliances produce acidic condensate that eats at clay flue liners over time. In East Harlem’s freeze-thaw winters, a compromised liner spalls and cracks faster. We inspect the full flue path during every gas fireplace cleaning and document what the camera shows.

Shared Stack Concerns for Gas Units

If your gas fireplace vents into a shared tenement stack, you depend on every unit below and above you. A collapsed liner on the fourth floor pushes exhaust into apartments on the third. A sealed-off fireplace on the second floor can hide a bird nest that blocks draft for everyone above. We’ll check the full stack, not just your unit, and we’ll tell you if the problem is yours or your neighbor’s.

Trusted Brands We Service in East Harlem

We stock professional-grade repair materials so East Harlem customers aren’t waiting on parts. For liner replacements and repairs, we use DuraFlex stainless steel liners, HeatShield cerfractory sealant, and Gelco chimney caps. Our trucks carry the materials we’re most likely to need in East Harlem’s housing stock: stainless liner kits for aging clay flues, custom caps for shared stacks, and masonry sealants rated for freeze-thaw cycles. When we quote a repair, we know the materials are available, not “on order.” Fast turnaround matters when your flue is serving six apartments.

Common Chimney Sweep Problems We See in East Harlem Homes

• Shared flue cross-contamination: When one unit in a pre-war walk-up has a collapsed liner or blocked stack, smoke and carbon monoxide push into adjacent apartments. We’ve documented this on East 116th Street near Pleasant Avenue: a 1910 tenement flue plastered over for decades was packed with nesting debris and coated in third-degree creosote tar glaze. We ran a camera inspection, confirmed the cross-contamination risk to the adjacent unit, and installed a new HeatShield liner and chimney cap before restoring draft to all four fireplaces on the line.
• Sealed decorative fireplaces full of debris: Many old East Harlem tenements still have decorative fireplaces sealed off decades ago. When a new resident opens one up, they often find a flue full of debris from roof work or nesting pigeons. Reopening without a camera inspection risks dumping that debris into a neighbor’s unit below.
• Freeze-thaw spalling on shared stacks: Harsh East Harlem winters with repeated freeze-thaw cycles accelerate spalling in older brick chimneys. A stack serving six apartments with crumbling mortar lets water in and gases out. We see this constantly on pre-1920 walk-ups.
• Third-degree creosote in humid summers: Humid summers worsen creosote buildup in rarely used fireplaces. A brush-only cleaning leaves a tar glaze that blocks draft and risks chimney fire. We use mechanical removal and document the before-and-after with camera footage.

East Harlem has one of the city’s highest concentrations of pre-1920 tenement walk-ups still using shared brick chimney stacks, often four to six units venting into a single flue. One sealed-off fireplace can hide a collapsed liner that then forces smoke into neighbors’ apartments. That’s not an edge case here. It’s the standard condition.
