AshVanta Chimney Services works throughout the Upper West Side from our office in Yorkville, about a mile away on the other side of Manhattan. We serve homes and buildings in ZIP codes 10023, 10024, 10025 and 10069, from parlor-floor fireplaces in brownstones to boiler flues in pre-war apartment buildings. Our certified technicians sweep, inspect and repair chimneys, install liners, and clean air ducts and dryer vents. Because we're close by, it's easy to set up a visit before the heating season or soon after a storm leaves you with a leak.
Chimneys in Brownstones, Rowhouses and Pre-War Buildings
Much of the Upper West Side is older masonry housing. Brownstone and rowhouse townhouses often have several fireplaces stacked floor over floor, each with its own flue. Pre-war apartment buildings usually have a tall chimney serving a central boiler. Many of these flues were built without a liner, or with clay tile liners that have cracked or shifted over the decades.
Townhouse fireplaces sometimes sit unused for years. Some were closed off, some fitted with gas inserts, and some simply forgotten. Before you light a fire in one again, have it inspected. We look for debris, animal nests, missing or rusted dampers, gaps in the flue and deteriorated firebox mortar, and we tell you plainly what needs attention and what doesn't.

How New York Weather Wears on Masonry
New York winters bring repeated freeze-thaw cycles. Water soaks into brick and mortar, freezes and expands, and over time that opens cracks in the chimney crown and loosens bricks near the top of the stack. Summers are humid, and coastal storms push wind-driven rain against rooftop chimneys from the side.
On the inside of the home, the damage usually shows up as water stains on a ceiling or wall near the chimney breast, flaking or crumbling brick, white mineral deposits on the masonry, or a damper that has rusted and no longer closes. Catching these signs early usually means a smaller repair.
- Chimney caps and chase covers to keep out rain, snow and animals
- Chimney waterproofing that lets masonry breathe while shedding water
- Crown, flashing and mortar joint repair
- Partial or full chimney rebuilding when the masonry is too far gone
Inspections, Sweeping and Liner Work
The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. A Level 1 inspection fits when nothing has changed. A Level 2 inspection is used when the system changes, such as a new appliance or a switch in fuel, or when a home is sold. A Level 3 inspection is reserved for hidden hazards that can only be reached by opening part of the chimney or building.
New York City's heat season runs from October 1 through May 31, and building owners must keep apartments heated to the city's minimum temperatures throughout it. Late summer and early fall are the best times to have a boiler chimney checked. When a building converts its boiler from oil to gas, the chimney has to be evaluated as part of the job, and a new liner is often needed because gas exhaust produces acidic condensate that can corrode a masonry flue.

Dryer Vent and Air Duct Cleaning
According to the U.S. Fire Administration, failure to clean is the leading factor contributing to clothes dryer fires in homes. In townhouses and apartments, dryer vents often run a long way, with several turns, before they reach the outside, so lint builds up easily. If your clothes take longer to dry or the laundry area feels unusually warm, the vent should be cleaned.
For air ducts, we follow the U.S. EPA's guidance. Cleaning makes sense when there is substantial visible mold growth, signs of vermin, or excessive dust and debris. The EPA also notes that duct cleaning has not been shown to prevent health problems. It suggests researching the process before responding to very cheap advertised offers and being careful about chemical treatments. We show you what we find before recommending any work.
Neighborhoods Near the Upper West Side
Along with the Upper West Side, we regularly work in Lincoln Square, Manhattan Valley, Carnegie Hill, the Upper East Side and Yorkville, where our office is. The same kinds of older masonry homes and pre-war buildings are common across these neighborhoods, and so are the same weather-related problems.
