The short answer
AshVanta Chimney Services serves the whole Upper East Side from our Yorkville office about a mile away. We sweep, inspect, repair and reline chimneys in brownstones, townhouses and pre-war buildings, and we clean dryer vents and air ducts. Schedule boiler flue work before heat season starts on October 1.
The Upper East Side has some of Manhattan's most varied chimney work. Brownstones and townhouses have wood-burning fireplaces, some parlor-floor fireplaces may or may not be usable, and pre-war apartment buildings depend on tall boiler flues. AshVanta Chimney Services is based in Yorkville, about a mile away, so our certified technicians work in this neighborhood all the time. We handle sweeping, inspections, repairs, liners, dryer vents and air ducts for homeowners, co-op and condo boards, and building managers across every Upper East Side ZIP code.
Chimneys in Brownstones, Townhouses and Pre-War Buildings
Many Upper East Side rowhouses were built with several fireplaces, often one per floor, sharing a single chimney stack with multiple flues. Over the decades some flues were sealed, some were relined, and some were simply forgotten. If a fireplace hasn't been used in a while, or it came with a home you just bought, find out which flue it connects to and what condition that flue is in before you light it.
In pre-war apartment buildings, the chimney usually serves the boiler, not a fireplace. That flue runs the full height of the building and carries exhaust through the whole heating season. Problems tend to show up there first, including cracked liners, crumbling mortar at the top of the stack, and blocked cleanouts.
Heat Season and Oil-to-Gas Conversions
New York City's heat season runs from October 1 through May 31. During that time, building owners must keep apartments heated to the city's minimum temperatures. A boiler flue problem found in January is much harder to deal with than one found in late summer. We recommend scheduling boiler chimney inspection and cleaning before October, so any repairs can be made while the boiler can safely be shut down.
If your building is converting its boiler from oil to gas, the chimney has to be evaluated as part of that work. A new liner is often needed because gas exhaust produces acidic condensate that can corrode an older masonry flue. We inspect the existing flue, explain what we find, and install a correctly sized liner when one is called for.
How Manhattan Weather Wears Down Masonry
Winters here bring repeated freeze-thaw cycles, and nor'easters drive rain sideways into exposed brick. When water soaks into a chimney crown or mortar joint, it freezes, expands and loosens the masonry a little more each year. Hot, humid summers can bring out musty fireplace odors when a damp flue has no cap.
Rooftop chimneys that rise above neighboring buildings take the worst of the weather at the top of the stack. A cap or chase cover keeps out rain, debris and birds. A breathable waterproofing treatment helps the brick shed water without trapping moisture inside.

Dryer Vents and Air Ducts in Apartments and Townhouses
Dryer vents in apartments and townhouses often run a long way through walls or ceilings before they reach the outside, and lint collects along the entire route. According to the U.S. Fire Administration, failure to clean is the leading factor contributing to home clothes dryer fires. If your loads take longer to dry or the laundry area feels unusually hot, the vent probably needs cleaning.
For air ducts, we follow the EPA's guidance. Cleaning makes sense when there is substantial visible mold, signs of vermin, or excessive dust and debris coming from the vents. The EPA also says duct cleaning has not been shown to prevent health problems, so we won't claim that it does. We walk you through the process before we start, and we use chemical treatments only when there is a clear reason and you agree to them.
Inspections and Services We Provide
The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. A Level 1 inspection fits most homes where nothing has changed. A Level 2 inspection is the right choice when the home is sold, a new appliance goes in, or you switch fuels. A Level 3 inspection is for hidden hazards that can only be reached by opening part of the chimney or building.
