The short answer
Nexora Chimney Services provides chimney sweeping, inspections, repairs, liner installation, and dryer vent and air duct cleaning in Two Bridges, Manhattan. Our technicians come from our nearby Gramercy office and work on the walk-ups, pre-war apartment buildings, and rowhouses common to the neighborhood.
Nexora Chimney Services works in Two Bridges from our office in Gramercy, about 2 miles north. The neighborhood is mostly apartment buildings: older walk-ups, pre-war apartment buildings, and larger multi-unit buildings, with a few rowhouses mixed in. That means the chimney and vent work here usually involves shared boiler flues, building-wide exhaust systems, and individual apartments with fireplaces or dryers. Our certified technicians sweep, inspect, repair, and reline chimneys, and we clean dryer vents and air ducts for homeowners, co-op and condo boards, and building owners.
What We See in Two Bridges Buildings
Most chimneys in Two Bridges serve boilers, not fireplaces. In older masonry buildings, one tall flue often carries exhaust from a central heating plant for the whole building. Those flues run hot for most of the year, and they collect soot, scale, and crumbling mortar over time. When a flue is partly blocked or its liner has failed, exhaust can back up into the boiler room or living spaces.
Some apartments and rowhouses still have working or decorative fireplaces. These need the same attention as any wood-burning system: a sound firebox, a damper that opens and seals, and a clear flue with a cap on top. We also clean the dryer vents and air ducts that run through these buildings, which are often long, shared, or hard to reach.
Annual Inspections Before Heat Season
New York City's heat season runs from October 1 through May 31. During those months, building owners must keep apartments heated to the city's minimum temperatures, so a boiler that has to shut down because of a chimney problem becomes an urgent issue. Late summer and early fall are the best times to have the flue checked.
The NFPA 211 standard calls for chimneys, fireplaces, and vents to be inspected once a year. We follow its three inspection levels:
- Level 1: a standard check when nothing about the system has changed.
- Level 2: needed when the system changes, such as a new boiler or a switch in fuel, or when the property is sold.
- Level 3: used when a hidden hazard can only be reached by opening part of the chimney or building.
Oil-to-Gas Conversions and Chimney Liners
Many Two Bridges buildings have converted, or are planning to convert, their boilers from oil to gas. When a New York City building makes that switch, the chimney has to be evaluated as part of the job. A new liner is often required because gas exhaust produces acidic condensate that can eat away at an unlined or poorly lined masonry flue.
We inspect the existing flue, explain what we find, and install a properly sized chimney liner when one is needed. If the masonry above the roof has deteriorated too far, we can repair or rebuild the affected section.

Weather, Water, and Masonry
Manhattan winters bring repeated freezing and thawing. Water soaks into brick and mortar, freezes, expands, and slowly breaks the masonry apart. Strong storms and wind-driven rain add to the problem, especially on tall chimneys exposed on rooftops. Humid summers can also leave fireplaces smelling damp and musty.
Our work to keep water out includes:
- Chimney caps and chase covers to keep rain, debris, and animals out of the flue
- Waterproofing treatments for brick and mortar
- Crown and mortar joint repair
- Fireplace and damper repair to stop drafts and leaks
Dryer Vent and Air Duct Cleaning
Apartment dryer vents tend to be long, have several bends, and sometimes tie into shared building exhaust. Lint builds up quickly in runs like these. According to the U.S. Fire Administration, failure to clean is the leading factor contributing to clothes dryer fires in homes. If drying takes longer than it used to or the laundry area gets unusually hot, have the vent 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. We will tell you plainly whether your ducts need cleaning, and we do not push chemical treatments.
