The short answer
EmberGuard repairs chimney masonry, crowns, caps, flashing, dampers and flue liners for homes and buildings in Hudson Square, working from our Broome St office. We inspect first to find the real cause, then plan repairs around building access and New York City's heat season.
EmberGuard Chimney Sweep works out of our office at 489 Broome St in Hudson Square, so chimney repair calls in 10012 and the surrounding area are close to home for us. Hudson Square's housing is a mix of pre-war apartment buildings, converted loft buildings and older rowhouses. Many of them have masonry chimneys that have carried wood smoke, oil exhaust or gas exhaust for a long time. Repairing those chimneys often means tall flues, shared roofs and access that has to be arranged with a building manager or board. Our certified technicians start by finding out what is actually wrong. They explain it in plain terms and repair what needs fixing, without selling you work you don't need.
Chimney problems we see in Hudson Square buildings
Older Manhattan chimneys take a beating from freeze-thaw cycles, wind at roof height and years of exhaust. Damage usually starts small at the top of the chimney, where few people look. It shows up later as a water stain on a top-floor ceiling, loose brick on the roof, or a draft problem in a fireplace or boiler flue.
These are the repairs we handle most often:
- Cracked, spalling or loose brick on the chimney stack
- Eroded mortar joints that need repointing
- Cracked or crumbling chimney crowns that let water into the masonry
- Missing or damaged chimney caps that let in rain, debris and animals
- Failed flashing where the chimney meets the roof, a common source of leaks
- Cracked clay tile liners or corroded metal liners
- Stuck, rusted or poorly sealing fireplace dampers

Oil-to-gas conversions and flue liners
Many pre-war buildings in this part of Manhattan were built around oil-fired boilers. When a New York City building converts its boiler from oil to gas, the chimney has to be evaluated as part of the work. A new liner is often needed. Gas exhaust produces acidic condensate, and that condensate can corrode a masonry flue that was never designed to handle it.
If your building is planning a conversion, or has already converted and you are seeing deteriorating masonry, staining or debris at the base of the flue, we can evaluate the chimney. We'll tell you whether the existing liner is suitable. When a relining is needed, we size and install a liner that matches the new appliance.
Finding the cause before we repair
The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. Chimney professionals use three inspection levels, and the right one depends on your situation.
A Level 1 inspection fits when nothing about the system has changed. A Level 2 inspection is called for when the system changes, such as a new appliance or a switch of fuel, or when the home is sold. A Level 3 inspection is used when a hidden hazard can only be reached by opening part of the chimney or building. Most repair visits in Hudson Square start with a Level 1 or Level 2 inspection, often with a camera run through the flue. That way we can show you the damage before recommending a fix.
Time for your annual chimney check?
Planning repairs around heat season
New York City's heat season runs from October 1 through May 31. During that period, building owners must keep apartments heated to the city's minimum temperatures. A boiler flue that needs repair in the middle of winter can put a building in a tough spot, because the heating system may have to stay in service.
When possible, we recommend scheduling inspections and major repairs like relining or rebuilding a crown in late spring or summer. If a problem turns up during heat season, we'll talk through what can be done safely and how to keep the work as short as possible.
Working in Hudson Square and nearby neighborhoods
Chimney repair in a dense neighborhood is as much about logistics as masonry. We coordinate roof access with superintendents, managing agents and co-op or condo boards. We protect interior spaces and shared hallways, and we keep debris contained on rooftops close to neighboring buildings.
Besides Hudson Square, we regularly work in SoHo, Little Italy, Tribeca, Civic Center and Greenwich Village. The housing in these neighborhoods is similar, so the chimney issues are similar too: older masonry, tall shared stacks and heating systems that have changed over the years.
