The short answer
EmberGuard Chimney Sweep repairs chimney masonry, crowns, flashing, caps, dampers, and flue liners in Two Bridges and nearby Lower Manhattan neighborhoods. We inspect first, explain what we find, and recommend only the repairs the chimney needs. Spring and late summer are good times to schedule, before the city's heat season starts on October 1.
Two Bridges sits about a mile southeast of our Manhattan office, so our crews can reach the neighborhood without a long trip across town. The housing here is a mix of older walk-up buildings, pre-war apartment buildings, rowhouses, and larger residential buildings, and many of their chimneys and flues have been in service for decades. EmberGuard Chimney Sweep repairs masonry chimneys, crowns, flashing, caps, dampers, and flue liners for homeowners, co-op and condo boards, and small building owners. Our certified technicians first find out what is actually wrong, then explain the repair in plain terms before any work begins.
Why Two Bridges Chimneys Wear Out
Most chimneys in Two Bridges are brick or block, and many serve boilers rather than fireplaces. They stand on exposed rooftops, take years of rain, wind, and freeze-thaw cycles, and carry exhaust that slowly breaks down mortar and flue tile from the inside. Damage usually starts small, like a cracked crown or a loose cap, and grows as water gets in.
In older buildings, it is common to find chimneys that have been patched several times with different materials. Part of our job is to sort out which earlier repairs are holding up and which are hiding a bigger problem.

Common Chimney Repairs We Handle
These are the problems we see most often on rowhouses and apartment buildings in the area:
- Repointing: replacing cracked or missing mortar joints so water stops working into the brick
- Crown repair or rebuilding: fixing the concrete or mortar cap on top of the chimney that sheds rain
- Flashing repair: resealing the joint where the chimney meets the roof to stop leaks into top-floor units
- Chimney caps and screens: keeping out rain, debris, and birds or other animals
- Spalling brick replacement: removing brick faces that have flaked or popped off from trapped moisture
- Damper repair or replacement for fireplaces that won't open, close, or seal
- Flue liner repair and relining when tiles are cracked or the liner no longer fits the appliance
Oil-to-Gas Conversions and Chimney Liners
Many Lower Manhattan buildings have switched their boilers from oil to gas. When a New York City building converts from oil to gas, the chimney has to be evaluated as part of the work. A new liner is often needed, because gas exhaust produces acidic condensate that can corrode a masonry flue that was built for oil.
If your building is planning a conversion, bring us in early. We can inspect the flue, tell you whether the existing liner can stay or needs replacing, and coordinate timing with your heating contractor so the chimney work doesn't hold up the boiler job.

Inspections, Repair Timing, and Heat Season
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 called for when the system changes, such as a new appliance or a fuel switch, or when the home is sold. A Level 3 inspection is used when a suspected hidden hazard 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 during that time. Taking a boiler chimney out of service in January creates real problems for tenants and owners. For larger repairs, we recommend scheduling in late spring or summer so the work is finished well before October.
What to Expect From a Repair Visit
We start with an inspection of the chimney exterior, the roof connection, and the flue, using a camera when we need to see inside. You get a clear explanation of what we found, photos where they help, and a written description of the recommended repair.
Once you approve the work, we protect the work area, make the repair, and clean up afterward. For buildings with a board or managing agent, we can share our findings in a form that is easy to pass along. We also serve nearby Chinatown, the Lower East Side, Tribeca, Civic Center, and SoHo.
