The short answer
EmberGuard Chimney Sweep repairs crowns, flashing, mortar joints, caps, dampers and flue liners on SoHo rowhouses, lofts and pre-war apartment buildings from our office on Broome St. Every repair starts with an inspection so we fix the actual cause. Work on boiler chimneys is best planned outside the October 1 to May 31 heat season.
EmberGuard Chimney Sweep works out of 489 Broome St, so chimney repair in SoHo is close-to-home work for us. Chimneys in this neighborhood serve fireplaces in loft conversions, boiler flues in pre-war apartment buildings, and older masonry stacks on rowhouses and brownstones. Many have been through decades of freezing winters, summer heat and city grime. Our certified technicians inspect first, explain what they find in plain terms, and repair what actually needs it, from a cracked crown to a deteriorated flue liner.
Chimney Problems We See in SoHo Buildings
Chimneys here take a beating. Masonry stacks rise above flat roofs, where they face wind, rain and repeated freezing and thawing. Water causes most of the damage we repair. Once moisture gets into brick and mortar, it expands in cold weather, pushes joints apart and works its way down into the building.
- Cracked or crumbling crowns that let water run straight into the masonry
- Loose or failed flashing where the chimney meets the roof, a common source of stains on ceilings and walls
- Eroded mortar joints that need repointing before bricks start to shift or spall
- Damaged or missing chimney caps that let in rain, debris and animals
- Cracked clay tile liners or corroded metal liners inside the flue
- Rusted or stuck dampers in older fireplaces
- Deteriorated smoke chambers above the firebox

Why Every Repair Starts With an Inspection
The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year. An inspection is also the right starting point for any repair. A stain on the ceiling could come from flashing, a cracked crown or porous brick, and fixing the wrong one wastes your time and money.
Chimney professionals use three inspection levels. A Level 1 inspection fits when nothing about the system has changed. A Level 2 is called for when something does change, such as a new appliance or a switch of fuel, or when the home is sold. A Level 3 is for cases where a hidden hazard can only be reached by opening part of the chimney or building. Before any work begins, we'll tell you which level your situation calls for and why.
Oil-to-Gas Conversions and New Flue Liners
Many pre-war apartment buildings in the area have switched, or plan to switch, from oil-fired boilers to gas. 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 because gas exhaust produces acidic condensate that can corrode a masonry flue.
We inspect the existing flue, check its size and condition against the new equipment, and recommend a liner when one is needed. Bringing us in early, alongside your boiler contractor, keeps the chimney from becoming a last-minute holdup on the conversion.

Planning Repairs Around 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. If your chimney vents a central boiler, timing matters. Liner work, flue repairs and major masonry on a boiler chimney are easier to schedule outside heat season, when taking the heating system offline won't leave tenants without heat.
For fireplace chimneys in lofts and rowhouses, late spring and summer are also a practical time to fix crowns, flashing and mortar. That way the chimney is sound before you light the first fire in the fall.
What to Expect From a Repair Visit
Our certified technicians check the chimney from the roof and from inside, and they photograph what they find so you can see it yourself. You'll get a clear explanation of what's wrong, what's urgent and what can wait.
- Inspection of the crown, cap, flashing, masonry, liner, damper and smoke chamber
- Photos and a plain-language explanation of each problem
- A written scope of work before repairs begin
- Protection for floors and furniture during interior work
- Cleanup when the job is done
