The short answer
All Star Chimney Sweep repairs chimneys on brownstones, rowhouses and pre-war buildings in Carroll Gardens from our office on Henry St. We inspect first, then repair masonry, crowns, flashing, caps, dampers and flue liners. We also evaluate and reline flues for oil-to-gas boiler conversions.
Most chimneys in Carroll Gardens belong to older masonry buildings: brownstones, brick rowhouses and pre-war apartment buildings. They tend to wear out in predictable ways. Mortar washes out of the joints, crowns crack, flashing pulls away from the roof, and flue liners deteriorate after decades of heat and moisture. All Star Chimney Sweep handles chimney repair from our office at 543 Henry St, so this is our own neighborhood. Our certified technicians find out what's actually wrong, explain it in plain terms, and fix the cause instead of patching the symptom.
What Usually Goes Wrong with Carroll Gardens Chimneys
Brick chimneys on older Brooklyn homes take a beating from the weather. Water causes most of the damage. It soaks into porous brick and aging mortar, freezes in winter, and expands, which slowly breaks the masonry apart from the inside. By the time you notice a stain on a ceiling or a piece of brick on the roof, the problem has usually been building for a while.
In attached homes, chimney stacks often sit along a shared wall or rise above a flat roof. A leak can show up well away from where the water actually gets in. We trace the water path before we recommend any repair, so you aren't paying to fix the wrong spot.
- Crumbling or missing mortar joints, repaired by repointing
- Cracked or spalling brick, where the face of the brick flakes away
- Cracked chimney crowns that let water into the top of the stack
- Failed or loose flashing where the chimney meets the roof
- Damaged or missing caps that let in rain, debris and animals
- Cracked, gapped or deteriorated flue tiles
- Dampers that stick, rust or no longer seal
We Inspect Before We Repair
Good repair work starts with knowing the condition of the whole system. The NFPA 211 standard calls for chimneys, fireplaces and vents to be inspected once a year, and chimney professionals use three inspection levels. A Level 1 inspection fits when nothing about the system has changed.
A Level 2 inspection applies when the system changes, such as a new appliance or a switch of fuel, or when the home is sold. If you're buying or selling a home in the neighborhood, this is the level that applies. A Level 3 inspection is for cases where a hidden hazard has to be reached by opening part of the chimney or building.
We'll tell you which level fits your situation and why. Then we'll walk you through what we found and what needs attention now, and what can wait.
Flue Liners and Oil-to-Gas Conversions
Many older buildings in the area were built for coal or oil heat. 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 evaluate the existing flue, check whether it suits the new appliance, and install a liner when one is needed. We're glad to coordinate with your heating contractor so the chimney work fits the conversion schedule.
A damaged liner is worth fixing even if you aren't converting. Cracks and gaps in the flue can let heat and exhaust reach parts of the building they shouldn't.

Planning Repairs Around the Heating 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. If you own a multi-unit building, a chimney problem that takes the boiler offline in January is much harder to deal with than one fixed in summer.
Late spring through early fall is usually the easiest time for masonry and liner work. Mild weather is better for mortar, and taking the heating system out of service briefly doesn't leave anyone in the cold. If an inspection turns up a problem in winter, we'll help you sort out what needs to be done right away and what can be scheduled for the warmer months.
