Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Repair Across Brooklyn
Chimney repair throughout Brooklyn means working on buildings most contractors will not touch: 120-year-old attached row houses, shared party-wall stacks, and flues that started life burning coal. We know these chimneys because we have climbed them in Park Slope, Carroll Gardens, Bed-Stuy, and the blocks between. When a Crown Heights boiler is venting into a clay-tile flue that has not been touched since the Eisenhower administration, the fix is rarely a tube of sealant. Call (516) 289-9316 and a live person answers. Wendell and his crew will come out, run the camera, and tell you what the chimney actually needs. That is the whole job.
Why Top Hat Chimney Is Brooklyn’s Preferred Chimney Repair Company
Top Hat Chimney has worked the same communities since 1999. Not a franchise that rotated in last spring. Wendell Pike puts his name and license number on every job, and he runs into you again on Saturday. In Brooklyn that matters more than in most places, because the chimney you are repairing is often attached to a chimney your neighbor owns too. You need someone who understands how a shared stack in Bed-Stuy works, how flashing on a Fort Greene parapet ties into two roofs at once, and why a Park Slope brownstone crowns crack the way they do. We are that crew.
Ask anyone on your street. Brooklyn homeowners call us because the number on the phone is the number on the invoice. No bait price, no door-switch. Every quote is delivered upfront before a single tool comes off the truck, and every completed job carries the 90-Day Done Right Promise in writing. If the work is not right, one call brings Wendell back at no additional charge. Our phones are staffed by a live person twenty-four hours a day, seven days a week. Sometimes it is Wendell himself picking up.
Our Chimney Repair crews understand Brooklyn’s building stock in a way a national call center cannot. When you describe a chimney problem in a Williamsburg walk-up or a Ditmas Park Victorian, the person doing the work has already been on that block. That is the difference between troubleshooting over the phone and actually knowing what the roof looks like.
Our Chimney Repair Services in Brooklyn
Mortar Repointing
Brooklyn’s brick stacks are old enough that the original lime mortar is often gone, replaced by whatever patching compound a previous owner had in the basement. Salt-laden air off Upper New York Bay eats exposed mortar faster than inland markets, so repointing done without grinding out loose material simply fails within two winters. In neighborhoods like Bushwick and East Flatbush, we routinely open joints that look fine from the street and find crumbling powder an inch and a half deep. We remove it, pack the joint with fresh mortar matched to the building’s age and brick color, and do not caulk over rot.
Spalling Brick Repair
Spalling brick means water is getting into the face of the brick and freezing. Brooklyn’s repeated freeze-thaw cycles make this a particular problem on south- and west-facing chimney faces toward the harbor, the side that takes the worst weather all winter. A spalled brick is not cosmetic; it is structural. We cut out the damaged units, bed replacements into fresh mortar, and then address the water entry that caused the freeze damage in the first place. On a Carroll Gardens brownstone, that usually means fixing the crown and flashing before the next winter hits.
Chimney Waterproofing
You cannot waterproof your way out of missing mortar, but on older Brooklyn masonry, a breathable siloxane treatment after repointing helps slow salt absorption from ocean air and freeze-thaw spalling. The key word is breathable. Trapping moisture inside a 130-year-old brick stack makes things worse, not better. We apply the treatment only after the masonry work is done and the excess water has dried, and we explain exactly what it will and will not do before any product touches the brick.
Flashing Repair
Flashing on Brooklyn row-house chimneys is often tied into a neighbor’s roof or parapet. A leak that shows up in your top-floor ceiling may actually start at the shared counter-flashing, and any repair that only addresses your side of the stack will keep leaking into both properties. We pull the old flashing, inspect the full intersection where masonry meets roof membrane, and install new step and counter-flashing that handles both sides of the shared condition. This is not a caulk-and-go job. It is a get-it-right-once job.
When the damage is beyond repair, our Chimney Repair in Brooklyn crews also handle full chimney rebuilding from the roofline up, matching brick and mortar to the existing street-facing masonry. Some of these stacks have stood since the 1880s. When properly rebuilt, they can stand another century.

Common Chimney Repair Problems We See in Brooklyn Homes
This is what our cameras actually find on Brooklyn roofs, week after week. It is not a generic list.
- Clay-tile flues built for coal that were never relined. Brooklyn’s row houses burned coal when they were built, then switched to oil, then gas. Flues originally sized for coal are too large for today’s high-efficiency boilers, and the acidic condensate from gas exhaust eats the mortar between tiles. By the time a homeowner notices a draft problem, the flue is often spalling from the inside. A camera inspection shows this in minutes.
- Boarded-over fireplaces reopened during renovating. In Bed-Stuy, Bushwick, and East Flatbush, owners who bought recently renovated brownstones often find the “charming original fireplace” was plastered over in the 1950s when oil heat was installed. The flue behind it has not been swept or inspected in sixty or more years and is frequently packed with collapsed liner fragments, bird nests, and decades of debris. A Level 2 camera inspection is not optional on these. It is the bare minimum before a fire is lit.
- Shared party-wall stacks with access and liability problems. When two brownstones share a single masonry chimney, repair decisions cannot be made unilaterally. A stack in Fort Greene or Carroll Gardens with three flues may serve two dwellings across two properties. Figuring out who pays for what, who provides roof access, and which contractor handles both sides is not something suburban chimney companies deal with. We do.
- Salt-driven mortar erosion near the harbor. Red Hook, Sunset Park, and any block close enough to feel the harbor air lose pointing mortar faster than neighborhoods further inland. Joints that look intact to the naked eye are often hollowed behind the surface, and water intrusion accelerates spalling through every freeze-thaw cycle. This is why regular chimney maintenance in Brooklyn is not a suggestion. It is the cheapest way to avoid a rebuild later.

FAQs - Chimney Repair in Brooklyn
No. Do not light anything in a fireplace that was boarded over for sixty years until a camera has been run through the flue. In Bed-Stuy, Bushwick, and East Flatbush, we routinely find these flues packed with collapsed clay tile, old bird nests, and passive debris fall from decades of neglect. The damper is usually seized with third-degree creosote glaze. Put a fire in that and you are gambling with a chimney fire or carbon monoxide entering the house. We run a Level 2 camera inspection, remove the debris, and tell you whether the flue can be safely used. If it needs relining, you will see the footage. Call (516) 289-9316 and we will schedule the inspection before heating season.
Because the previous repair was mortar over a moving crack, not a proper crown rebuild with expansion space. Brooklyn’s freeze-thaw cycles are relentless, especially on south- and west-facing roofs near the harbor. Water gets into hairline cracks, freezes, expands, and reopens the same crack year after year. The fix is a poured concrete crown with the right overhang, drip edge, and expansion joint, not another smear of sealant. When you call, we will show you what the old crown looks like from the roof and what a properly built one looks like. You will understand the difference before you spend a dollar.
That depends on the deed, the building line, and what the stack actually serves. In shared party-wall conditions common in Park Slope, Fort Greene, and Carroll Gardens, a single masonry stack may serve flues for two dwellings across two properties. The repointing or rebuilding cost is often shared, but not always, and sometimes one owner’s flue is the issue while the other owner’s side of the stack is fine. We identify exactly which flues are involved, what the masonry condition looks like across the whole stack, and what each property actually needs. Then you and your neighbor can have an informed conversation instead of fighting over a guess. But the work has to be coordinated; a one-side repair on a shared stack simply does not hold.
Ask for the camera footage. If a company tells you a full reline is needed and cannot show you video of the flue interior, that is not a diagnosis. That is a sales pitch. In Brooklyn’s older housing stock, sometimes a full reline is genuinely necessary, especially when original clay tile has cracked from years of coal-to-gas conversion and acidic condensate. But sometimes the flue needs a cleaning and a spot repair, and nothing more. We run a Level 2 camera on every inspection, show you the footage in plain view, and hand you a written report. We have talked more Brooklyn homeowners out of unnecessary relines than we can count, and we will do the same for you. A free second opinion on any competing written estimate is a standing offer. Call (516) 289-9316.
What is different is the shared roof geometry of Brooklyn’s row houses. Most flashing leaks on these buildings are not the fault of the flashing itself. The counter-flashing is tied into a neighbor’s roof or parapet, and when only your side is resealed, the water still finds the gap between the two properties. A proper repair in Brooklyn means addressing the full intersection where masonry meets roof membrane on both sides of the shared condition. It also means checking whether the crown is directing water down the face of the chimney instead of shedding it. We fix the whole water path, not just the visible seam. That is why our flashing repairs on Fort Greene and Carroll Gardens brownstones outlast the previous two reseal jobs put together.
