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.
Fast, Reliable Chimney Liner & Rebuild Across Flatbush
A chimney liner replacement or partial rebuild in Flatbush typically runs $2,800-$7,500 depending on flue size, liner material, crown work, and access. Most jobs take one to two days on-site, and we schedule them around your heating season so you’re never left without heat. If you own one of the landmarked Victorians off Rugby Road, Albemarle Road, or Cortelyou Road, you already know the masonry needs a careful hand. Call (516) 289-9316 and Wendell or one of his crew will walk you through what your chimney actually needs, not what a sales script says it needs.
Why Top Hat Chimney Is Flatbush’s Preferred Chimney Liner & Rebuild Company
Wendell Pike started Top Hat Chimney in 1999 and has spent more than two decades inside the exact kind of chimneys that line Flatbush’s streets. The homes here aren’t like the newer construction in neighboring Brooklyn neighborhoods. They’re century-old masonry stacks with clay-tile flues that were built for coal, converted for oil, and never properly relined. That’s a specific set of problems, and it demands a specific kind of experience.
Our Chimney Liner & Rebuild crew has rebuilt stacks from Ditmas Park to Prospect Park South, and the work holds up because we scope every flue before we quote a dollar. You see the camera footage. You get a plain-English verdict. No “trust us” games. The phone rings to a live person around the clock, and when you call about your Flatbush chimney, you’re talking to someone who knows the difference between a Rugby Road Victorian and a Cortelyou Road semi-detached.
Every job carries the 90-Day Done Right Promise in writing. If something isn’t right after we leave, one call brings us back at no charge. That’s the whole promise. Ask anyone on your street who’s had chimney work done poorly by someone else, then compare it to how we handle it.
Our Chimney Liner & Rebuild Services in Flatbush
Stainless Steel Liner
For Flatbush homes with oil-fired boilers, a properly sized stainless steel liner is often the single best fix for an oversized coal-era flue. We install DuraFlex stainless systems that match the BTU load of your actual appliance, not the 1910 coal burner that used to be there. That means better draft, less sticky oily-soot buildup, and a flue that actually handles the sulfurous condensate from modern oil heat without crumbling.

Flexible Liner
When a Flatbush chimney has a slight offset or a tight attic chase, a flexible liner makes sense. We install Copperfield and DuraFlex flex liners with proper insulation where code calls for it. The most important part isn’t the liner itself; it’s whether the existing masonry can support the new system. In Flatbush, where crowns are spalled and mortar joints are hungry for water, we’ll tell you plainly when a flex liner alone is enough and when it’s a band-aid on a stack that needs more.

Liner Replacement
Most Flatbush homes with original clay-tile liners will need a replacement at some point, especially where an oil boiler has been running for decades. Cracks from thermal stress let flue gases into wall cavities. In a house with balloon framing, that can mean carbon monoxide in living spaces. We scope the flue, show you the cracks on camera, and replace the liner system the same way we’d do it on our own house.

Partial Rebuild
A partial rebuild in Flatbush usually means the top five to ten courses of brick, a new crown, and often a new damper assembly. Brooklyn’s freeze-thaw cycles around 32°F are brutal on century-old crowns. If you walk out to the sidewalk and look up at your chimney, and the top looks like it’s shedding brick skin, that’s the start of a partial rebuild. Catching it before water works its way down into the flue saves you thousands.

Common Chimney Liner & Rebuild Problems We See in Flatbush Homes
- Oversized coal-era flues starving modern oil burners for draft. The original flue opening was sized for a coal fire with a wide-open damper, not a sealed oil boiler. That mismatch creates chronic underdraft, heavy soot accumulation, and sulfurous condensate that eats clay tiles from the inside out. A camera scope will show the sticky black coating that tells you this is happening.
- Freeze-thaw spalling at the crown and upper courses. Flatbush sits right at the 32°F line all winter. Water seeps into a hairline crack, freezes, expands, and by March the crown is shedding chunks. We see this every spring on the exposed chimneys of the freestanding Victorians around Prospect Park South and Ditmas Park.
- Cracked clay-tile liners from coal-to-oil conversion. When these homes switched from coal to oil around the mid-20th century, the original clay tiles often weren’t replaced to match the new appliance’s heat output. Decades of oil-burner heat cycling has left those tiles cracked and sometimes collapsed. That’s a carbon monoxide path into the house, not just a draft issue.
- Two-flue stacks where one flue was abandoned badly. Many Flatbush chimneys carry two or more flues: one live oil flue and one old fireplace flue that was capped off without proper sealing. The dead flue still holds moisture against the live one, accelerating deterioration on the side you can’t see from the ground. We find this constantly on the Rugby Road and Albemarle Road blocks.
Pricing for Chimney Liner & Rebuild in Flatbush, NY
A stainless steel liner installation in Flatbush typically runs $2,800-$4,500 for a standard one-story or two-story run, depending on flue diameter and whether insulation is required. Liner replacement with a full crown rebuild and minor masonry work lands in the $4,500-$6,500 range. A full chimney rebuild, which often means taking down and rebuilding the entire stack above the roofline, starts around $7,000 and goes up from there based on height and access. The landmarked homes with steep slate roofs and tight side yards push costs higher because of staging and safety setup. Call (516) 289-9316 for a free estimate with camera documentation.

FAQs - Chimney Liner & Rebuild in Flatbush
Water gets into hairline cracks in the crown and mortar joints, freezes when the temperature drops below 32°F, and expands with enough force to split brick and crack clay tiles. Flatbush sees repeated oscillation around that freezing point all winter, so the damage compounds faster than in a city that stays consistently cold. The fix is a proper crown, sound mortar, and often a stainless steel liner that doesn’t care about the moisture. Call (516) 289-9316 for a free camera inspection and a quote on what your chimney actually needs.
Because the original coal-era flues are oversized for modern oil burners, which causes underdraft and condensing flue gases that eat clay tiles. A correctly sized stainless steel liner restores the draft and protects the masonry from further damage. It’s the right fix for most Flatbush houses with original chimneys. Call (516) 289-9316 and we’ll scope it and show you whether a liner is warranted or whether your current flue can stay as-is.
Yes. We regularly reline a single flue in a two- or three-flue stack while leaving the other flues alone, as long as the masonry between them is intact. If the common wall between flues has failed, we’ll tell you that too, with camera footage of what we found. Call (516) 289-9316 for a free estimate.
A full rebuild means taking the stack down to the roofline or further, rebuilding the masonry with proper mortar, installing a new liner system sized for the current appliances, and pouring a new crown with proper overhang and drip edge. For a Flatbush Victorian with a tall two-story stack, that’s a two-to-three-day job with scaffolding and careful staging around the slate roof. The 90-Day Done Right Promise applies. Call (516) 289-9316 for a detailed scope and written quote.
You generally can’t, not with certainty. You might see flaking tile at the cleanout, hear a hollow sound when the boiler kicks on, or find brown staining on interior walls near the chimney. Those are warning signs, but the only way to know for sure is a camera scope of the flue. We include that in every liner and rebuild estimate, and you watch the footage with us. Call (516) 289-9316 to schedule a scope.
