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 Repair Across Sunset Park
Chimney repair in Sunset Park runs $350 to $1,800 for most masonry and flashing work, with full rebuilds on century-old row-house stacks landing between $2,500 and $6,000 depending on flue access and liner condition. If you’re in Sunset Park, you likely live in an attached brick row house built before 1925, which means your chimney has a story, and it’s usually not a pretty one. Wendell Pike has been working on those stacks since 1999, and he’ll tell you straight what needs fixing and what can wait. Call (516) 289-9316 and we’ll send a sweep who knows the neighborhood.
Why Top Hat Chimney Is Sunset Park’s Preferred Chimney Repair Company
We’re the ones your neighbors call when a national chain sends a stranger who quotes $199 on the phone and $1,900 at the door. Sunset Park’s housing stock doesn’t tolerate guesswork. Those attached row houses on 4th and 5th Avenues, from the industrial blocks near the Brooklyn Army Terminal up to the residential streets around Sunset Park proper, share chimney stacks. One bad repair job can push carbon monoxide into someone else’s apartment. Wendell and his crew have been called back to fix work from companies that didn’t understand that. Ask anyone on your street.
The people who call us are mostly landlords managing two-to-four-unit conversions and homeowners who’ve lived in the same house since before the neighborhood got its name. We answer the phone around the clock. Not a call center. A live person, and plenty often Wendell himself. When you call (516) 289-9316, you’ll get a straight answer and a real arrival window, and if that window slips, we call you before you call us. Every job comes with our 90-Day Done Right Promise in writing. If it’s not right, one call brings the crew back at no charge.
Our Chimney Repair Services in Sunset Park
Mortar Repointing
Repointing in Sunset Park typically costs $450 to $1,200 depending on how many courses of mortar need raking and how much of the stack is accessible from the roof. The original lime mortar in those 1890s-to-1920s row houses was mixed soft, which is a blessing because it breathes, but a curse because it erodes. We match the mortar to the brick, not the other way around. On the west slope above the harbor, we recommend adding a mild water repellent to the mix because those southwest winds carry salt and moisture that eat standard joints faster than any other part of Brooklyn.

Spalling Brick Repair
Spalling runs $200 to $600 for a handful of bricks and $2,000 to $4,000 when an entire face needs to be cut out and replaced. We see it most on harbor-facing exterior walls and up near the crown, where rain saturates the brick and freeze-thaw cycles pop the face right off. If your bricks are shedding, don’t wait. The exposed interior brick is softer, and the damage compounds every winter. We’ll show you camera footage before we touch a brick, and you’ll get a plain-English verdict, no exceptions.

Chimney Waterproofing
Waterproofing runs $350 to $800 for a standard two-to-three-flue stack, and it’s one of the best values in this neighborhood. Sunset Park’s elevated ridge above New York Harbor means prevailing winds drive rain into mortar joints almost horizontally. We use breathable water repellents from Olympia Chimney, the kind that keep water out but let vapor escape from inside the flue. If you seal with the wrong product you trap moisture inside the brick and make spalling worse. We don’t.

Flashing Repair
Flashing repair around a chimney base costs $300 to $900, and bad flashing is the single most common source of ceiling leaks in Sunset Park row houses. Those steep-pitched roofs on the hipped rowhouse sections make flashing that much harder to get right. We fabricate new flashing from Copperfield stock, not the thin box-store aluminum that kinks and separates at the first freeze. A proper step-flashing installation, counter-flashed and sealed, will outlast the roof itself.

Common Chimney Repair Problems We See in Sunset Park Homes
- Cross-contamination between apartments. When a neighbor’s high-efficiency gas boiler vents into a shared flue that’s already compromised, the exhaust can spill into another unit. This is not a theoretical risk. We’ve tested and confirmed it on repair jobs along 4th and 5th Avenues, and it’s why a chimney repair here is often an emergency, not a cosmetic project.
- Collapsed terra-cotta flue tiles. The original flues in Sunset Park row houses were laid in segments, and after a century of heating, cooling, and the occasional former coal-burning era, those tiles shift, crack, and often collapse inward. You can’t see it from the street. A camera inspection shows you exactly what the flue looks like, and we don’t recommend liner work without one.
- Rapid spalling and mortar erosion on harbor-facing crowns. The west slope of Sunset Park sits directly above New York Harbor, and the persistent southwest wind carries salt moisture that chews through chimney crowns and mortar faster than inland Brooklyn. If your stack faces the water, your maintenance schedule is shorter than the guy’s up on the ridge.
- Gas boiler flue mismatch. Most of these stacks were built for coal fireplaces and re-lined at some point for oil, then switched to gas. The flues are oversized for modern high-efficiency gas boilers, which don’t produce enough draft heat to push moisture out. That moisture condenses inside the flue, eats the liner, and drips back down into the masonry. We fix it with properly sized insulated liners.

FAQs - Chimney Repair in Sunset Park
If your unit shares a flue with a neighbor, you share liability for that flue’s condition under NYC building and fire codes, and if a CO leak originates in a shared stack, it’s not always clear who pays. The practical answer is that the repair gets split among the units on the stack, but only if all parties agree. If a neighbor balks, the DOB can compel repairs when a registered boiler inspection flags the flue. The fastest path is to have us camera-inspect the flue and hand you footage and a written report so the conversation stops being about opinions and starts being about evidence. Call (516) 289-9316 and we’ll walk you through it.
Because these chimneys were built for coal in the 1890s through 1920s, converted to oil, then gas, and many were never properly re-lined for the fuel changes. The terra-cotta tiles are often cracked, offset, or collapsed, and the mortar has lost its binder to a century of freeze-thaw exposure on that harbor-facing slope. Repointing alone won’t fix a broken flue, and a broken flue is what actually matters. Your chimney can look fine from the street and be a hazard inside. That’s why we camera every flue before recommending anything.
Yes, it can, and it’s not cosmetic. Sunset Park sits on a glacial ridge above New York Harbor, and the southwest wind off the Upper Bay carries salt and moisture directly into the west-facing crowns and mortar. The salt crystallizes inside the pores of the brick and mortar, expanding and fracturing them faster than inland Brooklyn. The damage is structural. A cracked crown lets water into the stack, and freeze-thaw does the rest. Letting salt erosion go means you go from a $600 crown repair to a $4,000 rebuild. Call (516) 289-9316 for a free crown inspection.
No, you’re not responsible for chimney repair as a tenant. That’s the landlord’s obligation under the NYC Housing Maintenance Code and the warranty of habitability. You can and should report it, and if the landlord doesn’t act, you can file a complaint with 311 or HPD, and that complaint creates a paper trail that protects you. You can schedule an inspection yourself if you want documentation, and we’ll give you camera footage and a written report you can hand to your landlord. We do this regularly for Sunset Park tenants on 51st Street and near 5th Avenue. If your carbon monoxide detector is going off, call 911 first, then call us at (516) 289-9316.
You won’t know without a camera inspection. Gas boilers vent continuously at low temperature, and if your flue is oversized, which most original Sunset Park flues are, the exhaust doesn’t rise fast enough to stay warm. Moisture condenses inside the liner, dissolves it, and eventually the liner crumbles. You may notice white efflorescence on the chimney exterior, or a sulfur smell near the stack, or you may notice nothing at all. The only way to know for certain is to look. We’ll send a camera down your flue and show you the footage on the spot. Call (516) 289-9316 and we’ll schedule it.
