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 Cap & Crown Across Brooklyn
A chimney cap or crown that’s failing on a Brooklyn row house doesn’t just leak water into your flue. On the attached blocks of Bed-Stuy, Park Slope, and Carroll Gardens, a cracked crown on a shared stack can send water into your neighbor’s liner, and a rusted-through cap on their side can fill your flue with rain and debris. We’ve worked these blocks since 1999, and Wendell and his crew know how to fix the cap and crown problems that Brooklyn’s century-old masonry actually has. Call (516) 289-9316 and you’ll get a straight answer and a flat price before a single tool comes off the truck.
Why Top Hat Chimney Is Brooklyn’s Preferred Chimney Cap & Crown Company
We’re not a franchise that rotated into the borough last spring. Top Hat Chimney was founded in 1999 by Wendell Pike, and Wendell puts his name and license number on every job we do. When you call, a live person answers, around the clock. It may well be Wendell picking up. When the sweep shows up at your door for our Chimney Cleaning & Sweep in Brooklyn, he’s background-checked, uniformed, and he gives you a real arrival window, and we call if that window slips.
What Brooklyn homeowners keep telling us is that they’ve been burned by a national outfit that quoted one price on the phone and another at the door. We don’t play that. Upfront pricing, every time. The number you hear on the phone is the number on the invoice, and every job is backed by our 90-Day Done Right Promise in writing. If it’s not right, one call brings us back.
We know the housing stock here. We know that a brownstone flue in Fort Greene wasn’t built for a modern gas boiler, and we know that a cap sized for a coal flue in Crown Heights is often too small for the converted vent it now serves. That local knowledge changes how we diagnose and how we quote. Ask anyone on your street.
Our Chimney Cap & Crown Services in Brooklyn
We handle the full range of Chimney Cap & Crown work across the borough. Here’s what that looks like on the ground in Brooklyn:
Cap Installation
A good cap keeps rain, snow, and pigeons out of the flue, and directs water away from the crown. On Brooklyn row houses, we size the cap to the actual vent, not to whatever was clamped on decades ago. If your flue was converted from coal to oil to gas over the years, that old cap may be wrong for the appliance it now serves. We install stainless and copper caps, including multi-flue designs for shared stacks.

Cap Replacement
Salt-laden harbor air chews through galvanized caps in a decade or less, especially on the south and west faces facing Upper New York Bay. If your current cap is rusted through, warped, or pulled loose by wind, replacing it now is cheaper than relining a flue that’s been getting rained into for years. We’ll show you the old cap when we take it off, and you’ll see exactly why it failed.

Crown Repair
The crown is the concrete or mortar slab that seals the top of the chimney around the flue. On Brooklyn’s 90 to 140 year old brownstones, crowns crack from freeze-thaw cycles, and once water gets into the mortar bed, spalling starts and the top courses of brick loosen. Our Chimney Repair in Brooklyn includes proper slope and overhang, and we repoint the top courses when the bricks are sound enough to save. On shared row-house stacks, we coordinate with the adjacent owner so the repair spans the property line cleanly.

Crown Coating
A crown that’s structurally intact but weathered can be sealed with a flexible crown coat that bridges hairline cracks and keeps water out for another decade or more. On a Park Slope brownstone where the crown is original and still holding its shape but showing surface cracks, coating is often the right call, and it’s a fraction of the cost of a full crown rebuild. We’ll tell you plainly if coating is enough or if the crown needs real repair work.

Trusted Brands We Service in Brooklyn
We install and service Chimney Cap & Crown products from brands we trust on Brooklyn rooftops: Gelco, Olympia Chimney, Famco, and Copperfield. We don’t push a brand because it’s on the truck; we recommend the cap or crown product that actually suits the flue and the exposure. When you need a replacement part, we carry common sizes locally, so a straightforward cap swap doesn’t drag into a two-week wait. Custom copper caps for odd flue configurations are sourced to spec, and we’ll give you an honest timeline before we order.
Common Chimney Cap & Crown Problems We See in Brooklyn Homes
- Shared-stack water damage. On attached row-house blocks from Bed-Stuy to Carroll Gardens, a single masonry stack often carries flues from two or more buildings. A missing cap on one owner’s flue admits water that damages a neighbor’s liner, so a simple cap replacement on your side can become a two-owner coordination job. We handle that coordination, and we document everything with camera footage.
- Harbor-air corrosion. Brooklyn’s peninsula sits between Upper New York Bay, the East River, and the Atlantic-facing shore, and salt-laden air accelerates metal cap corrosion faster than inland New York markets. Even galvanized caps that would last 20 years upstate can be rusted through in 8 to 12 years here, especially on south and west facing stacks.
- Freeze-thaw crown failure. Repeated winter freeze-thaw cycles force water into hairline crown cracks, and each cycle widens them. After a few Brooklyn winters, a hairline crack becomes a channel, and water reaches the mortar bed. That’s when spalling starts and the top courses of a century-old shared stack begin to loosen.
- Undersized caps on converted coal flues. Most Brooklyn row houses were built for coal, converted to oil, and later switched to gas. The original flue openings are often much larger than what a modern boiler vent needs, and an old cap sized for the coal-era opening can trap debris and block draft. The “charming original fireplace” in a newly renovated Crown Heights parlor is often venting through a flue that hasn’t been properly sized since before Eisenhower.
Pricing for Chimney Cap & Crown in Brooklyn, NY
A straightforward cap replacement on a Brooklyn row house typically runs $350-$650, depending on the flue size, cap material, and roof access.

FAQs - Chimney Cap & Crown in Brooklyn
In most cases, only the portion of the stack serving your flue needs work, but if the crown or cap spans both sides of the property line, we coordinate directly with the adjacent owner so the repair is done right across the full stack. We’ve done this on shared Bed-Stuy stacks for years, and we document every step with camera footage so both owners can see exactly what was found and what we did. Call (516) 289-9316 and we’ll explain what’s involved on your specific block; estimates are free.
Brooklyn’s position on a peninsula surrounded by Upper New York Bay, the East River, and the Atlantic-facing south shore means salt-laden air accelerates corrosion on metal caps, especially on south- and west-facing chimney faces that take the heaviest weather-driven exposure. Galvanized caps that last two decades inland often rust through in under ten years here. Stainless and copper caps hold up far longer in harbor air, and we’ll show you the difference before you choose.
Yes, but not until we know what’s actually inside the flue. On the older Brooklyn blocks where fireplaces were plastered over during oil-heat conversions and reopened decades later, flues are often packed with collapsed liner fragments, generations of bird nesting, and debris, and we won’t put a new cap on top of that mess. The camera inspection shows you what we’re dealing with, and we’ll give you a plain-English verdict before we recommend anything. For this kind of job, schedule Brooklyn Fireplace Services like a sweep and inspection first, then the cap; call (516) 289-9316.
A cracked crown lets freeze-thaw water penetrate the mortar bed each winter, and every cycle widens the cracks and spalls brick faces until the top courses of the stack loosen and leak. On Park Slope brownstones with original crowns and no prior crown repair work, this is one of the most common failure points we see, and it’s usually fixable with crown repair or coating if caught before structural damage spreads. Don’t assume that first hairline crack is cosmetic; call us and we’ll tell you what you’re actually looking at.
We size the cap’s mesh and profile to the vent’s actual BTU output and draft requirements, not to the old coal-era flue opening. A converted gas boiler flue in a Crown Heights brownstone often drafts through a flue that was originally sized for coal, and the wrong cap can trap debris, restrict draft, and push exhaust back into the row house. We measure, we calculate, and we show you the numbers before we fabricate or order anything, including any Brooklyn Duraflex service components. Call (516) 289-9316 for an exact quote, and remember: no trip charge inside the county, and a free second opinion on any competing written estimate.
