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 Cap & Crown Across Park Slope
A chimney cap or crown problem in Park Slope is rarely just a cosmetic issue. Salt air off Upper New York Bay attacks galvanized caps and mortar crowns faster here than in inland Brooklyn, and a failed crown on a 130-year-old brownstone stack lets water straight into the flue bed before you ever see a stain on the ceiling. We’ve been working Park Slope roofs and landmarks since 1999, and Wendell Pike still answers the phone himself. If you need a cap replaced, a crown rebuilt, or just a straight answer about what’s failing up there, call (516) 289-9316 and we’ll schedule a look.
What you get on the first visit is simple: a sweep who knows Victorian brick, a camera scan of your flues, and a plain-English verdict on whether the work is urgent or can wait. No scare-selling. No pressure. The number you hear on the phone is the number on the invoice.
Why Top Hat Chimney Is Park Slope’s Preferred Chimney Cap & Crown Company
We’ve been inside more Park Slope brownstone stacks than we can count. Wendell and his crew know the difference between an 1890s Italianate crown on Carroll Street and a 1910 Romanesque Revival stack off Prospect Park West. That matters when you’re deciding whether to patch, rebuild, or replace. Ask anyone on your street. We’ve worked this neighborhood since 1999, and the same face comes back when you call.
Every job is backed by our 90-Day Done Right Promise, in writing. If something isn’t right after we leave, one call brings us back at no additional cost. That’s not a marketing line; it’s stamped on every invoice we hand a Park Slope homeowner. And when you call, a live person answers, 24/7. It may well be Wendell himself picking up on a Sunday morning because a nor’easter tore a cap loose overnight.
We’re locally owned and owner-operated, with a published address and license number. No call center, no franchise that rotated in last spring. Wendell puts his name on the work and runs into you again Saturday morning at the Fifth Avenue farmers market.
Our Chimney Cap & Crown Services in Park Slope
Four jobs cover almost everything we do on Park Slope chimney tops. Here’s what each one involves and why the neighborhood’s housing stock makes it different from a generic cap job.
Cap Installation
A new cap on a Park Slope flue has to do two things: keep out rain, birds, and salt mist, and preserve the landmark-era profile that LPC cares about. We install stainless steel and copper caps sized to your flue, including multi-flue caps for the 3-flue stacks common on brownstone rows. If the building is in a Landmarks Preservation Commission Historic District, we’ll tell you before work begins whether the visible cap needs LPC review.
Cap Replacement
Galvanized caps on brownstones near Fifth Avenue and the park routinely rust through at the screws within two winters. Salt accelerates galvanic corrosion where the cap meets the flue tile. We pull the old cap, check the flue crown for hidden spalling, and install a replacement that actually fits the existing tile dimensions. A cap that doesn’t seat right lets rain cascade sideways into the flue, so we measure before we order anything.
Crown Repair
The crown is the concrete or mortar slab that caps the brick stack and sheds water. On Park Slope’s 100-150-year-old clay tile crowns, freeze-thaw cycling opens hairline cracks every March. We repair crowns by cleaning out failed mortar, rebuilding the slope, and sealing with a flexible elastomeric coating that moves with the brick instead of cracking against it.
Crown Coating
A crown that’s structurally sound but weathered can often be saved with a proper coating rather than a full rebuild. We apply elastomeric crown coats that bridge existing hairline cracks and resist Brooklyn’s salt air. This buys years on a crown that would otherwise fail by spring. If the crown’s already spalling at every corner, we’ll tell you that straight instead of selling you a coating that won’t hold.
Custom Cap
For brownstones with original multi-flue stacks, a stock cap often doesn’t match the masonry profile or the flue spacing. We fabricate custom stainless steel caps sized to serve two, three, or more separate flues while preserving the building’s original roofline character. This matters on landmark buildings, where an off-the-shelf cap that changes the visual profile can trigger LPC review. We work with Olympia Chimney and Copperfield products for custom applications.
Trusted Brands We Service in Park Slope
We install and service caps, crowns, and liner components from Copperfield, DuraFlex, HeatShield, and Gelco. That’s not a name-drop for the website. It means the parts we put on your Park Slope roof are the same brands we stock for rapid turnaround, and if a part fails under warranty, we handle the replacement directly with the manufacturer. For Park Slope brownstones with original clay tile liners, we often recommend HeatShield resurfacing rather than a full liner tear-out when the existing tile is salvageable. That’s a judgment call based on what the camera actually shows, not a script.
Common Chimney Cap & Crown Problems We See in Park Slope Homes
- Salt-driven cap corrosion. Galvanized cap screws rust through in two winters near Upper New York Bay. The cap loosens, lifts in a nor’easter, and rain pours straight down the flue. We replace galvanized with stainless whenever the building’s LPC status allows it.
- Freeze-thaw crown spalling. The short freeze-thaw cycles that roll through Brooklyn all winter crack the edges of century-old clay tile crowns. Hairline cracks open every March. We see this on nearly every uncoated crown over 80 years old.
- Uncapped and bricked-up historic flues. Renovations reopening a fireplace sealed since the 1950s often reveal flues with no cap at all, plus decades of compacted coal soot and creosote. Nesting starlings and nor’easter rain take the same route down.
- Multi-flue caps that don’t seat. Brownstone stacks with 3-5 separate flues need a cap sized to the actual tile dimensions. A generic cap that overhangs or under-seats lets wind-driven rain enter the abandoned flues and flood the smoke chamber below.

FAQs - Chimney Cap & Crown in Park Slope
Yes, if the cap is visible from the street and your building is inside a designated LPC Historic District, you may need LPC approval before any above-roofline cap replacement or crown rebuild. Many Park Slope blocks are LPC-designated, and a cap that changes the chimney’s visual profile can trigger review. We’ve helped owners through the LPC process before and will tell you at the estimate stage whether your building falls under it. Call (516) 289-9316 and we’ll check the designation.
Every year, and ideally before burning season. Salt air from Upper New York Bay accelerates corrosion on any metal component, including stainless, and an annual inspection catches loose screws, lifted seams, and debris before a nor’easter rips the cap off entirely. On brownstone stacks with 3 or more flues, we also check that the cap still seats tightly over each tile. Schedule a look before Thanksgiving.
Salt and freeze-thaw. The harbor’s salt-laden air accelerates mortar spalling, while Brooklyn’s coastal winter cycles of freezing nights and above-freezing days push water into hairline cracks and wedge them wider every March. An inland crown might hold for decades with routine maintenance, but a Park Slope crown needs coating or repair on a shorter interval. If yours has visible corner spalling, don’t wait for a ceiling stain to confirm it. Call (516) 289-9316 for a camera-backed assessment.
Yes, and that’s one of the most common jobs we do in Park Slope. A custom multi-flue cap is sized to the actual spacing and dimensions of your original clay tile liners, so each flue gets proper coverage without blocking draft or changing the building’s profile. We measure on-site and fabricate the cap to fit. This approach also preserves the landmark-era appearance that off-the-shelf caps often ruin.
The screws and the cap’s exposed seams go first, usually within two winters near the bay. Once the galvanized coating fails, the bare steel rusts through and the cap loosens. We replace galvanized caps with stainless steel whenever possible, sized to the existing flue tile. Stainless resists salt corrosion far longer and won’t fail at the screws. If you’re seeing rust streaks down your chimney brick, that’s the cap telling you it’s done.
