We’ve been working on Brooklyn Heights chimneys since 1984. We know the difference between a standard cap job on a 1970s condo conversion and a Landmarks Preservation Commission review on a Willow Street Greek Revival original. Our Chimney Cap & Crown team has navigated shared party-wall flues, coordinated with co-op boards on Pierrepont Street, and sourced custom copper that matches the historic roofline on Columbia Heights. Brooklyn Heights isn’t like the rest of Brooklyn. The work isn’t either.
Why Hearthstone Chimney Co. of New York City Is Brooklyn Heights’s Preferred Chimney Cap & Crown Company
Forty-two years in this trade means we’ve watched Brooklyn Heights shift from a quiet enclave of longtime owners to a mix of preserved originals and careful restorations. The owners who call us have usually lived in their houses for twenty-plus years. They’ve seen contractors come and go. They want the job done right because they plan to stay.
Our reputation here is built on documentation. Every inspection ends with photos you can see and a plain-English verdict. No jargon, no scare tactics. If your crown needs a coating, we show you the spalling mortar. If your cap is missing and rain is pooling on your smoke shelf, we explain why before we quote. The 90-Day Done Right Promise backs every job in writing. If it’s not right, we come back. No paperwork, no arguing.
Response time to Brooklyn Heights is same-day or next-day for standard calls, and we stock the professional-grade materials that let our background-checked, uniformed technicians finish most jobs in a single visit. No return trips for parts we should have had on the truck.
We also know the local rules. Any exterior chimney work visible from the street in Brooklyn Heights’s Historic District triggers LPC review. We’ve filed those applications before. We know the timeline, the photo requirements, and the difference between a repair that qualifies as maintenance and one that needs full approval. That local knowledge saves weeks of delay.
Our Chimney Cap & Crown Services in Brooklyn Heights
Cap Installation
New cap installation in Brooklyn Heights runs $280-$520 for a standard single-flue galvanized or stainless steel cap, and $680-$1,200 for a custom multi-flue cap in copper or stainless. The price difference reflects the neighborhood’s reality: many brownstones need multi-flue caps because their original chimney stacks were built to serve multiple fireplaces across two or three units. A cap sized for one flue won’t protect a stack that vents two or three. We measure every flue, check for shared wythes, and fabricate or source caps that fit the actual chimney, not a generic spec.

Cap Replacement
Replacing an existing cap in Brooklyn Heights often reveals more than the homeowner expects. The old cap may have been hiding a cracked crown, or the flue may have been sealed with an improvised mortar plug during a 1980s gas conversion. Our replacement process includes a Level-2 camera inspection so you know what you’re actually getting before the new cap goes on. Standard replacement with inspection: $340-$580. If we find the flue is shared with your neighbor and the cap needs to coordinate with their venting, we’ll explain the situation and quote accordingly. No surprises on the bill.

Crown Repair
Crown repair is the most common call we get in Brooklyn Heights, and for a specific reason. The neighborhood sits on a bluff 40-60 feet above the East River and New York Harbor. That elevation exposes chimney crowns to sustained southwest winds that funnel through the harbor, accelerating mortar joint deterioration. A crown that might last twenty years in sheltered Crown Heights shows cracks in twelve here. Crown coating with a flexible waterproof sealant runs $340-$520. Full crown rebuild with proper slope and overhang: $780-$1,400. We use professional-grade crown repair materials from Olympia Chimney and HeatShield, formulated to handle thermal cycling and wind-driven rain.

Crown Coating
For crowns with hairline cracks and minor spalling but intact structural integrity, crown coating is the right call. We apply a flexible, breathable sealant that bridges small cracks while allowing moisture vapor to escape. In Brooklyn Heights, where harbor winds drive rain horizontally into crown mortar, this coating adds critical protection without the cost of full rebuild. The process takes two to three hours, and the material cures to a finish that matches most existing concrete crowns. Cost: $340-$480, including surface prep and minor crack filling.

Multi-Flue Cap
Multi-flue caps are essential for many Brooklyn Heights brownstones. Original chimney stacks on Henry Street, Remsen Street, and Joralemon Street were built with multiple flues to serve parlor fireplaces, second-floor bedrooms, and kitchen ranges. When those units were later subdivided into apartments or condos, the flues often remained shared across legal boundaries. A multi-flue cap covers the entire stack with a single protective hood, individual screened outlets for each flue, and integrated dampers where needed. Custom fabrication in copper or stainless steel: $850-$1,600. We recently serviced a row of attached brownstones on Willow Street where a shared multi-flue stack had a cracked crown from years of harbor wind exposure. After coordinating with the Landmarks Preservation Commission, we installed a custom multi-flue copper cap with individual dampers, restoring proper draft for both units without compromising the historic roofline.

Custom Cap
Custom caps solve problems that off-the-shelf products can’t touch. A flue that’s been relined with an oval or rectangular stainless insert needs a cap built to that exact dimension. A historic district requires a copper finish that weathers to match neighboring roofs. A shared stack needs a cap with divided compartments to prevent cross-drafting between units. We fabricate custom caps in copper and stainless steel, working with Gelco and Copperfield materials, and we file LPC documentation when the cap will be visible from the street. Typical custom cap with measurement, fabrication, and installation: $920-$1,800.

Trusted Brands We Service in Brooklyn Heights
We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from Olympia Chimney, Gelco, and Copperfield, the brands that other sweeps call when they can’t source the right part. For Brooklyn Heights customers, this means faster turnaround and caps that fit correctly the first time. A standard Gelco stainless cap in a common size can be on your chimney the same day we measure. A custom Copperfield copper cap for an LPC-reviewed restoration ships to our fabricator with specs already confirmed. We’ve built relationships with these suppliers over four decades. That translates to parts availability that one-truck operators simply can’t match.
Common Chimney Cap & Crown Problems We See in Brooklyn Heights Homes
- Shared party-wall flues complicate access and ownership. A single cap replacement can affect two separate households, and one neighbor may not grant roof access or agree on scope. We document the flue configuration with camera inspection and help coordinate between parties before work begins.
- Wind-driven rain from the harbor penetrates deteriorated crown mortar. Brooklyn Heights’s exposed bluff position means horizontal rain hits chimney crowns harder than in sheltered interior neighborhoods. Water seeps through cracked mortar, rusts dampers, damages fireboxes, and stains ceilings before the homeowner realizes the cap was compromised.
- Decades-old gas-conversion seals block flues that need capping. Technicians routinely encounter fireplace flues sealed with improvised mortar plugs, sheet metal, or old gas inserts during the 1960s-1980s conversions. These must be carefully removed before a new cap can fit, often revealing unexpected shared liners or deteriorated clay tile.
- LPC review delays exterior work on visible chimneys. Any cap or crown repair visible from the public way in Brooklyn Heights’s Historic District requires Landmarks Preservation Commission approval. We file the paperwork, provide the photos, and know the difference between maintenance exemptions and full review.

LPC coordination adds administrative hours we don’t charge separately, but it does extend the timeline. Shared flues may require two-party agreements that complicate scheduling.

FAQs - Chimney Cap & Crown in Brooklyn Heights
Yes, if the chimney is visible from a public street within the Brooklyn Heights Historic District. Maintenance-level repairs that don’t alter appearance may qualify for an exemption, but anything involving custom fabrication, material change, or visible modification requires LPC review. We file the application, provide required documentation, and coordinate the timeline. Call (855) 950-3861 and we’ll check your specific address against district boundaries.
You won’t know without a camera inspection. The 1850s speculative builders in Brooklyn Heights often constructed party-wall chimneys with shared wythes of brick, and sometimes shared clay tile liners, to save material and labor. One household’s flue may run parallel to or even intersect with the neighbor’s inside the same stack. Our Level-2 camera inspection maps the flue interior and identifies shared construction. If we find it, we explain the implications for cap selection and coordinate with all affected parties before proceeding.
A multi-flue cap covers the entire chimney top with a single hood, protecting all flues and the crown between them. Individual caps mount on each flue separately, leaving the crown exposed to weather. For Brooklyn Heights brownstones with multiple flues in one stack, multi-flue caps are usually the better choice because they protect the crown, prevent wind-driven rain from entering between flues, and present a cleaner visual profile that LPC reviewers prefer. Custom multi-flue caps also allow individual dampers for each unit in a subdivided building.
Yes, and you should. Sealed fireplaces still have flues that vent moisture, carry stray combustion gases, or may have been improperly sealed. Before installing a cap, we inspect the flue with a camera to confirm it’s clear, remove any deteriorated mortar plugs or sheet metal blocking the opening, and verify whether the flue is shared. A properly capped, sealed flue prevents water intrusion and animal entry while allowing necessary ventilation. Installation with inspection and seal removal: $380-$620.
A well-fabricated copper cap lasts 50-70 years, even with harbor salt exposure. Copper forms a protective patina that actually slows corrosion. In Brooklyn Heights, the same southwest winds that damage mortar joints help copper develop its characteristic green-gray surface that blends with historic roofing. The critical factor is fabrication quality: seams must be properly soldered, base flashing must integrate with existing roofing, and the cap must be secured against wind uplift. We fabricate to those standards and guarantee the installation with our 90-Day Done Right Promise. For a quote on custom copper, call (855) 950-3861.
