We’ve been dispatching crews to Borough Park from our New York City office for decades. We know the neighborhood’s attached brick row houses on 13th Avenue, 16th Avenue, and Ocean Parkway. We know the roof access is tight, the parking is tighter, and the chimneys are almost always shared between two or more units. That local knowledge changes how we approach every job.

Our Chimney Liner & Rebuild team doesn’t treat your house like a suburban standalone. We treat it like what it is: a 1910-1945 attached brick row house with a party-wall stack that may contain three, four, or five flues serving multiple households, any one of which could be compromised by the settling of the building next door.

Why Hearthstone Chimney Co. Is Borough Park’s Preferred Chimney Liner & Rebuild Company

Hearthstone Chimney Co. has served local communities for over 42 years. We’ve built our reputation one row house at a time, and in Borough Park that means understanding something no chain sweep from outside Brooklyn grasps: your chimney is not just yours. The stack embedded in your party wall likely serves your boiler, your upstairs tenant’s water heater, and possibly your neighbor’s appliance too. Russell Haines built this company on the principle that you can’t fix what you can’t see, and you can’t explain what you can’t show.

Our Level 2 camera inspections end with photos you can see and a plain-English verdict. No jargon. No scare tactics. If your flue is cracked, we show you the crack. If your neighbor’s flue is cracked too, we show you that and explain why it matters to your new liner’s draft. Documentation like an engineer, explanation like a craftsman.

Our Chimney Liner & Rebuild Services in Borough Park

Stainless Steel Liner Installation

A stainless steel liner is the right choice for most Borough Park boilers and water heaters being vented into original flues sized for coal. We use DuraFlex and Olympia Chimney products, not builder-grade substitutes. These liners handle the acidic condensation produced by modern gas appliances far better than the old clay flue tiles they replace. In a typical three-story attached row house off New Utrecht Avenue, a single-flue stainless install runs $2,800-$4,200. Multi-flue party-wall stacks cost more because each flue must be independently lined and properly capped at the crown.

Flexible Liner Systems

Some Borough Park chimneys have offsets or bends that rigid stainless can’t navigate, especially in buildings where prior repairs or settling have shifted the flue path. Flexible liners from DuraFlex solve this without dismantling the stack. We see this most often in the deeper row houses between 18th and 20th Avenues, where century-old construction tolerances were generous. Flexible systems cost roughly the same as rigid when the installation is straightforward, but add $400-$800 if we need to navigate significant offsets or repair the smoke chamber access.

Liner Replacement

Liner replacement is our most common Borough Park job, and it’s rarely just “pull the old, drop the new.” The original clay flue tiles in these 1910-1945 houses were sized for coal furnaces burning at 1,200°F. Your modern gas boiler runs cooler and wetter. An oversized flue produces weak draft, acidic condensation, and premature failure of whatever liner you install. We measure the appliance output, calculate the correct liner diameter, and sometimes recommend a partial rebuild of the smoke chamber or firebox to match. Typical liner replacement in Borough Park: $3,200-$5,800 for a single flue, $5,500-$7,500 for a multi-flue party-wall stack with camera inspection and coordination disclosure included.

Partial Rebuild

When the chimney crown, cap, or upper courses of brick have failed, a liner alone is pouring money into a leaking bucket. Brooklyn’s marine climate delivers sharp freeze-thaw cycling from December through March, and salt-laden air off Gravesend Bay accelerates spalling on exposed brick. We rebuild crowns with proper slope and drip edges, replace deteriorated caps, and repoint upper mortar joints with lime-compatible mixes that match the original construction. Partial rebuilds in Borough Park typically run $1,800-$4,500 depending on accessibility and how many linear feet of brick need repointing. We use HeatShield for smoke chamber parging where appropriate.

Trusted Brands We Service in Borough Park

We stock DuraFlex, HeatShield, and Copperfield products for Borough Park jobs, with common liner diameters and crown repair materials on our trucks. That means no waiting for parts when we find your flue tiles cracked during a fall inspection. We’ve learned which sizes move fastest in this neighborhood: 5.5-inch and 6-inch round for gas boiler retrofits, 7-inch for older oil-to-gas conversions still running at higher BTU. The right material, the right diameter, the right day. That’s how most jobs finish in a single visit.

Common Chimney Liner & Rebuild Problems We See in Borough Park Homes

• Cross-contamination between shared flues. We were called to a three-story attached brick row house off 13th Avenue where the second-floor tenant smelled exhaust in the kitchen every time the first-floor boiler fired. A camera scan showed the party-wall stack’s clay flue tiles cracked and offset from decades of differential settling between the two adjoining buildings, and the neighbor’s gas water heater was venting into the same compromised flue. We pulled a Level 2 inspection report for the landlord, dropped a DuraFlex stainless liner sized to the boiler, and HeatShield-sealed the smoke chamber so the two appliances stopped cross-talking.
• Gas conversion in an oversized coal flue. Flues originally sized for coal furnaces and then adapted for oil boilers are oversized for modern gas appliances. The result is chronic condensation, weak draft, and premature liner deterioration that cleaning alone cannot fix. We see this constantly in the two-family conversions along 46th Street and 50th Street.
• Frozen-thawed crowns letting water track down. The exposed chimney crowns on these attached brick stacks take the worst of Brooklyn’s winter. Lime mortar pits, brick spalls, and water finds its way behind your new liner. Annual inspection catches this before it becomes a rebuild.
• Relining one flue while ignoring the adjacent party-wall flue. A new liner in a compromised shared stack is only as good as the flue next to it. If your neighbor’s appliance still vents through cracked tiles, your draft suffers and your warranty may too. We camera-scan adjacent flues and document what we find.
