Our Fireplace Services in Park Slope
Gas Fireplace Service
Park Slope’s gas fireplace inserts—often installed during 1990s and 2000s renovations—sit in flues never designed for them. The original coal-era terra cotta liner may be cracked, partially removed, or simply too large for efficient gas venting. We inspect the burner assembly, check gas pressure at the manifold, and verify that your venting configuration matches the insert’s listed requirements. A typical gas fireplace service in Park Slope runs $180–$320. If the flue needs relining for safe gas operation, we spec DuraFlex or HeatShield systems sized to your specific insert model.
Wood Burning Fireplace Repair
Yes, some Park Slope homeowners still burn wood—especially in the larger 3- and 4-family brownstones with original fireplaces intact. The problem is those 1880s fireboxes were built for coal grates, not modern wood-burning practices. We repair deteriorated firebrick, re-point failing mortar joints with high-temperature refractory material, and evaluate whether your flue can handle wood smoke safely. Firebox repair in Park Slope typically costs $450–$1,200, depending on how much original masonry needs rebuilding. We won’t sign off on wood burning in a flue that’s structurally compromised—period.
Fireplace Insert Installation & Service
Inserts are the practical choice for Park Slope’s drafty, oversized fireplaces. We size and install units that fit your existing opening without destructive modification to historic mantels or hearths. Critical detail: the insert is only half the job. The liner connection—usually a flexible DuraFlex run from insert collar to chimney top—is where corners get cut. We pull permits when required, install proper termination caps, and document the work for your insurance or future sale. Insert installation with liner in Park Slope ranges from $2,800–$4,500.
Damper Repair & Replacement
A stuck or missing damper in a Park Slope brownstone isn’t just an efficiency problem—it’s a heat-loss nightmare in 3,000-square-foot units with original windows. We repair cast-iron throat dampers, install top-sealing dampers for better closure, and address the rusted pivot arms and corroded frames we find in these century-old assemblies. Damper repair runs $220–$380; full replacement with a new top-sealing unit is $450–$650.
Chimney Liner Repair & Retrofit
This is where Park Slope’s housing stock demands real expertise. On Third Street, we serviced a two-family brownstone where the original coal-era terra cotta liner had cracked under 130 years of freeze-thaw cycles. Rather than a full rebuild, we installed a HeatShield cast-in-place liner to seal the flue and retrofit it for a new gas insert, preserving the historic chimney stack while meeting modern safety codes. Liner repair or retrofit in Park Slope ranges from $1,800–$3,800 depending on flue count, height, and access.
Fireplace Conversion (Wood to Gas)
Converting a wood-burning or coal-era fireplace to gas in a Park Slope brownstone involves more than dropping in a log set. We evaluate the flue size against your chosen gas appliance’s BTU output, verify adequate combustion air in the firebox, and run a new gas line if your existing service can support it. The old flue almost always needs a dedicated liner. Full conversion with liner and permit-ready documentation runs $3,200–$5,500 in Park Slope’s market.
Trusted Brands We Service in Park Slope
We stock and install professional-grade materials from Famco, Copperfield, DuraFlex, and HeatShield—brands specified by chimney professionals, not sold at big-box retailers. For Park Slope customers, that means faster turnaround on repairs that would otherwise wait for specialty orders. A cracked crown that needs Copperfield crown seal, a deteriorating flue that takes a DuraFlex stainless liner, a firebox that needs HeatShield refractory resurfacing—we carry the materials and know how each performs in Brooklyn’s freeze-thaw environment. When your neighbor’s contractor is still waiting on a delivery, we’re already finishing the job.
Common Fireplace Services Problems We See in Park Slope Homes
- Disintegrated lime mortar between terra cotta flue tiles. The original mortar joints in these 1880s–1910s chimneys turn to powder after a century of acid exposure and thermal cycling. Flue gases leak into wall cavities, adjacent apartments, or even the neighbor’s chimney through shared party-wall construction.
- Cracked corbeled brick crowns from Brooklyn’s freeze-thaw assault. Temperatures cross 32°F repeatedly each winter, driving water into micro-cracks that expand, contract, and spall masonry from the inside out. By March, we’re repairing crowns that were intact in October.
- Improperly abandoned flues creating cross-unit CO pathways. A flue once used for coal, then oil, now capped off with a piece of sheet metal and caulk—still open at the bottom, still connected to the same chimney chase your neighbor shares. Carbon monoxide doesn’t respect property lines.
- Gas inserts venting into oversized, unlined coal flues. The previous owner “saved money” skipping the liner. Now you’re venting acidic gas exhaust into a 130-year-old terra cotta system with missing tiles and open mortar joints. It’s more common than you’d think on streets like President and Carroll.

FAQs — Fireplace Services in Park Slope
The National Fire Protection Association recommends annual inspection for all chimneys, and in Park Slope’s 100+ year old housing stock, we consider that a minimum. Brooklyn’s freeze-thaw cycle accelerates crown and mortar deterioration, and shared party-wall flues create hazards no annual check should miss. Call (833) 349-5892 to book—estimates are free, and we’ll put you on a yearly reminder cycle.
Yes, absolutely. We find unlined or improperly lined flues behind roughly half the gas inserts we inspect in Park Slope, especially in buildings converted during the 1980s and 90s boom. The oversized coal-era flue doesn’t vent gas exhaust efficiently, and deteriorated terra cotta can block the chimney or leak CO into adjacent units. We run a camera inspection to confirm liner condition—$180–$320 for the service call, and you’ll know exactly what you’re dealing with.
A proper conversion requires three things: a gas-certified insert or log set sized to your firebox, a dedicated flue liner matched to the appliance’s venting requirements, and adequate combustion air supply. In Park Slope’s tight rowhouses, we often need to evaluate whether your existing chimney chase can accommodate a new liner without disturbing party-wall separation. The full job runs $3,200–$5,500 and takes 1–2 days with Paul Torres on-site throughout.
Most crown damage in Park Slope is repairable if caught before water has destroyed the brick courses beneath. We grind out loose material and apply a formulated crown seal—Copperfield or HeatShield depending on exposure and access—or pour a new concrete crown if the original corbeled brick is too far gone. Crown repair runs $450–$1,100; full rebuild only becomes necessary when spalling has compromised multiple brick courses below. Annual inspection catches this early.
Evacuate immediately and call 911 if you suspect carbon monoxide; then call us. This is the cross-unit hazard unique to Park Slope’s attached housing—smoke or CO migrating through a shared chimney chase because a flue was improperly abandoned or its liner breached. We’ve documented this on streets from 1st to 9th, and it’s not something suburban chimney companies encounter. We inspect both flue systems, identify the failure point, and coordinate repairs that protect both properties. Call (833) 349-5892—we’ll prioritize same-day response for active CO concerns.
