Why Hearthstone Chimney Co. of New York City Is Flatbush’s Preferred Fireplace Services Company
Flatbush homeowners have been calling us since 1984 because we document what we find and we say it plainly. Our Level-2 camera inspections end with photos you can see and a plain-English verdict, not a technical report that requires a translator. We’ve earned a strong local reputation in Brooklyn by showing up when we say we will and standing behind our work with the 90-Day Done Right Promise, in writing, no arguing.
Our response time to Flatbush is same-day or next-day for standard calls, and we stock professional-grade parts from Gelco and Olympia Chimney so most jobs finish in a single visit. We understand the specific hazards of Flatbush’s housing stock: shared chimney breasts between semi-detached homes, unpermitted flue conversions from the 1970s and 1980s, and sulfur-deposit buildup from oil combustion that newer markets never see. Background-checked, uniformed technicians arrive with upfront pricing, the number on the estimate is the number on the invoice.
Our Fireplace Services in Flatbush
Gas Fireplace Service
Most Flatbush homes never had functional wood-burning fireplaces to begin with. The decorative coal fireplaces in these 1910s-1940s rowhouses were abandoned long ago, and today’s homeowners want clean, efficient gas. Our gas fireplace service includes burner inspection, gas-line pressure testing, valve and thermocouple replacement, and venting verification. We work with professional-grade materials from Famco and Copperfield. In Flatbush, the critical step is confirming your flue is properly dedicated and lined, not shared with a neighbor’s water heater or an abandoned coal vent. On E 18th Street, we serviced a semi-detached two-family where the homeowner’s gas water heater was illegally venting into a neighbor’s capped coal flue. Our crew installed a HeatShield liner system and rerouted the flue to a dedicated clay liner, correcting a carbon monoxide risk that had gone undetected for years.
Wood Burning Fireplace
True wood-burning fireplaces are rare in Flatbush’s housing stock, but some homeowners on blocks like Albemarle Road and Glenwood Road have intact original fireboxes they want to restore for occasional use. We inspect the firebox for cracked refractory panels, check the damper operation, and verify the flue is clear of the blockages that accumulate when these units sit unused for decades. If the chimney breast is shared with an adjacent unit, we map every flue before any work begins. Safety comes first: an improperly vented wood fire in a pre-war rowhouse can expose multiple families to smoke and carbon monoxide.
Fireplace Insert
A fireplace insert lets you convert an old, inefficient masonry opening into a sealed combustion system without rebuilding the entire chimney structure. In Flatbush, where many original fireplaces are shallow and the flues were sized for coal, proper insert selection and installation requires precise measurement and often a new stainless steel liner from DuraFlex. We handle the full installation, including any necessary firebox repair, and we confirm the insert vents independently of other appliances in the shared chimney. Most Flatbush insert jobs we complete in one day.
Damper Repair
A stuck or rusted damper wastes heat and can let downdrafts blow soot into your living room. In Flatbush’s coastal climate, moisture intrusion through cracked chimney crowns corrodes damper hardware faster than inland markets. We replace failed throat dampers with new cast-iron or stainless steel units, and we install top-sealing dampers from Gelco when the original throat damper is too deteriorated to salvage. A proper damper seal also keeps out the rain and salt air that accelerate mortar erosion in these old brick stacks.
Fireplace Conversion
Converting a coal or oil-era fireplace to gas is our most common Flatbush request. These conversions demand more than running a gas line. We inspect the flue size against the appliance BTU rating, install a proper liner if the existing clay flue is unlined or undersized, and we verify venting does not intersect with any neighboring unit’s system. Our crew documents the new configuration with photos and a written report, so the next owner, inspector, or technician knows exactly what they’re looking at. No more undocumented conversions.
Firebox Repair
Cracked firebrick and deteriorated mortar in the firebox create a direct path for heat and combustion gases to reach the wooden framing of your Flatbush rowhouse. We repoint firebox joints with refractory mortar and replace damaged brick or paneling. In homes where the firebox has been altered by previous owners, we rebuild to safe dimensions using materials rated for the intended fuel type.
Trusted Brands We Service in Flatbush
We stock parts and materials from professional-grade brands that hold up in Flatbush’s demanding conditions: HeatShield for ceramic flue liner restoration, Gelco for chimney caps and dampers that resist coastal corrosion, and Olympia Chimney for stainless steel liner systems sized to pre-war flue dimensions. We don’t use builder-grade substitutes. Our Flatbush customers get the same materials we’d install in our own homes, and because we keep inventory on our trucks, most repairs don’t wait for a parts order.
Common Fireplace Services Problems We See in Flatbush Homes
- Undocumented flue configurations from decades of unpermitted conversions. Landlords in Flatbush tied gas water heaters into abandoned coal flues without permits, without liners, and without maps. Our camera inspections find these hidden connections before they become carbon monoxide hazards.
- Crown and mortar joint failures accelerated by freeze-thaw cycling. Brooklyn’s coastal moisture penetrates soft pre-WWII common brick, then winter temperatures drop below freezing and the expanding ice spalls the surface. Water enters the flue system and compounds sulfur deposit buildup from oil combustion.
- Shared chimney breasts with dangerous inter-unit gas migration. On Flatbush’s tightly packed rowhouse blocks, a single chimney breast between two semi-detached homes can contain four or more flues. We’ve found gas water heaters venting into neighbors’ capped flues, and “unused” fireplace flues pressed into service for modern appliances with no liner.
- Undersized or unlined flues left over from fuel conversions. When Flatbush buildings converted from coal to oil to gas, the flues were rarely re-engineered. A flue sized for coal combustion is often too large for modern gas appliances, causing condensation and corrosive deposit buildup that destroys liners from the inside.

FAQs - Fireplace Services in Flatbush
Flatbush rowhouses were built with one flue for the coal furnace, one for the coal fireplace, and sometimes one for a kitchen stove, then landlords converted fuels and appliances over decades without filing permits or updating flue maps. By the 1980s, a single chimney might contain a gas water heater, an oil boiler, and an abandoned fireplace flue, with no written record of which was which. Our Level-2 camera inspection identifies each flue’s current use and condition, and we provide photos and a plain-English report you can keep for future contractors. Call (855) 950-3861 to schedule.
Salt-laden air and frequent rain penetrate the soft common brick typical of pre-WWII Flatbush construction, then winter freeze-thaw cycles expand the water into ice that cracks and spalls the mortar surface. This erosion accelerates in chimneys with failed crowns, allowing water directly into the flue system where it compounds corrosive sulfur deposits from oil combustion. We inspect crown and mortar condition on every visit, and we repair with materials rated for coastal exposure. Annual inspection catches this before major rebuilds are necessary.
Yes, if the flue is properly lined, sized for the appliance BTU rating, and dedicated solely to that fireplace. Most original coal flues in Flatbush are unlined and were later used for other appliances, so we first run a camera to verify the flue’s interior condition and confirm no other unit is sharing the vent path. We then install a stainless steel liner and proper termination cap, and we test the complete system before lighting the pilot. The work is documented with photos and our written verdict for your records and any future home sale.
Unexplained moisture or rust in a flue you believe is unused, soot or oily residue in a supposedly abandoned fireplace, or the smell of combustion gases when your own appliances are off. In Flatbush’s semi-detached two-families, we’ve found cases where a landlord’s gas water heater was tied into a neighbor’s capped coal flue years ago, creating a carbon monoxide pathway between units. If you suspect cross-venting, stop using the affected fireplace and call us for an emergency inspection. This is not a DIY diagnosis.
Extremely common. When Flatbush buildings converted from coal to oil in the mid-20th century, and later from oil to gas, the flues were rarely relined or resized to match the new appliance. Oil combustion produces sulfur deposits that corrode unlined clay, and gas appliances in oversized flues create acidic condensation that destroys mortar from the inside. Our inspections regularly find these conditions in 11226, and we correct them with properly sized stainless steel liners from Olympia Chimney or HeatShield ceramic systems. The fix is straightforward once it’s identified.
