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.

We’ve worked on Flatbush chimneys for decades. The big Victorians along Marlborough Road, the semi-detached brick rows off Cortelyou, the pre-war apartment buildings near Brooklyn College - each has its own chimney story, and most of them involve flues that have been through more fuel changes than the homes have had owners. That’s why we start every job with a Level-2 camera inspection, show you the photos, and give you a plain-English verdict before any work begins. No surprises on the bill. The number on the estimate is the number on the invoice.

Why Hearthstone Chimney Co. Is Flatbush’s Preferred Fireplace Services Company
Flatbush homeowners tend to stay put. They’ve owned their houses for twenty, thirty, forty years, and they’ve learned to spot a contractor who talks fast and leaves faster. We don’t. We’ve been answering the phone with a live person for over 42 years, and our 90-Day Done Right Promise is in writing with no arguing - if it’s not right, we come back. That’s the Keystone Standard: Krafted right, Every time, Your home first, Standing behind it.
Our technicians are background-checked and uniformed, and they complete most jobs in a single visit. We use professional-grade materials from DuraFlex, HeatShield, and Olympia Chimney - no builder-grade substitutes. When we say we’ll be there when we say, we mean it. And when we inspect your chimney, you get photos you can see and a verdict you can understand. No jargon, no scare tactics, just the condition of your flue in plain English.
Dispatch and scheduling are coordinated from our New York City office, but our crews serve Flatbush locally. We know the tight roof access between attached properties, the shared stacks in the older multifamily buildings, and the freeze-thaw punishment that Brooklyn’s interior position dishes out to exposed Victorian chimney crowns. That local knowledge saves time and prevents callbacks.
Our Fireplace Services in Flatbush
Wood Burning Fireplace Service
Wood burning fireplace service in Flatbush runs $220-$450 for a standard sweep and inspection, and $650-$1,800 if we find cracked terracotta liners or a corroded smoke chamber that needs HeatShield restoration. The wood-frame Victorians of Ditmas Park were built with parlor fireplaces meant for coal, converted to oil, then often abandoned or capped. When a new owner wants to burn wood again, we routinely find century-old clay tile flues coated with mixed-fuel creosote and cracked from decades of incompatible use. We clean it, camera it, and tell you honestly whether it’s safe to light. Sometimes it is. Sometimes it needs a liner first. You’ll know before we touch a tool.

Gas Fireplace Service
Gas fireplace service in Flatbush costs $180-$320 for a seasonal tune-up and safety check. Many Flatbush homes have gas inserts or log sets fitted into original masonry fireplaces, and the conversion was often done without proper relining. We check the gas pressure, inspect the burner assembly, test the pilot and thermocouple, and run a camera to confirm the flue is venting correctly. In attached and semi-detached housing, a neighbor’s gas appliance venting into a shared or adjacent stack can push exhaust into your fireplace flue. We find that. We fix that.

Fireplace Insert Installation
Fireplace insert installation in Flatbush ranges $2,400-$4,200 depending on the unit size, liner requirements, and whether the existing firebox needs repair. For Flatbush’s 1895-1925 housing stock, we typically specify inserts from Olympia Chimney paired with a properly sized stainless liner - the original flue was designed for coal draft, not modern efficiency, and an insert without correct venting is a carbon monoxide risk. We measure twice, install once, and stand behind it with our 90-Day Done Right Promise.

Damper Repair and Replacement
Damper repair in Flatbush runs $280-$550 for a top-sealing damper replacement, or $180-$320 for throat damper adjustment and sealing. The original cast-iron throat dampers in Flatbush Victorians rust solid after a century of mixed-fuel moisture. On Buckingham Road we opened a parlor firebox on a 1900s Victorian and found the fireplace flue sharing its stack with the home’s gas boiler flue, with a century of mixed-fuel creosote coating the original clay tile liner. We ran a camera down the flue, found cracked tiles and a rusted damper, then relined the fireplace flue with a HeatShield-cured liner and fitted a new top-sealing damper so the boiler flue and fireplace flue vent independently again. That’s the kind of problem a visual inspection misses and a camera catches.

Firebox Repair
Firebox repair in Flatbush costs $450-$1,200 for refractory panel replacement or HeatShield resurfacing, and $1,800-$3,500 for full firebox rebuild in severe cases. The original brick fireboxes in Flatbush’s wood-frame Victorians were built with common brick, not refractory, and decades of overheating or moisture intrusion from a failed crown have them spalling and cracking. We document the damage with photos, explain what can wait and what cannot, and give you an upfront price before any work starts.

Fireplace Conversion
Fireplace conversion in Flatbush - wood-to-gas, gas-to-wood, or coal-to-modern - runs $1,800-$4,500 depending on the existing condition and code requirements. Every conversion in NYC requires compliance with fuel-gas code and proper venting verification. We handle the inspection documentation and install only professional-grade components from brands we trust.

Trusted Brands We Service in Flatbush
We stock parts and materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney - professional-grade brands, no substitutes. For Flatbush’s older homes, that means we can often source the right liner diameter, the correct damper fit, or the proper crown repair material without a two-week order delay. Fast turnaround matters when your heat is down or your fireplace is unsafe to use. We don’t send a technician to guess at sizes and come back later. We measure, we stock, we install, and we stand behind it.
Common Fireplace Services Problems We See in Flatbush Homes
- Shared-stack cross-contamination. In the large free-standing Victorians of the Ditmas Park Historic District, a single brick chimney stack commonly carries a heating-appliance flue and a parlor fireplace flue side by side, so a neighbor’s appliance venting into a shared or adjacent stack can push combustion gases and creosote odors into a fireplace that hasn’t been burned in years. The homeowner smells “something from the furnace” and doesn’t know why. We do.
- Cracked terracotta liners from fuel-switching history. Original terracotta liners in 1895-1925 Victorians are undersized and cracked from fuel switches - coal to oil to gas, often without proper relining - causing smoke chamber and damper corrosion that only a Level 2 camera inspection catches. A visual check from the top or bottom misses this entirely.
- Freeze-thaw crown and mortar damage. Brooklyn’s freeze-thaw cycle, with temperatures repeatedly crossing 32°F through winter, accelerates mortar joint deterioration and spalling in Flatbush’s aged brick chimney stacks. The neighborhood’s position in interior Brooklyn means hard winters hit the exposed Victorian rooflines without the slight thermal moderation felt closer to the shore, making annual crown and mortar inspections especially critical.
- Tight roof access hiding flashing damage. Roof access between attached and semi-detached Flatbush properties is often too tight for standard ladder placement, so crown and flashing damage goes unseen until water stains appear on the ceiling below. We bring the right equipment for tight access, and we photograph everything we find.

FAQs - Fireplace Services in Flatbush
A neighbor’s boiler or water heater is likely venting into a shared or adjacent stack, and the exhaust is being drawn down your unused fireplace flue. In Flatbush’s attached and semi-detached housing, and especially in the large Victorians with multiple flues in one brick stack, this cross-contamination is common. We identify the source with a smoke test and camera inspection, then seal or reline the affected flue so your fireplace air stays separate from your neighbor’s exhaust. Call (516) 613-3035 for an exact quote - estimates are free.

You don’t, not without a Level-2 camera inspection. Cracks in century-old terracotta are rarely visible from the firebox or the chimney top. In Flatbush’s 1895-1925 housing stock, original liners were sized for coal draft and have been stressed by decades of oil and gas conversion. We run a camera, show you the footage, and explain whether the damage requires immediate relining or can be monitored. No guesswork. Call (516) 613-3035 to schedule.

They can share the same brick structure, but each fuel type needs its own properly sized, independent flue. In Flatbush’s Victorian chimneys, we routinely find a gas boiler flue and a fireplace flue in the same stack with damaged separation or a missing liner. That’s a carbon monoxide risk and a code violation. We reline with separate, correctly sized flues - often using HeatShield or DuraFlex materials - so each vents safely. Call (516) 613-3035 for an inspection.

Flatbush sits in interior Brooklyn without the slight thermal buffer of shoreline neighborhoods, so hard freeze-thaw cycles hit exposed Victorian chimney crowns directly. Temperatures cross 32°F repeatedly through winter, water seeps into micro-cracks, freezes, expands, and spalls the brick and mortar. Annual inspection catches this before water enters your home. Call (516) 613-3035 to book - estimates are free.

We install professional-grade inserts and liners from Olympia Chimney, DuraFlex, and HeatShield - brands engineered for the tight clearances and draft requirements of Flatbush’s original masonry. We do not use builder-grade substitutes. Every installation is documented with photos and covered by our 90-Day Done Right Promise. Call (516) 613-3035 to discuss sizing and options for your specific fireplace.
