Why Hearthstone Chimney Co. of New York City Is Tremont’s Preferred Fireplace Services Company
Tremont building owners call us because we understand what we’re walking into. A standard sweep in a suburban colonial is one thing. A multi-flue chimney stack in a 1920s tenement, with decades of coal and oil residue compacted in the flue, is another job entirely. We’ve cleaned and relined hundreds of these stacks across the Bronx, and we document every inspection with photos you can see and a plain-English verdict.
Our response time to Tremont averages same-day or next-day during the heating season. We don’t make you wait a week while your boiler sits tagged out. Our technicians are background-checked, uniformed, and trained to work in tight spaces - basement crawlspaces, alley-load entries, shared mechanical rooms. Most jobs finish in a single visit.
Frank Calucci has led Hearthstone Chimney Co. since its founding in 1984. The company was built on the K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it. That means the 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back. We’ve been answering the phone with a live person for over 42 years, and we plan to be here in thirty more.
Our Fireplace Services in Tremont
Gas Fireplace Service
Gas fireplace service in Tremont runs $180-$320 for a standard tune-up and safety inspection. Many Tremont buildings are mid-conversion from #4 or #6 fuel oil to natural gas under NYC’s Local Law 97 clean-heat mandates. The old oil flues are often oversized for a gas appliance’s lower BTU output. That mismatch causes condensation, rapid creosote re-accumulation, and failed inspections. We check burner orifice alignment, gas pressure, venting configuration, and carbon monoxide spillage - and we’ll tell you straight if your flue needs relining before the NYC DOB will sign off.
Fireplace Conversion
Converting a coal or oil fireplace to gas in Tremont typically costs $1,800-$3,500, including the DuraFlex stainless steel relining kit required for code compliance. This is where Tremont’s housing stock gets complicated. Your chimney stack may have served coal in the 1920s, heavy fuel oil through the 1980s, and now needs to handle natural gas. Each fuel transition deposited a chemically distinct residue layer, and the flue diameter requirements changed each time. We size the new liner precisely for your appliance’s BTU output, install it to NFPA 211 standards, and provide the documentation your building needs for NYC DOB certificate of operation.
Damper Repair
Damper repair in Tremont costs $220-$380 for a standard throat damper replacement, or $450-$750 for a top-sealing energy-efficient damper with professional installation. In Tremont’s dense attached housing, a stuck or rusted damper isn’t just a draft problem - it’s a heat-loss problem that drives up bills for every unit sharing the stack. We inspect the damper plate, frame, and operating mechanism, then replace with components sized for your flue. If the firebox throat is deteriorated from decades of corrosive oil combustion, we’ll document it and show you the photos.
Wood Burning Fireplace
Wood burning fireplace cleaning and inspection in Tremont runs $220-$340. Most Tremont wood-burning units are in older rowhouses or have been retrofitted into pre-war fireplaces originally built for coal. The flue may be unlined, or lined with terra cotta tiles that have cracked from freeze-thaw cycling in The Bronx’s damp winters. We power-sweep the flue, inspect with a level-2 camera, and check for spalling brick, breached mortar joints, or carbon monoxide migration paths between units. If we find crumbled flue tiles, we’ll show you the footage and explain your options.
Fireplace Insert
Fireplace insert installation in Tremont ranges $2,200-$4,000 depending on unit size, liner requirements, and whether we need to modify the existing firebox. Inserts must be connected to a properly sized stainless steel liner running the full flue height - a critical step in multi-unit buildings where an improperly vented insert can pressurize adjacent flues. We work with inserts from major manufacturers and handle the full installation, including any necessary relining, to NFPA 211 and NYC code.
Firebox Repair
Firebox repair in Tremont typically runs $450-$1,200 for refractory panel replacement or tuckpointing, or $1,800-$3,500 for a full HeatShield cerfractory resurfacing. Tremont fireboxes have endured decades of coal, oil, and now gas combustion - each fuel stressing the refractory differently. We assess the firebox walls, floor, and throat, then recommend repair or resurfacing based on what we find. HeatShield provides a UL-listed, 2400°F-rated surface that restores structural integrity without a full rebuild.
Trusted Brands We Service in Tremont
We stock parts and materials from DuraFlex, HeatShield, and Copperfield - professional-grade brands, no builder-grade substitutes. For Tremont’s gas conversions and relining work, we keep DuraFlex stainless steel liner kits in common diameters on our trucks, which means faster turnaround when your building is facing a DOB deadline. We don’t order parts from a catalog and make you wait two weeks. When we say we’ll be there when we say, we mean it.
Common Fireplace Services Problems We See in Tremont Homes
- Multi-fuel residue buildup. In Tremont’s pre-war attached brick buildings, a single exterior chimney stack often contains four or more flues serving different units. Decades of coal then oil combustion have left compacted, mixed-composition soot that is harder to clear than typical residential fireplace creosote. A standard brush sweep won’t touch it - we use power-sweeping and rotary whips to break it loose.
- Oversized flues after gas conversion. Building owners assume a simple sweep is enough, but in Tremont’s multi-fuel-transition buildings, cleaning often reveals the need for certified relining before NYC DOB will pass the new gas boiler. Old oil flues are frequently oversized for gas appliances, causing condensation and rapid creosote re-accumulation.
- Freeze-thaw spalling and joint erosion. The Bronx’s cold, damp winters drive significant freeze-thaw cycling through Tremont’s exposed brick and mortar. We often discover spalling and joint erosion during cleaning, when a sweep’s brush encounters crumbled flue tiles or breached mortar joints that can allow carbon monoxide to migrate between units.
- Limited exterior access. Dense attached housing means sweeps may need to work from basement boiler rooms through tight crawlspaces, increasing labor time. We’ve cleaned flues from the basement up, from the roof down, and through access panels cut into closet walls - whatever the building requires.

A Recent Job in Tremont
On a recent job at a 1920s rowhouse on Tiebout Avenue, we arrived to find an alley-load entry with tight clearance - our truck barely fit. Inside, the shared party-wall chimney had four flues, one still lined with crumbling terra cotta from its coal era. Using a DuraFlex relining kit, we installed a new stainless steel liner for the gas conversion, then power-swept the remaining flues. The building owner had the DOB documentation he needed, and the heat was back on that evening.
That’s the kind of job we do in Tremont. Not fancy. Just done right - and we stand behind it.

FAQs - Fireplace Services in Tremont
Yes - and we recommend a level-2 camera inspection, not just a sweep. Tremont’s coal-converted flues often contain compacted residue from multiple fuel eras, and the original terra cotta lining may be cracked or missing. We’ll show you the photos, explain what we found, and tell you whether your flue is safe for gas operation or needs relining to pass NYC DOB inspection. Call (855) 950-3861 to schedule - estimates are free.
Tremont’s dense attached housing, multi-flue party-wall stacks, and mixed-fuel residue require more time and specialized equipment than a standard suburban single-flue cleaning. We often work from basement boiler rooms through tight crawlspaces, and power-sweeping compacted coal-oil residue takes longer than clearing typical fireplace creosote. The tradeoff is thoroughness: we don’t leave until the flue is clean and documented. Call (855) 950-3861 for an exact quote for your building.
We provide the certified relining documentation and NFPA 211 compliance certificate that your plumber or general contractor needs for the NYC DOB filing. We don’t pull the permit ourselves - that’s typically your GC’s scope - but we make sure our work passes inspection the first time, so your conversion isn’t held up by chimney non-compliance. We’ve done this for dozens of Tremont buildings. Call (855) 950-3861 to discuss your timeline.
Yes - each flue is a separate passageway, and we seal and isolate the flue we’re working on. In Tremont’s shared stacks, we routinely clean individual flues while neighbors continue using their heat. We document the condition of adjacent flue openings at the chimney top and bottom as a courtesy, and we’ll note any obvious deterioration that could affect the whole stack. Call (855) 950-3861 to schedule your flue cleaning.
You’ll know because we’ll show you the camera footage and explain it in plain English. Signs that relining is necessary include: crumbled or missing terra cotta tiles, visible gaps or breaches in the flue wall, an unlined masonry flue serving a gas appliance, or an oversized flue causing condensation and rapid soot re-accumulation. In Tremont’s pre-war buildings, we find one or more of these conditions in roughly half the multi-unit stacks we inspect. If relining is needed, we’ll quote the DuraFlex stainless steel liner installation upfront - no pressure, no surprises. Call (855) 950-3861 and we’ll walk you through what we found.
