East Tremont’s housing stock is unlike newer parts of the Bronx. The 4-6 story brick buildings along East 178th Street, Clinton Avenue, and Southern Boulevard were built between the 1900s and 1940s, with masonry flues originally sized for coal heat. Many were later converted to oil, then gas, often without the relining that NYC DOB code requires. That history lives in your chimney walls. We know what to look for.

Our Fireplace Services Services in East Tremont
Gas Fireplace Service
Gas fireplace service is our most frequent call in East Tremont, and for a specific reason. Many pre-war tenements still have original coal-era flue tiles that are 12×12 inches or larger. A modern gas insert needs a 6-inch liner to draft properly. The oversized flue creates chronic condensation and backdraft issues because the exhaust cools too quickly and loses upward momentum. We recently serviced a 1920s brick tenement on East 178th Street where a gas fireplace insert was backdrafting into a second-floor apartment. The issue was an oversized coal-era clay flue tile that had never been relined. We installed a DuraFlex 6-inch stainless steel liner to match the insert’s requirements, restoring safe operation. If your gas fireplace smells, soots, or won’t stay lit, the flue sizing is the first thing we’ll check.
Wood Burning Fireplace
Wood burning fireplaces in East Tremont face a different challenge. The original coal-era fireboxes are often oversized for modern wood use, and decades of freeze-thaw cycles have cracked the rear firebrick panels. NYC’s winter temperature swings, especially on exposed rooftop stacks without chimney caps, accelerate spalling in the mortar joints. We inspect for cracked flue tiles, deteriorated smoke chambers, and proper clearance to combustibles. Burning wood in an unlined coal flue is a code violation and a fire hazard. We’ll tell you straight whether your system can be made safe or needs conversion.
Fireplace Insert
Fireplace inserts are popular in East Tremont as a way to gain efficiency without rebuilding the entire chimney. But inserts are not drop-in solutions. The existing flue must be lined to the insert manufacturer’s specifications, and the connection must be sealed to prevent exhaust leakage into wall cavities. In multi-unit buildings with gang flues, this work affects more than your apartment. We handle the permit documentation and coordinate with building management when needed. Our inserts are paired with liners from DuraFlex or HeatShield, sized precisely for the appliance.
Damper Repair
Damper repair in East Tremont often reveals deeper problems. The cast-iron throat damper in a pre-war fireplace may have rusted solid from decades of condensation, or the frame may have pulled away from the firebox walls as the surrounding brick deteriorated. A damper that won’t open fully starves the fire of oxygen. One that won’t close wastes heat and allows downdrafts. We repair or replace with components that fit the original opening, or we can install a top-sealing damper with a stainless steel cable if the throat is too damaged. Either way, you’ll know the cost before we start.
Firebox Repair
Firebox repair addresses the chamber where combustion actually happens. In East Tremont’s aging rental stock, we’ve seen firebox panels eroded to less than half their original thickness, with mortar joints completely missing between the bricks. Heat transfers directly to the surrounding framing. This is how chimney fires start in walls. We rebuild with refractory panels or firebrick, depending on the original construction, and we always inspect the adjacent smoke chamber and flue before closing up.
Fireplace Conversion
Fireplace conversion, oil to gas or wood to gas, requires more than capping the old fuel line. NYC DOB mandates a Level-2 inspection and flue relining on any fuel-type conversion. In East Tremont, where many buildings have already been converted once or twice without proper documentation, this means we often start with a compliance audit. We document the existing flue condition with camera inspection photos, specify the correct liner size for the new appliance, and pull the necessary permits. The work is governed by our 90-Day Done Right Promise: Krafted right, Every time, Your home first, Standing behind it.
Trusted Brands We Service in East Tremont
We stock parts and materials from the brands that professional chimney technicians trust, not builder-grade substitutes. For East Tremont’s pre-war buildings, we regularly install DuraFlex stainless steel liners for their corrosion resistance in condensing gas applications, and HeatShield cerfractory flue sealant for resurfacing cracked clay tiles when full relining isn’t required. We also source Gelco chimney caps and Copperfield flashing materials for weatherproofing exposed rooftop stacks. Having these parts on our trucks means most East Tremont jobs are completed in a single visit. No waiting for special orders, no return trips.
Common Fireplace Services Problems We See in East Tremont Homes
- Deferred chimney caps on aging rental stock. Many East Tremont buildings have gone decades without proper chimney caps. Water enters the flue, freezes in the mortar joints during NYC’s winter cycles, and expands to crack the flue tiles and spall the brick faces. The damage is often invisible from the street until a camera inspection reveals it.
- Shared gang flues in multi-unit buildings. A single masonry stack may vent four to six apartments. When the liner deteriorates or a nest blocks the flue, exhaust gases can enter neighboring units. Carbon monoxide detectors are essential, but they don’t prevent the problem. Inspection does.
- Repeated fuel conversions without relining. Coal to oil to gas, each conversion should have triggered a liner installation per DOB code. Many didn’t. The result is cracked, mismatched flue tiles that collect condensation and soot, reducing draft and increasing fire risk.
- Oversized coal-era flue tiles with modern gas inserts. The 12×12 inch clay tiles designed for coal furnaces are three to four times the volume needed for a 30,000 BTU gas insert. Exhaust lingers, cools, and condenses into acidic moisture that destroys the flue from the inside out.

FAQs - Fireplace Services in East Tremont
Yes. NYC DOB code requires flue relining on any fuel-type conversion, and East Tremont’s pre-war buildings with oversized coal-era flues are rarely compliant without it. The existing clay tiles were sized for coal or oil combustion temperatures, not the cooler exhaust of modern gas appliances. Without a properly sized liner, you’ll get condensation, corrosion, and potential carbon monoxide leakage. Call (855) 950-3861 for a free inspection and written estimate.
Your flue is almost certainly oversized for the appliance. East Tremont’s original 12×12 inch coal-era flue tiles are three to four times the volume a modern gas insert needs. Exhaust gases cool before exiting, and the moisture they contain condenses on the flue walls. Over time, this acidic moisture destroys mortar and flue tiles. A DuraFlex or HeatShield liner sized to your insert eliminates the problem. We can measure and specify the correct liner on our first visit.
Annually, without exception. In East Tremont’s multi-unit buildings, a single deteriorated liner or blocked flue creates carbon monoxide risks for entire floors. NYC Local Law 152 requires periodic gas piping inspections in certain buildings, but chimney flues fall under separate NFPA 211 standards that many landlords overlook. We document every inspection with photos and a plain-English report you can share with your insurance carrier or building management. Call (855) 950-3861 to schedule.
In East Tremont, a DuraFlex stainless steel liner installation typically runs $1,800-$3,200 for a standard 6-inch diameter in a 3-4 story tenement. Taller buildings, offset flues, or the need for additional repairs to the chimney crown or firebox add to the cost. We provide upfront pricing after camera inspection, and our $50 off repair offer applies to jobs over $250. Estimates are free.
Only if a Level-2 inspection confirms the flue is intact, properly sized for wood combustion, and has adequate clearance to combustibles. East Tremont’s coal-era fireboxes are often oversized, and the flue tiles may be cracked from decades of freeze-thaw damage. Burning wood in a damaged or unlined flue is a code violation and a documented fire cause. We’ll inspect with a camera and tell you honestly whether it’s safe or needs conversion. Call (855) 950-3861.
