Fast, Reliable Chimney Liner & Rebuild Across Bath Beach

Our technicians are on the road throughout Bath Beach and the 11214 ZIP every day of the week, and a live person answers our phones 24 hours a day at (855) 950-3861.
We’ve been working on Bath Beach chimneys since the early 1980s. We know the semi-detached and attached brick row houses along Shore Parkway, the two-family conversions on Bath Avenue, and the shared-wall stacks that run up through three-story walk-ups near the Belt Parkway. These aren’t generic Brooklyn chimneys. The salt-laden air off Gravesend Bay eats mortar joints faster here than in Dyker Heights or Bensonhurst, and the original clay tile flue liners in these 1920s-1950s houses are now 70 to 100 years old. When you call us, you’re getting a crew that has seen your exact chimney configuration before and knows what the NYC Department of Buildings expects to see.
Why Hearthstone Chimney Co. of New York City Is Bath Beach’s Preferred Chimney Liner & Rebuild Company
We’ve served Bath Beach homeowners for over 42 years. Our trucks roll through the neighborhood weekly, and our technicians can name the block from a description of the chimney. That matters when you’re dealing with shared-wall row houses where one stack serves two or three units and a mistake on flue identification puts someone’s family at risk.
Our customers in Bath Beach leave reviews that mention the same things: we show up when we say we will, we explain what we found in plain English, and we leave photos they can actually understand. Our Level-2 camera inspections end with a written verdict and dated photographs, not a verbal shrug. The 90-Day Done Right Promise governs every liner and rebuild job we do in Bath Beach, in writing, with no arguing. If it’s not right, we come back.
Most Bath Beach calls reach a technician the same day or next day. Emergency calls for suspected carbon monoxide issues or collapsed flue liners get priority dispatch. We’re local enough to know that a January freeze-thaw cycle after a salt-air autumn means your crown could go from cracked to crumbling in a single season.
Our Chimney Liner & Rebuild team carries DuraFlex and HeatShield materials on every truck, so we’re not waiting on parts while your heat is off.
Our Chimney Liner & Rebuild Services in Bath Beach
Stainless Steel Liner Installation
Stainless steel liners are the standard for Bath Beach homes that have converted from oil to gas heating. The original clay tile flues in these row houses were sized for oil-fired boilers running at higher temperatures and larger flue diameters. A gas appliance needs a properly sized, smooth-walled stainless liner to vent safely and meet NYC DOB code. We install rigid and flexible stainless systems, properly insulated to prevent condensation damage in the unlined masonry cavity. A single-flue stainless liner in Bath Beach typically runs $2,800-$4,200 installed.

Flexible Liner Installation
Flexible liners are often the only practical solution in Bath Beach’s shared-wall chimneys, where offset flues, tight cleanout openings, or structural shifts in 90-year-old masonry make rigid pipe impossible to feed. We recently relined a shared chimney on a two-family row house near the Belt Parkway where the original clay tile divider between flues had collapsed, causing CO from the lower unit’s boiler to vent into the upper apartment’s flue. We installed two flexible DuraFlex liners, partitioned each flue with a new masonry divider, and rebuilt the crown with salt-resistant mortar to handle the bayside exposure. Flexible liner jobs in Bath Beach generally fall between $3,200-$5,500 depending on flue count and access.

Liner Replacement
Full liner replacement becomes necessary when clay tiles are spalled, shifted, or missing entirely, which we find in roughly half the Bath Beach inspections we perform on pre-war chimneys. The freeze-thaw cycles here exploit salt-weakened mortar, and tiles that looked sound five years ago are now crumbling. We remove the damaged liner system, inspect the masonry shell for integrity, and install a new code-compliant liner with proper top and bottom connections. Liner replacement in Bath Beach runs $3,500-$6,000 for most single-family and two-family setups.

Partial Rebuild
Partial rebuilds address the crown, the top few courses of brick, or a damaged flue wall without tearing down the entire stack. In Bath Beach, this is common after winter when salt-eroded crowns have disintegrated and water has penetrated the upper masonry. We rebuild with matching brick where possible and specify salt-resistant mortar mixes for the crown and exposed courses. Partial rebuilds with liner work typically cost $4,500-$7,500 in this market.

Full Chimney Rebuild
When the stack has shifted, the wythes have separated, or spalling brick extends below the roofline, a full rebuild is the only safe option. We’ve done full rebuilds on Bath Beach row houses where the shared chimney had deteriorated so severely that both units were red-tagged by the DOB. We rebuild to current code, install proper flue separation, and line each flue independently. Full rebuilds with new liners in Bath Beach range from $7,500-$12,000 depending on height, scaffolding needs, and party-wall coordination with adjacent owners.

Trusted Brands We Service in Bath Beach
We install DuraFlex flexible liners, HeatShield cerfractory flue repair systems, and Famco termination caps on Bath Beach jobs every week. These aren’t builder-grade substitutes. DuraFlex handles the tight offsets common in older Brooklyn chimneys without kinking or crushing. HeatShield lets us restore structurally sound clay flues that have minor cracking or joint gaps without full replacement. We stock common diameters and fittings on our trucks, so most Bath Beach liner jobs don’t wait on parts. When a specialized fitting is needed for your specific boiler or water heater connection, we source from Copperfield supply houses with next-day delivery to the city.
Common Chimney Liner & Rebuild Problems We See in Bath Beach Homes
- Clay tile flue liners cracked from decades of freeze-thaw cycling, especially after oil-to-gas conversion upsized the gas appliance flue demand. The original tiles were never designed for the cooler, wetter venting profile of modern gas equipment. Condensation forms, freezes in the tile joints, and the liner crumbles from the inside out. We find this in roughly 60% of pre-1960 Bath Beach chimneys we inspect.
- Collapsed clay tile dividers between adjacent flues in shared chimneys, leading to cross-contamination and DOB violations. In Bath Beach’s two-family row houses, it’s common to find a single masonry chimney carrying two separate flues where the original divider has cracked or collapsed over decades. Many owners are unaware until a cleaning tech runs a camera down each flue. This is both a code violation and a real carbon monoxide hazard between apartments.
- Crumbling chimney crowns and spalled brick from salt-air erosion, requiring full rebuild instead of simple liner repair. The neighborhood’s position directly adjacent to the Belt Parkway shoreline and Gravesend Bay means salt-laden marine air accelerates mortar joint erosion year-round. Winter freeze-thaw cycles then exploit the salt-weakened mortar, so technicians typically find crumbling crowns and open joints on chimneys that look structurally sound from the street.
- Improperly sized or abandoned flues after heating system upgrades, creating draft problems and code non-compliance. When Bath Beach homeowners converted from oil to gas in the 1990s and 2000s, many installers simply connected to existing flues without proper relining or sizing analysis. Those flues are now either too large for efficient gas venting or completely abandoned and open to the elements, accelerating deterioration of the entire stack.

FAQs - Chimney Liner & Rebuild in Bath Beach
You can’t tell from the street, and you often can’t tell from a standard cleaning. The only way to know is a Level-2 camera inspection where a technician runs a camera down each flue separately and documents the condition of the dividing wythe between them. In Bath Beach, we find compromised dividers in roughly one of every three shared chimneys we inspect. If yours is damaged, we can rebuild the divider and install independent liners for each flue. Call (855) 950-3861 to schedule an inspection - estimates are free.
Yes, almost certainly. NYC DOB code requires proper flue sizing and lining for the specific appliance being vented. The clay tile liner sized for your old oil boiler is almost always too large for efficient gas venting, leading to condensation, corrosion, and eventual liner failure. We inspect Bath Beach conversions regularly and install properly sized DuraFlex or HeatShield systems to bring them to code. The exact specification depends on your appliance’s BTU rating and venting configuration. Call for a free evaluation.
Sometimes, but not often in Bath Beach. The salt-air erosion here means that by the time cracking is visible from ground level, the crown masonry is typically deteriorated throughout, not just surface-damaged. We can apply a proper crown coat or rebuild with salt-resistant mortar if the underlying brick is sound. If the spalling extends below the crown or the flue walls are compromised, partial or full rebuild is the safer and longer-lasting choice. We’ll show you photos and give you a straight recommendation.
Every year if you use your chimney or venting system regularly, and immediately if you’ve had any heating system change, water intrusion, or noticeable draft problems. Given Bath Beach’s accelerated deterioration rate from salt exposure and the age of most local flue liners, annual Level-2 inspection is the prudent interval. The $89 seasonal tune-up includes a basic visual and flue check; full camera inspection is additional but recommended for chimneys over 50 years old.
We install DuraFlex flexible liners, HeatShield cerfractory repair systems, and Famco termination hardware on Bath Beach jobs. DuraFlex is our standard for the tight, offset flues common in older Brooklyn chimneys. HeatShield works well for clay flues with intact structure but deteriorated joints or minor cracking. We select the system based on what your specific chimney needs, not what we prefer to sell. Call (855) 950-3861 and we’ll walk you through the options after inspection.
