Why Hearthstone Chimney Co. of New York City Is Kensington’s Preferred Chimney Liner & Rebuild Company

We’ve been serving Brooklyn homeowners for over 42 years, and Kensington’s dense blocks of 1910s-1930s brick row houses are some of the most chimney-dense territory we cover. Frank Calucci started this company in 1984 with the belief that a craftsman should explain what’s wrong, fix it, and stand behind the result - no flash, no arguing. That steady approach has earned us a strong local reputation in ZIP 11218 and surrounding blocks.

Our technicians are background-checked, uniformed, and trained to document every inspection with photos you can see and a plain-English verdict. Most liner and rebuild jobs in Kensington are completed in a single visit because we stock professional-grade materials from Gelco, Olympia Chimney, and Famco on our trucks. No waiting for parts, no return trips, no surprises on the bill.

When you call (855) 950-3861, a live person answers - not a voicemail, not a callback queue, not an app. We answer the phone 24 hours a day, 7 days a week, because chimney problems don’t wait for business hours. And every job is backed by our 90-Day Done Right Promise in writing: if it’s not right, we come back and make it right, no paperwork, no arguing.

Our Chimney Liner & Rebuild Services in Kensington

Stainless Steel Liner Installation

Kensington’s original coal-era chimneys were built for heavy, hot flue gases and rarely lined with anything more than clay tile. When those tiles crack after a century of Brooklyn freeze-thaw cycles, a stainless steel liner is the permanent fix. We install DuraFlex and Olympia Chimney stainless liners rated for oil, gas, and wood combustion, sized precisely to your boiler or fireplace flue. On East 8th Street near Caton Avenue, we lined a shared three-flue stack with a stainless steel DuraFlex liner after removing debris from two abandoned flues; the owner’s CO alarm had been triggered by gases migrating from the adjacent unit through deteriorated clay tiles. That job took one day. The liner carries a lifetime warranty, and our workmanship is covered by the 90-Day Done Right Promise.

Flexible Liner for Offset Flues

Some Kensington row houses have chimney flues with offsets or bends that rigid stainless pipe cannot navigate. For these, we use flexible stainless liners that conform to irregular masonry while maintaining full UL listing and proper draft. Flexible liners are especially useful in homes where previous repairs have partially blocked or shifted the flue path. We inspect with a Level-2 camera first, so we know exactly what we’re working with before we pull the liner. Photos you can see, a plain-English verdict - documented like an engineer, explained like a craftsman.

Liner Replacement

When an existing liner has failed completely - collapsed clay tile, rusted-out corrugated metal, or a HeatShield cerfractory coating that has reached end of life - we remove and replace it. Liner replacement in Kensington often involves more than just dropping pipe. Because these shared stacks may contain abandoned flues choked with debris, we frequently need to clear adjacent channels before the new liner can be installed safely. The cold, damp heating season drives heavy fireplace and boiler-flue use from October through April, compressing the annual creosote and soot buildup into a short, intense window. A failing liner during peak season is not a wait-and-see situation. We price liner replacement upfront, and the number on the estimate is the number on the invoice.

Partial Chimney Rebuild

Brooklyn’s coastal humidity combined with hard freeze-thaw cycles each winter accelerates mortar joint failure and brick spalling on the exposed upper sections of Kensington’s chimney stacks, which rise just above low rooflines with little overhang protection. When the crown is gone and brick is falling, a liner alone won’t save the chimney. Our partial rebuilds address the damaged section from the roofline up: new crown, proper drip edge, matching brick where possible, and a flue liner that terminates correctly above the rebuilt mass. Most partial rebuilds on a typical Kensington row house take two to three days. We protect your roof and yard, work around your schedule, and leave the site clean. Done right - and we stand behind it.

Trusted Brands We Service in Kensington

We work exclusively with professional-grade materials - no builder-grade substitutes that fail in five years. For Kensington homeowners, we stock Gelco and Olympia Chimney stainless components, plus Famco dampers and accessories, on every service truck. This means when we diagnose your chimney on Monday, we’re often installing by Wednesday. Fast turnaround matters in a neighborhood where heating season stretches from October through April and a cold snap doesn’t wait for parts to ship. Every brand we use is rated for NYC’s coastal exposure and backed by manufacturer warranties we honor without runaround.

Common Chimney Liner & Rebuild Problems We See in Kensington Homes

• Salt-laden coastal air accelerates corrosion of damper assemblies and access doors on exposed rooftop chimneys, leading to premature rust-through within 5-7 years. We replace rusted dampers with stainless or aluminum units rated for marine environments, and we inspect the flue beneath for secondary damage.
• Freeze-thaw cycles spall the brick crowns of low-rise stacks lacking overhangs, allowing water to enter and degrade the flue liner from above. A cracked crown sends water straight down the flue, destroying clay tile and rusting metal liners from the top. We rebuild crowns with proper slope and overhang to shed water.
• Shared party-wall stacks with abandoned flues create hidden channels for combustion byproducts to leak into occupied spaces, especially after repointing seals fail. Because Kensington row-house chimney stacks are built into shared party walls, a cracked or obstructed flue is never strictly one household’s problem - combustion gases and carbon monoxide can migrate laterally through compromised shared masonry into an adjacent neighbor’s home, a known failure mode that often triggers block-level inspection calls and means a technician working on one address should expect a knock from next door before the day is done.
• Original clay tiles cracked by decades of thermal cycling and partial use leave flues unlined and out of code compliance. NYC Buildings Department and FDNY codes now mandate proper lining before active use. An unlined flue is not grandfathered - it’s a violation that can block a home sale or insurance renewal.
