Why Ashby Chimney New York Is East Harlem’s Preferred Fireplace Repair Company
We’ve spent a lot of time in East Harlem buildings built before 1920, and we know what that means for fireplaces here. Many of these chimneys are original brick with clay-tile flues that were never designed for the freeze-thaw cycles they’ve absorbed for a hundred years. When we show up in East Harlem, we’re not learning the building stock for the first time.
The Kingswell Way shapes how we work in East Harlem: say the price, show up in the window, leave it cleaner, put the guarantee in writing, come back if it fails. Every job gets a written price before work starts, and every repair carries a written guarantee. If a covered repair fails within the guarantee period, we return and correct it at no charge. That’s the 365-Day Done Right Promise, and it’s not an add-on we try to sell you. It’s just how we work.
Nathan Corliss leads our team, and he’s built the company since 2002 on a simple idea: show the homeowner the problem before asking for money. When we quote a repair in East Harlem, we show you the camera evidence first. You should never pay for a liner or a firebox rebuild on someone’s word alone.
Styles & brands we work with





Wood Stove Installation in East Harlem
Wood Stove Installation in East Harlem is a bigger job than most people expect, and the honest price range here is $2,400 to $5,800 for a typical install with a new stainless steel liner. East Harlem’s older walk-ups often have chimneys that were built for open fireplaces, not airtight stoves, so the flue size and condition usually determine whether an install is straightforward or requires liner work first.
Liner Requirements in Pre-War Buildings
Most pre-1920 East Harlem chimneys have clay-tile liners that are cracked or missing sections entirely. A wood stove needs a continuous, properly sized liner to draft safely and keep combustion gases inside the flue. We typically install a DuraFlex stainless steel liner in these buildings, sized to the stove and run from appliance to cap. We’ll show you the camera footage of the existing flue before we recommend anything.
Clearances and Permit Reality
Many East Harlem fireplaces are tucked tight into walls with combustible framing. Wood stoves require specific clearances that older tenement layouts don’t always accommodate. We measure, assess, and tell you plainly if the install can be done safely in your space. If it can’t, we’ll say so and show you why. No one should sell you a stove that can’t vent properly.
Gas Fireplace Repair in East Harlem
Gas Fireplace Repair in East Harlem typically costs between $160 and $420 for most common problems, and we’re usually out within a few days of your call. Gas fireplaces here fail in predictable ways: pilot lights that won’t stay lit in older units, thermocouples worn out from years of cycling, or burners clogged with dust from apartments that haven’t been opened up in decades.
Pilot Light and Ignition Failures
A pilot light that goes out repeatedly is usually a thermocouple or thermopile issue, not a gas supply problem. In East Harlem we see older gas fireplaces installed during 1980s and 90s renovations, and those components simply wear out. We carry the common replacement parts on the truck, so most of these are fixed in one visit.

Gas Logs That Soot or Smell
If your gas logs are leaving black soot on the glass or you smell gas when the unit runs, turn it off and call us. This can point to incorrect log placement, a blocked vent, or a failing gas valve. We test gas pressure, inspect the vent run, and clean the burner ports. You get a written report of what we found and what it costs to fix before we touch anything.
Trusted Brands We Service in East Harlem
We work on the fireplaces and chimney components that East Harlem homes actually have. We service and install gas fireplaces from the major brands found in this area, and we stock repair parts from chimney-trade suppliers like Olympia Chimney, Famco, and Copperfield. When your damper cable snaps or your chimney cap rusts through on an East Harlem rooftop, we’re not ordering parts from a catalog and waiting two weeks. We keep the common items in our New York City stock room so we can return with what your chimney needs on the first follow-up trip, not the third.

AfterCommon Fireplace Repair Problems We See in East Harlem Homes
- Shared flues with crumbling clay tile. Many East Harlem tenements have one brick chimney serving two or three fireplaces, and when that clay-tile liner cracks, every unit on the stack is affected. We’ve seen mortar fall and block the smoke shelf, pushing smoke backward into a second-floor apartment while the first-floor fireplace drafts fine.
- Sealed-off fireplaces reopened with debris inside. When a new resident knocks open a decorative fireplace that’s been closed for decades, the flue is often packed with roof debris, pigeon nests, and collapsed mortar from the chimney top. This happens constantly in East Harlem’s pre-war stock, and it’s a first-cleaning scenario for us, not a mystery.
- Water-damaged fireboxes. East Harlem winters are hard on brick. Freeze-thaw cycles force water into the masonry, and when the chimney crown and flashing are original to a 1910 building, water gets behind the firebox walls. The result is cracked firebrick, rusted dampers, and spalled brick falling into the firebox.
- Rusted damper assemblies in multi-unit buildings. Dampers in East Harlem’s older walk-ups are often original cast iron, and they rust in place from humidity and decades of disuse. A damper that won’t open properly forces smoke back into the apartment, and a damper that won’t close lets heated air and pests down into your living room.

FAQs About Fireplace Repair in East Harlem
East Harlem’s tenement stock was built when coal and wood heat were standard, but as buildings converted to oil and gas boilers in the mid-20th century, the decorative fireplaces were sealed off because they were no longer needed and building owners didn’t want to maintain them. If you reopen one, do not light a fire until the flue has been inspected. We’ve pulled pigeon nests, collapsed mortar, broken bricks, and even old plaster buckets out of these chimneys. A camera inspection costs you a visit fee and tells you exactly what you’re dealing with. Call (315) 644-2982 before you strike a match.
Yes, it can. Many East Harlem walk-ups built before 1920 have a single brick chimney stack with separate flue channels inside, but when the clay tile in one channel cracks or collapses, the broken pieces can fall and block the adjacent flues. Shared stacks also mean water leaks at the top affect everyone below. We repaired a fireplace in a pre-1920 tenement on East 116th Street where the clay-tile flue had cracked from decades of freeze-thaw cycles. After a Level 2 inspection with our camera, we installed a DuraFlex stainless steel liner and rebuilt the deteriorated firebox, restoring safe draft for all three units sharing that stack. If your building has one chimney serving multiple fireplaces, all of them should be inspected together, not just the one that’s smoking.
Yes, and in East Harlem this is often the best option. HeatShield is a cerfractory resurfacing material applied inside the existing flue to seal cracks and gaps without demolishing the brick. For pre-war chimneys where the clay tile is cracked but the brick around it is structurally sound, HeatShield can restore a safe flue for a fraction of what a teardown and rebuild costs. We assess whether your flue qualifies with a camera inspection first. If HeatShield isn’t the right fix, we’ll say so and show you why, and we’ll give you the written price for the proper repair.
Spalling is brick face falling away from the chimney, and in East Harlem it’s driven by freeze-thaw cycles. Water seeps into the brick’s pores, freezes, expands, and pops the face off the brick. Humid summers compound it by trapping moisture in the masonry. Spalling is dangerous because it means the chimney’s structural brick is eroding, and pieces can fall onto the roof or down the flue. If your fireplace flue runs through a spalling chimney, you may see brick chips in the firebox or feel dampness around the fireplace wall. Get it inspected before winter. Spalling only gets worse with each freeze.
We show you the camera footage. Before we recommend any repair in East Harlem, we run a camera through the flue and show you the screen with your own eyes. If the liner is cracked, you’ll see the crack. If the firebox is deteriorated, you’ll see the missing mortar. If the flue is clear and the fireplace just needs a sweep, we’ll tell you that. You never get a recommendation from us based on a technician’s word alone. That’s the Kingswell Way, and it protects you from being sold a liner you don’t need. Call (315) 644-2982 to schedule an inspection and see the evidence for yourself.
