Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Our Chimney Liner & Rebuild Services in Bushwick
Stainless Steel Liner
Most Bushwick chimneys were originally built with unlined or terra cotta clay tile flues sized for coal. That’s the situation we see on nearly every pre-1930 brick building between Maria Hernandez Park and the Jefferson Street L stop. A stainless steel liner is the standard fix. We install DuraFlex and Gelco liners, sized to the existing flue, with insulation where the code requires it. For a typical three-story Bushwick row house, a stainless liner is the most cost-effective way to bring an old flue up to current safety standards without tearing the building apart.

Flexible Liner
Flexible liners make sense when the flue has slight offsets or the existing clay tiles are still in place but cracked. We pull a flexible liner through the existing flue and connect it to your appliance. This is common in Bushwick where a gas boiler and a hot water heater are vented into the same old coal flue. The liner handles both safely.

Liner Replacement
When the old clay liner is broken beyond any safe use, the entire liner needs to come out and a new one goes in. This is the second most common job we do in Bushwick, after camera inspections. The original terra cotta liners in these 1890-1930 buildings were never designed for modern gas or wood appliances, and decades of condensation have eaten away at the mortar joints. We remove the old liner, assess the flue, and install a properly sized replacement. You’ll see every foot of it on video before we consider the job done.

Partial Rebuild
A partial rebuild usually means reconstructing the chimney above the roofline: the crown, the top few courses of brick, and the flue tile at the top. In Bushwick, we do a lot of partial rebuilds on flat-roof walkups where the crown has spalled and water has been getting into the mortar for years. We rebuild the crown with a proper wash and cap, re-point the top courses, and seal everything so water stops finding its way into the liner. A partial rebuild is often enough when the lower flue is still sound.

Common Chimney Liner & Rebuild Problems We See in Bushwick Homes
- Coal-era clay flues now venting gas or wood. Bushwick’s tenements were built for coal draft, not the lower-temperature exhaust of gas appliances. The result is condensation that eats mortar joints and cracks the tiles. A liner that worked for coal often fails within a few years of a gas conversion unless the flue is relined.
- Freeze-thaw spalling on flat-roof chimneys. New York City’s winter temperatures cross 32°F dozens of times each season. On Bushwick’s exposed rooftop chimneys, water soaks into the brick crown, freezes, expands, and spalls the brick face. The crown opens up, water drops into the flue, and the century-old clay liner below takes the hit.
- Unpermitted wood stoves in converted lofts. We see this constantly in Bushwick’s industrial-to-residential conversions. A tenant or previous owner installs a wood stove with no DOB permit and no stainless liner, vented into an old clay flue. We cannot legally clean or certify that setup. We’ll stop and walk you through the DOB approval process before any work proceeds.
- Hidden damage inside flues that look fine from the street. After the arson crisis of the 1970s and 80s, a lot of Bushwick chimneys were patched without permits. From the sidewalk, the brick looks fine. Inside, tiles are cracked, shifted, or missing. Only a camera inspection shows it. We never recommend work without showing you the footage.

FAQs - Chimney Liner & Rebuild in Bushwick
It typically needs a liner because the flue was designed for coal and has been venting gas or wood for years without maintenance. That clay tile liner was sized for hot coal draft, not the cooler, wetter exhaust of a gas furnace or water heater. Over time, condensation eats the mortar between tiles, the tiles crack, and eventually the flue stops drafting safely. In Bushwick specifically, the 1970s and 80s arson crisis meant many buildings were patched quickly and cheaply, sometimes leaving flue interiors damaged and never properly repaired. A camera inspection shows exactly what’s going on. Most of the time, the answer is a stainless steel liner. Call (516) 289-9316 and we’ll schedule the inspection.
Patching the brick face may buy you a season or two, but if the crown is spalled and water is getting into the flue, patching alone doesn’t stop the damage. Bushwick’s flat-roof chimneys are fully exposed to the freeze-thaw cycle, and a cracked crown is the entry point for water. Once water gets into the mortar joints, it freezes, expands, and pushes the bricks apart further. A proper rebuild means taking down the damaged courses, rebuilding the crown with a proper wash and cap, and sealing the top so water runs off instead of in. Patching is a temporary bandage. We’ll show you on video what the crown looks like and give you an honest recommendation either way.
No. If there’s a wood stove vented into a flue with no NYC Department of Buildings permit or no proper stainless liner, New York City code doesn’t allow us to clean or certify that chimney. Work would have to stop until the DOB paperwork is in place. We handle this situation regularly on Bushwick’s converted loft buildings. We’ll explain the process, walk you through the approval and inspection steps, and install a properly sized liner once the permit is issued. It’s not a roadblock to avoid; it’s the only way to do the job legally and safely. Call (516) 289-9316 and we’ll talk it through.
Yes. In Bushwick, the flue is the only part that matters, and you can’t see it from the street. After decades of unpermitted patching, freeze-thaw cycles, and coal-to-gas conversions, the tile liner inside a chimney that looks fine is often cracked, shifted, or partially collapsed. The camera inspection is the only way to see it without tearing the chimney open. We don’t recommend any relining or rebuild work unless the camera shows damage. This is why we include the inspection with every quote. If the flue is sound, we’ll tell you that and leave it alone.
Bushwick’s climate crosses the freezing mark dozens of times each winter, which means the exposed brick crowns on flat-roof tenement chimneys absorb water, freeze, expand, and spall. As the brick face and mortar joints open up, water enters the flue cavity and saturates the clay tile liner. When that water freezes inside the tile system, it cracks the tiles from within. Over repeated seasons, the liner shifts and gaps form. Gas exhaust and carbon monoxide can then leak through those gaps into the building. This is the single most common cause of liner failure we see in Bushwick, and it’s why we recommend an inspection before every heating season. Call (516) 289-9316 for a free estimate.
If you own a brick tenement, row house, or converted loft in Bushwick and you want a straight answer about your chimney, call (516) 289-9316. Wendell Pike will likely be the one picking up. We’ll schedule a camera inspection, show you the footage, and give you a plain-English verdict. Nothing gets recommended without proof you can see yourself. That’s how Chimney Liner & Rebuild work should always be done in this neighborhood.
