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.

AfterFast, Reliable Chimney Repair Across Midtown Manhattan
Chimney repair in Midtown Manhattan typically runs $450-$2,800 depending on whether you’re dealing with a cracked flue liner, spalled brick at the crown, or failed flashing around a pre-war chase. Most repairs in this part of the city involve gas-venting compliance work, not wood-burning fireplaces, because nearly every building here predates World War II and its chimneys were converted from coal decades ago. Our crews know the difference between a decorative firebox on Fifth Avenue and an active gas flue serving a boiler on Park Avenue. That matters when carbon monoxide is the risk and a Department of Buildings permit is part of the job. Call (516) 240-9191 for a written quote before any work starts.
Why Level Two Chimney Flushing Is Midtown Manhattan’s Preferred Chimney Repair Company
Midtown Manhattan’s chimney work looks nothing like the suburban fireplace jobs most sweep companies train for. Our technicians spend their days in pre-war co-op towers, luxury rental buildings, and landmark hotels built between 1910 and 1940, where a single masonry chase often contains six or eight separate flues, some live and some retired. We’ve completed more than 38,000 chimney inspections and cleanings since 2009, every one documented with a camera scan and a written record. In Midtown Manhattan, that record matters: co-op boards and managing agents want proof of what was found before they approve a single dollar of remediation.
Corrine Halstead built our inspection standard around one idea: show the customer what the camera sees. That’s why every visit includes a photo record under Clause 4 of the Haven Standard. We pulled DOB conversion permits on a 1928 Park Avenue co-op to map which flues were live before we touched a liner. That’s the level of detail Midtown Manhattan buildings require.
Our Chimney Repair Services in Midtown Manhattan
Mortar Repointing
Pre-war brick chases in Midtown Manhattan lose their mortar joints to wind-driven rain and freeze-thaw cycles, especially near the crown where water pools. Repointing restores the structural bond and keeps water out of the chase. Expect $25-$45 per square foot for repointing on a typical Midtown high-rise parapet or exposed chimney stack.
Spalling Brick Repair
When water gets into aged brick and the face starts popping off in flakes or chunks, that’s spalling, and it’s common on 1920s co-op chimneys along Fifth and Park Avenues. Left alone, spalled brick exposes the interior wythe to more water, which accelerates the damage. We cut out and replace spalled units, matching the existing brick as closely as the market allows. Spalling repair in Midtown Manhattan typically runs $400-$1,200 per affected area, depending on height and access.
Chimney Waterproofing
Midtown Manhattan’s urban canyon wind vortices push rain sideways into masonry at angles that suburban chimneys never experience. A breathable waterproofing treatment, applied after any needed repointing or crown work, is the cheapest way to slow the cycle. We apply siloxane-based waterproofing rated for high-rise exposure; a typical Midtown chimney chase runs $600-$1,500 to treat properly.
Flashing Repair
Flashing is the metal transition where the chimney meets the roof or parapet, and on Midtown Manhattan’s older buildings it’s often original copper or corroded galvanized steel that has pulled away from the masonry. Failed flashing is the most common cause of water staining on the top-floor ceiling directly below a chase. Flashing repair here runs $500-$1,800 depending on whether we’re re-sealing existing metal or fabricating new copper flashing on site.
We also handle full Chimney Repair scope: flue liner replacement, crown rebuilds, and partial rebuilds of damaged chases. If you’re in a Midtown co-op or condo, we coordinate with your super and managing agent so the work fits the building’s schedule and board requirements.

We install and repair flue liners from DuraFlex and HeatShield, and we use Olympia Chimney components for caps, crowns, and dampers on Midtown Manhattan buildings. Our supply chain runs through Haven’s buying network, which keeps material costs down without cutting corners on the liner itself. For a gas-venting chase in a pre-war tower, we typically recommend a DuraFlex stainless liner when the existing terra cotta has cracked under decades of acidic gas condensation.
Common Chimney Repair Problems We See in Midtown Manhattan Homes
- Abandoned coal flues left open at the crown. Buildings converted from coal to gas in the 1950s and 60s often capped the firebox but never sealed the top of the flue. Rain gets in, spalls the clay tile, and cracks adjacent active gas-venting flues inside the same chase. We pull DOB conversion permits to map which flues are live before any repair.
- Urban canyon downdrafts. The supertall buildings around Sixth Avenue and 57th Street redirect wind downward, creating vortices that push exhaust back into shorter pre-war chimneys. This appears as a gas smell or backdraft in apartments even when the flue is clean. The fix is usually a combination of a properly sized liner, a draft-inducing cap, and sometimes a powered venter, depending on the building’s Section 717 compliance status.
- Cracked terra cotta liners from 1910s-1940s construction. The original clay tile liners in Midtown’s pre-war chases were never designed for gas. Decades of acidic condensation have eaten hairline cracks into them, and those cracks let carbon monoxide migrate through shared masonry walls. A Level 2 camera scan finds these cracks before they become a CO event.
- Failed flashing at the parapet transition. On high-rise flat roofs, the flashing detail where the chimney meets the parapet is a weak point. Midtown’s wind-driven rain works its way under old flashing, staining top-floor ceilings and rotting the chase behind the brick. This is one of the most common repair jobs we do for buildings around Grand Central and Columbus Circle.

FAQs - Chimney Repair in Midtown Manhattan
Yes, most chimney repair on a Midtown Manhattan co-op requires a Department of Buildings permit, especially any liner replacement, crown rebuild, or structural work governed by NYC Building Code Section 717 for gas venting. Managing agents typically file the permit or require the contractor to pull it. We handle permit coordination as part of the written scope, and we document everything with photos so the board has a record. Call (516) 240-9191 to get the permit question answered for your specific building.
You won’t know without pulling the original coal-to-gas conversion permits from DOB, and even then, those records are sometimes incomplete. The telltale signs are a persistent gas smell near the fireplace, water staining on the ceiling below the chase, or a backdraft when the gas burner cycles on. A Level 2 camera scan maps the flues in real time and shows which are capped, which are open at the crown, and which are actively venting. If you smell gas in a Midtown Manhattan apartment, treat it as an emergency and call Con Edison first, then call us for the inspection.
Yes. We schedule most high-rise repairs through the building’s super or managing agent, and we keep the work contained to the chase, the roof, or the mechanical room, not individual units. For residents who are home all day, the main concern is carbon monoxide, which is exactly why we recommend a camera scan before any repair and a CO detector in every unit that shares a masonry chase with a gas appliance. Call (516) 240-9191 and we’ll work with your building to schedule around the least disruption possible.
Before you leave for the summer, book a Level 2 camera inspection so you know the flue is clear and the liner is intact. If your building has a decorative fireplace that’s never used, make sure the gas valve is fully shut and the damper is closed, and ask your super to confirm the crown seal hasn’t failed. Summer humidity and rain are what cause the spalling and liner cracks we find in the fall. If we find an issue in May, it’s a lot cheaper to fix it than to wait until October, when every building in Midtown Manhattan books repairs at once.
A gas smell near a decorative fireplace usually means the sealed firebox is leaking, the gas line valve at the firebox is failing, or the abandoned flue behind the firebox is open at the crown and drafting exhaust from another appliance back into your unit. On a Park Avenue co-op built in 1928, our crew traced a persistent gas odor to a retired coal flue that had been capped at the firebox but left open at the crown, allowing decades of rain to spall the clay tile and crack the adjacent active flue liner serving the building’s gas boiler. We pulled the original 1950s coal-to-gas conversion permit from DOB, identified the live flue, and rebuilt the abandoned flue’s crown while installing a DuraFlex stainless liner in the active one, resolving the backdraft and eliminating the CO risk. If you smell gas in Midtown Manhattan, evacuate, call Con Edison, then call us at (516) 240-9191 for the camera inspection.
