Apex Chimney Cleaning Greater New York responds to Mott Haven calls within 24 hours because we know a compromised chimney in a multi-unit tenement isn’t just one family’s problem — it’s a building-wide safety issue.
We’ve been climbing the roofs of Mott Haven’s pre-war brick tenements for 17 years. Robert Garcia, our owner and lead technician, knows the difference between a 1920s four-flue stack on East 138th Street and a 1980s infill system three doors down.

Why Apex Chimney Cleaning Greater New York Is Mott Haven’s Preferred Chimney Repair Company
Mott Haven homeowners and landlords choose us because we understand what we’re looking at. These 4–6 story attached brick buildings, most thrown up between 1890 and 1930, carry chimney problems you’d never see in a Queens ranch or a new construction condo. Our Chimney Repair team has documented outcomes from more than a thousand customers across New York City, and that experience shows in how we approach Mott Haven’s specific failures.
Our 1,096 verified reviews average 4.7 stars — not from a lucky month, but from 17 consecutive years of showing up, diagnosing honestly, and fixing it right. Robert Garcia doesn’t send subcontractors to your roof. He’s the one on the ladder, reading the flue, deciding whether your mortar needs repointing or your stack needs rebuilding. That accountability matters in a neighborhood where a single chimney vents for an entire building.
We carry professional-grade materials from DuraFlex, Gelco, and Olympia Chimney — the same lines commercial contractors use — so we’re not waiting on parts when your boiler flue is leaking condensation into the brickwork. From routine mortar work to full chimney rebuilding, we handle it without passing you off to another specialist.
Our Chimney Repair Services in Mott Haven
Mortar Repointing
The freeze-thaw cycle hits Mott Haven hard. Dozens of hard freeze nights each winter, combined with wet nor’easters off the Atlantic, open up mortar joints in exposed brick chimney stacks faster than you’ll notice from the street. We grind out deteriorated joints and repoint with color-matched, weather-resistant mortar formulated for NYC’s aggressive climate. On tenements along Brook Avenue and Third Avenue, where the original lime mortar has turned to dust after a century, repointing isn’t cosmetic — it’s what keeps water out of your wall cavity and your flue liner intact.
Spalling Brick Repair
Spalling — when the face of a brick flakes off from freeze-thaw damage or moisture intrusion — is epidemic on Mott Haven’s pre-war chimneys. The neighborhood’s position between the Harlem River and the Bronx Kill traps ambient humidity against already-saturated masonry. We remove spalled bricks, source matching replacements when possible, and rebuild the affected courses with proper drainage and crown detailing so the problem doesn’t repeat in two winters.
Chimney Waterproofing
Waterproofing a Mott Haven chimney means more than brushing on sealant. We address the crown first — the concrete cap that sheds water away from your flue — because most tenement crowns were poured thin and have cracked long ago. Then we apply a vapor-permeable waterproofing agent that lets the brick breathe while blocking liquid water. This matters in Mott Haven’s dense housing: water that gets into one chimney stack can travel through party walls and show up three units away.
Flashing Repair
Step flashing and counterflashing where the chimney meets the roof are common failure points on Mott Haven’s low-slope and built-up roofs. We fabricate custom flashing from copper and coated steel, integrated with your existing roofing system. Robert Garcia inspects the saddle and cricket geometry himself — poor flashing design on these older buildings channels water straight into the attic space, and we’ve seen the rot that follows.
Chimney Rebuilding
When mortar repointing and spalling repair aren’t enough, we rebuild. Full chimney rebuilding in Mott Haven means working around tenant occupancy, coordinating with building management, and often shoring up a stack that was never designed for its current gas-fired load. We’ve rebuilt chimneys on East 138th Street, on Willis Avenue, and throughout the 10454 ZIP code — always with proper liner sizing for modern appliances, always with Robert Garcia directing the structural work.
Tuckpointing
For Mott Haven’s landmark-quality brickwork and decorative masonry, we offer tuckpointing that restores the original aesthetic while sealing the structure. This is specialized work on 1890s-era tenements where the original narrow mortar joints were part of the architectural intent. We match the profile and color precisely.

Trusted Brands We Service in Mott Haven
We install and work with DuraFlex, Gelco, and Olympia Chimney products — the same professional-grade materials specified by commercial chimney contractors. For Mott Haven customers, this means we don’t order parts from a catalog and hope they fit. Robert Garcia stocks common liner diameters, caps, and dampers for the multi-flue configurations found in local tenements, so your repair moves faster. When we installed that Gelco cap and stainless damper on East 138th Street, we had the hardware on the truck. No waiting. No “we’ll come back next week.”
Common Chimney Repair Problems We See in Mott Haven Homes
- Abandoned incinerator flues shedding debris into active boiler flues. NYC banned building incinerators in 1994, but Mott Haven’s tenements are full of these dead flues that were bricked over and forgotten. Over 30 years, mortar degrades, bricks loosen, and material drops into the adjacent gas flue — blocking draft and creating CO backdraft risk. We inspect both flues even when only one is active.
- Freeze-thaw mortar destruction on exposed stacks. Mott Haven’s chimneys rise above flat roofs with no windbreak. Every winter, water enters hairline cracks, freezes, expands, and widens the gap. By March, joints that looked sound in October have opened to finger-width gaps. We catch this early during inspection — before your liner starts shifting in its course.
- Unlined terra-cotta flues venting gas appliances they were never built for. These chimneys were designed for coal. Converted to oil, then to gas — but the flue was never properly resized or lined. Flue gas condensation attacks the terra-cotta from the inside out, producing sulfuric acid that corrodes the clay and stains your exterior brick. We install DuraFlex stainless liners sized specifically for your boiler’s BTU output and draft requirements.
- Crown failure allowing bulk water into multi-flue stacks. The concrete crown on a Mott Haven tenement chimney was often poured as an afterthought, sloped wrong or too thin. Once it cracks, water enters the chimney body and accelerates every other failure mode. We pour proper crowns with expansion joints and drip edges — or install pre-formed Gelco caps when the structure allows.

FAQs — Chimney Repair in Mott Haven
Mott Haven’s almost entirely pre-war attached brick tenements contain multi-flue chimney stacks that were built for coal, converted to oil, then converted to gas — almost never with proper relining. The density matters too: one failed chimney affects multiple families, and NYC’s multiple-dwelling inspection law makes this a compliance issue for landlords, not optional maintenance. Call (866) 884-9512 and Robert Garcia will walk you through what your specific building needs.
Yes — an unlined or under-lined terra-cotta flue venting a modern gas boiler will produce acidic condensation that destroys the clay from inside. We install DuraFlex stainless steel liners sized to your appliance’s output, which typically runs $2,800–$5,500 in Mott Haven depending on flue height and diameter. Converting without relining risks liner failure and CO leakage into occupied units. Call for a free inspection — we’ll show you the condition of your existing flue with a camera.
NYC’s multiple-dwelling law requires periodic inspection and safe operation of heating systems and their venting — and violations carry fines that escalate quickly. For Mott Haven landlords, this means chimney maintenance isn’t deferred-capital planning; it’s active compliance. We document our findings with written reports and photos that satisfy inspection requirements, and we schedule around your certificate of inspection deadlines. Robert Garcia has worked directly with property managers throughout 10454 to keep buildings in compliance.
Your second flue was for the building’s incinerator, banned by NYC in 1994. Even bricked-over, these abandoned flues accumulate moisture, lose mortar integrity, and can shed debris or backdraft CO into your active boiler flue — a failure mode almost never seen in suburban single-family work. We recently repaired a chimney on East 138th Street where exactly this was happening: the incinerator flue had been bricked over but never sealed, moisture migrated through porous mortar, and the adjacent gas boiler flue liner spalled. We installed a new DuraFlex liner in the active flue and sealed the incinerator flue with a Gelco cap and stainless damper. If your tenement has two flues, both need inspection — call (866) 884-9512.
Given NYC’s aggressive freeze-thaw cycle and Mott Haven’s persistent humidity from the Harlem River and Bronx Kill, we recommend annual inspection for occupied buildings and semi-annual inspection for any chimney showing prior mortar or spalling issues. Landlords with multiple-dwelling compliance obligations should align chimney inspection with their heating system certification schedule. Annual inspection catches crown cracks and mortar degradation before they become rebuilds — the difference between an $1,100 repointing and an $8,000 stack rebuild. Call (866) 884-9512 to set up a recurring inspection plan; estimates are free.
