If you’re managing a 4–6 story brick building near Willis Avenue, East 138th Street, or along the Grand Concourse corridor, call us at (866) 884-9512 for a free estimate — Robert Garcia, our owner and lead technician, will walk the roof with you and show you exactly what’s failing.
We’ve worked on chimney stacks throughout the 10454 ZIP code for 17 years. Mott Haven’s housing stock doesn’t forgive guesswork. These 1890s–1920s brick tenements and rowhouses were built for coal, converted to oil, then converted again to gas — and their chimneys carry the scars of every fuel change. Our Chimney Liner & Rebuild team knows the difference between a flue that needs a stainless steel liner and one that needs partial masonry reconstruction because we’ve inspected hundreds of them in this neighborhood.
Why Apex Chimney Cleaning Greater New York Is Mott Haven’s Preferred Chimney Liner & Rebuild Company
Robert Garcia handles every Mott Haven job himself — not a dispatched crew, not a subcontractor. When a landlord on Alexander Avenue calls about a draft problem affecting six units, Robert climbs the roof, drops the camera, and makes the repair decision on the spot. That accountability matters in Mott Haven, where a single chimney failure can vent combustion gases into multiple apartments.
Our reputation here is documented: 1,096 verified customer reviews averaging 4.7 stars, including scores of jobs in the South Bronx. Mott Haven customers specifically mention our response time — we’re typically on-site within 24–48 hours because we keep DuraFlex, Gelco, and Olympia Chimney materials stocked for New York City’s market. We don’t wait on shipping.
We also understand the compliance pressure Mott Haven landlords face. NYC’s multiple-dwelling inspection requirements make chimney maintenance a legal obligation, not optional upkeep. Robert knows what HPD inspectors flag and what documentation co-op boards need. That local knowledge saves our customers second visits and violation corrections.
Our Chimney Liner & Rebuild Services in Mott Haven
Stainless Steel Liner Installation
Stainless steel liners are our most common solution for Mott Haven’s converted tenement chimneys. A typical single-flue stainless install in a 4-story Mott Haven building runs $2,800–$4,200. We use DuraFlex and Olympia Chimney grade-316 stainless for gas and oil applications — the same specification commercial contractors use. In Mott Haven’s pre-war stacks, we often find the original terra-cotta flue tiles crumbled from decades of coal soot followed by acidic gas condensate. Stainless steel creates a sealed, properly-sized vent path that meets modern appliance requirements without rebuilding the entire chimney.
Flexible Liner Systems
Flexible liners solve the offset problems we see constantly in Mott Haven’s century-old construction. These brick stacks weren’t built straight — they’ve settled, shifted, and been modified by multiple heating system changes. A flexible liner navigates bends and offsets that rigid pipe cannot. In Mott Haven’s tighter rowhouse flues, flexible systems often mean the difference between a working liner and a full masonry rebuild. We size them precisely; an undersized flexible liner in a gas boiler flue creates the same draft and condensation problems as no liner at all.
Liner Replacement
Not every “liner job” is a first-time install. We replace failed liners in Mott Haven regularly — previous installations that cracked, separated at joints, or were sized wrong for the current appliance. A botched liner replacement in a multi-unit building on Third Avenue left one of our customers with CO alarms triggering every heating season. Robert pulled the damaged aluminum liner, found it had been crushed during installation and was blocking 40% of the flue area, and replaced it with a properly-spec’d Gelco stainless system. Liner replacement in Mott Haven typically runs $3,200–$5,000 when we’re working inside an existing but failed system.
Partial Chimney Rebuild
Partial rebuilds target the failure zone without the cost of full stack reconstruction. In Mott Haven, this often means rebuilding the top 4–6 feet of a tenement chimney where freeze-thaw damage has destroyed the crown and upper flue walls, while the lower stack remains sound. A partial rebuild with new liner installation runs $4,500–$7,500 in this market. Robert evaluates whether the lower flue walls are structurally intact — if they are, partial rebuild saves thousands and preserves the building’s original masonry character.

Trusted Brands We Service in Mott Haven
We install professional-grade materials from Gelco, Olympia Chimney, and Famco — brands that commercial chimney contractors specify, not hardware-store generics. For Mott Haven customers, this means we don’t order parts when you call; we already stock the common diameters and adapter configurations for New York City’s typical boiler and water heater setups. A Famco stainless cap or Gelco liner kit ships from our Bronx inventory, not a warehouse three states away. That inventory position is why we can often start Mott Haven liner jobs within a week of estimate approval.
Common Chimney Liner & Rebuild Problems We See in Mott Haven Homes
- Crumbling terra-cotta flue tiles from coal-era chimneys. Mott Haven’s original flues were built for coal combustion temperatures and never designed for the cooler, more acidic exhaust of modern gas boilers. We regularly find terra-cotta reduced to loose shards that block the flue and allow exhaust to leak into adjacent channels.
- Uncapped abandoned incinerator flues filling with debris. Since NYC banned building incinerators in 1994, these secondary flues sit open to rain, leaves, and pigeon nesting. The accumulated moisture accelerates mortar decay throughout the shared stack, undermining any liner installed in the active flue.
- Partial collapse in multi-flue stacks going undetected. In a dense 4-flue tenement chimney, a failure in one flue can shift load and crack neighboring flue walls. Tenants smell “something from the boiler” — it’s actually exhaust migrating through cracked partition walls between flues.
- Freeze-thaw spalling on exposed brick stacks. Mott Haven’s position between the Harlem River and Bronx Kill means persistent ambient humidity. Combined with NYC’s hard freeze cycles, this moisture penetrates crown mortar and liner seals, then expands and fractures them from within.

FAQs — Chimney Liner & Rebuild in Mott Haven
That second flue was a building incinerator vent, required by code until NYC banned new incinerators in 1994. In Mott Haven’s 1890s–1920s tenements, these incinerator flues run parallel to the boiler flue in the same chimney stack, sharing partition walls. After 30+ years of abandonment without inspection, they’ve become a hidden hazard — debris accumulation, moisture intrusion, and mortar decay that can breach into the active flue and create CO backdraft risk. If your building has a sealed incinerator flue, Robert Garcia can camera-inspect it and recommend sealing or reconstruction to protect the active vent. Call (866) 884-9512 for an assessment — estimates are free.
You need a liner if your chimney has no liner, a damaged liner, or a liner improperly sized for your current appliance — all common in Mott Haven’s converted tenements. Warning signs include persistent soot or water stains around the boiler connection, CO detector alarms, visible terra-cotta debris in the cleanout, or a boiler that won’t draft properly on windy days near the Harlem River. Robert uses a chimney camera to verify flue condition; we don’t guess. Schedule a camera inspection at (866) 884-9512 — we’ll show you exactly what the flue looks like inside.
Yes, if the lower flue walls and chimney structure are sound. In Mott Haven’s freeze-thaw environment, damage concentrates at the crown and upper flue where exposure is worst. Robert evaluates the full stack with a camera and hammer test; when the lower 75% of the flue is intact, we rebuild from the damage point up and install a new liner through the preserved lower section. This typically saves $3,000–$6,000 versus full reconstruction. The key is honest assessment — we don’t recommend partial rebuilds when the lower stack is compromised. Call (866) 884-9512 and Robert will give you a straight evaluation.
The Harlem River and Bronx Kill create persistent ambient humidity that accelerates moisture intrusion into masonry crowns and liner systems. In winter, this moisture freezes and expands, fracturing mortar joints and liner seals faster than in drier inland neighborhoods. We see more crown failures and spalled brick in Mott Haven’s river-adjacent blocks than in comparable housing stock farther from the water. Our solution is proper crown reconstruction with slope and overhang, plus stainless steel liners that resist the acidic condensate produced when humid combustion air meets cold flue surfaces. For a humidity-specific assessment of your stack, call (866) 884-9512.
Terra-cotta tile is not a modern liner — it’s the original flue construction, and in Mott Haven’s converted tenements it’s usually cracked, improperly sized for gas appliances, or both. Gas boilers produce cooler, wetter exhaust than coal or oil; terra-cotta absorbs this moisture, cracks in freeze-thaw cycles, and allows exhaust to leak into building cavities or adjacent flues. NYC building code and NFPA 211 require listed liner systems for many appliance installations. Robert can determine whether your terra-cotta is intact and properly sized, but in 17 years of Mott Haven inspections, sound original terra-cotta suitable for unlined gas venting is rare. Call (866) 884-9512 for a definitive camera inspection.
