We’ve been working on chimneys in University Heights for 17 years, and we know the neighborhood’s buildings intimately. The 5-to-6-story pre-war brick walk-ups along Sedgwick Avenue, the attached rowhouses near Jerome Avenue, the larger apartment clusters around Kingsbridge Heights — these aren’t generic structures to us. They’re buildings with original coal-era flues that were converted to oil or gas decades ago, often without proper relining, and now they’re showing their age in ways that demand specific expertise. When you call us, you’re getting Robert Garcia, the owner and lead technician, not a rotating crew figuring out your building on the fly.
Why Apex Chimney Cleaning Greater New York Is University Heights’s Preferred Chimney Liner & Rebuild Company

Response time matters in a dense neighborhood like University Heights. We’re typically on site within 24 hours of your call, sometimes same-day for carbon monoxide backdraft emergencies. That speed isn’t just convenience — it’s safety. A compromised liner in a multi-family building serving multiple apartments can’t wait.
Our local knowledge runs deep. We know which buildings near Allerton Playground have the original unlined clay flues, which blocks face the worst wind exposure on the ridge, and how to navigate NYC Department of Buildings compliance for landlords who need documented chimney condition reports. That specificity is what separates a specialist from a generalist with a ladder.

Our Chimney Liner & Rebuild Services in University Heights
Stainless Steel Liner Installation
Stainless steel liners are our go-to solution for most University Heights buildings with deteriorated clay tile flues. The original coal-burning flues in these 1920s–1940s structures are almost always oversized for modern gas or oil boilers, creating a mismatch that traps condensation and accelerates corrosion. We install DuraFlex and Olympia Chimney stainless steel systems, properly sized to your appliance’s BTU output and venting requirements. A typical stainless steel liner installation in University Heights runs $2,200–$3,800 for a single-flue residential job, and $3,500–$5,200 for multi-flue apartment buildings. The ridge-top wind exposure here makes stainless steel’s durability especially valuable — it won’t crack like clay tile under freeze-thaw stress.
Flexible Liner Systems
Not every University Heights chimney chase is straight. In some of the older rowhouses near Fordham, offset flues or narrow chases make rigid stainless steel impractical. Flexible liners from Gelco and Famco navigate these obstacles without the demolition that rigid pipe would require. We use video inspection to map the flue path before recommending flexible versus rigid, and we never guess. Flexible liner installation in University Heights typically costs $2,800–$4,200, with the premium reflecting the specialized fitting and additional inspection time.
Liner Replacement
When an existing liner has failed — cracked, corroded, or improperly sized from a previous conversion — replacement is often the only code-compliant path forward. In University Heights, we see this constantly: a 1930s building converted from coal to gas in the 1970s with a “good enough” patch job that’s now crumbling. Liner replacement involves full removal of the failed material, thorough flue cleaning, and installation of a new system that matches modern appliance output. We recently handled a full chimney rebuild on a 1930s six-story walk-up at 2865 Creston Avenue in the Bedford Park section. The original coal-burning flues had been repeatedly patched after conversion to gas, and our crew installed a new DuraFlex stainless steel liner system, properly sized to the modern boiler output, resolving chronic condensation and carbon monoxide backdraft. Typical liner replacement in University Heights: $1,800–$3,400 for residential, $3,200–$5,800 for multi-family.
Partial Chimney Rebuild
Sometimes the liner is sound but the masonry surrounding it isn’t. Partial rebuilds address the crown, top courses of brick, and mortar joints without tearing down the entire stack. In University Heights, where wind shear off the Harlem River valley accelerates crown deterioration, this is a common middle-ground solution. We remove spalled brick and degraded mortar, rebuild the top 3–4 feet with matching materials, and install a reinforced concrete crown with proper drip edge and overhang. Partial rebuilds in University Heights run $2,500–$4,500, depending on accessibility and the extent of hidden damage we find once work begins.
Full Chimney Rebuild
When condensation has undermined the entire flue structure, or when multi-flue leak separations allow combustion gases to cross between apartments, partial repair isn’t enough. Full rebuild means dismantling the chimney to the roofline (or below, if the damage extends), reconstructing with new brick and mortar, installing properly sized liners for each appliance, and finishing with a reinforced crown. This is the most extensive service we offer, and it’s unfortunately common in University Heights’s oldest buildings. Full rebuilds typically range from $5,500–$8,500 for residential structures, and $8,000–$14,000 for larger multi-family buildings with multiple flues. Every full rebuild includes written documentation for NYC Department of Buildings compliance — essential for landlords in this neighborhood.

Trusted Brands We Service in University Heights

Our stock includes DuraFlex and Olympia Chimney stainless steel liners for durability against freeze-thaw cycling, Gelco flexible systems for complex flue geometries, and Famco and Copperfield fittings and accessories.

When we recommend a brand, it’s because we’ve installed it in buildings like yours and watched it perform through Bronx winters.
Common Chimney Liner & Rebuild Problems We See in University Heights Homes
- Condensation-induced liner cracking: Oversized clay tile flues from coal-era boiler conversions trap moisture, leading to freeze-thaw spalling. The exhaust temperature from modern gas boilers is too low to properly vent through a flue designed for coal — moisture condenses on the tile, freezes in winter, and cracks the liner from the inside out. We see this on virtually every block in University Heights.
- Wind-driven crown damage: The ridge-top location exposes parged caps to 40+ mph gusts, accelerating mortar joint erosion. University Heights sits on an elevated ridge above the Harlem River valley, exposing rooftop chimney crowns to stronger wind shear and more severe freeze-thaw cycling than lower-lying Bronx neighborhoods — this accelerates mortar joint spalling and cap cracking on already century-old masonry stacks, typically making spring the busiest inspection season after winter damage sets in.
- Leaky multi-flue chase separations: Shared flues between apartments allow combustion gases to vent into adjacent units, creating cross-contamination risks. In University Heights’s dense multi-family housing, a failed separation between flue liners can push CO into a neighboring apartment. We test for this on every multi-family inspection.
- Improper conversion patch jobs: Decades-old “fixes” where coal flues were partially lined or not lined at all for gas conversion, leaving gaps, misaligned sections, or materials rated for entirely different temperature ranges. These are time bombs, and we find them constantly in pre-war buildings near Magenta Playground and throughout the 10453 ZIP code.

What moves you within these ranges? Accessibility matters — a chimney on a 6-story walk-up with roof hatch access costs more than a 2-story rowhouse with direct ladder placement. The number of flues, the extent of hidden damage, and whether we need to coordinate with your boiler technician for appliance shutdown all factor in. We provide upfront, itemized estimates before any work begins, and we’re happy to explain exactly where your money goes. University Heights’s building density and parking constraints can add modest mobilization costs compared to suburban jobs, but we absorb what we can and quote honestly for what we can’t. Call (866) 884-9512 for your free estimate — we’ll inspect, diagnose, and price it with Robert Garcia on site.

FAQs — Chimney Liner & Rebuild in University Heights
The original coal-fired boiler flues were designed for high-temperature exhaust and were significantly larger than what modern gas or oil boilers produce. When those flues were converted without proper relining, the lower exhaust temperature couldn’t maintain adequate draft, causing moisture to condense inside the oversized clay tile. That condensation freezes in winter, cracks the tile, and creates a cycle of accelerating deterioration that we see across virtually every block in University Heights. If your building dates to the 1920s–1940s and hasn’t had a liner inspection in the last decade, you’re likely due. Call (866) 884-9512 — estimates are free, and we’ll show you exactly what your flue looks like with our video inspection.
Yes, the elevated ridge above the Harlem River exposes chimneys to stronger winds and repeated freeze-thaw cycles. We typically recommend stainless steel liners and reinforced concrete crowns to withstand these stresses. The wind shear here is measurably worse than in lower-lying Bronx neighborhoods, which means standard mortar mixes and basic crown construction don’t last. We spec higher-strength concrete with embedded mesh for crowns, and we use stainless steel over aluminum or clay for liners because it handles thermal shock and moisture without degrading. A rebuild done with these materials in University Heights should last 20+ years with normal maintenance. Call (866) 884-9512 to discuss material options for your specific building exposure.
Partial rebuild suffices if only the crown and top 3–4 feet are spalled and the liner is intact. But if condensation has undermined the entire flue or there are multi-flue leak separations, a full rebuild with new liners is usually needed to prevent CO hazards. We make this determination with video inspection and draft testing, not guesswork. In University Heights’s rowhouses, we also check whether the chimney is shared with adjoining buildings — a party-wall chimney complicates access and may require coordination with neighbors. Robert Garcia will walk you through the findings and show you the video evidence before recommending either approach. Call (866) 884-9512 for an inspection and honest assessment.
We typically respond to University Heights emergency calls within 4–8 hours for carbon monoxide backdraft or boiler red-tag situations, and within 24 hours for non-emergency liner failures. Our proximity to the neighborhood and familiarity with local building types means we don’t waste time figuring out access or parking. For multi-family buildings with tenants without heat, we prioritize same-day temporary venting solutions while scheduling permanent repairs. Call (866) 884-9512 anytime — if it’s a safety emergency, we’ll be there.
Yes, all liner installations carry a 20-year manufacturer warranty on materials plus our own workmanship guarantee on installation. Full and partial rebuilds include a 10-year workmanship warranty covering mortar, crown, and masonry integrity. The warranty is transferable if you sell the building, which adds value for University Heights property investors. We document everything in writing — no verbal promises that evaporate when you need them. Call (866) 884-9512 and we’ll include full warranty terms in your written estimate.
