We’ve been working Washington Heights chimneys for 17 years, and there’s nowhere else in the five boroughs where the housing stock demands this specific combination of skills. The neighborhood’s 5–6 story pre-war walkups and elevator buildings — most thrown up between 1910 and 1945 — share masonry chimney stacks with multiple flues feeding several units each. Original clay tile liners, where they exist, are pushing a century old. When you call us from Fort Washington Avenue or near Captain Rivera Playground, you’re not getting a dispatcher sending a subcontractor. You’re getting Robert Garcia, who has crawled more Washington Heights rooftops than he can count, and who understands why a standard sweep here often isn’t enough.
Why Apex Chimney Cleaning Greater New York Is Washington Heights’s Preferred Chimney Liner & Rebuild Company
Washington Heights homeowners and building managers know our name because we’ve earned 1,096 verified reviews averaging 4.7 stars — and a significant share come from repeat clients in this neighborhood alone. We’re not a franchise rotating anonymous crews; Robert handles the work himself, from the initial camera inspection to the final smoke test. That matters when you’re letting someone onto your roof 60 feet above Broadway.
Our response time to Washington Heights averages under 90 minutes for urgent calls — we know the grid between the Hudson and Harlem Rivers, and we don’t waste time hunting for parking near Summit Avenue Park or navigating the narrow service alleys behind West 181st Street buildings. More importantly, we understand the local failure patterns: the crosswinds off both rivers that tear apart chimney crowns, the oversized flues from converted coal boilers, the tarry oil soot hiding cracked liners in buildings that switched from #6 fuel oil to gas. Seventeen years of chimney-only focus means we’ve seen virtually every configuration these pre-war stacks can throw at us.
Our Chimney Liner & Rebuild team carries professional-grade materials from DuraFlex, HeatShield, and Copperfield — the same lines commercial contractors use — so we’re not waiting on parts when your building’s heat depends on a fast turnaround.
Our Chimney Liner & Rebuild Services in Washington Heights
Stainless Steel Liner Installation
For most Washington Heights gas conversions, we install DuraFlex stainless steel liners — 316Ti alloy for standard gas, 904L for high-efficiency condensing appliances. These flex through the offsets common in pre-war construction and handle the acidic condensate that destroys clay tile. A typical single-flue stainless install in Washington Heights runs $2,800–$4,200; multi-flue buildings near High Bridge or Hamilton Heights often see $6,000–$9,500 for complete stack relining. We size carefully — oversized flues from the coal era cause chronic backdrafting, and a liner that’s merely “close enough” won’t solve it.
Flexible Liner Systems
Tight roof hatches and narrow bulkhead doors are standard on Washington Heights walkups. Flexible liners coil through openings rigid pipe can’t manage, and our crew has threaded them down 40-foot flues with 6 inches of clearance. Flexible systems suit gas inserts and some oil-to-gas retrofits where the existing flue is structurally sound but oversized. Pricing typically falls $2,400–$3,800 per flue. We recently handled a job on West 178th Street near Hamilton Heights where roof access was so constrained that flexible was the only viable path — Robert measured the hatch himself to spec the right diameter.
Liner Replacement & Repair
Not every damaged liner needs full replacement. HeatShield cerfractory flue sealant can resurface cracked clay tile in structurally sound flues, saving Washington Heights co-op boards significant money — typically $1,800–$2,800 versus $3,500+ for new liner installation. But we don’t recommend patching when the underlying tile is spalling or the flue is actively leaking combustion gases. Our camera inspection shows you exactly what we’re seeing before you commit. In buildings that converted from #4 or #6 fuel oil to gas, we frequently find cracked liners hidden under heavy oil soot deposits — the kind of damage a basic sweep misses entirely.
Partial & Full Chimney Rebuild
When the masonry itself fails — spalled brick, deteriorated mortar joints, leaning stacks — liner work alone is throwing good money after bad. Washington Heights’s exposed ridge position between two rivers accelerates mortar decay; we’ve rebuilt crowns and upper courses on buildings near Hoe Garden where wind-driven rain had hollowed out the wythes. Partial rebuilds (crown, upper 4–6 feet, flashing) run $4,500–$8,500. Full rebuilds on multi-flue apartment stacks, including new liners, typically hit $15,000–$35,000 depending on scaffolding needs and flue count. Robert scopes every rebuild personally — no surprises halfway through.

Trusted Brands We Service in Washington Heights
We install and work with DuraFlex, HeatShield, and Copperfield products — professional-grade materials that match what commercial contractors spec for New York City’s harsh freeze-thaw cycles. We stock common diameters and termination fittings locally, so Washington Heights jobs don’t stall waiting on freight. For the cerfractory resurfacing work common in oil-conversion buildings, HeatShield’s engineered slurry bonds to existing clay tile at temperatures exceeding 2,900°F — critical when your flue is handling both legacy oil residue and modern gas combustion. Copperfield’s stainless components hold up to the salt-laden crosswinds off the Hudson and Harlem better than bargain hardware that’ll rust through in three seasons.
Common Chimney Liner & Rebuild Problems We See in Washington Heights Homes
- Two-era residue buildup in oil-to-gas conversions. Technicians working Washington Heights buildings that recently converted from #4 or #6 fuel oil to gas regularly find a heavy layer of tarry oil soot bonded to the masonry beneath newer gas-combustion byproducts — a combination that requires more aggressive cleaning chemistry and longer job times than a single-fuel flue, and that often reveals liner damage hidden under the old oil deposits.
- River-crosswind damage to crowns and mortar. Washington Heights sits on the exposed Manhattan schist ridge between the Hudson and Harlem Rivers, leaving rooftop chimney terminations subject to crosswinds from both waterfronts simultaneously; this accelerates mortar joint spalling and wind-driven rain intrusion at chimney crowns far more than in lower, sheltered parts of the borough, compressing the effective maintenance interval.
- Oversized flues causing acidic condensate destruction. The neighborhood’s pre-war brick apartment buildings feature large masonry chimney flues originally sized for coal or oil boilers — many converted to gas under NYC’s phased heavy fuel-oil elimination mandates. These now-oversized flues suffer chronic backdrafting and acidic condensate damage that demands relining assessments, not just routine sweeping.
- Hidden liner failure in shared multi-unit stacks. Shared masonry stacks serving 4–6 units often hide deteriorated or missing liners; a single visual sweep misses defects below the oil-soot layer that only reveal themselves during a relining assessment with camera inspection.

What moves you within these ranges? Flue count is the big one — a six-unit building on West 181st Street with four separate flues is a different job than a single-family rowhouse. Access matters: roof hatch width, elevator availability, whether we need scaffolding or can work from a boom. And the condition of existing masonry — if we’re threading a liner through sound brick versus rebuilding the wythes first — changes both scope and price. We don’t guess. Robert inspects with a camera, shows you the footage, and gives you a written estimate before any work starts. Estimates are free. Call (866) 884-9512.

FAQs — Chimney Liner & Rebuild in Washington Heights
It typically destroys it slowly. Gas combustion produces more acidic condensate than oil, and the oversized flue designed for coal or #6 oil can’t maintain adequate draft — so acidic moisture condenses on clay tile, freezes, and spalls the liner from the inside. Call (866) 884-9512 for a camera inspection; estimates are free.
Crosswinds off the Hudson and Harlem Rivers hit the exposed ridge simultaneously, driving rain into hairline cracks and accelerating freeze-thaw spalling. We recommend crown inspection every 2–3 years here versus 4–5 in sheltered neighborhoods. Call (866) 884-9512 to schedule.
Yes — each flue is a separate combustion path, and damage in one doesn’t predict condition in another. We inspect all flues in a shared stack during a single visit, pricing multi-flue jobs accordingly. Call (866) 884-9512 for building-wide assessment.
Absolutely — flexible systems coil through hatches as narrow as 18 inches, which is why we spec them for many walkup jobs. Robert measures access during the initial inspection to confirm diameter and length requirements. Call (866) 884-9512 to arrange.
A liner replacement typically completes in 1–2 days; a full rebuild requires 4–8 days depending on scaffolding, weather holds, and masonry curing time. We schedule around your building’s heat needs — never shut down in January without a plan. Call (866) 884-9512 to discuss timing.
