Fast, Reliable Chimney Cap & Crown Across Washington Heights
Chimney cap and crown repair in Washington Heights typically runs $280–$650 for standard work, with custom multi-flue caps on pre-war elevator buildings reaching $900–$1,400 — and we’re usually on-site within 90 minutes for Washington Heights calls.

The six-story brick stacks on West 181st Street, the shared flue systems running through walk-ups near Fort Tryon Park, the way Hudson River wind hits those exposed rooftops along Riverside Drive.

Gary Murphy leads every job himself.

We carry DuraFlex liner sections, Gelco cap hardware, and HeatShield crown coating on every truck — no waiting for parts to ship to 10033 while your flue takes on water.

Our Chimney Cap & Crown Services in Washington Heights
Multi-Flue Cap Installation
Washington Heights’s pre-war buildings demand multi-flue caps by default. Those 1920s six-story stacks weren’t built with single flues — they run three to six individual passages serving boiler rooms and former incinerator shafts. A single-flue cap on one opening leaves the others exposed to rain, squirrels, and downdrafts. We measure every flue on your stack, account for the oversized coal-era dimensions, and fabricate or source multi-flue caps that cover the full footprint. Most installations on West 175th Street corridor buildings run $650–$1,100 depending on flue count and whether we need to extend brackets for irregular crown profiles.
Custom Cap Fabrication
Standard catalog caps don’t fit Washington Heights’s reality. The masonry crowns on these buildings have settled, cracked, and been patched across a century of freeze-thaw cycles. Flue spacing is non-standard. Sometimes the active boiler flue sits three inches from a dead incinerator shaft that was bricked off at the roofline in 1993 — a detail the super might not even know. We template on-site, then work with Copperfield and Olympia Chimney for custom stainless or copper caps built to your stack’s actual dimensions. Custom caps for Washington Heights six-story walk-ups typically range $900–$1,400 installed. Lead time is usually five business days; we coordinate with your building’s roof access schedule.
Crown Repair
The crown — that concrete slab topping your chimney — takes the worst abuse in Washington Heights. Sitting atop the Manhattan schist ridge, these roofs catch Hudson River wind that accelerates mortar joint erosion and drives water into hairline cracks. We’ve repaired crowns on buildings where the concrete had deteriorated to gravel, exposing the brick wythe beneath to saturation and freeze-thaw damage. Crown repair in Washington Heights runs $280–$550 for partial rebuilds, $600–$950 for full crown replacement on multi-flue stacks. We use HeatShield crown coating as a finish layer on repairs — its elastomeric properties flex with thermal expansion better than standard Portland cement in this wind-exposed environment.
Crown Coating
For crowns with minor cracking but sound structural integrity, coating is the cost-effective play. In Washington Heights, where wind-driven rain hits at angles standard inland neighborhoods don’t see, we specify thicker application of HeatShield or similar professional-grade elastomeric coatings. Crown coating alone runs $180–$340 for typical six-story stacks. We don’t coat over active leaks or structural failures — that’s a waste of your money and our reputation. Gary evaluates every crown in person before recommending coating versus repair versus replacement.

Trusted Brands We Service in Washington Heights
We install and service professional-grade lines including DuraFlex, HeatShield, Gelco, and Olympia Chimney — brands chosen because they hold up to Washington Heights’s specific abuse profile, not because they’re cheapest. DuraFlex’s 316Ti stainless liners handle the acidic condensation from gas boilers running in oversized coal-era flues. HeatShield’s crown coating stays flexible in temperature swings that crack standard mortar. We stock common Gelco cap sizes and bracket hardware on our trucks for Washington Heights customers, which means most cap replacements don’t require a second trip. When a custom solution is necessary, we template with Olympia Chimney or Copperfield and coordinate delivery to your building’s receiving area — no lost packages left on Broadway sidewalks.
Common Chimney Cap & Crown Problems We See in Washington Heights Homes
- Wind-induced crown cracking from Hudson River exposure. Washington Heights sits on elevated schist, catching consistent westerly gusts that accelerate mortar joint erosion and loosen improperly secured caps. We see this weekly on buildings along Riverside Drive and west-facing exposures near Fort Washington Avenue.
- Dead incinerator flue misidentified as active. Since NYC banned apartment incinerators in 1993, supers frequently mistake the bricked-off shaft for the live boiler flue. We’ve arrived to find caps installed on dead flues while the active stack runs open to the elements — a confusion unique to this dense, pre-war housing stock.
- Multi-flue caps undersized for coal-era stacks. Catalog caps designed for modern residential flues don’t cover the oversized openings on Washington Heights’s six-story buildings. Undersized caps cause backdrafting and sooting in lower-floor apartments, especially during low-wind conditions when draft pressure is already marginal.
- Spark arrestor mesh clogged with wind-blown debris. The same Hudson River exposure that cools flues too quickly also deposits leaf litter and urban particulate on rooftop caps. We clean and inspect mesh screens during every service call — clogged arrestors restrict draft and can trigger carbon monoxide hazards in tightly sealed boiler rooms.

What moves the needle on cost: flue count (three-flue versus six-flue), access complexity (roof hatch versus ladder), whether we need to fabricate custom versus install stock, and the condition of the existing crown beneath the cap. Buildings on West 176th Street with original 1920s crowns requiring full rebuild land at the higher end. Co-ops with clear roof access and sound concrete crowns fall at the lower. We don’t quote over the phone for custom work — Gary measures in person, then delivers a written estimate with no obligation. Call (844) 660-6590 to schedule.

FAQs — Chimney Cap & Crown in Washington Heights
Because your building’s chimney stack contains multiple flues — typically three to six — serving the boiler room and former incinerator shafts, and capping only one leaves the others open to water, pests, and downdrafts. We template the full crown footprint and install multi-flue caps that protect every opening. Call (844) 660-6590 and Gary will measure your stack in person — estimates are free.
The old incinerator flue — bricked off after NYC’s 1993 ban — is frequently mistaken by supers for the active boiler flue, leading to caps installed on dead shafts while live stacks remain exposed. We verify every flue with a smoke test before recommending cap placement. We capped a five-flue stack on a 1927 elevator building on West 176th Street where the super had sealed the wrong flue — the old incinerator shaft — leaving the active boiler flue open to downdrafts. We installed a custom multi-flue copper cap from Copperfield with spark arrestor mesh, then coated the crown with HeatShield to seal wind-driven mortar erosion from the Hudson River gusts. Call (844) 660-6590 to avoid the same mistake.
Elastomeric coatings like HeatShield outperform standard cement-based products here because they flex with thermal expansion and resist wind-driven rain penetration at the hairline-crack level. Crown coating with HeatShield runs $180–$340 for typical Washington Heights stacks. Call (844) 660-6590 for an exact quote — estimates are free.
Usually yes — the oversized flue dimensions and irregular crown profiles on pre-war buildings rarely match catalog cap sizes, and an ill-fitting cap causes backdrafting and sooting in lower apartments. Custom caps range $900–$1,400 installed. Call (844) 660-6590 and Gary will template your stack on-site.
Quality stainless or copper caps last 15–20 years, but we inspect for wind loosening every 3–5 years given the Hudson River exposure on this ridge; galvanized or poorly secured caps may fail within 5–7 years. We include cap security checks with every sweep. Call (844) 660-6590 to schedule — estimates are free.
