We’ve been working on the pre-war brick stacks of Washington Heights for over 42 years. Russell Haines started this company in 1984, and our technicians know the difference between a 1920s coal-converted flue on Fort Washington Avenue and a 1930s apartment stack off Broadway. That matters when you’re trying to stop water from coming through your living room ceiling before the next storm rolls across the Manhattan schist ridge.

Our Chimney Repair Services in Washington Heights

Mortar Repointing

The pre-war brick apartment buildings of Washington Heights - those 5- to 7-story walk-ups built between 1910 and 1945 - were constructed with lime-based mortars that breathe with the masonry. When that mortar crumbles, water penetrates the stack, freezes, and expands, opening wider gaps every winter. Repointing in Washington Heights means matching the original mortar composition so the wall can continue to breathe. A typical mortar repointing job on a standard Washington Heights chimney stack runs $850-$1,600.

Spalling Brick Repair

Spalling - the flaking and crumbling of brick faces - is common on north-facing chimney stacks in Washington Heights, where elevation-driven wind exposure keeps the masonry wet longer and accelerates freeze-thaw damage. We cut out spalled bricks to sound substrate and install matching replacements with proper drainage. Most spalling repairs in Washington Heights fall between $650 and $1,200 for localized damage, with more extensive rebuilding reaching $1,800-$2,800.

Chimney Waterproofing

Washington Heights sits atop the highest natural elevation in Manhattan, and its rooftop chimney stacks catch more wind and driven rain than chimneys in lower-lying neighborhoods. We apply vapor-permeable sealers formulated for historic masonry - products that block liquid water while allowing the wall to exhale moisture. Waterproofing a standard Washington Heights chimney typically costs $450-$750 and includes crown sealing and flashing inspection.

Flashing Repair

Flashing failure is one of the most common sources of interior water damage we see in Washington Heights apartment buildings, where decades of thermal cycling have loosened the metal where the chimney passes through the roof plane. We fabricate and install custom step flashing and counterflashing, sealed with professional-grade compounds. Flashing repair in Washington Heights generally runs $550-$950, with complex multi-flue configurations reaching $1,100-$1,400.

Trusted Brands We Service in Washington Heights

We stock professional-grade materials from HeatShield, Gelco, and Olympia Chimney - brands we specify because they hold up to the wind and weather exposure that comes with Washington Heights elevation. No builder-grade substitutes, no waiting two weeks for parts. When we find a compromised flue liner that needs a Chimney Liner & Rebuild - Washington Heights job, or a rusted chimney cap on a Broadway walk-up, we have the right component on the truck or can source it within 24 hours. That’s how most of our jobs finish in a single visit.

Common Chimney Repair Problems We See in Washington Heights Homes

• Abandoned coal flues converted to gas or oil. Many Washington Heights buildings still contain original terra-cotta flue liners that were repurposed when boilers converted from coal. These liners crack, spall, and occasionally collapse, blocking airflow or creating pathways for carbon monoxide. We inspect with cameras before any repair begins.
• Shared chimney stacks with multiple deteriorating flues. In the dense walk-up buildings along Broadway and Audubon Avenue, a single chimney pot often serves four to six separate apartment flues. One tenant’s “minor draft problem” frequently signals a blockage affecting the entire vertical stack.
• Crown cracks from wind-driven rain and freeze-thaw. The exposed position of Washington Heights chimneys on the Manhattan schist ridge means crowns take more direct weathering than downtown stacks. Hairline cracks become water channels, then spalls, then structural compromise.
• Decorative fireplaces with structurally unsound flues. Ornate mantelpieces in pre-war Washington Heights apartments routinely mask flues that are open to the wall cavity, missing liner sections, or packed with decades of debris from previous tenants. We assess before any cosmetic work begins.
