We’ve been working on the pre-war brick apartment buildings that define this neighborhood for decades. The 5- and 6-story walk-ups along Sedgwick Avenue and the elevator buildings near Jerome Avenue aren’t abstract housing types to us. We know how their shared chimney stacks were built, how they’ve been modified, and why the original clay tile flue liners - sized for coal, adapted for oil, now struggling with gas - create problems that a technician from outside the Bronx simply won’t recognize. Regular Chimney Cleaning & Sweep - University Heights maintenance helps prevent the hazardous buildup these conversions often cause. When you’re dealing with a leaking crown above a multi-unit stack or deteriorating mortar joints after another hard January freeze, you want someone who has seen that exact building before.
Our trucks carry the materials to handle most repairs on the spot. No waiting for parts, no return visits that stretch across weeks. That’s how we’ve worked since 1984, and it’s how we still operate in University Heights today.

Then we tell you exactly what it costs to fix.

Our technicians are background-checked, uniformed, and trained to complete most repairs in a single visit. The estimate we give is the number on the invoice. We’ve found that in University Heights, where many residents have owned their co-ops for twenty-plus years and remember every contractor who ever let them down, this straightforwardness matters more than any marketing claim.
Our Chimney Repair Services in University Heights
Mortar Repointing
The freeze-thaw cycles that hit University Heights every January and February don’t forgive sloppy mortar work. Water seeps into deteriorated joints, expands when temperatures drop below freezing for sustained stretches, and pops out chunks of bedding mortar. Our repointing matches the original mortar composition and compressive strength of your pre-war brick, using professional-grade materials from Copperfield and Olympia Chimney. We grind out the failed joints to proper depth, never the quick surface smear that fails in two seasons. On shared stacks serving multiple units, we coordinate access to minimize disruption to tenants.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is epidemic on University Heights chimney stacks where water has entered through cracked crowns or failed cap joints. Once the freeze-thaw damage reaches the brick body, superficial fixes won’t stop it. We remove spalled units, source matching brick where possible, and rebuild with proper bonding patterns that respect the original construction. For buildings along the Grand Concourse corridor and surrounding streets, we’ve developed relationships with suppliers who stock the darker iron-spot brick common to this era of Bronx construction.
Chimney Waterproofing
University Heights’s exposure to driving winter winds off the Harlem River accelerates water penetration in masonry that already endured 80-100 years of weathering. Our waterproofing uses vapor-permeable sealers from HeatShield that allow the chimney to breathe and dry while blocking liquid water entry. We apply this after all structural repairs are complete, never as a cover-up for active deterioration. On multi-family buildings, we also assess whether the original clay tile liners are generating condensation that wets the masonry from inside - a common issue when oversized flues meet modern low-BTU gas appliances. When deterioration is too severe, we also provide Chimney Liner & Rebuild - University Heights services to restore safe, efficient venting.
Flashing Repair
Step flashing and counterflashing on flat-roofed University Heights apartment buildings take abuse from thermal expansion, ice damming at roof edges, and the cumulative settling of century-old structures. We fabricate and install custom flashing using DuraFlex materials, sealed with proper underlayment integration. Our inspections include the often-neglected cricket or saddle behind chimney stacks on wider buildings - a detail that many quick-fix operations skip, leading to the exact leaks that brought you here.

Trusted Brands We Service in University Heights
We don’t use builder-grade substitutes, and we don’t special-order parts that leave your chimney open to weather for weeks. Our trucks stock professional-grade materials from Famco, DuraFlex, and HeatShield - brands specified by engineers for their durability in harsh freeze-thaw climates like ours.

That means your repair starts and finishes faster, with materials rated for the temperature swings that Bronx chimneys endure every winter.
Common Chimney Repair Problems We See in University Heights Homes
- Cracked chimney crowns letting water into multi-unit flue systems. The concrete or mortar wash topping your shared stack was never meant to last a century. Once it cracks, water enters the flue cavity, accelerates clay tile liner collapse, and can damage interior plaster in multiple apartments below. We rebuild crowns with proper reinforcement and slope to shed water.
- Mortar joints failed after decades of freeze-thaw without maintenance. On pre-war buildings throughout University Heights, original lime-based mortar has simply reached the end of its service life. Repointing is not cosmetic - it restores structural integrity to stacks that can weigh several tons and serve six or more households.
- Original clay tile flues mismatched to modern gas appliances. This is the defining problem of University Heights housing stock: flues sized for coal or oil now venting low-efficiency gas equipment. The resulting condensation corrodes liners, stains masonry, and creates draft hazards. Our camera inspections document exactly what you’re dealing with.
- Flashing separation at roof-chimney intersections on flat-roofed buildings. The built-up roofing systems common to University Heights apartment blocks shift and crack at chimney penetrations. Water follows the path of least resistance into attics and top-floor units. We address the flashing, the roofing interface, and any underlying masonry damage.
