Chimney Repair in New York City
Your chimney is exposed to harsh weather every day. Rain, snow, strong winds, and changing temperatures slowly wear down bricks and mortar. Small cracks may not seem serious at first, but they often allow water to enter the structure. Over time, this can lead to larger repairs and safety concerns.
At NYC Concrete Repair, we provide professional chimney repair services for residential and commercial properties across New York City. Every project begins with a free onsite inspection so we can identify the real cause of the problem before recommending repairs.
With 25 years of masonry experience, our licensed contractors repair chimneys using proven methods and quality materials that are built to last.

Common Signs Your Chimney Needs Repair
Many chimney problems become expensive because they are ignored for too long.
Watch for signs such as:
- Cracked bricks
- Missing mortar joints
- Water stains around the fireplace
- Loose masonry
- Leaning chimney
- Pieces of brick falling from the chimney
- White staining on brick surfaces
- Rust around flashing
- Visible cracks in the chimney crown
If you notice any of these issues, scheduling an inspection early can help prevent more extensive repairs.
Why Chimneys Deteriorate
A chimney sits above the roofline where it receives constant exposure to weather.
Rainwater can enter through cracked mortar or damaged crowns. During winter, trapped moisture freezes and expands, causing bricks and mortar to break apart.
Older chimneys may also suffer from decades of weathering, settlement, or poor drainage around the roof.
In many cases, repairing the damaged sections early can extend the life of the chimney without requiring a complete rebuild.
Chimney Leak Repair
Water leaks are one of the most common chimney problems in NYC.
Leaks may be caused by:
- Failed flashing
- Cracked chimney crown
- Open mortar joints
- Missing chimney cap
- Damaged bricks
- Poor waterproofing
Instead of simply treating the symptoms, we identify where water is entering and repair the source of the problem.
Chimney Repointing
Mortar joints naturally wear out over time.
As mortar weakens, water enters the joints and begins damaging the surrounding brickwork.
Repointing removes deteriorated mortar and replaces it with new mortar that restores strength while helping protect the chimney from future moisture damage.
When completed correctly, repointing can significantly extend the service life of a brick chimney.
Chimney Rebuilding
Some chimneys have damage that goes beyond simple repairs.
If bricks have shifted, sections have become unstable, or the chimney no longer provides adequate structural support, rebuilding may be the safest solution.
Depending on the condition, we may recommend:
- Partial chimney rebuild
- Chimney top rebuild
- Full chimney reconstruction
During the inspection, we explain why rebuilding is recommended and what work is necessary.

Where We Work
We repair chimneys across Manhattan, Brooklyn, Queens, and the Bronx. Most of our work is on brownstones, rowhouses, and prewar apartment buildings in Harlem, Park Slope, Bed-Stuy, Astoria, Ridgewood, and Riverdale, where chimneys are older, taller, and harder to reach than in newer construction.
We also work regularly in landmark districts, so we know what the Landmarks Preservation Commission will approve before we file.
Schedule Your Free Chimney Inspection
A damaged chimney rarely repairs itself. Small cracks and deteriorated mortar continue to worsen as water enters the masonry.

Frequently Asked Questions
No. Many chimneys can be repaired if the damage is limited to mortar joints, bricks, or the chimney crown. A professional inspection helps determine whether repair or rebuilding is the better option.
White powdery stains, known as efflorescence, appear when moisture carries salts to the surface of the masonry. It is usually a sign that water is entering the chimney and should be investigated.
Many repairs can be completed during colder months, although weather conditions and temperature affect masonry work. We schedule repairs when conditions allow materials to cure properly.
A visual inspection every year is a good practice, especially after severe weather or if the chimney is used regularly. Early detection often prevents larger masonry repairs.
If the leak originates from damaged flashing, cracked masonry, or the chimney crown, repairing those components can stop water intrusion. During our inspection, we identify the exact source before recommending repairs.
Yes. We repair both active chimneys and decorative masonry chimneys that have developed structural or cosmetic damage.
Yes. We offer free onsite inspections and detailed estimates across New York City. Every estimate is based on an in-person assessment so you receive accurate recommendations and pricing.
