5 Common Masonry Issues in NYC and How to Fix Them
New York City’s diverse architecture is rich in masonry, from classic brownstones to modern high-rise buildings. While masonry offers strength and durability, the city’s harsh weather conditions, aging structures, and dense urban environment can lead to several common masonry issues. Whether you’re a homeowner or a business property owner in NYC, it’s essential to understand these problems and know how to fix them before they escalate into larger, more costly repairs.
In this blog, we will discuss five of the most common masonry issues found in New York City and provide effective solutions to address each problem.
1. Cracks in Brick or Stone Walls
The Issue:
One of the most common masonry problems in NYC is cracking in brick or stone walls. Cracks can appear due to various reasons, including foundation settlement, temperature fluctuations, moisture infiltration, and natural wear and tear over time. New York’s freeze-thaw cycles, where water gets into cracks, freezes, and expands, are a major culprit in widening cracks in masonry.
How to Fix It:
Small cracks can often be addressed with simple repointing—removing old, crumbling mortar and replacing it with fresh mortar. However, larger cracks may indicate a structural issue requiring a more comprehensive approach, such as foundation stabilization or reinforcement. Using flexible sealants and waterproofing can prevent water infiltration, further protecting the structure from freeze-thaw damage.
Hiring an experienced masonry contractor, like Homeflex Construction Corporation, can ensure the issue is thoroughly inspected, diagnosed, and repaired with the proper materials to match your property’s aesthetics.
2. Efflorescence (White Stains on Masonry Surfaces)
The Issue:
Efflorescence is a white, powdery residue that forms on masonry surfaces when water seeps through bricks or stones, dissolving salts within the material. When the water evaporates, it leaves behind these unsightly salt deposits. This issue is common in older buildings or those exposed to excessive moisture due to poor drainage or water damage.
How to Fix It:
Efflorescence can be removed using a combination of water and mild detergent, along with gentle scrubbing. However, addressing the underlying moisture issue is key to preventing it from returning. Applying a quality sealant can help waterproof the masonry, while improving drainage around the building’s foundation can reduce water exposure.
In severe cases, it may be necessary to install or repair flashing to direct water away from the walls and prevent efflorescence from forming again.
3. Spalling (Flaking or Peeling Brick or Stone)
The Issue:
Spalling occurs when the outer layers of bricks or stones begin to flake, peel, or crumble away. This is usually due to water penetration, followed by freeze-thaw cycles that cause the masonry to break apart. Spalling is especially common in NYC buildings subjected to heavy precipitation and fluctuating temperatures.
How to Fix It:
If caught early, spalling can be managed by repairing damaged sections of the wall and applying a high-quality waterproof sealant. However, more extensive spalling may require replacing damaged bricks or stones. In some cases, entire sections of masonry may need to be rebuilt.
To prevent future spalling, improving the building’s waterproofing and ensuring proper drainage is essential. Regular inspections, especially after harsh winters, can help catch the issue before it worsens.
4. Deteriorating Mortar (Repointing Needs)
The Issue:
Mortar, the material used to bind bricks or stones together, can deteriorate over time due to exposure to the elements. In NYC, where pollution, temperature swings, and moisture are constant challenges, mortar joints can weaken and crumble. This not only affects the appearance of a building but also its structural integrity, as the masonry units may shift or loosen over time.
How to Fix It:
Repointing is the standard solution for deteriorating mortar. This involves removing the damaged mortar and replacing it with fresh material, ensuring that the new mortar matches the original in color and texture. Proper repointing restores the structural stability of the masonry and prolongs the building’s lifespan.
It’s crucial to hire a professional masonry contractor for repointing, as improper techniques or materials can lead to further damage, mismatched aesthetics, and reduced performance.
5. Bulging or Bowing Walls
The Issue:
Bulging or bowing walls occur when sections of a masonry wall push outward. This can be due to excessive moisture buildup, improper foundation support, or inadequate construction techniques. In some cases, poorly maintained walls, combined with the weight of heavy loads (such as a roof or multiple floors), can cause the masonry to shift or bulge.
How to Fix It:
Fixing bulging walls requires immediate attention, as they can indicate serious structural issues. Solutions may include reinforcing the wall with steel supports or ties, improving foundation drainage, or rebuilding the affected sections. In extreme cases, it may be necessary to replace the entire wall to ensure the building’s safety.

Mortar typically needs repointing every 20-30 years, depending on exposure to the elements. Regular inspections can help identify when repointing is needed.
3. Can efflorescence damage masonry?
Efflorescence itself is not harmful, but it indicates moisture penetration, which can lead to long-term damage if not addressed.
4. What are the signs of spalling in masonry?
Flaking, peeling, or crumbling of bricks or stones are signs of spalling, which usually occurs due to water damage and freeze-thaw cycles.
5. How can I prevent bulging walls?
Maintaining proper drainage and addressing moisture issues can prevent bulging. Regular inspections and repairs are key to maintaining wall integrity.
