Masonry is a durable construction method, but like any other building material, it is susceptible to wear and tear over time. Factors like weather exposure, moisture, and structural shifts can cause masonry issues that– if left unchecked– can lead to costly repairs.
Do you know How to Spot Early Signs of Masonry Damage? Learning about common masonry issues can help with detecting these problems early. Below, we explore some prominent masonry problems (and their solutions):
- Why do cracks form in brick and mortar?
- What is efflorescence and how do you remove it?
- Why are my bricks flaking or crumbling?
- What causes a brick wall to bow or bulge?
- When should you repoint your brickwork?
- How do you prevent water damage in masonry?
- What are the signs of chimney deterioration?
7 Common Masonry Problems and Their Solutions
1. Why Do Cracks Form in Brick and Mortar?
Problem: Cracks in brick and mortar can happen due to foundation settlement, temperature fluctuations, or poor insulation. These cracks can allow water infiltration, leading to further structural damage.
Solution: Depending on the severity of the cracks, repairs may involve tuckpointing (removing and replacing damaged mortar), sealing small cracks with masonry caulk, or (in extreme cases) replacing bricks and reinforcing the structure.
2. What Is Efflorescence and How Do You Remove It?
Problem: Efflorescence is a white, chalky deposit that forms on bricks due to moisture drawing salts to the surface. While it isn’t necessarily harmful, it can be a sign of excessive moisture within the masonry, leading to worse problems in the future.
Solution: Remove efflorescence using a dry brush or a specialized masonry cleaner. More importantly, address the moisture source by improving drainage, sealing the masonry, or repairing leaks.

3. Why Are My Bricks Flaking or Crumbling?
Problem: Spalling– flaking, peeling, or crumbling– occurs when moisture seeps into bricks, freezes, and expands, causing the surface to flake or crumble. This is common in areas with harsh winters– which we are used to here at JJB Home located in Wisconsin!
Solution: Replace damaged bricks and apply a breathable masonry sealant to prevent further water absorption. Additionally, putting proper drainage around the structure can help minimize exposure to excess moisture.
4. What Causes a Brick Wall to Bow or Bulge?
Problem: If you notice sections of a brick wall bowing outward, this could indicate water damage behind the masonry or structural instability.
Solution: A professional mason should assess the situation, as repairs may involve anchoring the wall to the structure, reinforcing it with steel ties, or even partial rebuilding to restore stability.
5. When Should You Repoint Your Brickwork?
Problem: Over time, mortar joints deteriorate due to weather exposure, leading to weakened masonry that can allow water penetration and compromise structural integrity.
Solution: Repointing– or tuckpointing– involves removing deteriorated mortar and replacing it with fresh mortar. This not only restores strength but also enhances the appearance of the masonry.
6. How Do You Prevent Water Damage in Masonry?
Problem: Water damage can proceed as staining, mold growth, or crumbling masonry due to prolonged moisture exposure.
Solution: Improve drainage by ensuring downspouts and gutters are functioning properly. Applying water-resistant coatings or sealants can also help protect masonry from excessive moisture.
7. What Are the Signs of Chimney Deterioration?
Problem: Chimneys are particularly vulnerable to masonry issues due to their exposure to harsh weather. Common problems include cracks, loose bricks, and damaged chimney crowns.
Solution: Regular chimney inspections can help catch issues early. Repairs may involve repointing mortar, sealing cracks, or installing a new chimney cap to prevent water intrusion.
How to Maintain Your Masonry for Longevity
To keep your masonry in top condition, consider:
✔ Regular Inspections: Check for cracks, spalling, or efflorescence.
✔ Proper Drainage: Ensure gutters and downspouts direct water away from masonry surfaces.
✔ Timely Repairs: Address small issues before they turn into costly repairs.
Although some of these fixes could be addressed DIY style, we highly suggest you consult a professional. JJB Home offers expert tuckpointing, brick repair, and restoration services, we can help preserve the integrity and beauty of your masonry. Contact us today to schedule!
