3 Signs Your Brick Walls Are Failing—And What to Do About It
Brick walls are known for their strength and longevity—but that doesn’t mean they’re maintenance-free. Over time, weather exposure, moisture, and settling can cause brick and mortar to deteriorate. Spotting early signs of failure can help you avoid costly structural damage and keep your home or building safe and sound. Here are three common warning signs to look out for—and what you can do if you notice them.
1. Cracks in the Mortar or Bricks
Small hairline cracks may not seem urgent, but they can indicate underlying issues like shifting foundations or water damage. If left unaddressed, these cracks can widen, allowing moisture to penetrate the wall, which weakens the structure over time.
What to do: Have a masonry professional assess the damage. Depending on the severity, the solution could range from tuckpointing (replacing damaged mortar) to more extensive reinforcement.
2. Bulging or Bowed Brick Walls
If a section of your wall appears to be bulging outward or inward, that’s a serious red flag. This typically happens when moisture gets behind the bricks and weakens the bond between the masonry and the structure, or when the wall is bearing too much weight.
What to do: This is not a DIY fix. Bulging walls often require structural reinforcement or partial rebuilding. A qualified mason can identify the root cause and recommend the safest repair option.
3. Spalling or Flaking Bricks
Spalling refers to bricks that are flaking, chipping, or breaking apart. This often results from water infiltration and freeze-thaw cycles, where water inside the brick expands and contracts with temperature changes, breaking the surface apart.
What to do: Replace damaged bricks and address any water drainage issues around the home. A professional can help determine if water sealing or improved grading is necessary to prevent future damage.
