Are cracked bricks a problem?
It depends. Sometimes, you might not require repair work — but you should still hire a professional to see if the cracks in your bricks are a serious threat to your home’s foundation and structural integrity.
Cracks (particularly larger cracks) can present a problem. If you have stair-step cracks or horizontal cracks, there may be an issue with your home’s foundation. Wider cracks can also allow water to infiltrate and cause damage from freezing and thawing. Insects can also enter wider cracks and cause more problems (and headaches).
