As the summer sun beats down, temperatures aren’t the only thing that rise—so does the risk of structural concerns. One of the most common seasonal issues? Foundation cracks in summer heat. If you’re planning to buy a home during this time of year, it’s important to understand what causes these cracks, how to spot them, and what they might mean for your potential purchase.
Why Do Foundation Cracks in Summer Heat Happen?
Dry, hot conditions can cause the soil around a home’s foundation to shrink and shift. As the ground loses moisture, it contracts and pulls away from the foundation walls, removing support and leading to stress fractures or settling. This process can result in foundation cracks, especially in regions where the soil type is more reactive to moisture loss.
This isn’t just a cosmetic issue—significant movement in the foundation can affect the integrity of the entire structure.
Signs of Foundation Cracks
Not all cracks are created equal, but summer is the perfect time to inspect them. Here are a few red flags homebuyers should look for:
-
Stair-step cracks in brick or block walls
-
Diagonal cracks near windows or door frames
-
Gaps between walls and ceilings
-
Doors or windows that suddenly start sticking
-
Sloping floors or visible unevenness
Any of these signs could point to foundation cracks caused by summer heat, and they warrant a closer look during the inspection process.
