When the summer sun beats down, it’s not just your lawn that suffers. Your home’s foundation could be at risk, too. Hot weather and dry conditions can quietly create structural problems that get worse over time. If you’ve noticed new cracks, sticking doors, or sloping floors, the summer heat might be to blame.
At '58 Foundations & Waterproofing, we help homeowners protect their homes from seasonal damage before it leads to costly repairs. Here’s what you need to know.
When temperatures soar and rainfall is scarce, the soil around your home dries out. In areas with clay-heavy soil, this causes shrinkage. As the ground contracts, it pulls away from your foundation, creating air pockets where soil used to provide support. This lack of support can lead to uneven floors, cracks in walls or brickwork, and gaps around windows or doors. These are signs your foundation may be settling.
Concrete is strong, but it reacts to temperature changes. In high heat, concrete expands. When it cools, it contracts. Over time, this cycle can lead to hairline cracks on foundation walls or slabs, widening of existing cracks, and surface spalling or crumbling. Even small cracks can allow water to enter and cause further damage.
After a long dry spell, a heavy summer storm can rehydrate the soil rapidly. This sudden change puts pressure on your foundation walls—especially in basements. Known as hydrostatic pressure, this force can lead to basement wall cracks, water seepage or puddles, and in extreme cases, bowing walls. The risk is higher if your home already has drainage or grading issues.
In summer, homeowners often water unevenly—some areas stay damp from sprinklers or air conditioning runoff while others dry out completely. This irregular moisture causes the soil to expand in wet areas and shrink in dry ones, putting uneven pressure on the foundation. Over time, this can result in structural weakening in dry zones, cracks forming in walls or brickwork, and tilting or shifting floors. This type of imbalance is a common cause of differential settlement.
To minimize the risk of heat-related foundation damage, start by keeping the soil around your home evenly moist. Avoid overwatering in just one area, and try to maintain consistent moisture levels, especially near the foundation. Watch for signs of movement inside your home, such as new cracks in walls, sticking doors or windows, or gaps along baseboards and trim. In basements or crawl spaces, check for moisture, musty odors, or visible mold, which may indicate structural issues.
