Why does my house seem to move with the seasons?
Expansive clay shrinks when dry and swells when wet. If your doors and cracks change between summer and spring, the soil is moving with the seasons.
Foundation Repair Dallas, TX
Dallas sits on some of the most expansive clay in Texas. Summer heat dries it and pulls it away from the slab, then rain swells it back.

Dallas clay and Dallas homes
Much of Dallas is built on dark Blackland Prairie clay and weathered shale. During a hot, dry summer this soil shrinks and cracks open, sometimes leaving visible gaps along the edge of the slab. After heavy rain it swells again. That repeated, uneven movement is the main reason foundation work is so common here.
Pre-war neighborhoods close to downtown and White Rock Lake include many pier and beam homes. Most homes built from the 1970s onward are slab-on-grade, many of them post-tensioned.
What Dallas homeowners run into
- Summer edge drop. The soil at the perimeter dries first, so corners and outside walls can sink while the center stays high.
- Seasonal doors. Doors that stick in August and close fine again in spring.
- Brick veneer cracks at corners, above windows, and along garage walls.
- Pier and beam sag in older homes, especially where crawlspace moisture is high.
- Tree roots near the slab drawing water out of the clay.
Keeping moisture even
Because Dallas clay reacts so strongly to moisture, drainage and watering matter here. Gutters that carry water away, grading that slopes away from the slab, and steady watering in long droughts can all reduce movement. See drainage and moisture control and how to water your foundation.

Frequently asked questions
Do post-tension slabs need special care during repair?
Yes. Steel tendons run through the slab, and repairs must avoid cutting them. Many Dallas homes have a stamped notice in the garage slab.
Is a small gap between the soil and my slab normal in summer?
It is common in Dallas during drought, but a large or growing gap means the soil is drying a lot. It is worth watching along with any interior signs.
