What to watch
- seasonal cracks that open and close
- soil pulling from the foundation
- brick cracks near corners
- uneven floors after wet or dry swings
Local conditions
Clay soil and foundation movement
Clay-heavy soil can shrink during dry periods and swell when wet, putting changing pressure on foundations and crawl space supports.
Quick answer
Clay soil and foundation movement
Clay-heavy soil can shrink during dry periods and swell when wet, putting changing pressure on foundations and crawl space supports.
- seasonal cracks that open and close
- soil pulling from the foundation
- brick cracks near corners
What to check
- moisture changes around the foundation
- bare soil near the home
- drainage that keeps one side wetter than another
Use timing as evidence
Take the same photos when the symptom appears and after the next meaningful weather change. Record rainfall or dry conditions, indoor humidity when relevant, downspout behavior, and whether doors, floors, cracks, or odors change together.
Trace the path
Begin at the roof edge and high side of the lot, then follow gutters, downspouts, soil slope, hardscape, low corners, crawl space edges, and interior symptoms. The path helps distinguish a surface-water problem from a structural or plumbing condition.
Bring a repeatable record
- dated photos from fixed viewpoints
- locations that stay wet longest
- changes after rain or dry weather
- prior drainage or foundation work
- measurements and written recommendations
