Crawl space foundation supports under a home

Quick answer

Foundation problems after heavy rain

Heavy rain can reveal grading, gutter, drainage, crawl space, and foundation issues that stay hidden during dry weather.

What to watch

  • new water in the crawl space
  • wet foundation cracks
  • doors sticking after storms
  • soil washing away near the home

What to check

  • where downspouts discharge
  • whether soil slopes toward the foundation
  • low spots near patios, porches, and sidewalks

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
