What is a crawl space jack?

Crawl space jacks are a structural system used to reinforce and stabilize your home's crawl space foundation. It's installed in the crawl space, beneath the house, to provide additional support to sagging or weakened floor joists and beams.

Placing these steel support jacks throughout the crawl space helps distribute the weight of the structure more evenly and prevents settling and sagging of the floors above.

How do you know if you need crawl space jacks?

There are a few signs that tell you your crawl space needs some additional support, including:

  • Sloping floors, sometimes creating a gap between the floor and walls
  • Cracks in interior walls
  • Gaps around door frames
  • Doors and windows are hard to open
  • Gaps between existing columns and girders in the crawl space
  • Wood rot and deterioration of the floor joists
