The foundation of your house or building should be checked for the following:

Check foundation walls, floors, concrete, and masonry for any cracking, heaving, or deterioration. Repair as necessary.

Make sure that soil against your foundation is properly graded away from your house. Soil should slope 4-6 inches away from the foundation for a distance of about 3 feet away from foundation walls. Fill in areas where water may puddle against the foundation.

Make sure that the splash pans for the roof gutter downspouts direct water at least 3 feet away from the foundation, and that the water does not drain back against the foundation.

Inspect foundation walls for signs of termites (such as evidence of tunnels or dirt bridges). Check flashing and termite shield. If you suspect termites, contact a professional exterminator.

Inspect where pipes go through the foundation (including in the garage) and caulk and seal as necessary.

If you have wood siding, be sure that no dirt, mulch, shrubs, etc. are touching your wood, as this can become an easy pathway for pests and moisture to enter your home.
