How to Do It

Shine a flashlight across the floor to check for standing water or wet soil.
Inspect the vapor barrier for tears, gaps, or areas where it has shifted away from the walls.
Look at the insulation between floor joists for sagging or moisture staining.
Check for droppings, nesting material, or chewed wiring that indicate pest activity.
