If water seeps in where the wall meets the floor, through the walls, or after every heavy rain, the usual long-term fix is an interior drainage system: a channel along the inside of the foundation that collects water and carries it to a sump pump, which sends it outside.

- Puddles along the base of the walls after rain or snowmelt
- Damp or stained walls, peeling paint, or white chalky deposits (efflorescence)
- A musty smell or mold on stored items
- Water coming through cracks or around pipes
Common solutions
- Interior drainage and sump pump: the most common whole-basement fix.
- Crack injection: for individual leaking cracks in poured concrete.
- Wall sealers and vapor barriers: help with dampness, not with flowing water.
- Exterior waterproofing: digging down to seal the outside of the wall. Most thorough, most costly.
- Gutters and grading: cheap fixes that solve more problems than people expect.
Cost
National averages for full basement waterproofing run from about $6,000 to $18,000. See the cost guide.
