Start outside
Clean gutters, extend downspouts well away from the foundation and regrade soil to slope away. Many “basement problems” are solved here.
Then inside
- Seal cracks and penetrations.
- Interior perimeter drains to a sump pump for persistent groundwater.
- A sump with a battery backup or water-powered backup.
- A dehumidifier to control humidity and mustiness.
When selling
Disclose known water history. Documented fixes with warranties reassure buyers.
