Waterproofing in Houston: what to know
Houston is hot and humid for most of the year, with heavy rain events and hurricane risk from June through November. Many homes sit on slab foundations over expansive clay soil, which shrinks in drought and swells in rain.
- Heavy downpours and high water tables make drainage, grading and sealing important.
- Storm-driven rain tests windows, doors and walls; sealing and drainage limit damage.
- Clay soil holds water against foundations, so drainage and grading help keep it away.
How much does waterproofing cost?
- Basement waterproofing: $2,900 – $9,700
- Sump pump installation: $780 – $1,950
- Sump pump repair: $150 – $490
