Crawl space care in St. Louis, MO
Across the Midwest, wet springs, snowmelt and freezing winters work on foundations all year. Water can seep into crawl spaces, freeze and thaw, and leave wood damp and floors cold. Draining and sealing the space, then insulating it, protects the structure and cuts drafts.
- Wet springsRain and snowmelt soak the soil around the foundation.
- Freeze and thawRepeated freezing can crack walls and open gaps for water.
- Cold wintersUninsulated crawl spaces make floors cold and ducts lose heat.

Yes. Pipes and ducts in an unheated, unsealed crawl space can freeze in cold snaps. Sealing the space, insulating the walls and wrapping pipes lowers the risk.
