Local know-how
Why basements leak in Chester County
Chester County has one of the largest collections of historic stone homes in the country. Farmhouses, mill houses and borough homes in West Chester, Kennett Square and Downingtown often have fieldstone foundations that were never designed to keep groundwater out.
The Brandywine Creek and its branches, Valley Creek, French Creek and the Schuylkill River along the northern edge keep groundwater high in many valleys. Springs are common in the rolling countryside, and a basement dug into a hillside can intercept one.
Many newer subdivisions were built on former farmland. When the natural drainage of a field is changed, water can collect around foundations, and poured-concrete basements start showing wall cracks, damp corners and leaks around window wells and utility penetrations.

FAQ
Basement Waterproofing in Chester County
Nearby service areas:
What does it cost to waterproof a basement in Chester County?
It depends on the foundation. Crack injection often starts at a few hundred dollars, while a full interior drainage system with sump pump typically falls between $5,000 and $12,000.
Is my historic home a problem for waterproofing?
Not at all. Contractors regularly work on historic stone foundations and use methods that keep the original stone in place.
There is a spring under my house – can that be fixed?
Yes. Water from springs and high groundwater is collected with an interior drain and sump pump and pumped away from the house.
