Local know-how
Why basements leak in Delaware County
Delaware County is crossed by creeks running toward the Delaware River – Darby Creek, Cobbs Creek, Crum Creek, Ridley Creek and Chester Creek. Communities along them flood in big storms, and the groundwater around them stays high long after the rain stops.
Much of eastern Delco was built between the 1910s and 1950s: brick twins and rowhomes in Upper Darby, Drexel Hill, Lansdowne and Clifton Heights, and stone singles in Havertown and Swarthmore. Many of those basements have stone or brick walls and floors that let water through.
In twins and rowhomes, water can also come from the neighbor’s side through a shared wall or from old clay sewer laterals. That makes it important to have a contractor find the actual source before choosing a fix.

FAQ
Basement Waterproofing in Delaware County
Nearby service areas:
How much does basement waterproofing cost in Delco?
Smaller repairs can start at a few hundred dollars. A perimeter drainage system and sump pump for a typical Delco twin or single home often costs $4,000–$10,000.
Water comes through the wall we share with our neighbor. Can that be fixed from our side?
Usually yes. An interior drainage system catches water from any wall, including the shared one, and routes it to a sump pump.
Do you install backflow valves?
Many partner contractors install backwater valves or can refer you to a plumber, which is important in older areas where heavy rain overloads the sewer.
