Local know-how
Why basements leak in Montgomery County
The Schuylkill River runs along the county’s southern edge through Pottstown, Royersford, Oaks, Norristown, Bridgeport and Conshohocken. In 2021 the remnants of Hurricane Ida pushed the river to record levels and flooded thousands of basements in these communities. Perkiomen Creek, the Wissahickon and Pennypack Creek flood in heavy storms too.
Older towns like Norristown, Pottstown, Ambler and Jenkintown have many twins and single homes built between the 1880s and 1930s on stone or brick foundations. Main Line homes in Ardmore, Narberth and Bala Cynwyd are often stone as well. These walls let water through as groundwater rises.
Newer suburbs in Blue Bell, Horsham, Harleysville and Collegeville mostly have poured-concrete basements. There the usual issues are wall cracks, leaking window wells and water under the floor slab when the water table is high.

FAQ
Basement Waterproofing in Montgomery County
Nearby service areas:
How much does basement waterproofing cost in Montgomery County?
Simple crack repairs begin at a few hundred dollars. Interior drainage with a sump pump typically runs $5,000–$12,000 depending on the size of the basement and the foundation type.
Can waterproofing protect my home from another storm like Ida?
No system can stop river floodwater from entering a home in a flood zone. For most homes, though, the water came from the ground and storm runoff – and drainage, sump pumps with battery backup and backflow prevention make a big difference.
Do you work on Main Line stone homes?
Yes. Partners work on stone foundations throughout the Main Line and older boroughs, typically with interior drainage and wall membranes.
