Basement Waterproofing in Philadelphia County, PA

Permanent Solutions for Rowhomes & City Properties

Philadelphia basements are as varied as the city itself—tight rowhomes, historic properties, and new builds. But they all share one problem: water intrusion. Heavy rain, older foundations, and limited yard drainage make leaks, mold, and foundation damage a constant threat in the city.

At Basement Waterproofing Specialists, we install custom waterproofing systems that work in small, tight spaces and older homes as well as modern basements. Every project is handled by our in-house crew, backed by a lifetime transferable warranty, and comes with a free inspection + 17% off this month.
