Water is absolutely essential to life and survival…as long as it doesn’t go where it doesn’t belong. When it comes to home construction and maintenance, water is the primary enemy. As it seeps through the walls of your basement or comes up from underneath your floors (hydrostatic pressure) it not only weakens your foundation and could potentially destroy any renovation you’ve done or valuables stored in the basement, but creates a breeding ground for mold. This is when the water that is essential to life becomes a threat to your investments, health, and the health of your family.


TRU Basement Waterproofing is a leading basement waterproofing and crawls space repair contractor throughout the Greater Philadelphia area. As an exclusive dealer for patented products, we have access to warrantied services including sump pump installation as well as other industry-leading solutions that will keep your home safe during any season!

Outstanding communication between Amy and Pat. They both spoke with my wife and myself on the weekends and were very transparent through out the process. While I was not there during the replacement of the vapor barrier (among other services provided) the new owners of my old home had nothing but good things to say about the install. I would definitely recommend Tru Basement and use them again.

I am so pleased with the work done to waterproof my garage and add a sump pump. The work was done quickly and the employees left my basement very clean. All of the staff are friendly and courteous. Darin Garvey, the operations manager was very responsive to all of my questions and concerns. I highly recommend Tru Basement.
