We offer 15+ years of experience in the Foundation and Basement Waterproofing industry. We've established a solid reputation serving residential homes in the greater Philadelphia and surrounding areas. We are committed to providing a personalized service for each individual project we take on. We look forward to building strong, long-term relationships with our clients..

"This company customer service skills and communication are horrid. I had no problem scheduling an appt for someone to sell me on their business but they day the work was to be done, I had to call them 5x for ETA checks on their techs. They were supposed to arrive between 9-9:30am and did not arrive until 1:15pm. Each time I called about the tech ETA, I was told by the receptionist that they would check and call me right back, they never did. The 5th time the receptionist said the supervisor of the techs said they were dispatched to my location early that morning, but he does not know where they are or why they did not show up. The receptionist called back later to say the techs should arrive by 12pm but they did not arrive until 1:15pm. When the techs arrived, I found that their supervisor told them to do a job prior to coming to my location. I was supposed to receive a lifetime warranty for the work done and after 4 calls I still have not received it. Poor customer service."

Basement Leak Repair questions, answered by experts

Many prevention methods can be used individually or in combination to waterproof your basement. Some of the most common waterproofing methods include:

  • Using dehumidifiers 

  • Silicate concrete sealers

  • Vapor barriers 

  • Baseboard channels 

  • Drain tile systems

  • Waterproofing paint

  • Drainage systems

  • Epoxy injection

  • Interior French drains

  • Exterior excavation and waterproofing

  • Cement waterproofing

  • Weep tiles

  • Liquid membrane

  • Sheet membrane 

  • Yard grading

  • Gutters and downspouts

When a backflow valve fails, wastewater will flow back into your system, contaminating your drinking water. You’ll immediately notice backflow valve failure from a rotten smell and brown water coming from faucets. Get in contact with a septic pro or a plumber immediately if you suspect this has happened to you.

The cost of installing landscape drainage with the help of a professional can vary widely depending on factors like the scope of the project, your location, and the specific services needed. Smaller tasks, such as installing a French drain, may range from $10 to $50 per linear foot, while more extensive projects like installing a catch basin can cost several thousand dollars to tens of thousands. Obtaining multiple quotes from qualified professionals is recommended to get a precise estimate for your specific drainage issue.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.
