Lansdowne's Basement Experts

Basement Systems USA is the local, family owned contractor in Lansdowne for waterproofing, crawl space repair and mold removal. With over 75 years combined experience and a full-time, professional staff we are ready to serve you and improve your home. 

Basement Waterproofing & Crawl Space Repair

Flooding, water seepage or even high humidity can quickly result in mold growth and water damage in your basement or crawl space. We prevent this from happening by installing an interior drainage system in the basement that is connected to a high volume sump pump. Any water that makes it to the basement is collected and pumped out of the home without you even noticing. 

Just like the basement, in the crawl space we similarly place a sump pump system and dehumidifier to prevent water issues. The entire area is encapsulated with vapor barrier to prevent mold growth. Our crawl space system comes with a 25-year warranty. 

We Provide:
  • Basement Waterproofing
  • Crawl Space Encapsulation
  • Exclusive, Patented Products
  • Humidity Control
You Receive:
  • Permanently Dry Basement
  • Clean Protected Crawlspace
  • Protection against Mold
  • Improved Home Value

If the walls of the basement or bowing inwards we install wall anchors or braces to straighten the walls. If the floor above the crawl space is sagging we install SmartJack support jacks to raise the floor back to a level position. Our Lansdowne waterproofing systems come with life-time warranties.

The walls of this customers basement was allowing water to intrude when it would rain and when action was not taken, mold began to grow. Here is where Basement Systems USA comes in the picture. 

After evaluating the basement we decided the best solution for this wet basement would be to install Waterguard around the perimeter of the basement, a CleanSpace vapor barrier a SuperSump pump and a Sanidry dehumidifier.
