Wallingford's Basement Waterproofing Contractor

Basement Systems USA is the local, family owned contractor in Wallingford for waterproofing, finishing, 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 in Wallingford

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
  • Structural Repair
  • Basement Egress Windows
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 Wallingford waterproofing systems come with lifetime warranties. 

Basement Finishing & Remodeling in Wallingford, PA

Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home. A newly finished basement done by your average contractor will mold and rot if there is an internal leak. You'll have to tear out your new basement! We fix this issue.

Our Products Include :
  • Waterproof, washable, insulated walls           
  • Mold-Resistant, No-Sag suspended ceiling
  • Modular carpet, tile & faux wood flooring
  • Basement egress windows

  • Energy-efficient, double-paned basement windows
  • Attractive Sunhouse basement window wells
  • French, bifold, louvre & six-paneled steel doors

Unlike the average Wallingford contractor we use completely inorganic, waterproof materials. Even if the basement floods your walls and floors will not be damaged by the water. These waterproof products are patented and are built to create an attractive finished basement that lasts a lifetime.
