Kennett Square's Basement Experts

Basement Systems USA is the local, family owned contractor in Kennett Square 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 Kennett Square waterproofing systems come with life-time warranties.

At Basement Systems USA, we provide full mold remediation for basements, including air sample testing. Our company has the ability to not just remediate the mold, but also remove the source of the mold, which is moisture.

Before and After Pictures from Kennett Square

This basement had several problems. The foundation wall was starting to bow inward, so we installed CarbonArmor Straps to reinforce the wall and prevent it from continuing to bow. We also installed a TripleSafe Sump Pump along with the WaterGuard Drainage System to take care of the water that was entering the basement. To finish the job, we installed the CleanSpace vapor barrier on the walls. CleanSpace works in conjunction with WaterGuard and keeps water from entering the basement by catching any moisture that may come through the walls and directing it into the WaterGuard system where it will either evaporate or drain away into the sump.  

CleanSpace has the added bonus of brightening up your basement. It’s a fast and economical way to cover ugly basement walls. CleanSpace Wall is washable, durable and can conform to bumpy walls and it is installed using permanent drilled-in fasteners, so it stays put for a neat, clean appearance.

Over the past 2 weeks water is seeping into the one unfinished area of our basement. Enough to soak a towel when i shove it up there in 2/3 hrs. Its on a weird spot seeping in under the front door brick walkway in a corner. No rain for a week but still seeping in. I dig 2' down outside looking for cement cracks and nothing. Not a major leak but needs fixed. Thanks.
