Hockessin's Basement Experts

Basement Systems USA is the local, family owned contractor in Hockessin 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 Hockessin 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.

The customer wanted to finish the basement, but this basement needed some work done first.  First, we installed the WaterGuard waterproofing system.  Then we added CarbonArmor to repair the bowing foundation wall.  We also had to add an egress to meet code.  The we finished the basement with our TBF finishing system, which comes with a 50-year guarantee against water or mold damage.  We finished the job with some nice barn doors and our grey Thermal Plank flooring.   

Job Stories From Hockessin, DE
Waterproofing a Completely Finished Basement in Hockessin, DE

This house was for sale with a contract but failed inspection due to signs of water seepage and mold spot on the drywall.  No use doing mold remediation until you have eliminated the source of the mold, which was foundation water seepage and high levels of humidity in the basement.  This basement was complete finished with bathrooms and floor coverings.  

First we removed all the moldy carpet.  Then we cut the bottom of the wall so we could remove and haul away the moldy drywall.  Then we cut the concrete floor and installed our Waterguard system with TripleSafe Sump to stop the water seepage.  We also installed our SaniDry super dehumidifier.

Next, we re-cemented the floor and reinstallation of the bottom of the walls.  But we would never use drywall for this because drywall is very vulnerable to mold and water damage.  Instead we use TBF Everlast wall, which is non-organic and comes with a 50-year guarantee against water and mold damage.  Then we replaced the flooring with 100% waterproof flooring specifically designed for basements.  The end result is a dry, mold free, beautiful basement.

Cinder block walls have been wet in past and have white precipitate. We are interested in learning our options for getting them cleaned, perhaps treated, and/or painted.
