This homeowner was looking to camouflage a set of stairs in their newly finished basement. We think the outcome is awesome!

We took out this old window out and installed an egres approved window and Rockwell window well.  Work included interior drywall repair and a cover for the well.  Inside we had to install a WellDuct window well drain.  This drain takes water that might end up inside the window well and drain it into the interior drain tile system.

New Castle's Basement Waterproofing Contractor

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

Basement Waterproofing & Crawl Space Repair in New Castle

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 New Castle waterproofing systems come with life-time warranties. 

Basement Finishing & Remodeling in New Castle, DE

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 New Castle 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.

New Castle Mold Removal & Remediation

At Basement Systems USA, we provide complete mold remediation and removal for basements and crawl spaces. We thoroughly test any questionable areas for mold, and mold removal system is a proven, effective, and lasting solution. Unlike other mold remediation companies, our background in basement & crawl space waterproofing allows us to address the excess moisture that cause the mold growth and make sure that the mold won't come back after it has been remediated. We are also AMA Certified.

Our Services Include :

  • Basement Mold Removal
  • Crawl Space Mold Removal
  • Black Mold Removal
  • Dry Rot Cleaning and Repair


  • Dehumidifier installation
  • Shockwave by Fiberlock Disinfectant & Sanitizer
  • TBF Waterproof & Mold Resistant Wall Boards
  • Negative Air Machine Installation


Job Stories From New Castle, DE
Finished Basement in New Castle, DE

This basement finishing job required a lot of trenching to connect sewage pipes with the injector pit for the bathroom installation. Once that was out of the way, we were able to finish the basement with our Total Basement Finishing EverLast walls and MillCreek flooring systems. These products are a guarantee against future water damage and mold growth. The basement transformation is beautiful and looks like an entirely new space.
