Newark's Basement Waterproofing & Remodeling Contractor

Basement Systems USA is your reliable and respected basement waterproofing contractor in Newark. We also specialize in basement finishing, crawl space repair and mold removal. Our fully trained waterproofing specialists can help provide a more comfortable and safe home for you and your family. 

Basement Waterproofing & Crawl Space Encapsulation in Newark

Wet basements are as old as the structures themselves. Water will leak into a basement through any opening it can, including your walls, floors, and the joints. Water can even pass through the concrete itself -- which is one reason why basements are notoriously damp, humid spaces.

Crawl spaces are no exception. When a home is built a crawl space is ripe for humidity, mold, or pests due to the vents installed, and the common use of batt insulation. Batt insulation is a magnet for moisture and pests and can fall apart and away from the home over time. This will cause your home's temperature to become to cold in the winter and too humid in the summer. In turn, the costs of your energy bills rise.


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

At Basement Systems USA, our waterproofing systems come with life-time warranties that are transferable.  You will rest easy at night knowing that you have a dry and comfortable home.

Basement Finishing & Remodeling in Newark, 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

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

Unlike the average Newark 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.

Newark Mold Removal & Remediation

If you've had issues with mold growth in your home, you need a remedy that will completely remove the mold and prevent it from coming back. At Basement Systems USA we provide complete mold testing and removal services, and we'll ensure you have a clean, healthy home. Our years of waterproofing basements and crawl spaces give us the edge over the average mold contractor, as we can find the source of your mold problems, remediate it, which prevents the mold from ever returning. We are also AMA Certified.

Our Services Include :

  • Mold & dust mite control

Job Stories From Newark, DE
Transformed basement in Newark, DE

This Newark basement was a real mess.  The basement looked more like a dungeon and had constant water issues with dampness. We installed WaterGuard around the perimeter with a SuperSump system to take the water out of the house. Then we installed a Trench drain in front of the steps so that water could not come in from the stairwell. A vapor barrier was installed to cover the damp walls and prevent moisture from flowing into the basement. Last but not least, a SaniDry dehumidifier was installed to make sure that the basement air stays below 55% to prevent mold growth.

Wet Basement Transformed into a Beautiful, Dry, & Usable Space

This Basement required a waterproofing system with a SuperSump sum pump and Battery backup before we could finish the basement.  We also installed a SaniDry XP Dehumidifier to keep the humidity at a low level, especially to combat the humid summer months.  Once the basement was guaranteed to stay dry, the customer felt comfortable investing the money to transform the space into a finished basement.  The walls are guaranteed against mold or water damage.  The floor is also designed to withstand moisture and has a thermal gap under it which makes it up to 7 degrees warmer. We don’t just finish the basement, we make sure that the right materials are used to prevent mold or damage in the future.

My husband and I bought a house, just moved in. Had it inspected, and we have a minor mold problem on the basement walls, the bathroom wall upstairs, and under the sink in the kitchen. The basement is an unfinished basement. We'd like to have the mold remediated and your business popped up first. We have a 4 month old baby. So we'd love this done as quickly and as affordably as possible. Thanks!
