Gwynn Oak's Basement Experts

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

Mold Removal & Remediation

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. Unlike other mold remediation companies, our background in basement & crawlspace waterproofing allows us the make sure that the mold won't come back after it has been remediated. We are also AMA Certified.

Our Services Include :

  • Mold & dust mite control           
  • Dehumidifier Installation
  • Crawl Space Encapsulation
  • IAQ 6000 Mold Encapsulant


  • Black Mold Removal
  • Dry rot cleaning & repair

Job Stories From Gwynn Oak, MD
Waterproofing a Gwynn Oak, MD Basement

One of our customers wanted a dry basement in their home. We installed our high quality TripleSafe sump pump system, a reliable three pump system that prevents basement flooding even when the power is out. WaterGuard was also installed in order to ensure water leaking through the walls and floor will be caught and sent to the pump before any damage can be done. The customer now has a great living space in their basement where they don’t need to worry about flooding.
