Downingtown's Basement Experts

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

This heavy retaining wall in Downington PA was bowing and tipping over, and we knew that Basement Systems’ GeoLock Wall Anchors were the best solution for the problem.  

When the GeoLock system is installed, a hole is drilled into the bowing wall in predetermined intervals, depending on the number of anchors needed. One anchor plate is then attached to the interior and exterior sides of the wall, lining up with the predrilled hole, and one end of a 9-foot galvanized threaded rod is then inserted through the hole and anchor plates until the rod protrudes slightly out of the interior wall. An anchor bolt is then screwed onto that protruding end. The other end of the rod attaches to a heavy duty earth anchor, which gets embedded into firm, stable soil away from the foundation. Once everything is in place, the anchor bolt is tightened, and the reverse pressure pulls the wall back toward its original position. At this point, the wall is stabilized and secure and no further adjustment is necessary. However, gradual tightening of the anchor bolt will continue to adjust the wall and over time, may even straighten it completely. This home in Elkton needed 10 anchors to repair the wall, and we were able to straighten it completely in one day. The GeoLock wall anchors are guaranteed for a period of 25 years.

Just completed a radon test through Alpha Energy and my level was 7.5pCi/L. My home is a split level (basement and a slab) with an addition built off of the back over an old porch. I also had my boiler removed recently and was hoping to use that chimney to run the vent through, if possible.

Water leak through basement window and sump pump replacement.

We have radon levels in our home around 4 (tested in September 2020 at 3.9 and March 2021 at 4.6). We already have a radon mitigation system in place from a previous owner that most likely needs to be serviced. However we have a crawl space in the basement that sits under our master bedroom and is not insulated at all. We'd like options to insulate that will also help with the radon mitigation.

I would like to get a quote for a basement room mold remediation & waterproofing
Project Location: Downingtown, PA
We have mold on several walls in the basement. We had someone in to provide an assessment for remediation, but they do not handle figuring out the source or prevention. We believe some of the mold is from before we replaced our gutters, but some areas are more active than others and we want to know how to prevent mold from returning. We still have the mold, so would be looking for an assessment for remediation, as well as possible work for prevention and recommendations.
