Basement Waterproofing & Crawl Space Repair in Chester County

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

This Parkesburg PA customer called in to Basement Systems USA with a vertical crack in his poured foundation wall. The customer stated the owner prior to him tried to fix the crack himself, but was not properly done. We sent one of our foundation experts, Keith Miller, out to this property to inspect and work up a free, no obligation estimate. Once the proposal was reviewed, and our product and process was explained, the customer chose to move forward with the work he was quoted.

Basement Systems USA sent our certified technician, Dakota Herb, out to complete the FlexiSpan install on this poured foundation wall. Our FlexiSpan is a polyurethane polymer sealant that is warrantied to permanently seal the crack, not allowing any water to leak through and to not crack due to any natural movement of the foundation wall. 

Job Stories From Chester County, PA
Basement Waterproofing and Mold Removal in Baltimore, MD

A homeowner with a leaky basement and mold problem called us to help. We used our Spot Mold Treatment to rid the space of all signs of mold and then replaced the existing damaged walls with our TBF Everlast walls that are guaranteed to stay mold and moisture free. To keep the basement staying in great condition, we added more of our quality products. The SuperSump sump pump was installed to prevent water from getting into the home and the Cleanspace wall system, WaterGuard and DryTrak systems will be used to capture and send any leaking water to the drain as will the ThermalDry Wall System which improves the basement’s comfort and energy use. The homeowner is very happy with the improved and guaranteed dry basement.
