Basement Waterproofing & Crawl Space Repair in Philadelphia 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

At this home rain water would collect at the opening of the garage and had no place to go. We installed our XL TrenchDrain system that will capture the water coming down the drive way and flow it into the WaterGuard sub-floor system. The drainage system then is connected to the sump pump which will safely pump away unwanted water. 

Job Stories From Philadelphia 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.
