Damp crawl spaces cause mold to grow and wood to rot which can result in structural damage and will also release mold spores into your home, reducing air quality. We can transform your crawl space into a clean and dry environment.

Project manager Steve recommended a closed sub floor Drainage system called GrateDrain to redirect water from under the basement floor at the floor wall joint to the new GrateSump , the GrateSump can remove up to 2400 gallons of water per hr from the Basement. Steve also recommended a high volume dehumidifier to eliminate the high levels of moisture in the basement and to eliminate the homeowners fear of mold. Crew Foremen Dwight C Project Manager Steve C

The challenges we faced were that it was a very large basement, requiring around 240 feet of drainage system with a full vapor barrier and 3 sump pumps. Another challenge was that the floor in the lower basement was very hard to jackhammer in order to install the system.

To address this, we installed a full drainage system with a complete vapor barrier and 3 sump pumps.

Project Manager Dave was sent out to meet with the homeowners and after a short meeting he recommended an Egress Window be installed. Dave also recommended a full perimeter drainage system ( Grate-Drain ) to insure the basement stays dry for the life of the structure. Now the homeowners will have peace of mind that their new investment will be protected.

Heavy window flooding / The homeowners got created with this drain

Project Manager Steve Custus went out and solved this problem a few 100 times before so he knew exactly what to recommend. He recommended a window well drain that would catch any water inside the window well before it reaches the window and channel the water in the grate drain drainage system below that will channel the water to the Grate Sump .
