Job Stories From Bristow, VA
SaniDry Sedona Protects Bristow, VA Basement from Mold Problem

By the time a Bristow, VA homeowner noticed water leaking in through a crack along with one of their basement walls, the moisture had already begun to have negative effects. Signs of early mold development were showing and the homeowner needed a solution, fast! When they heard about 3 Pros Basement Systems from a neighbor, they called us right away to set up their free estimate. Shortly after, they spoke with our sales professional and decided on the work they wanted done to protect their home. The installation crew arrived at the home and got started solving the problem of the crack in one of the concrete basement walls. Utilizing a FlexiSpan seal to keep water from entering through this wall, our crew quickly applied the three-part seal along the length of the crack. The FlexiSpan structure has a foam core between two layers of sealant, which allows the seal to bend and contort to stay in place over the crack should it ever shift slightly in shape in the future. Next, to eliminate the developing mold problem entirely, a SaniDry Sedona dehumidifier was installed on the basement floor. This device pulls in the surrounding damp air and separates moisture from it. The dried air is then circulated back into the basement where it cycles more damp air back to the SaniDry, continuing the process. Once the atmosphere within the basement is free of moisture, any mold attempting to grow no longer can sustain itself. The moisture collected through the SaniDry is pumped from the home through a PVC discharge line. Now this homeowner doesn't worry about their basement during rainy weather. The SaniDry Sedona will ensure the space remains moisture and mold-free for years to come. 

A Properly Conditioned Crawl Space

This customer had pipes in their crawl space that required the surrounding air to be "conditioned" - keeping the pipes properly warmed in the winter and cooled in the summer. 

Many of our competitors are able to air seal or "encapsulate" crawl spaces, but few take the extra time to fully condition them by insulating the walls and floors. The 3 Pros team got the job done for this customer and properly conditioned their crawl space using a Spray Foam insulation  and Terra Block Floor insulation.
