Job Stories From Sultan, WA
Sump Pump Services Sultan, WA

Lexie in Sultan, WA, called Rainy Day about water leaking into their basement. Water was finding its way through cracks in the foundation and streaming in. They had a water restoration company out already, and were now looking for a permanent fix. We sent our Design Specialist, Ryan, out for a free inspection and estimate. The system we designed included installing a drain along the perimeter, drywall removal and restoration, and the installation of a new sump pump to help keep the space dry for good. 

Cleaning Out and Sealing Off Moldy, Rodent Infested Crawl Space in Sultan, WA

Sherman was having problems with his crawl space in Sultan, WA. He had rodents tunneling under his foundation, fallen insulation, and mold. It was a general mess under his home. We came and cleaned the crawl space and disposed of the loose materials underneath it. We then sealed the crawl space using our CleanSpace encapsulation system, a vapor barrier that prevents moisture, mold, and pest intrusion. A SmartDrain was also added just in case there are plumbing leaks in the future to prevent water from accumulating above the CleanSpace. We also maintained the humidity in the closed space automatically by implementing a SaniDry Sedona humidification system. The result was a dry, closed crawl space that is protected for years to come. Sherman no longer has a need for the fiberglass insulation, and the home is now more clean, energy-efficient and comfortable than ever before.

1 block away they started remodeling a 100 year old school building that has been abandoned. Rodents moved in. We solved the rodent problem with an exterminator but my crawl space needs to be cleaned. It was really clean prior to the rats, but the exterminator said it has a lot of rat droppings and some torn insulation.
