    November 10, 2016
    Steve proposed a full perimeter Grate drain drainage system that offers a lifetime warranty and is transferable to the next homeowners. This was key with her putting her house on the market soon. An air-tight Grate Sump pump was installed to replace their open Sump pit hole to go along with a crawlspace encapsulation system with structural repair to turn the crawlspace into dry usable space. By doing so, Mrs Opalisky turned 2000 sq feet into Dry usable space, therefore uping the value of her home.
