We recently completed this basement waterproofing project in the District to rid the homeowner of their water issues once and for all. After removing the old existing sump pump and pit, we installed a nice, bright CleanSpace vapor barrier, our WaterGuard perimeter system, and a new UltraSump. This will insure that they have a healthy, dry basement for years to come!

I just purchased a single family home in DC. The floors in the dining room and master bedroom are sloping. These two floors are part of an addition that was put on the house. I believe there was a porch, which they turned into a 2 story addition. I am not sure they built it correctly. I had a structural engineer come out and I am looking into options to add additional support under the dining room, in the crawl space. I would also like a quote for insulation of the crawl space.
