Basement Waterproofing in Groton, CT

Groton, the Submarine Capital, sits across the Thames from New London on the Sound. Between the shoreline neighborhoods and the homes near Electric Boat, a lot of Groton's basements sit close to a high water table, with older homes near the water and newer ones inland.

DryNest waterproofs Groton basements from the shore to the inland subdivisions. We build drainage that handles the high water and keeps the basement dry and usable.
