Waterproofing a basement in New Seabury
New Seabury is a resort community on Nantucket Sound in Mashpee, made up of separate villages such as Maushop Village, The Mews, Bright Coves, Fells Pond, and Triton Sound.
Near the sound and Popponesset Bay and in low areas, groundwater can rise after heavy rain. In New Seabury, we start with the outside, gutters and grading, and add an interior drain and a sump pump only where the water keeps coming in.
Some New Seabury neighborhoods are served by their own wastewater treatment plants rather than individual septic systems, so before a sump pump goes in, we confirm how your lot is served and where the discharge can go. Lots near Nantucket Sound and Popponesset Bay are often in flood zones, where groundwater rises after storms.

“As the General Manager of Pretty Picky Properties I’ve had the pleasure of working with Joe and his team for nearly 10 years. Joe’s carpentry skills are unmatched. He’s always respectful, finishes on time, priced well, and transparent from start to finish. You will not regret hiring Mussato Building Group.”
