Remodeling a basement in Provincetown
Provincetown sits at the very tip of the Cape, with historic houses close together on small lots between the harbor and the dunes.
Near the harbor and the dunes, groundwater can sit close to the surface, and many older basements in Provincetown were finished without any moisture control behind the walls. A remodel here starts by opening those walls and fixing what caused the dampness, and if the house is in a FEMA flood zone, by checking how much of the space below the base flood elevation can be finished.
Much of Provincetown’s center is on town sewer, while homes outside it use septic. That matters if the new layout adds a bedroom, because Title 5 ties septic capacity to the bedroom count.
In a Provincetown summer home, a remodeled lower level often becomes the space for guests. Schedule it for fall and winter and it is done before the season.

“Mussato Building Group has been a loyal and trusted partner of ours for over ten years and one hundred projects. Their professionalism and quality of work are second to none. We look forward to working with them far into the future.”

Basement Remodeling in Provincetown: FAQ
Do I need a permit to remodel a basement in Provincetown?
Yes, if the remodel changes walls, wiring, or plumbing. The Provincetown Building Department issues the building permit, and licensed electricians and plumbers pull their own. We coordinate all of it.
Do you remodel basements in the West End and the East End?
Yes. We remodel finished basements all over Provincetown, including the West End, the East End, and the Commercial Street area. Our base in South Yarmouth is about 42 miles away.
Can you add a bedroom in a remodeled basement?
If it gets a code-compliant egress window, enough ceiling height, and septic or sewer capacity for the extra bedroom. Much of Provincetown’s center is on town sewer, while homes outside it use septic.
What do you do with the old paneling and carpet?
We take them out and haul them away. Carpet laid on concrete and paneling over bare foundation walls are usually where the moisture and the smell were hiding.
