Finishing a basement in Bourne
Bourne is the only Cape town on both sides of the Cape Cod Canal, from Buzzards Bay and Sagamore on the mainland side to Pocasset, Cataumet, and Monument Beach on the Cape side.
Finishing the basement adds living space without adding to the footprint of the house. In Bourne, it is often simpler and faster to permit than an addition.
Near Buzzards Bay and the canal, groundwater can sit close to the surface, so every Bourne basement starts with a moisture check. If the house is in a FEMA flood zone, we also confirm how much of the space below the base flood elevation can be finished.

“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 Finishing in Bourne: FAQ
Do I need a permit to finish a basement in Bourne?
Yes. The Bourne Building Department issues the building permit, and licensed electricians and plumbers pull their own permits for their work. If the plan adds a bedroom, the Bourne Board of Health reviews septic capacity under Title 5.
Do you finish basements in Buzzards Bay and Sagamore?
Yes. We finish and remodel basements all over Bourne, including Buzzards Bay, Sagamore, Sagamore Beach, Bournedale, Pocasset, Cataumet, and Monument Beach. Our base in South Yarmouth is about 28 miles away.
Can a basement in Bourne have a bedroom?
It can if it has a code-compliant egress window or door, enough ceiling height, and septic or sewer capacity for the extra bedroom. Buzzards Bay village has town sewer, and most of the rest of Bourne is on septic. On septic, the Bourne Board of Health has to approve the extra bedroom under Title 5 before we build it.
Is my basement too damp to finish?
Not necessarily. Close to Buzzards Bay and the canal, groundwater can be near the surface, so we look for water stains, white mineral deposits on the walls, and high humidity first. If there is a problem, it gets fixed before we frame.
