Egress windows 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.
An egress window is usually what makes a basement bedroom legal. Buzzards Bay village has town sewer, and most of the rest of Bourne is on septic. On septic, the new bedroom also needs the Bourne Board of Health to confirm the system can carry it under Title 5, so we check that before we cut the foundation.
Near Buzzards Bay and the canal, groundwater and heavy rain are the main risks for a new window well. We build the drainage at the bottom of the well and grade the soil around it so water moves away from the opening.

“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.”
Egress window permits in Bourne
We prepare the drawings, file the applications, and schedule the inspections. Here is what a project like this usually needs:
- Building permit from the Bourne Building Department for the foundation cut and the new opening.
- Review by the Bourne Board of Health under Title 5 if the window is for a new bedroom on a septic system.
- Flood-zone review if the house sits in a FEMA flood zone.
- Code check of the opening, sill height, and well
- Foundation cut for the new opening
- Egress window set, flashed, and sealed
- Window well with ladder or steps where needed
- Drainage at the bottom of the well
- Interior framing, insulation, and trim around the window
- Replacement of small basement windows
- Building permit and inspection
Basement Egress Windows in Bourne: FAQ
Do I need a permit for an egress window in Bourne?
Yes. Cutting a foundation wall is structural work, so the Bourne Building Department issues a building permit and inspects the opening. We handle it.

Yes. We install basement egress windows 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.
What size does the egress window need to be?
At least 5.7 square feet of clear opening, at least 24 inches of clear height and 20 inches of clear width, with the sill no more than 44 inches above the floor.
Does a basement bedroom in Bourne need anything else?
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.
