Egress windows in Chatham

Chatham sits at the elbow of the Cape, surrounded by water on three sides, with shingled capes and summer cottages from its fishing-village past.

An egress window is usually what makes a basement bedroom legal. Chatham is extending town sewer neighborhood by neighborhood, and homes not yet connected are on septic. On septic, the new bedroom also needs the Chatham Board of Health to confirm the system can carry it under Title 5, so we check that before we cut the foundation.

Near the sound, Pleasant Bay, and the ocean, 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.

On a historic building, we check with Chatham’s Historical Commission before changing the foundation or the exterior.

In Chatham, our work includes the restoration of a 1904 cottage overlooking Chatham Light, which received a 2022 Chatham Preservation Award, and a modern coastal estate with a Nano Wall glass system and two custom staircases.

Questions

Basement Egress Windows in Chatham: FAQ

Do I need a permit for an egress window in Chatham?

Yes. Cutting a foundation wall is structural work, so the Chatham Building Department issues a building permit and inspects the opening. We handle it.

Do you install egress windows in Chatham Village and North Chatham?

Yes. We install basement egress windows all over Chatham, including Chatham Village, North Chatham, South Chatham, West Chatham, and Chathamport. Our base in South Yarmouth is about 13 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 Chatham need anything else?

Enough ceiling height, and septic or sewer capacity for the extra bedroom. Chatham is extending town sewer neighborhood by neighborhood, and homes not yet connected are on septic.
