Maine-based nonprofit WindowDressers coordinates community volunteers to build affordable, re-usable, interior insulating window inserts that tighten up existing windows. The cost of the insert depends on the size of the window, but averages $25 for a medium-sized insert in natural pine. Twenty-two percent of the inserts built are reserved for low-income customers for a small donation. Go to or call 596-3073 to sign up.

Volunteers are needed now through December at the Lincoln Street Center, 24 Lincoln St., where lumber for the inserts is cut, drilled, and assembled before being sent out to the 27 Community Builds across the state. At the Community Builds, customers and volunteers come together in an organized, barn-raising model to construct the custom-built inserts for themselves and their neighbors.

The production center at Lincoln St is open from 8:30 a.m. to 4:30 p.m. Monday through Friday, and volunteers can sign up online for morning or afternooon volunteer shifts at, or call 226-3555 to speak with a volunteer coordinator. Volunteers of all skill levels are welcome and will be trained on site.
