Midcoast residents can reduce heating costs by having interior storm window inserts built by WindowDressers, a volunteer-powered, local non-profit organization. Sign up at www.windowdressers.org soon to allow enough time to have custom-sized inserts made this year. Volunteers are currently measuring customers’ windows for inserts to be built October 16 to 26 and November 8 to 21. Pricing is based on size and finish (natural pine or painted white). A 30x52-inch insert in pine costs $28 plus tax and in white costs $37 plus tax. WindowDressers offers low-income households up to 10 pine inserts at no charge.
