Button Up Your House For Fall

Seal gaps larger than 1/8 inch around windows and doors to cut your winter heating bill by up to 15 percent. On windows, press adhesive-backed closed-cell foam onto the bottom of the sash. Secure a loose sash by applying a strip of plastic V-channel weather­stripping in the groove the sash slides in, securing it with finish nails. Use foam strips on the sides and tops of doors, and install a door sweep on the bottom.
