INSTALL INSULATION
To save big on the electric bill and boost your home’s resale value, stop warm air from escaping through the attic during the colder months. It costs about $1,343 to hire a contractor to air-seal the average-sized attic floor and pump in fiberglass loose-fill insulation. In addition to immediate savings, expect to make a 107.7 percent return on the improvement when the house is sold.
