New Windows and Doors

Average cost: $7,082

Homeowners can recoup 68 percent of the cost of replacing windows, while a new fiberglass entry door recoups 56 percent and a steel entry door 73 percent. Most exterior doors should last as long as the house does, though vinyl doors have a life expectancy of 20 years. Aluminum windows have a life span of 15 to 20 years, while wooden windows should last more than 30 years.
