(BPT) - With spring quickly approaching, it’s a good time to begin thinking of home improvement projects that will look great, but also save energy. Window replacement is one project that will help increase the energy efficiency of your home and improve curb appeal.

There are often telltale signs a home may be in need of new windows, including air leakage, difficulty operating, condensation between glass panes, or exterior paint peeling. Homeowners can check for signs of disrepair by visiting each window and testing operation, checking for air leaks and water collection.

For homeowners planning to update their home with energy efficient windows, Ply Gem Windows offers five important questions to ask their contractor before beginning a project. “Today’s window options go beyond color and style. When meeting with a contractor, homeowners should plan key questions to ask,” says Chris Pickering, vice president of marketing for Ply Gem Windows. “Installation methods, energy efficiency and issues such as lead paint should be discussed with a contractor to make the most out of your investment for seasons to come.”
