Ask Build: Replacement Windows

A new feature on our blog will be answers to commonly asked questions from clients. Here is one in reference to the costs of window replacement in relation to energy savings.

Q. We are considering replacing our windows in our home to save on heating and cooling costs. Are new windows a good investment in terms of energy efficiency?

A: New windows are not necessarily a good way to save energy. Many good wood windows are replaced with poor quality (especially vinyl) windows that do not improve the efficiency and do not compliment the house architecturally. 


If you have nicely detailed wood windows that are original to the house, you can repair them and fit wood or aluminum storms. New windows are expensive to supply and install properly, and may have a 20 to 30 year payback! You’re better to spend your upgrade dollars on improving the insulation in your attic and basement and sealing air leaks around your home. Rory
