In todays market, buyers statistically shop for homes with energy efficiency in mind. Especially in California. Drafty out dated single-pane windows negatively impact your homes selling power. Adding more energy efficient windows such as Larson's Comfort Seal Technology can literally save you up to $500 a year on your utility bills. Not only are they keeping out sound they are also less drafty and keep out dust, dirt and hot or cold air.

You can potentially expect to recoup 60%-90% of your costs on a reduced power bill. Additionally, you qualify for a green energy tax credit of 10%. "Energy Star estimates that the average cost of window replacement in an average-sized home costs $7,500-$10,000, or more. If the new windows save you several hundred dollars a year, and you recoup a tax credit, you can eventually recoup your investment."
