We found this video, presented by Brian Gunderson of Anderson Windows, to be highly informative for helping you determine whether or not your windows need to be replaced. According to Gunderson, the average age of windows being replaced these days is just seven years. Key things to look for include: drafts, difficultly opening or closing them, and foggy glass. New windows can also drastically improve your energy efficiency.
