Windows & Energy Efficiency

Mary Ann writes about the small window problems that slowly turn into big ones. Drafts in the winter. Fogged glass. Rooms that never seem to stay the right temperature. After helping homeowners troubleshoot these issues for years, she focuses on explaining what’s happening and when a repair makes sense versus replacing the window. facebook.com/mary.ann.builds
