After many years of struggling with old aluminum storm windows, my Harvey windows were installed in 2008. These windows are the best gift I ever gave myself - a significant reduction in heating costs, and so easy to clean. Recently I contacted Harvey Customer Service about one sash that developed a slight haze. They immediately verified the warranty and specifications and ordered a replacement sash. I am so pleased with the quality of the windows and the service that I am considering replacing a patio door with a Harvey door set.
