The ONLY reason I went with this company was the quality and strength of the windows themselves. The installation and workers were atrocious. When I was getting estimates I got them from a few companies. Hanson was the only one to insult and degrade their competition. They touted themselves as the best and everyone else was "crap" by their definition. Though they supposedly measured, only one of the windows they brought to install actually fit the frames. Their workmanship leaves everything to be desired, and they even just put my old trim back up, they did not install new trim as planned. I would NEVER use this company ever again.
