I recently had a bathroom window installed by A-1. I cannot say enough about both Diana, the sales rep, and the installers who I had the pleasure of meeting. Professionalism from start to finish. Diana worked with me for hours finding the best fit for a difficult situation. I had beautiful tile that needed to be cut through very carefully, along with siding on the outside of the home. I was nervous to say the least, but the outcome was just beautiful. The installers were total gentleman, making sure all my rugs were covered, and as polite as could be. My brother could not get over what a beautiful job they did, (he installed windows and doors many years ago). I would recommend Pella highly.
