Guida Door & Window installed windows for me and they were just awesome. They were very courteous and thorough. I asked questions and they had answers. I'm a person who observes closely, and I noted that in each phase, they made sure that everything was perfect before they moved on to the next one. They always cleaned up after their work, and never left a mess. They were just very nice. It was a really great experience. Everything turned out perfect; I was happy enough with their work that I have already recommended them to three other people!
