Premier One Improvements, Inc provided me with very good service and they did an outstanding job! They replaced the front door with a lead-lined glass door. I've seen them originally at the Orange County swapmeet, and afterward, I learned that one of my neighbors used them. I loved what they did with his doors, so I called them up and spoke to David. He came back and I told him exactly what I wanted. The installers were excellent. They were very clean, friendly, and they did a great job. I've since recommended them to my sister-in-law, and I don't do that much, as I don't recommend anyone I don't trust. If I ever need another door or a window replacement, I will call them again!
