Lifetime windows and doors is the right choice! We had a sliding patio door replaced with Lifetime. Diablo was our installers name and he did a fantastic job. He covered all areas to avoid dust and debris in the house as well as outside the house. He worked nonstop until the work was done. He was courteous, respectful and kind answering all our questions. I would definitely recommend Lifetime as well as Diablo to get the job done right! Thank you!
