It was time to replace our front door, patio door and three windows in our house. The original owners had replaced the front facing windows just prior to us purchasing, so they did not need to be replaced. A friend of ours had used Casa Bella the prior year and invited us over to view their windows. They were nice, but to me a window is a window. It is in the install that there is a difference. We received two other quotes, and both those sales men focused on the window product itself. Al Smith, the salesman from Casa Bella, did explain the windows and doors in detail, but also focused on the install itself. I did a bit of research online myself, and my assumptions were right. Most windows from reputable companies are made well and are energy efficient, but if the install is terrible, then you run the risk of water entering the home, wind leakage, etc... and that totaly defeats the quality of the window. The install crew that arrived from Casa Bella were one of the best I have ever had. They were professional, curtious, personable and hard working. German (forgive me if that is not the correct spelling of your name) and the other two (there names escape me at the moment) did a beautiful job. They communicated intentions if there was a choice during the install, and explained the complete install at the end. German had great difficulty installing our new lock set, he spent over an hour trying to make it work. In the end it turned out to be a defective lockset, and after having it exchanged, he installed it in minutes. My appreciation for him trying to make the first one work, and letting me know that there was an issue. I am very satisfied with the complete process, and wish other companies I interacted with where as good as them. Bottom line, very pleased we chose them.
