Another 5-star review for Arizona's Best Windows! Robert and Lori were super awesome, fun to have in my home, and did spectacular work. His quote was thorough and was exactly what I paid.
I had five 1964 single-pane aluminum-frame windows replaced with his manufacturer's double-pane high quality windows (3 small windows, 1 medium window, and 1 large picture window). He told me he researched for a few years before deciding on the best window manufacturer he could find. They may be a bit pricier, but they have a lifetime warranty. They also look great!
I also had my old gross french doors replaced with a huge sliding glass door.
Grand total was $4700-ish.
I couldn't recommend this company more.
