I researched a few window companies and received some prices quotes. Arizona's Best Windows offered a great price for a great brand (Simonton) of window. I liked that Robert, the owner, allowed me to send him some rough measurements over email so I could at least get an idea of what cost I'd be looking at, others insist on coming to the house to give you their hard sell. When I accepted his bid, Robert came and obtained more precise measurements. He told me when the windows would arrive, and he was prompt and reliable on installation day. Another plus, he put the ADT security sensors back on the new windows.I don't think they usually do that, but that really saved me some time by not having to deal with ADT and the cost associated with them coming out to the house. The window installation went well and I'm extremely happy with the windows and the install. Wish I would have done this sooner.
