The business is hit and miss depending on the installation crew . They try to get the job done as quickly as possible and the quality of work suffers. If you are lucky enough to get the right installer the job is done to perfection .

Capstone Windows in Tucson was an amazing company to work with from beginning to end. Charley kept in contact from the moment I placed the order throughout the installation and asked for feedback about how the job went at the end. This company cares about their work. Their initial consultation was pleasingly different from the high pressure sales of other companies I checked out which made the choice easy for me to go with them. Now, I've got brand new windows and a sliding door that I couldn't be more happy with! Ryan and Richard who installed them were wonderful! Respectful of my home, polite, friendly, knowledgeable and completed the job with superb craftsmanship. Totally satisfied and happy with the install and would not hesitate to recommend. Thank you Capstone Windows-Tucson!

Had 5 windows replaced in our house to the tune of $10K. I have no problem paying for a quality product however I don't believe that the "Infinity by Marvin" windows are living up to what was touted during our sales consultation. A few months in when the weather cooled off and we were able to start opening and closing the windows the problems began. The windows started coming off their tracks when we would try and close them. Had an installer come out to see what the issue was. Turns out, these overpriced-cheaply constructed windows have a rather cheesy weather seal that is the only thing holding the window in it's track. Installer told me he wasn't "a fan" of this type of window and that a 5 year old could easily push on it and knock it off it's track. I'll be reaching out to the owner and probably the BBB. Totally disappointed, disgusted and $10K in the hole.

I had several windows and one sliding door installed by this company in 2017. They said there was a lifetime warranty on the product but I never received any Warranty information nor any contact information for the manufacturer. In 2020 I made several attempts to contact them to get the warranty information. No response to my emails or voice mails. I now have a problem with the screen on the sliding door. Over the past month, I have left voicemails , emails, messages on their website, with no response whatsoever. Based on their complete lack of response, I would recommend avoiding this company.

The screen for one of our eindows will not open. The track appears to have moved so the screen cannot slide in it. Tried calling the company multiple times, but they will not answer, and will not call back when we leave a message.

John did a terrific job replacing 8 of our windows. His team was on time, and communicated very clearly with us throughout the process. I highly recommend Small Improvements!
