Super unprofessional company. They do not stand by the product they sell and the follow up is very bad. There are a lot of window and door companies that are much better than this company. RUN RUN do not buy from them.

Amazing. Fantastic. Professional. Attention to detail. Clean clean work. And the best prices Hands Down for Retrofit and New Windows installs. We had Home Depot, Anderson and one other company quote the windows. Their quotes came in for 8 windows between $9000 - $12000. Their install prices were between $400-$1000 per window. Windstar came in below $4000 for Milgard Tuscany installed and their install price per window was half the lowest quote. I hired Windstar on behalf of my 83 year mother to install 8 windows. I stumbled in off the street and Kevin, the owner had time to give me a quote. We talked quite a bit and it was obvious his knowledge of the business is beyond extensive. He didnt try to upset me. He explained to me the difference in vinyl windows and why you should upgrade to a better line of Milgard - Tuscany. He also explained why he always recommends thicker glasss - quieter, less broke to break when a lawn mower throws up something at the window and breaks it. Windstar has been business for over 30 years. They have seen at least 3 housing busts and they survived. That says a lot. He also told me they cover everything and vacuum are are super super clean. My mom is a neat freak and this is beyond important to her. We finally ordered the windows and they came to install them. The crew, Enrique, Enrique and Pedro showed up on time, they covered everything and started. The crew was so kind and polite to my mother. They are SUPER. They are also work very, very quickly. I noticed Enrique was trimming the flanges of the retrofit windows. I asked him why. He said Kevin, taught him this is how real professionals install retrofit windows. Otherwise the flange either doesnt seal well to the stucco and over time you have leaks or the flange gets pushed out and in over wood as the wood swells and you have leaks. I have never seen his done. When I did my house, no one did this and sure enough after 15 years, the caulk seal gapped opened and I had a a small leak that damaged my sheetrock on one window. On the install, I also noticed they used gap filler by Hilti. Hilti is a very, very high end equipment and caulk maker from I think Switzerland. At that moment I knew Windstar only used the best of the best stuff. The rest of the install went perfectly and they cleaned up and vacuumed and did an Amazing job. A day later my mom noticed the bathroom windows were really hard to open. She called Kevin and he sent someone down. The windows were slightly to thick to move easily. They readied the situation and my mom is now so so happy. If you want the best and a reasonable price, their is no one better than Windstar. The office staff ar superb too. Anna is exceptional. I think the employees stay with Kevin for a long time because I can tell he not only runs a quality business, but he also treats his employees really, really well. Please support quality businesses like Windstar. They are AMAZING!!!
