Our recent experience with 303 Windows was exceptional! The team was a true pleasure to work with. Jay provided a thorough, fair, and quick proposal. After consideration, we decided to move forward with window replacements in only our kitchen instead of the entire home. When we relayed this to Jay, we never felt any pressure for the reduced scope and he quickly scheduled us. The installation team of Jake, Max, and Chuy was outstanding - they were engaging, professional, respectful of our home, and went far beyond our expectations. The finished picture windows are stunning! They are beautiful, high quality, and allow us to fully enjoy the beauty of our backyard. I cannot recommend this team enough!
Our experience with 303 Windows was excellent from start to finish. We needed to replace a very old and large front window, and the entire process was seamless.Our initial meeting with Jay was great. He was straightforward, honest in his assessment, and a pleasure to speak with. He provided us with an estimate on the same day, which made our decision easy when considering other vendors.As for the installation, we could not be happier with the professionalism and skill displayed by Jake and his crew. Our new front window looks absolutely beautiful, and we especially love the custom trim work they did.We plan on replacing other windows in our house, and there is no doubt that we will be working with 303 Windows for those future projects.
Outstanding Local Window Company – Exceptional Value and Quality Work!We couldn’t be happier with our experience. From start to finish, 303 windows delivered top-notch service, incredible value, and workmanship that truly exceeded our expectations. Our first meeting with Jay was so straight forward and efficient. He had the house measured in 30 minutes where other big name companies took as much as 3 hours. He got us a quote that same day.The team of Jake, Max, Chuy, Alan, Faris, and Marquise were extremely professional, punctual, and clearly skilled at what they do. By the end the whole group felt like family. The installation was smooth, efficient, and done with great attention to detail. Our new windows look fantastic and have already made a noticeable difference in the comfort and appearance of our home. On top of that, their pricing was extremely fair—especially considering the high quality of the products and the level of care they put into the job.If you’re looking for a local family owned company that combines great value, excellent craftsmanship, and an stress-free experience, look no further. Recommended with no reservations whatsoever.
We had nine windows replaced by 303 windows and the crew (Jake/Max/Chuy/Alan/Faris) was simply great. Communication was great from the start, everything and everyone was on time and the workmanship exceeded our expectations (especially as they had to address quite a few issues with the old frames). The guys, courteous and respectful, clearly enjoy their craft.We cannot say enough good things about our experience with 303 Windows and we highly recommend them for any size job.
Love our new windows! We had very old windows (original from 1888) that needed to be replaced. Really love the new windows. They brighten the space and make the room look larger. The guys were very professional and kind. Install was very easy. I am very particular and they made sure I was happy with the final product even doing some drywall work since I was wanting a minimal look (no trim). Really appreciate the customer service and attention to detail. Thank you! Posting before and afters…
