We talked with a handful of other companies in the area – both local & nationwide companies – and Zen was by far the best experience. Their approach of doing everything virtually without a salesperson is such a breath of fresh air in this industry. We replaced all of our windows, 13 in total, and are absolutely in love with the outcome. Our home is 100% masonry which makes for a more difficult install, but you wouldn't know it. Darrel and Eddie did an impeccable job and each one of the windows is stunning—inside and out. They even went above and beyond to help install some custom window sills I had ready for them when they arrived. Darrel did a great job patching our plaster walls that crumbled off when our 60+ year windows were removed. Both Eddie and Darrel were great to work with—friendly, professional, great with our two little boys that asked them endless questions, on and on... I could not recommend Zen enough!!

Great experience from start to finish. - Great Communication - Great Prices - Amazing, Honest Staff who truly care Cannot wait to get more windows replaced by them in the future!

After researching 6 companies and having 5 present with demonstrations in our home with high pressure sales pitches, we are so happy we continued our research and found Zen. After a few evening conversations with Dennis and receiving the quote, we decided Zen was the company for us! 6 weeks later- two friendly, trustworthy, experienced installers Eddie and Darrell started the job, replacing 19 windows in our two story home. The job was done perfectly, cleaning up after themselves and making sure all was done as expected. Geralyn Fisher2025-05-09Trustindex verifies that the original source of the review is Google. We are very happy with our Soft Lite windows purchased from and installed by Zen Windows. The windows are beautiful and substantial. Our house immediately felt more insulated; outside noise was noticeably eliminated. The crew from Zen were extremely professional. The main installer, Eddie, is a skilled craftsman who clearly took pride in his work. Zen offers an excellent life-time warranty, which is transferable, making our new windows an even better investment. We considered another window company, but decided on Zen because of the quality of their windows and the warranty. So happy we did.

Employees represented the company professionally and completed the work efficiently and timely. And I didn’t have to clean up a thing! Highly recommend. Nelu Nedelea2025-04-10Trustindex verifies that the original source of the review is Google. I had several window companies in my house before deciding to go with Zen Windows if STL. What I’ve discovered in the process is that a lot of these companies are dishonest, offer low quality products or ask for astronomical prices. I chose Zen Windows of STL and I am so impressed with them for the professionalism, transparency, product quality and price. The windows look much better than I imagined and they came faster than anticipated. I cannot recommend them enough. Looking forward to do the higher level of my house later this year. Donna Reckart2025-04-09Trustindex verifies that the original source of the review is Google. I had an excellent experience with Zen Windows from start to finish. Started with Rhonda. She was sweet, honest and very trustworthy. She was In no way pushy at all like other companies are when trying to get a quote. Rhonda is the reason, and the soul reason, I went with this company. Eddie and Darrell did the install and they were fabulous!! Their work was outstanding and they treated my home like their own. I was very sad when the job was completed, as I really enjoyed talking with these two upstanding men. Dennis addressed all my questions promptly, which is a huge plus for me. Kevin was just as amazing with the accurate measurements along with the minor touch ups that were needed after the install. I would highly recommend this company and crew to anyone. You will not be disappointed! Oscar Wright2025-03-29Trustindex verifies that the original source of the review is Google. Great windows, great install experience. They answered all of my questions along the way and the detailing on the window install is impeccable. The price was right too. I would highly recommend Zen Windows. Far and away the easiest to work with home improvement company I've encountered. Ron Glandon2025-03-29Trustindex verifies that the original source of the review is Google. I had an excellent experience with Zen Windows and highly recommend them. Dennis and Adam made the quoting process quick and easy, giving me the time and information I needed to pick the right windows for my home. Kevin was thorough and accurate with his measurements. Eddie and Darrell did an exceptional job with the install. They left my house in excellent condition and the windows look amazing. Throughout the entire process everyone at Zen Windows treated me with respect and displayed an outstanding level of professionalism. Easiest 5 star rating I've ever given. Chad Harris2025-03-26Trustindex verifies that the original source of the review is Google. Dennis and his team are the gold standard of customer service in a time when customer service is nearly nonexistent. We replaced all of the windows in our house with Zen Windows and it immediately improved the exterior look of our home, and of course dramatically improved the look of our interior. I can't say enough about this company and the quality level of communication we received.
