We had a very poor experience with another company when researching windows and installation and…read morewere a bit cynical of contacting another business. However, the process of obtaining a quote was indeed as easy as Zen Windows website makes it out to be; check out their website and watch the videos. I completed their form with the number of windows, approximate size and the requirement that the windows must meet a minimum efficiency. A reply was quick and thorough and above all easily understood and answers to questions were immediate. Dennis provided all the information needed should a permit have been required. Once accepted, Kevin came out within a few days to take specific measurements needed for ordering the windows. Within just over a month, we received a call asking if the installation could take place within 48 hours as they had an opening. Ed, Jimmy and Daryl were the installation crew who arrived promptly and you could not ask for a more conscientious and professional team. They seemed to get along and worked well with each other. Care was taken to protect floors and carpet, the installation and operation of the windows was explained, and clean up was meticulous. I had planned to shampoo my carpets after they were finished and Daryl did such a good job of cleaning up the floors I did not have to vacuum first! We had 6 windows replaced and opted for the Endure EN600 series double hung, Energy Star Certified windows. These windows were installed on a warm day in rooms that get the afternoon sun and it was immediately apparent that the sun gain was much lower than the previous windows. The wind is gusting today and there are no drafts! The total cost was a bit above some of the other estimates but after our previous experiences as well as the ease of the ordering process, the personable and professional installers- much less the quality of the windows- it has been well worth it.

Their seasoned installers were very professional, prompt, and respectful of our home. They worked hard to replace our entire two story home in one day before bad weather was supposed to hit the next day. We feel like we got a great product that will last for many decades which also has a great warranty. I would definitely recommend them to anyone wanting the best customer service and no pressure sales with a great buying experience.

Jesse explained in detail how the recommended windows would meet our needs and answered our questions. The windows arrived within the 3 month time period that was promised. Chaney has their own installers, they do not contract out. Hannah did a fabulous job with the installation over a 3 day period. She has 10 years experience and several of her family members are in the same business. We are completely satisfied with the new windows, and noticed the sound and temperature difference right away. Chaney was not the cheapest option, but it was worth it to get quality windows installed by true professionals.

We have repeatedly contacted the main customer service line, and they continue to tell us that the local St. Louis office will reach out. They never do. When we try calling the local office ourselves, no one answers or returns our messages. This has been going on for over two months. For the price we paid, the product quality and customer service are very disappointing. At this point, we are considering getting quotes from other vendors and returning the product altogether.

We had several quotes (few in the 6 digits). My husband and I just couldn't agree on which one to choose from. The quotes were either too high or did not on design, and sometimes both. I called STL Design and Build Design, setup an appointment as my last resort. STL Design sent Tom Levinson. Mr. Levinson arrived earlier than time with his assistant. This is definitely a rare. We went through the areas for remodeling. Tom sat me down and listen to all I wanted to do. Then it came down to the details and pricing. The wants an can't live without. We finished with an estimated quote that we were very happy with. Tom was wonderful. He gave me sound advice on my selections for the kitchen remodel. He went through the cost, time-line, and process. Tom went to warehouses with me for selections on the items. Matthew Pevehouse, thank goodness for him. I had a family emergency out-of-state. Matt took care of everything for us. The whole crew were wonderful. Matt took pictures and kept me up to date. If there was an issue it was quickly resolved. My husband and I are thrilled with the results. The look is absolutely fabulous, the craftsmanship and quality of products excellent, and done on time. Thank You STL for a wonderful experience.
