5-Star Review: Excellent Experience at Window Expo!
I was thoroughly impressed by the quality products and exceptional service at the Window Expo.
A huge thank you to Alyse, who made the experience seamless. Alyse possesses incredible product knowledge, patiently guided me through my options, and offered suggestions that were genuinely helpful. Her professionalism and positive attitude made the consultation a pleasure.
I highly recommend visiting the Window Expo and specifically asking for Alyse!
Very happy overall with work done. My wife had a vision on what she wanted her new master bath to look like and the team at K-Designers took that dream and made it a reality! High quality products. Great communication. As with any construction project you run into unforeseen issues, this team was open, honest and communicative with options. That made a world of difference! Overall happy and satisfied!
Professional and knowledgeable of the products. I t was a joy to have her in my home
Pleasant representative
This was our first experience replacing windows in our home. We shopped around and priced windows for months before finding universal windows. Starting from the first phone call to schedule an appointment with the sales person to the day the installer left, our experience was positive. The windows are everything we wanted and more! The installer was incredibly professional and respectful of our property. We have already told our neighbors and friends about our experience and would suggest universal windows direct of St. Louis to anyone.
Very polite salesman and very knowledgeable. Damien looked for ways to save us money for the Christmas holiday and get us the product we wanted. Found us financing options with different rates and terms for the loan. Left the options to us with the concern of getting the best rate. This is the kind of sales that leave you feeling good once the paper work is done. Thank you Damien looking forward to seeing you at our next home upgrade with vinyl siding.
It’s definitely worth the home visit to have a better understanding and visual of what the end result will be. The rep, Jason, was thorough and provided the details we needed to make our decision to finalize the sunroom.
Universal windows sent Alexander out to our home to give us an estimate for replacement windows. Alexander was very personable and professional. He was knowledgeable and explained everything we needed to know. I’m sure we will be satisfied with our new windows!
Jeff was very thorough and knowledgeable, and gave me a very interesting presentation. I appreciate it very much.
Joel, is an amazing person. Excellent service. He has given me a very reasonable price. You are appreciated!
