The owner came on site to supervise the installation. The door arrived damaged from the factory but was quickly replaced with a perfect one. The installation is beautiful, and a problem around the old door was repaired at no extra cost. The installer was excellent and detailed.

Went very well. Excellent communication, punctual and friendly staff. They used cloths to cover all my carpet and cleaned up all their mess. Left my house cleaner than it was when they arrived. Wow! Will use again or refer to others.

What a great way to buy windows! I was able to get a quote and buy windows over the phone without having a salesman come to my house. I would definitely recommend Zen Windows St. Louis and will be using them again.
