Our Window Installation Process

What sets us apart from other window replacement companies in St. Louis is our process, prices, exceptional service, and consistently excellent results. If you’ve ever bought windows from any of the “big brands,” you’re probably familiar with their VERY high-pressure salespeople. At Zen Windows, we never use high-pressure, in-your-face tactics. Instead, we take the stress out of getting window quotes by letting you submit your information online or over the phone. Here’s how it works from start to finish…

Thousands of Windows Installed, Hundreds of Happy Clients

Before hiring just any St. Louis window replacement company, be sure to check their reviews. Hundreds, if not thousands, of people every year are pressured by the “big brands” into buying windows they don’t want, don’t need, or can’t afford. Don’t let that be you.

At Zen Windows St. Louis, we have dozens of reviews, and not one of them is negative. Go ahead and read about what it’s like to work with us compared to other companies. Get it straight from the customers and NOT from a pushy salesperson. Do your research, we encourage you to. We’re confident you’ll make the right choice!

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.
