The Zen Windows Way – Our Step By Step Replacement Process

The process we use to sell and install windows in St. Peters is like none other. That’s because we’ve looked at things from your point of view as a homeowner, and work to make the process stress-free and easy for you.

Step 1: One Quick Phone Call
A five to ten minute phone call is all it takes. We’ll ask a few simple questions, download images of your house, and give you some information about our company. There’s no aggressive sales pitches or pressure tactics.

Step 2: One Business Day Later
Within just one business day, we’ll provide an exact quote for your new windows. The quote we email is the guaranteed price you will pay. Take as much time as you need to think things over; we won’t ever rush you by offering “one day only” prices.

Step 3: A Few Facts
We don’t want to bombard you with a ton of emails, prodding you into a purchase. But you will receive a few messages with information we believe is important to you as you make a decision. You will receive links to product demonstrations, as well as comments from our past customers. We try to give you the most basic facts, rather than a lot of marketing schemes.

Step 4: Scheduling and More
One important component of a stress-free window install in St. Peters is good communication. After we schedule your window installation, we will provide you with an emailed confirmation, which will explain what you can expect and how you can prepare for the big day. In addition, we’ll give you the name and contact information for the installation manager assigned to your project. That way, if you have any questions or concerns, you know just who to call.

Step 5: The Installation Day
How would you feel about a window installer who shows up and starts working without even a word of introduction? Sadly, that’s what some window contractors in St. Peters do. Not Zen! When your installation manager first arrives, he will introduce himself to you and answer any questions you may have before even touching a single tool. We make sure our installers have excellent communication skills, so you don’t have to worry about language barriers or confusing explanations.

Step 6: Feedback
If anything, no matter how small, is overlooked during your installation, we want to put it right as soon as possible. So, at any point during the process, you can feel free to contact no only the installation manager assigned to you, but also our company owners, Brian and Sara Zimmerman. Everyone at Zen Windows will work hard to make sure your experience is as pleasant and stress-free as possible.

Step 7: You Pay Nothing Until The Job Is Done
Many window installation contractors in St. Peters, Missouri, will require a deposit up front, but that is not how we operate. Your invoice will not be sent until the job is, not just done, but done right. There’s no prepayment or deposit required. And after paying for your windows, you can rest easy with our Lifetime Warranty, which covers most problems that you might run into, including glass breakage. To learn more about this guarantee, visit our Warranty Page.

In summary, the Zen Windows Way of doing things means stress-free, no-pressure service, with maximum accountability for our staff. If that sounds like a business you want to work with, give us a call to start your five-minute quote process.

Poor-quality windows might save you a few bucks up front, but you will pay for it every month with high energy bills. Investing in energy efficient windows in St. Peters helps keep your house insulated during hot summers and cold winters.

Energy Efficient Windows in St. Peters, Missouri

Many homeowners fail to understand just how much money leaks out their windows each month in the form of wasted energy, especially if the windows are over ten years old. And, of course, wasted energy means higher energy bills.




  • As time passes, energy costs continue to go up.
  • Thanks to global warming, heating and cooling needs are likely to increase.
  • Good windows save money by keeping your house warm in the winter and cool in the summer.

All Our Replacement Windows Are Energy Efficient

With replacement windows from Zen, you cannot make a wrong choice. We refuse to sell inferior windows to our customers, because we know that they cost more in the long run. Even our most affordable windows have a sophisticated, double-insulating Solar LowE glass system. This Solar LowE system incorporates double-strength glass, a high-performance Low-E coating, stainless steel Intercept™ spacer system and argon gas. And this superior blend of technologies is just our most basic option; from there, you can upgrade to even more efficient options. For example, we have an affordable triple glass configuration, several different Low-E coatings and spacer options.

While glass and coatings are the most important energy efficient factors, weather-stripping and foam insulation also play a part. All our windows come with superior wool-pile weather-stripping. Foam insulation comes standard on many of our windows, and is available as an option for others.

In short, no matter which of our St. Peters Replacement Windows you choose, you will be getting an energy efficient choice. We have ‘good, better, and best’ options, so you can find the best and most affordable windows.
