Energy-efficient windows are more than just a nice-to-have; they’re a smart investment, especially in Colorado’s unpredictable climate.

This isn’t just about comfort; it’s about long-term savings and making smart upgrades that pay you back.
Options for Every Home Without the Upsell
Unlike some companies that steer you toward the priciest window in their catalog, we guide you toward the right fit, both literally and financially. Whether you need double or triple-glazed glass or want to explore different frame finishes, we offer the options and let you decide.


The Zen Windows Installation Experience
How It Works: From Quote to Installation
We keep things simple: you reach out and tell us what you need. We’ll provide a quote, often within a day. Once you approve it, we’ll collect measurements, order your custom windows, and schedule window installation at your convenience. It’s a streamlined process that puts you in control.
Professional Installation
Our window installers are experienced professionals. They’ve installed windows in dozens of Colorado homes and understand how to get the job done right the first time. They’re polite, punctual, and leave no mess behind. We always make sure you’re happy with the final result before calling the job complete.
Our Double Limited Lifetime Warranty
We stand behind our work and our products. Every installation comes with our Double Limited Lifetime Warranty, which covers both materials and labor for as long as you own your home and then some. It’s a level of protection you won’t find with just any window company.

Zen Windows was very helpful and professional and went out of their way to help me find a window trim color that I was looking for. I called a couple of other places and left messages but did not hear back. I very much appreciate their prompt attention to my question.
