Shellie S. ★★★★★
"Installers were on time and very fast, friendly and did a great job cleaning up. Brad was helpful in showing me how to use my new windows. I am excited to see the difference in these windows from my old drafty windows."
Cindy C. ★★★★★
"I spent a lot of time shopping for new windows for my home, and after reviewing all the options, I settled on Ameritech for a combination of quality and value. No other company could match what Ameritech was able to provide. Further, it was a pleasure working with Scott and the rest of the team."
Dan D. ★★★★★
"Scott with Ameritech was great with showing us all options and what the pros and cons of each option. His visit was very informative and we came to an excellent decision for our doors. Also there 40 year warranty is amazing. We will be looking at Ameritech again for future upgrades!"

The Quick Guide To The Best Replacement Window Experience In Colorado

Here’s what homeowners LOVE about our windows:

Most window companies in Denver and surrounding areas will tell you that double-pane windows are good enough. Or they will even try to say that their windows are “just as good” because of extra coatings of Low-E or other add-ons. But that’s simply not true. NO amount of manipulation of a single or double pane window will make it as good as a triple pane window. Triple-pane windows are much more energy-efficient, more secure, and significantly reduce noise inside your home.
Many windows being sold in Colorado are hollow vinyl frames (or foam-filled frames that might as well be hollow). Our windows are rock-solid with High Density Resin to reinforce our frames for super strength.
Our windows are beautifully designed. For example, the locks are elegantly integrated into the frame. (Compare this to most windows where the lock is just stuck on top of the sash, cheapening the look of the window). Our frames look vibrant and attractive and are virtually maintenance-free.
Our windows are more secure, with the extra protection of hard-to-penetrate triple-pane glass and super-strong frames. And our locks are better than typical window locks. Most locks are screwed into a hollow vinyl frame and a crowbar can remove them in about a second. Our locks are solidly anchored into the High-Density Resin inside our frames. Also, since our locks are not easily visible from outside, burglars can’t even identify where to get to them.
Most so-called “Lifetime, Limited Lifetime, Double Lifetime” warranties are vague. Not only do most of these warranties have many loopholes and exclusions, there is also often confusion on how “lifetime” is defined. Ameritech’s window warranty is different. It’s real, well-defined, and far superior to typical window warranties.
This is your home. Get the secure feeling that comes with doing business with a company that’s been around more than a quarter century, has an A+ rating with the BBB, and has 700+ Google Reviews.

If you are interested in more information about our windows and what makes them special, please visit our Windows page. Of course, the best way to understand the amazing quality of our windows is to see them for yourself. We’ll bring them to your home for a free consultation and quote – schedule an appointment now!
