#1 Window Company for Colorado Front Range

☆☆☆☆☆ 5/5

“These windows were so well insulated and also cut down so much on outside noise that we knew we wanted them for the net-zero energy home,”

"I have used Ameritech twice for window replacement. Each time, I have been impressed with the professionalism and quality of the windows and doors. The whole team is friendly and great at their jobs. My house looks great!"

"We had our basement windows replaced last year and are now replacing the upstairs. Amazing company to work with and window quality is top-notch. Questions are answered timely and the customer service is on point. Made for a very good experience. Thank you!"

"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."

"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."

"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!"

Thornton’s Absolute Best Replacement Windows

Windows Installed By A Top-Rated Company
In Business Locally For 25+ Years

For the absolute best replacement windows in Thornton, Ameritech Windows is the proven choice.

When we say we have the very best windows, that’s not just talk – we’re 100% serious. Compare our windows to anything else available in Colorado – no other window can match the amazing quality of our window.

Triple-Pane glass is the best choice for your home

The superiority of our windows starts with our triple-pane glass. Most Thornton replacement window companies recommend double-pane windows. Those aren’t good enough, even if you do add-ons like extra coatings of Low E. Nothing you can do to a double-hung window will make it match the quality of triple-pane!

Ameritech’s triple pane glass will keep you home much more comfortable in the blazing heat or deep cold. Triple-pane glass also reduces outside noise from penetrating inside your home and makes your home more secure.

Everything about these windows is of the highest quality

Our replacement windows for Thornton homes:

Have terrifically strong frames because they are all reinforced by High Density Resin. Compare this to the hollow or foam-filled vinyl frames that most companies install.
Increase the curb appeal of your home, with elegant features including locks that are integrated beautifully into the window frame.
Are virtually maintenance free – an occasional cleaning is all you have to do to keep them looking awesome.

A warranty with teeth

Most window warranties have too many loopholes and exclusions. We’ve even seen some warranties from other Thornton window companies that exclude coverage for “normal weathering.” If that’s not covered, what is?

Window warranties are often referred to with names like ‘Lifetime,’ ‘Limited Lifetime,’ or even ‘Double Lifetime.’ It sounds good, but often there is very little definition of what exactly lifetime means.

Our window warranty is complete coverage and you won’t have to worry about a bunch of exclusions or fine print. And you have as much coverage in forty years as you do on day 1.
