#1 Window Company for Colorado Front Range

Home / Why Us / FAQs

Since 1994 – that’s more than a quarter century! – we’ve been installing the very best-quality windows and doors for Colorado Front Range homeowners. After thousands and thousands of successful projects, we’ve established ourselves as the completely reliable choice for getting the BEST windows installed on your home.

We’ve been a fully accredited business with the Better Business Bureau for 25 years and they have awarded us their highest rating of A+. We also have over 600+ Google Reviews, the overwhelming majority of which are 5-stars.


A good warranty is clear, honest and not pro-rated. And here’s what most Colorado Front Range homeowners are never told: most window warranties that claim to be “Lifetime” have way too much fine print and too many loopholes.

We’ve seen window warranties from other companies called just about everything: Lifetime, Limited Lifetime, “Double” Lifetime, and more. But the bottom line with these warranties is that there are too many exclusions.

To give you an idea of how bad these warranties can get, we’ve seen some warranties that exclude coverage for “normal weathering” in the fine print. If normal weathering is not covered, that’s virtually no protection at all!

Ameritech Windows’s Window Warranty is not pro-rated. You’ll have the exact same coverage in forty years as you do on day one! Our warranty covers both the frame and the glass, and we don’t have a bunch of exclusions – this is real coverage you can count on. For more on our rock-solid warranty protection, please visit our Window Warranties page.

We make it easy to schedule a free quote – go here to get an appointment. When you schedule free consultation and quote, we come to your home to educate you on window replacement and why we believe no one will offer you a window of comparable quality. We also schedule ample time for our consultant to be in your home – we respect you enough not to be rushing on to the next job.

Our installation team is all about attention to detail and precision. EVERYBODY on our team is a skilled installer with the training and experience to install your window to the HIGHEST standards. Our installation manager has been with Ameritech Windows since 1995 – 24 years and counting! Our top-quality expert installers work together as a team and most of them have at least 10+ years’ experience – some have more than two decades doing this work! Our company ONLY installs windows and doors, meaning our guys are super experienced specialists who know everything about window and door installation. Colorado Front Range homeowners should always be cautious about who is installing their windows. There is a lot of turnover at many window companies and the person doing your installation may lack experience. Our reviews often mention how much homeowners like our installers – these guys are friendly, respectful, and leave the work area cleaner than they found it!
Custom windows fit the existing opening perfectly. They fit your opening like a glove whereas the pre-made, standard-size type fit more like a mitten. Custom windows will cost far less over the course of time. The price of standard-size windows sometimes cost less in the beginning, but other expenses and factors such as additional labor and the disruption to the home far outweigh the initial savings.

Our windows go WAY beyond normal energy-efficiency. The biggest key is that every window Ameritech Windows installs is a triple-pane window. This is so important because the glass package in your windows is FAR AND AWAY THE MOST IMPORTANT factor in how energy-efficient your replacement windows will be.

This is completely logical when you think about it. Energy mainly escapes from your home through glass, and our triple-pane windows keep your home much more comfortable and energy-efficient than typical windows – even well-known, decent quality brands. For more about the efficiency of our replacement windows, please visit our Energy-Efficient Windows page.

Absolutely yes! Many of our homeowners choose us for our triple-pane windows because of the comfort and energy efficiency benefits, and then are pleasantly surprised by another bonus of significant noise reduction. These triple-pane windows will have you enjoying the peace and quiet inside your home.
No they are not. Homeowners get this impression because MOST of the windows available on the market ARE pretty similar. In fact, it is not unusual for several different Colorado window companies to sell the exact same window from the exact same manufacturer! But we have a truly exceptional window. Homeowners who have compared our windows to other choices are completely blown away by the difference in quality. We hope it doesn’t sound like bragging, but we truly believe you shouldn’t make a decision on replacement windows, patio doors, or entry doors until you’ve seen what Ameritech Windows offers. There is NO risk to you – why not request a free quote by clicking here before making any final decision?
