Fort Collins Replacement Windows

Our Triple-Pane Glass Windows + Our Expert Installation
Means You Get The Very Best Results

Ameritech Windows installs the absolute best home replacement windows in Colorado.

We can confidently say we have the ABSOLUTE BEST windows you’ll be offered because our windows are so different from what most Fort Collins window companies will try to sell you.

It all starts with our triple-pane glass

One of the most important ways our windows stand out is triple-pane glass. Almost all Fort Collins window companies go with lower quality single-pane or double-pane windows, but nothing can match the performance of triple-pane glass.

Triple-pane glass saves you more money on energy month after month, and also keeps the interior of your home quieter. Most importantly, you’ll be more comfortable in your home no matter the temperature outside.

Best-Quality Windows All The Way

Our triple-pane glass is a huge part of the quality of our windows. But it’s not the only part. Our replacement windows for Fort Collins homes:

  • Have super-strong frames reinforced by High Density Resin. (These are not the hollow or foam-filled vinyl frames that most window contractors install).
  • Are beautifully designed, including elegant touches like locks that are not just stuck on top of the window sash, but instead integrated into the sash. It makes for a more attractive window.

Get a warranty You Can 100% Rely On

Just about any replacement window will come with a warranty. And most will sound great – you’ll hear about ‘Lifetime,’ ‘Limited Lifetime,’ or even ‘Double Lifetime’ warranties. But what exactly lifetime means is often left vague.

Even worse, many window warranties have a lot of fine print. Things like “normal weathering” are excluded from protection. Exclusions will weaken your warranty significantly.

The replacement window warranty that Fort Collins homeowners get with our windows is better. There’s not a bunch of fine print or exceptions and you’ll have as much coverage in forty years as you do on day 1.

Who Can You Trust To Install Your Windows?

For peace of mind, it’s very important to find a Fort Collins window installation company with a proven track record. No one wants to find out too late that they picked a contractor that doesn’t get the job done right the first time.

Here’s why you can trust Ameritech Windows to deliver the very best results.

  • 25+ years in business, always under the same continuous ownership
  • A+ rated with the Better Business Bureau
  • Hundreds of 5-star reviews on Google
  • Installers that have a decade or more of experience
