When to Replace Your Windows in Centennial

Upgrading your windows at the right time can improve comfort, energy efficiency, and your home’s value. Watch for these key signs:

  1. Drafts or Uneven Temperatures
    If you feel cold drafts or notice inconsistent temperatures in different rooms, your windows may no longer be sealing properly.
  2. Higher Energy Bills
    A spike in your energy costs may be caused by inefficient or aging windows that let heat escape.
  3. Difficulty Operating Windows
    Windows that stick, won’t close fully, or have locking issues are not just inconvenient—they can also pose safety concerns.
  4. Visible Damage
    Cracks, warping, or rotting frames are clear signs your windows need replacement.
  5. Condensation Between Panes
    Fogging or moisture trapped inside the glass indicates a broken seal.
  6. Excess Noise
    If outside noise is easily heard indoors, your windows may lack proper sound insulation.

Real Reviews From Our Clients

“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,”
Mr. Hoh ★★★★★
"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!"
Jeffery M. ★★★★★
"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!"
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!"
Adrian S. ★★★★★
"We had a very positive experience with Ameritech. They came out to see us several times in order to fully answer our questions. They were kind, courteous, and knowledgeable. In comparing Ameritech doors to other doors, Ameritech doors have phenomenal qualities and offer some amenities that other door companies don’t. We proudly display their front door and look forward to purchasing a back door as well. "
David S. ★★★★★
"Ameritech installed windows for our large remodel project in Fourmile Canyon. Old mountain homes are not easy places to work. They did a great job on the install and were more responsive than your average contractor when we had questions about timeline, U-factor (for County questions...), etc. Overall definitely recommended."
Michael K. ★★★★★
"I had my upstairs bedroom windows replaced a few months back. The windows are awesome, and very energy efficient. I love them so much I’m having my downstairs windows replaced too. The installers did a great job and were very fast and friendly. "
Ken W. ★★★★★
"I have worked with Ameritech a couple times now and they are outstanding. They will be getting a call for future projects. They are the best in the Denver Metro area."

Centennial Replacement Windows

Ameritech Windows installs the very best windows in Colorado. Centennial homeowners who want the windows that are far superior to typical replacement windows will be thrilled with the results we deliver.

The fact is that most windows being offered aren’t nearly as high-performing and energy-efficient as they should be. For example, most windows on the market are double-pane windows. The windows we install all come with triple-pane glass, giving you maximum in-home comfort and energy savings.

Before making any final decision on window replacement, Centennial homeowners should reach out to us for a free quote – you’ll be able to see for yourself the amazing quality of our windows.

Triple-Pane Glass Has Lots of Advantages

Most Centennial replacement window contractors are selling single-pane and double-pane windows. The performance of triple-pane windows is truly superior. Triple pane means you will:

  • Be more comfortable in your home.
  • Save more on energy costs
  • Have significant noise reduction, resulting in a quieter and more peaceful home
  • Have a more secure home since triple-pane glass is harder to remove or break through
  • Other services: double-hung window installation

Amazing Quality Replacement Windows

As important as triple-pane glass is for a best-quality window, there are several other important things that make for a great window. Our replacement windows for Centennial 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.

What Makes For a Good Window Warranty?

Every Centennial window company is going to tell you they have a warranty. A lot of these warranties sound good at first, with names like ‘Lifetime,’ ‘Limited Lifetime,’ or even ‘Double Lifetime.’ 

However, it is important to dig into the specifics and ask important questions. What does lifetime really mean? A lot of time it is not well defined. There’s also a lot of exclusions and exceptions in many warranties that significantly weaken the warranty.

The windows we install are different. They come with a totally reliable and completely defined warranty. Centennial homeowners who choose our windows get a warranty that doesn’t have loopholes or clauses that undermine the coverage. And you’ll have as much coverage in forty years as you do on day 1.

Select a Proven, Experienced Centennial Window Company?

One of the biggest worries homeowners have when improving their home is finding a company they can trust. It is a valid concern. 

Even contractors with good intentions sometimes don’t have the professionalism or experience to deliver the kind of results that you deserve when you are making an investment in your home.

The smart thing for any homeowner to do is look for a Centennial window company that can prove it has a real reputation built on true facts. Here is what to know about Ameritech Windows:

  • 30+ 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

Replacement Window Financing in Centennial
