Install Premium, Energy-Efficient Windows

Elevate your home design with stunning windows! 

No matter what size, shape or function you have in mind, we can almost certainly find the perfect window for you.

We are not a large multi-state corporation, and we are not brand specific. We work with each customer individually and will guide you towards the manufacturer, style, and possibilities that best suit your vision.

You can get a window from anybody, but what makes a window great is the installation. Does it fit perfectly? Does it achieve what you’re looking for? With decades of experience and first-rate reviews, you can count on us to install your windows so that they live up to the manufacturer’s highest specifications.

Anlin windows are manufactured on the West Coast. This makes their windows affordable to access and safe to transport without any damage. (Long freight trips over mountains can damage the integrity of your glass, so we avoid this.)

Anlin meets the world’s stricter manufacturing standards set by California. To back this up even further, they offer a lifetime warranty that is fully transferable to the next homeowner. The comprehensive warrantee includes service, parts, and even glass breakage.

Soft-Lite windows are another great option. Like Anlin, their windows meet high quality standards including sound-proofing, triple-pane, and weather resistance.

If you’re looking for economy, Alside windows offer great selection, innovative designs and quality craftsmanship at a lower cost.

We Install a Vast Variety of Windows

Single or Double Hung Windows

Hung windows are split into two parts. In a single hung window, you can move the bottom part while the top remains static. In a double hung window, you can move the top and bottom part. Our preferred manufacturers also allow you to tile the windows for easy cleaning.

Picture Windows

Picture windows let in abundant sunlight and are typically the only window on a wall. They remain closed and allow for a beautiful, expansive view of your surroundings.

Sliding Windows

Slider windows are great for giving airflow to tight spaces.
Sliding windows can be single, double or even triple.

  • A single slider will have two sashes. One will remain stationery while you can move ht other left or right.
  • A double sider will have two sashes, but in this case you can move both to create ventilation from both sides. This is a fantastic option for Colorado since our weather can change at a moment’s notice.
  • A triple slider will have three sashes with the outer two able to move inward. This is a great option for larger openings where you want extra ventilation.

Awning Windows

Awning windows are hinged at the top. They open outward, allowing you to enjoy fresh air even while it’s raining.

Casement Windows

Casement windows open from the right or left, allowing you to get fresh air and ventilate your home anytime by simply swinging the window out to the side.

Bay and Bow Windows

Awning windows are hinged at the top. They open outward, allowing you to enjoy fresh air even while it’s raining.

Specialty Windows

Speciality windows add whimsy and flair to your home. You can add dramatic arches, beautiful circles, or quirky angular shapes to accent your architecture and make a design statement. Whatever specialty windows you choose, they’re sure to imbue your home with your unique style!

Why Colorado Classic Exteriors?

We lay tarp. We take care to remove old windows carefully so as not to damage your house.

(Most) everyone does that! Here are a few things we do differently….

We leave the label on until you’ve inspected your windows. Why? We’ve repeatedly discovered that other companies have misrepresented what windows they’ve installed for clients. When you pay for a premium quality window, you deserve to know without any doubt that you’ve received what you paid

If your window isn’t installed properly, it will never perform as the manufacturer advertises. We make sure your window is cut perfectly so as not to leave any gaps between your wall and your window. While installing windows, we’ve encountered numerous instances where the original home builder mis-measured but covered up their mistakes. You can visually hide mistakes, but your window’s performance will always suffer.

Always measure twice. Replacement windows are custom made to fit your house’s openings and we make sure to get a proper fit every time. We achieve this by measuring twice: once when your project lead conducts a job inspection and again by a Final Measure Technician before ordering parts or installing your window. Our Final Measure Techs undergo a rigorous training and certification process, not only to comply with AAMA guidelines but also to meet our founder’s exacting standards.

Excellent and very well done

“We loved the great service we received from Colorado Classic Exteriors. They came out and gave us three price options to replace all our windows. Then the install was excellent and very well done. I would definitely recommend them!”

Joel Newton

Didn't try and sell us more than we needed

“Great experience! Great quality of window for less than the competition. Professionalism all the way around! They have great advice and also listened to what we were looking for. Didn’t try and sell us more than we needed. I’d definitely recommend them.”

David Martin

Extremely courteous and professional

“After multiple quotes from local, big box stores and nation wide window vendors, Colorado Classic Exteriors is our #1 choice. We need 10 of our windows replace due to a large hail storm in Aug of last year and most of the vendors only interested in price gouging us/insurance company. Bottom line up front, if you need an upfront, honest, down to earth, no sale pressure, GREAT Products/Value for your $ and Customer focus then Sherrie and Preston at Colorado Classic Exteriors is your go to company. They replaced 10 of our windows last year and 6 more, phase 2, a couple weeks ago and they are all beautifully done. We will be using them to replace the rest of our windows in the future. Also the installation team, Greg and Greg, are extremely courteous, professional and dedicated to the job above and beyond expectation. Thank you Colorado Classic Exteriors TEAM!”


Friendly, skilled, on-time, professional and down right good guys

“Colorado Classic Exteriors was like a breath of fresh air for us from the start! Meeting Sherri and Preston was such a pleasant experience. They are knowledgeable, professional, calm and incredibly helpful. We never felt pressured or pushed as they educated us on their products. The experience continued to be a pleasant and easy process as we met the window installers. They were friendly, skilled, on-time, professional and down right good guys. Our windows and trim came out amazingly beautiful! They installed THE most beautiful Garden Window for us, too and helped to update our gutters! I would highly recommend Colorado Classic Exteriors for your windows and trim!”

Cindy Schreiber Huxley

Extremely professional

Preston was extremely professional and returned my initial call on the same day. He came out for a bid within a week and gave me an excellent quote. The install took only two days and both installers were competent and curious. The windows have worked out great so far. They actually wrapped the window with aluminum so that I will never have to paint the window frames – the old frames were beyond painting.

We already notice how much cooler it is in the house this summer.

I highly recommend Preston. He is a consummate professional.

Stand behind their work

“This company replaced all our windows two years ago. Very professional and worked through a blizzard (literally) to makes sure the job got done when we needed it to. Fast forward to today and they are extremely responsive in fixing a minor issue with one window and attending to other items we asked about. Courteous, and stand behind their work.”

Lacy Lowrey

Home is now quieter and so much warmer

“All around wonderful experience! From the knowledgeable consultant to the friendly, hard working install team these guys were great. We had all of the windows in the house replaced as well as a slider door and I couldn’t be happier. Our home is now quieter and so much warmer. Thank you for the great experience!!!”

Cole McGinlay

Did exactly what they said they would


“Colorado Classic Exteriors did a great job replacing our windows. They did exactly what they said they were going to do. Thank You, Sherrie!”

Mike Schwabauer

Never felt pressured into anything

“Sherrie, Preston and their team were amazing. They were very professional and friendly. I never felt pressured into anything. Sherrie designed our solution for my desire and need. We had all of our windows replaced and we are very pleased. We noticed a difference right away with how much cooler the house is now and also I noticed how much the outside noise is muffled. I would definitely refer anyone to them. One last comment. Another thing I liked is that they are a local business and who doesn’t like supporting local!!”

Todd Sivers

Experience was superb


We had 11 windows and a sliding glass door replaced. Our overall experience was great. Install completion time was efficient. We were presented a fair price and we like supporting local businesses. My only complaint is that they did not clean up as well as I’d hoped. A couple of examples would be dust and debris left in each window area and they did not patch up all of the exterior paint until asked. I would still highly recommend using them for your window needs.

This is our second time hiring Colorado Classic Exteriors and our experience was superb! We purchased a storm door and entry door. Our cats love the new storm door! Everyone we were in contact with at this company exceeded our expectations by being attentive and answering all of our questions. I especially enjoyed talking with Kathy on the phone, she is the sweetest! If you are looking for windows or doors, this is the company you want to call!


Very price competitive

“Preston is a great and guy and as professional as they get. His crew was friendly and each one of them introduced themselves to my wife and I. The crew was very careful to cover everything and they were very respectful of our things. Everything was delivered as promised and they did an excellent job. They were also very price competitive and Preston even gave us a gift after they were finished with the job. I would highly recommend Preston and his team for anyone looking for affordable windows with excellent craftsmanship and customer service. I will use Colorado Classic Windows in the future and refer them to anyone I meet looking for windows for their home.”

Clearly cares about the quality of their work

“Replaced the windows in our whole house. I can’t begin to describe how pleased I am with every aspect of their work! Highly recommend! This is a family business that clearly cares about the quality of their work and the satisfaction of their customers. Gary, the sales rep, was patient and educational. He was respectful of our budget and helped us get the biggest bang for the buck. Preston, the owner, was attentive respectful, and knowledgeable. James, the installer, was friendly, prompt, detailed, and respectful of our home. Everyone showed up when they said they would, delivered what they promised and were so pleasant the entire time. If anyone wants a reference please just message me. This was honestly the best contractor experience I’ve ever had. Am now a customer for life!”
