I just completed a whole house window replacement project with CWS. Good quality windows and a competitive price..good installation, experienced folks on both sales and installation ends made thiigs go smoothly. We have had two houses done by them now actually and the first is still issue free for over 10 years. Installation went fine with the crew showing up on time, professional.. cleaned up well etc.. there's a lot of stress in deciding on replacement windows; I would recommend getting a bid from CWS.

I was initially upset that CWS would not do just a couple windows that were damaged during a storm. We then decided to replace all the remaining windows which I’m glad we did. I contacted CWS since we used them before. CWS did a great job, the windows look great and match the other windows they did a few years ago. If you want great / affordable windows, contact Colorado Window source .

The folks at Colorado Window Source did a terrific job with our Hardie siding. We upgraded from hail damaged vinyl and the additional cost was worth it. You know more severe hail storms will be coming. The price was fair, the communication was solid, the customer service is outstanding. The installation crew did real quality work.

You know more severe hail storms will be coming. The price was fair, the communication was solid, the customer service is outstanding. The installation crew did real quality work. I have a neighbor with Hardie from another company and our installation is much better. There was a real focus on getting the details right. They are responsive and careful. We recommend them highly.

I had some hail damage to my house last year and I was lucky enough to hire Leo and his team to install 9 windows and a sliding door. I am really pleased with their work. My insurance company was giving me problems on the reimbursement. Leo provided the commentary that assisted in a reimbursement of 100% of my request. He even found additional damage on a door that was missed by insurance company. He’s an expert. I purchase Anlin windows which I thought would be the same as my previous windows. Boy, was I wrong. There is a night and day difference in amount of UV rays that these windows filter out. This should really help out on my AC bill. Lastly, I need to give recognition to the installation team. They did a great job and completed the installation of everything in about a day and half. Colorado Windows Source are good people. I highly recommend them. Less

Completed on time and according to our agreement. I would recommend them to anyone needing glass work.

I was very pleased with everyone that I interacted with at Colorado Window Source. They worked with me to accommodate the tenant in one of my units and completed the work on that unit in the time promised. They showed up on time, were professional and let me know if there were any issues while they were installing the windows.

Amazing company and even better people. Super professional and did a super job.

Wow!!! Colorado Window Source are amazing. Super responsive, professional, accurate service from a really great team of people. We’re flexible to work around my schedule. I left for work with old windows and I came home to new ones. They didn’t leave a single trace of them being there either. Would definitely recommend to anyone and I will most definitely be using them in the future!! A+++

The team did a great job installing new windows at my child care center. They were fast, friendly, cleaned up daily, and the new windows look amazing!!

Colorado Window Source replaced 36 windows for me in a commercial building. I was very impressed with the entire process. Their pricing was very reasonable. The service was great. The windows look amazing! I would highly recommend Colorado Window Source for commercial or residential windows.
5
We worked with Leo who is very knowledgeable about windows, installation and features. He was great to work with and helped us make choices that we probably wouldn't have considered and we're really happy we did. No more hanging out of the upstairs windows to clean them!
5
We replaced our old aluminum windows and sliding door and after shopping around quite a bit we found CO Window Source was the best value. The installers did a great job and we couldn't believe how quickly they were able to get the windows replaced! We couldn't be happier with the end product!

We have worked with these wonderful folks for many years. Many of our clients have too. A kitchen window we replaced (old metal one) leaked cold air so bad we had to wear a sweater. Now the temperature near the window is only 1-2 degrees different from the rest of the house SO happy.

The quality is good, the value is good, and our representative was very responsive with all of our questions. We were very pleased with our experience with them.

Best windows to insulate and reduce noise.

They did a great job replacing our old aluminum windows! Very fair pricing compared to other estimates we got. Fast work installing them, too. Only trouble we had was with the city building inspection, which was an issue with the city's process.
5
After getting a number of quotes, I decided to with Colorado Window Source because they were very informative and to the point. I did not have to deal with pushy salesmen.
5
Excellent attention to detail with great suggestions for enhancements!
5
Great experience. Windows have been awesome and insulate very well as our cooling bill has been much less than before. The installers did a great job as well and made sure the process was thorough and complete. If I could do it over again, I would still have Colorado Window Source install the windows. Highly recommended!

These guys go out of thier way to do a great job. Seamless and we never worried about anything, they are extremely organized and great attention to detail. Recently this week they put windows in a duplex I own and it was quick and precise and they even fixed something I didn't even ask them to do. Love all of the crews, very nice and respectful and you would not even know they worked here it was so clean after they finished, except that we have these beautiful windows. Thank you and I highly recommend Colorado Window Source for any project. Less

We had an amazing siding experience, from start to finish, with Colorado Window Source. Victor as not only a wonderful salesman, but also down-to-earth, friendly, and honest. We plan to work with them again for our window project soon!

The product is great and the installers did a good job and were very efficient and friendly

From the salesman, Victor, to Mitch's installation team and all the way to the office manager, Leo, this company has been professional, helpful and fantastic to work with. I will absolutely use them on my next project!

The team is awesome and respectful. Great value. Great work. Would definitely recommend and use again.

I had windows installed from Window Source in December 2017. I was very pleased with the quality of installation and the windows have performed very nicely. If you want to get windows at a reasonable price that are high-quality, go with Window Source, you will be happy!
5
We are delighted with our new windows. They were installed in a timely fashion. The price was right. We now have a warmer upstairs than ever before. We will be interested in seeing how much this reduces our heating and A/C bills in the coming year. I am sure this installation will pay for itself. We also love the new modern look. What a nice improvement for our house.

Colorado Window Source Denver is an amazing company. Scott came to a rental property we have and fixed a window that was installed 10 yrs ago. He was extremely helpful. Colorado Window Source will be the company we will utilize for our Denver properties.

We got an amazing Deal thanks to Leo!!! We got bigger, better windows for less than what we would have paid at Home Depot!

Jim and Bill did a professional install on 3 windows and a sliding door. They also installed a new screen on another sliding door. They noticed that other sliding door wasn't sliding right.

One day, 11 Windows, Done! BOOM! Mike and his father did a great job getting the windows in and out. They are absolutely beautiful! Prices were even cheaper than Lowe's or Home Depot! Call Leo for a quote!

I spent a very large amount of time interviewing window companies and windows before choosing CWS. They came in with a higher line window (Vanguard) at a lower price!!

I spent a very large amount of time interviewing window companies and windows before choosing CWS. They came in with a higher line window (Vanguard) at a lower price!! It almost scared me away (too good to be true?) but they were the real deal. the business model they use is best quality job at lowest possible price. Tisha was extremely patient with my l o n g email and phone communications. I was very nervous as windows are not cheap and this was a good chunk of money for me. Mike came out to measure and we got all the ducks in a row, ordered the windows and set up an install date. The installation crew (Mike again) came out and got down to business. They were fast and professional; cleaned up well after themselves and were conscientious about my property. We had one small problem that was important to me. One casement window opened in the wrong direction. Scott, an owner, REFUSED to accept my final payment until the new window was ordered, manufactured and installed at no extra charge. I am impressed. We plan to replace our porch and basement french doors soon with Vanguard sliding doors. Wanna bet who I will call first! The Vanguard windows are a better quality window. I have noticed that they are MUCH MORE QUIET than the original double pane windows were. I also notice that the heat of the sun through them is noticeably less. I am not sure but i feel that the furnace is not coming on as often now that the November weather is here and when I touch the window frames they are not cold even when it is 30 degrees out. Very happy with these windows and the installer. Do yourself a favor and make them one of the bids you get. Don't go with the companies that you see constantly advertised. They are good windows but FAR more expensive. I think you will be please with Vanguard windows and Colorado Window Source as your installer. Less

My wife and I are really glad we used Colorado Window Source. Not only are they great windows, but the installers paid attention to details and cleaned up after when they were done.

They are built in Loveland and when completed Tony came out to install it. He is a craftsman with attention to details and quality. I will post followup reports as they continue their one year inspection on the door and installation. A+ all around. I will be looking to these guys for further window upgrades in the near future.

He was very personable and professional and answered all of our questions. Our order came in quicker than expected and we booked our install shortly after. The installers arrived right around the time proposed and immediately got to work.

Our overall expectations were exceeded - I highly recommend Colorado Window Source. Less

I had a hail claim and met with Steve about our windows. They were very easy to work with and provided us with an awesome window that priced comparably with what the insurance company was paying which was a huge worry for us. They were knowledgable and courteous which we appreciated. I had some poorly installed windows that where not part of my claim which needed work. The windows were measured wrong originally and I asked for a quote to redo the trip and flashing on the outside. The Rep stated that was not the appropriate action that needed to be done as the windows were the wrong size and covering up the gap would be considered poor workmanship and they would not attempt something like that. It would eventually lead to leaks etc. I stopped and thought for a second and came to the conclusion that these guys had a very strong pride of workmanship and instead of doing whatever to get my business they took a stand and I totally respected that. Other window companies that I had look at my windows all said they would redo some trim and add caulk to make me happy. I hired Colo Window Srce and the windows look awesome and we are very satisfied with our decision. Less

Colorado Window Source is the right way to get your windows done!! They know and understand windows. They are very helpful with selecting the right window for your home.
