The Window Source of the Rockies is the best window company you could ask for. John and Donna are fantastic. Their installer, Jesse, is professional, polite, and does very clean work. They are always very responsive and take care of everything right away. We replaced all our windows and sliding doors in our house and we couldn't be happier with the end result. The windows and installation are of superior quality. We also had a noticeable noise reduction in the house with the new windows.

John and Donna are always a pleasure to work with. They provide great service with accurate estimates (both time and cost), no unwanted surprises. I had all windows and doors replaced by Window Source over the course of the last few years.

So glad John and Donna at Window Source was the contractor for our insurance claim. They were very helpful, patient and fair during the whole process. James, the installer was quick and efficient while respecting the property.

Much better product than the big-box stores.
10 out of 10. We will be returning for replacing our other windows in the future.

The Window Source of the Rockies did an amazing job. They were efficient and affordable. Donna hooked us up with a quote and she explained the entire process from start to finish in great detail so we knew exactly what to expect. She also advised us in which windows would be best to install in our old, 1800s fixer upper, that would help keep the charm and integrity in tact but still providing us with a new, sleek window.

John did a wonderful installation job and removed the old windows and installed over 30 windows effectively and efficiently. They were kind and communicative. I highly recommended using The Window Source of the Rockies for all of your window needs!

We had our windows done with Windows Source of the Rockies and we couldn’t be happier! Not only are the windows beautiful, but we have noticed an immediate difference in the comfort of our home. Plus, their bid came in considerably less expensive than the other companies we checked out and their staff was thorough, courteous, and professional. I couldn’t recommend them enough!

Our window install was seamless! The installation team was fantastic. I already notice the difference in efficiency in our home. The windows are great quality, and there is a lifetime warranty. You literally cannot beat the price! We had 6 quotes, and the Window Source beat all other quotes out by a significant amount. So happy with our windows!

We had a wonderful experience with The Window Source from the start. John did an excellent presentation to show us how efficient our new windows would be. We replaced every window in our home besides one. We did have to wait a little longer than expected for the windows to arrive, but it was so worth the wait! Jesse and his dad were very pleasant and easy to work with during the installation process and finished the job in 1.5 days. Thank you!

I always had great communication from the beginning with start. My consultation was smooth and straightforward through the entire process. We received a military discount, and had a very fair price for the windows at my condo. I had exceptional communication, and my questions were answered any time I called. Installation was great, and the job was done in a timely manner from when the windows were delivered to them. I am pleased with every part of this process, and would recommend them to anyone!

Don't wait, hire them! Amazing company! Customer service is top notch! I highly recommend them! Friendly, local company that you won't regret doing business with. We have had all the old, ugly, original 1997 windows in our house replaced and awaiting on the last huge window to be replaced. Our new windows look wonderful and we have noticed a sharp dip in our electric bill and steady temperature of our house. By far one of the best companies I have come across! They genuinely care about their customers.
