5 Star: Loretta Dorman "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."

5 Star: Brodie Logan "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+++"

5 Star: Erika Webb "Leo was great--recommended windows that we really think are awesome. The team was on time, quick, efficient and did all 10 windows in a day. The noise reduction from our 1963 aluminum windows is amazing. I was expecting to pay almost 2x what the project came in at, so excellent value as well."

I had four companies measure and provide me estimates. From beginning to end, Leo and the installation crew were honest, communicated, trustworthy, detailed and hard working My home was completely transformed with new exterior doors and 26 windows throughout my house. I will definitely re-hire them for my basement windows when the time is right Also, the product is incredible and the price was very competitive and actually was more affordable for better windows that 2 other companies I ran into some issues financially toward the end of the project and the communication was key and Leo was strong with his business but big with his understanding as a family business. https://bit.ly/2TDx6sD
