We love our new windows from The Window Source! After years of drafty old windows, our new double-hung windows are doing a great job keeping out the noisy cold wind. They are easy to keep clean and really add a lot of light! John and Donna were easy to work with and answered all our questions without any pressure to purchase from them. Rob and his crew did a great job and replaced all 26 windows in just 2 ½ days! Everyone we worked with was very friendly and professional. We highly recommend The Window Source for any window needs!
Kim McGuire
I can't say enough great things about the Window Source. John installed our windows today and he did a bang up job. He is incredibly knowledgeable about the products he is installing and takes the time to discuss with you all of the different options you have and which products will fit your needs and why. I couldn't be happier with the quality of my new windows and how quickly and efficiently they were installed. If you need new windows, the Window Source of the Rockies is where you want to go. Ask for John and I guarantee you won't be disappointed.

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.
Melissa Simmons
The Window Source of the Rockies - So glad we picked your windows for our house. Beautiful windows, wonderful communications with the company and the installations were professional, custom works. We enjoyed polite and respectful dealings start to finish! Thank you.
Taylor Byrer
The Window source was SO helpful. They went through everything with us so we found the best ones for our home and our budget. We did half one year and we loved them so much we went and replaced our other windows with them the next. Not only were they helpful and lovely windows, but the customer service was great. I called months later to ask about receipts and energy ratings (for tax stuff) and they remembered me and took the time to help me get all the info I needed. I would recommend them to everyone looking for windows!
