See What Our Customers Are Saying About Us

  • “Fantastic Company and true to their word! The crew was so professional and polite. We had our entire house of windows done and it only took 2 days. The quality of these windows are amazing and we couldn’t be happier! Don’t pay the high price that other companies want. This is the real deal!”

    Jennifer Rochester, NH
  • “Excellent service, product, and less than half the price of the other 2 estimates I had. Installer cleaned up after himself and was very professional.”

    Ian Gollahon, OK
  • “The Window Source of Tulsa was recommended to us. We received bids from three window replacement companies. Window source had the best product at the best price. The installation was on time and professional. We were kept informed through out the process. We are very pleased with the final product. About two weeks after the windows were installed I broke the outside pane of one window while mowing the yard. I contacted Window Source and told them what had happened, offering to pay for the replacement. They replaced the window free of charge. They are a pleasure to do business with.”

    Alan McIntyre, OK
  • “Quality windows at an affordable price. Love our windows! Talked to several companies, but The Window Source offered top notch windows at the best price. Sales and installation crew were very nice, knowledgable and professional. They did a great job.”

    M Kinser, OK
  • “The company to use if your needing window replacement, Fair pricing and honest fast work.”

    Tom Reavis, GA
  • “A++ on service! I had a few estimates from other replacement window companies in the area and The Window Source price was by far the best. The installation crew was fast and my windows look amazing. I would highly recommend using them!”

    Jackie N, GA
  • “I checked all of the big box stores Home Depot, Lowe’s, Sear Etc etc. The Window Source of Athens was by far the best and lowest price. Now they say you get what you pay for in quality and workmanship and let me say The Window Source was great at both categories.”

    Anthony G, GA
  • “We are highly satisfied with the quality of the product and the workmanship of the crew who did the installation of the windows. Outstanding work!! I highly recommend this company to anyone wishing to install replacement windows on his home.”

    Vijay Aranke, GA

    Alicia Thomas, OH
  • “We are extremely happy with Window Source. The entire experience from start to finish was a positive one. Eric and his crew were great to work with……very professional and they really wanted to make sure we were happy with the job. We are pleased with the product, the warranty and the price. There were no surprises, everything was done in a timely fashion and in accordance with the estimate. I would highly recommend Window Source.”

    Randy Gonter, OH
  • “Great price. Great warranty. Professional through and through. Will definitely use them again and would refer to anyone. Couldn’t be happier!”

    Ray Kmatz, OH
  • “I shopped several window companies and The Window Source had the best price for quality windows. Don and his crew did a great job installing 12 windows plus a custom window in our entry. Don was very informative and after the job was done, he did a follow up with us. I was very pleased with his work and would recommend him to anyone.”

    Diana Thornton, TN
  • “Just had all new windows installed by Window Source. We can already tell a big difference in energy savings!! They look great – curb appeal and view from inside is spectacular. Their top-of-the-line windows were more reasonably priced than the medium grade ‘big box’ store quotes. Don was professional, knowledgeable, and a pleasure to work with. The windows arrived in the timeframe he estimated and the installation was painless.”

    Doug & Suzanne Abbott, TN
  • “Replaced majority of windows in the house. Reasonable prices, fast delivery, professional installation. We’re very happy and so glad we chose them over the many other quotes we received. They were easy to work with and made it a great experience.”

    Travis Burden, CO
  • “Nationwide franchise owned by a family here in Southern Colorado- they did a great job from the initial consult to maintaining communication throughout the process. In October of 2016, every other company was out 10-12 weeks for install, but the Window Source owner has been installing windows for decades and were only 3 weeks out. Install went really smoothly, and were able to put in 8 windows in a day. I’d use them again and recommend them to anyone looking for a professional and reasonably priced window install.”

    Brian Kwan, CO
  • “The Window Source is a great company to work with. The wait time isn’t long and they do an awesome job. We had 3 windows put in our home and because we loved them so much we got the rest of the house done. We love the quality and the look of the windows. I would recommend The window Source of the Rockies to anyone.”

    Brenda Woofter, CO
  • “Great workmanship and service. Price very reasonable. Thanks guys!”

    Allison Vernon, CO
  • “Window Source replaced all of our windows and entry doors. I could not be happier with the outcome. The pricing was more than reasonable compared to other quotes we received and the professionalism was Top Notch!”

    Erica S., VA
  • “Working with Chris and the team at the Window Source was fantastic. It’s exactly the experience I hope to get with everyone I work with. The team was extremely informative, professional, and punctual. Everything went without a hitch, they did a great job, and ultimately I am a very happy customer. I definitely recommend working with them.”

    Amir D., VA
