  • The Window Source technicians were very professional. The guys showed up on time and did a great job with installation. They cleaned up inside the house as well as outside. We were very happy with this service.

  • This review has been a long time coming. Over the years, I have contracted out both large and small undertakings in my home. I have learned, that who you choose to commission work done is just as important as what you are having done. Randy, Dee, and their team at The Window Source of Lexington were fabulous to do business with. The excellence in customer service, and work ethic I experienced from the entire team set them apart. I highly recommend them.

  • i had my windows installed by another company. i knew something wasnt right with the installation. so after doing some googling i came upon "the window source" and gave them a call to see if i could get someone to come take a look and just see if my hunch was correct. i talked with Eric and he said to just send him some pics of the job and he would try to help me out. he confirmed that my worries were confirmed and that the installation had not been done correctly. so dont make the mistake i did. just hire these guys as they will apparently install your windows correctly, unlike the company i had used. too bad there is no time machine. thanks again Eric for your help. if we are ever getting windows installed again i now know where to go.

  • I’m a second time customer with Window Source. I got my first window replacement in 2020 regarding two windows, one of which was very badly rotted. That job was affordable and quick, so of course I return to have windows replaced in my son’s room. My house was built in 1998 and most of the windows are original to the house. My son’s room was the coldest room in the house, and the only possible draft was coming from the windows. Again, the replacement was affordable and fast, and the quality is excellent. I just walked into my son’s room this morning on the coldest day of the year and it is now the warmest of every room! I cannot wait to schedule my remaining windows with the Window Source. There’s a lot of windows that need replacing, and so long as my experience continues to be excellent, I’ll be a returning customer.
