    We just had The Window Source install 6 new windows and a sliding door. They look fantastic! All the windows are triple pane and are very efficient and high quality. The fact that they were about 1/2 the price of the competition was a sweet bonus! Aaron and his team did a great job and showed up on time and were very professional. And no high pressure sales tactics – very refreshing. I would recommend The window Source to all my friends and family.

    I am so happy with our new windows and new door. Ben installed everything for us, and he did an amazing job! I cannot say enough about the installer, he was on time, professional, fast, and his quality of work is superb . His work ethic is none like I’ve ever seen. We will definitely be using The Window Source again in the future!

Down to workmanship, Ben Ryman was amazing installing my windows. I felt very comfortable with everyone who was Involved. If you want excellent quality windows, customer service and installation for the price, I highly recommend The Window Source.

    Great experience even given the unpredictable product delivery industry this past couple of years. Lots of communication and they were there when they said they would be and finished on time. Ben installed the windows and was polite, efficient and so knowledgeable. Professionalism from top to bottom!
    Jeanne Marriott
    Had several windows including a slider door and large picture window replaced. Ben and Andrea were very pleasant to work with. Very professional. Cleaned up everything while they were working and after as well. I am so happy I went with Window Sources of Western Michigan.
