Real, Local Reviews From Happy Customers


New windows are great! Pierce made the process easy from the get-go. The windows even came in a few weeks ahead of schedule and we were and to get them installed in one morning. Mike is a great installer and made sure everything was perfect. We're very happy with the end result and are happy to have used The Window Source of KC. We'll be getting more of our windows replaced with these guys as the needs continue.

Kelsey Ernest

Wow! What a huge difference these windows make in the look & feel of my 1930s home. I am looking forward to lower heating & cooling bills. Pierce & his father Gary were so accommodating from beginning to end I highly recommend anyone who is interested in updating their windows should call Pierce at The Window Source of KC!

Lisa Michaels

A great experience. We needed to replace all 5 windows on the basement and I am so glad we decided to work with The Window Source. Pierce and his team were extremely professional and helpful all along, and did an exceptional work making sure every detail was correct. Would highly recommend.

Michael Délano

We bought our home in the summer of 2020 and we knew right away we needed to replace the contractor grade windows. We found The Window Source by luck and we are super glad we did. Pierce did a great job going through the options and explaining the process of changing out windows. There was no pressure to buy. We ended up going with The Window Source because it’s a family run business. Our energy bill has been about $50 less since the windows were replaced. We would recommend The Window Source and Pierce in a heartbeat.

Merrill Walker

We were getting ready to sell our house and we had two windows that needed replaced. I found Window Source on google and went with them due to their reviews and that fact that they are family owned. Pearce came out and did a great job walking me through all my options. He said the order could take up to 12 weeks. I think they came in around 6 weeks. He called me immediately and worked to get them installed the day before our house went on the market, just in time! He made sure to squeeze us in to help us out on the listing. I would recommend The Window Source and absolutely use them in the future.
