Real, Local Reviews From Happy Customers


We had a fantastic experience with WSI. We got quotes from multiple companies, and WSI was the most reasonable for high quality windows. They installed 12 new windows for us. They were on time to the minute each day, were courteous and professional, and cleaned up after their work. We had windows installed at our previous home with a different company, and WSI was far better both in product and service.

A Very Happy Ending!!
I had new windows and a slider installed almost 2 years ago by a different franchise owner of The Window Source who neither had business sense nor people who actually knew how to install windows and quickly went out of business.
The Window Source Indy opened a store downtown in January and when I called yesterday to ask for help with my windows, they agreed and were here this morning!! Johnny Ray quickly determined what the issues were and is ordering new sashes for a few of the windows and will be installing them as soon as the order arrives.
The fact that this gentlemen is taking time to fix these issues caused by another man's poor work says a lot about him and the product he sells.
If you're looking to replace windows, I highly recommend calling The Window Source Indy--Johhny Ray and his team will do an amazing job!!

Shelly Cornelius

The people at WSI were phenomenal. They are very responsive, always within 24 hours. Once the materials were received, they were very quick and flexible in scheduling our service. During the install process, they were very professional and answered our questions completely. When one of the parts that was received was incorrect, they reordered the correct part and installed it immediately upon receipt. Highly recommend the Window Source of Indy!

Jeff Butts

Johnny Ray and Kim did the installation of 8 Windows in our home. Communication with them was excellent. The installation was done professionally and very clean. Great people to work with.

Karl Mann

They were quick and professional from the first phone call. From setting up the consultation, all the way to the end of install, they did a great job. Very professional and would highly recommend anybody looking to get windows to strongly consider using them!
