Real, Local Reviews From Happy Customers


Highly recommend this business.

I contacted The Window Source of the Carolinas to have my old windows replaced. I shopped around and got quotes from 4 companies, and The Window Source of the Carolinas was by far the best value for the money. The installed windows were good quality and the most reasonably priced on the market, the installation was prompt and professionally done, no BS, no missed appointment windows, delays, and no hidden costs. I would recommend this company to anyone. Greg is a great guy and works with you to figure out what you want/need and what the best choice is for you.

I'll be using them again in the future if my next house needs windows.

I shopped around for replacement windows for my townhouse in Cornelius. I chose Window Source because of price. Even though it took a long time to get the windows, it was worth the wait. (Not their fault, just how it is these days!) The entire team (Greg, Chasity and the techs) were easy to work with and all did a good job. I highly recommend this company.

We reviewed three different estimates for window and door installation before settling with the window source. The sales team was very knowledgeable and explained the rationale for the window types and doors they offer. The had just the right variety of options and offered warranties on the product and installation. The price was fair and the results inside and out are fantastic. I would highly recommend their team from sales, measurements and installation.

I used Window Source Of The Carolinas for some of my rental properties around town this summer. I worked with Michael Cooney, and I am looking forward to calling him back to do some more windows in a few more properties this coming spring. He was easy to work with, extremely personable, and was more than willing to put together a very lucrative package for the various different properties I have. The quality for the price is almost unbeatable and all the work turned out well!!!!! Definitely recommend!!

David Richard

We absolutely love our new windows and are so thankful we made the right choice in selecting TWS! The entire process was smooth, from the initial consultation with Greg to the installation. We can't say enough about Uriel and his crew - they were prompt, professional, efficient and highly skilled. They installed 16 casement windows, 3 fixed windows, 1 sliding window and 1 new sliding door in less than 2 days. We feel like we have a new house and would highly recommend this company for any job - large or small.
