Clare Pasquesi Google review · September 2026

Had a great experience using Pro One Builders. We had a complicated job wrapping the exterior brick around our windows. Teresa and her team did a great job of taking their time to make sure everything was done properly the first time. I would like to give a special shoutout to Stephan. His expertise and creativity really helped get the job done the right way after a few initial complications with the original plan. Highly recommend using Pro One Builders for your next project.

Charles Cafaro Google review · September 2026

Pro One is an excellent contractor. From their salesperson, Bill, to their workmen I found them professional and accommodating in every way. Special shoutouts to Daria, their decorator, who walked me through every step of the way and truly brought my vision to life and to Stefan, in charge of crews. Responsive to my every request. Superior workmanship.

I hired Pro One for some touch ups and updates to my newly purchased home. They were prompt and fair in providing and estimate and I’m very happy with the quality of their work. Once started, they were efficient in the work throughout the home. They also made sure to give clear communication on any updates to the work they’d do and the price update. Would gladly use them again.

Peter Doukas Google review · September 2026

We've used Pro One Builders for multiple (5+) projects at our house in the western suburbs of Chicagoland. Those projects include finishing our full basement, deck cleaning and painting, concrete step removal in our garage and near our front door, professional painting in multiple levels of our house including using scaffodling for high entry way, full kitchen/powder room/butlers pantry remodel, and hardwood floors throughout our main level along with wall removals. Along each step of the way for these projects, Pro One has been a pleasure to work with. We continue to come back to them for projects at our house due to their ease to work with and high quality of finished work they provide. We couldn't be happier with what they've helped transform our house into over the years and highly recommend them to any friends and neighbors that ask us about the beautiful home improvement projects that we've completed at our house. 10/10 would recommend.
