Amazing Customers

What They Say

"AJ and crew did an amazing job on our patio. He was super responsive, clear, and honest during the quote process. Fast forward to the project date, the team was here bright and early for clean up, and was poured a few hours later. They cleaned the area up and left everything exactly as it was. I would 100% recommend them for any concrete job."

"We asked Karns Concrete to give us a quote for a patio in our backyard and the approach for our driveway. Jon got back to us right away with a quote and quickly got us on the schedule. The work was done in only two days, and we couldn’t be happier with the final results!"
