I would recommend Concrete Authority to anyone as I have to neighbors and colleagues at work. They did some work for me putting in flower bed edging and a small patio. I am very pleased with the work and have had many compliments on the concrete work around my beds. Concrete Authority was very timely and the work was professionally done. I have had absolutely no issues with the work performed by this company.

I had Michael Netherly do some concrete work at my home on Stuart St in Denver, CO my home at the time was in need of some repairs from a flagstone patio and a concrete patio on the side of my house extended to my drive way. I was very pleased with Mr. Netherly’s professionalism in completing the work. I also was very pleased with the actual work he created for me.  Mr. Netherly comes highly recommended for any concrete work you may need done on your home, and in the future should I have any further concrete work needed on my current home I would definitely have Mr. Netherly do it for me again. I know that he has years of experience and comes from a background in the concrete business this helped to make me very confident in hiring him for the job I needed done.

Michael's work and attention to detail were terrific. Very easy to work with and has an artistic eye and great knowledge of concrete and brick. Michael repaired and stained my beat up old threshold and landing at the front door. It looks great and he improved my curb appeal greatly! He also stained the entire brick facade on my home and made it look brand new!

Susan // Angie’s List

From start to finish, Concrete Authority handled the job to perfection. After my initial outreach, Michael communicated quickly and thoroughly. The project came in on time and on budget. The result is better than I could have imagined and I appreciated the team’s knowledge and ability to work through the nuances of the job.
