I waited 6 weeks for someone to come by and give me an estimate to raise a sinking front step. In the meantime, I contacted other concrete repair companies. 1 was a No-Show, 2 offered to fix the entire driveway at an exorbitant cost, 3 said they didn't do mudjacking only total replacement, and 1 sounded very arrogant on the phone. I was totally discouraged at the difficulty in finding someone who could work with us. When Ron Bowen from A-1 Concrete finally came, it was such a welcome surprise. He was polite and professional. He patiently explained every step of the process and said that if I wasn't happy with the result, he would redo it at no charge. His team came by a week later, thanks to a cancellation. The whole process took about 45 minutes. The team was polite and cleaned up. The 6-week wait for the estimate was worth it.
