The contractor, salesperson, and crew were timely, knowledgable, and professional and knew their stuff. During excavation for the piers, it became evident that we did not have a normal Foundation. But rather a stair-stepped foundation require more work than originally determined. Upon conferring with the company owner, we decided to go ahead and increase the contract price for the additional 5 to 7 workdays that it would take to navigate through all of the additional excavation of concrete in a patio are as well as a sidewalk there was stair-stepped Foundation. The work was completed professional and clean up, including pouring new concrete where the patio piers and sidewalk piers had been placed, was done exceptionally well. We would recommend Mid-America Pearing again based on what we know now.
