Comments: We had a small concrete pad lifted to make it level since our AC units were on it and it had shifted over time, was tilting toward the house and water was dripping toward the house rather than away from it. Originally, it didn’t seem to make much of a difference but they called us back and mentioned they were not satisfied with the result and had a new batch of material that was working better (foam like substance) and wanted to come back to correct it and it worked terrific! This company and staff communicates very well, was on time, personable, professional and showed they want their customers to be happy and do the job correctly. I would recommend for any of their services.
