I thought I would have to demolish my front stairs because they dropped 3". A gentleman in home depot recommended a company called Liftec. I gave them a call. Betty was pleasure to deal with, Terry came out explained the process and gave me a quote, very fair and way less expensive than redoing the stairs (patterned concrete). The Liftec crew came on the day they were scheduled to do the work. They were professional, efficient, and courteous. After they were done the stairs were perfectly level and at the height when they were first poured. They also brought the driveway level with garage floor and made sure no water would drain back to the house. The boys cleaned up and left my house the way they found it.
