DO NOT BUY CONCRETE STAIRS FROM THIS COMPANY: Concrete stairs falling apart after almost 3 years. Cost $650. Contacted salesman who looked at the stairs and agreed they were deteriorating. These stairs have 1 year guarantee. I expected the stairs to last a lot longer. No satisfaction from the company. They offered a "patch" which they will not guarantee, and will not put on the stairs to fix them. No resolution to the problem.
