I found Gilbert -Z Concrete, in the dead of winter and below zero. He came and did several jobs (other than just concrete) but, including pouring a concrete pad for a shed. I let him use his common sense and knowledge to do what he thought best. I trust him (left him a key) didn't have to be there every minute, I didn't check in or watch over him, and I was right, He knew best, and had better ideas. I have hired him again with the same excellent results. And I will use him again. I gotta say, also, it cost me a lot less than I thought it would. I would not only recommend but, encourage others to use Gilbert, Z Concrete. one satisfied customer here.
