I am planning on having a concrete patio installed in back yard and have a few questions. The patio will be 23' x 12' with a small 8' x 2' walk leading up to it. I basically have two questions. I have gotten one estimate for $1500 (more estimates will follow shortly). I was wondering if this seems like a fair price? Also he says that steel mesh is not required for this situation. I was under the impression that you need it for stability? Am wrong or is he cost cutting?
