Looking to get a patio added on to our back porch. I think it's going to be a hair under 350 sq ft. without removing the cut off corner piece. We are thinking just plain concrete, no staining/stamping/etc. We also have sprinkler system, so that will have to be reconfigured. What would a reasonable cost for this be? Will most companies be able to redo the sprinkler system and do the concrete or am I looking at two different companies? Does anyone have recommendations for companies in BCS?
