one of my landscaping customers recently hired a couple of "masons" to come over and redo their front steps, these were just poured concrete. the first time they try to do this, the just mortar on some pieces of slate, and call it a day. they left about a 3/4" mortar line between each of the pieces, the mortar was a different color than the stone, and this was clearly visible, from the other side of the street.as if this wasn't bad enough, they also do some retaining walls, and the top of one of them isn't anywhere near straight, it has a 6" slope to one side.to make it worse, they came back yesterday, and tried to fix their horrible job on the steps. at first , they tried to take up the slate taht they had lain, but after about half an hour, thay give up, and preceed to lay the bricks, right on top of the slate.tonight, i'm gonna go tell this guy that he is getting screwed! tell me what you guys think of all this.
