Ali came recommended by a colleague and after speaking with him, I gave him the job of redoing my backyard using my own stones, with him supplying some additional materials. I was tearing up the patio and side walkway because of the growth that had come through the stones over the years. He guaranteed me verbally that it would be years before growth started coming through. Originally, the work looked ok when he did it in November but his work didn't even last year and growth came through, more so in the back patio, the following spring. Took almost a year for him to come back and address his work. I was going to get him to do my driveway at that time but reconsidered. Extremely disappointed. Backyard looks no better than before I hired Ali.
