My concrete sidewalk had a 14 s.f. block that was raised-up from the tree roots below. The block wasn't cracked, but it posed a tripping hazard. In searching for a solution, I came across Thumbtack and was connected to Ken's Masonry. I live in Goodyear, and he came from Chandler to do the job. A lesser mason might've removed the block and poured a new one. Ken saved the block, stabilized the foundation, and it's now level with the rest of the sidewalk. His repair was the best! A new block would've worked, but there's no way it would've matched. Ken did amazing work, and I'd hire him again in an instant.
