Last winter, three flagstones became cracked and loose where my walkway meets the sidewalk. This appears to have been due to repeated blows by the sidewalk snowplow. Richard and Bill developed the solution of replacing these three end-stones with sloped concrete. Bill then expertly implemented this solution, which also involved removing the end of the existing concrete pad below the end-stones and pouring a new mini-pad that Bill stabilized by attaching it to the newly cut end of the old pad. Bill ensured that the street-end of the new pad sloped at the optimal angle from the remaining stones down to the sidewalk: shallow enough to avoid being caught by the blade of the snowplow, but not so shallow that the transition to the remaining flagstones would create a tripping hazard for tenants. A tricky job, beautifully done! This is the seventh time that I've used Wilkens Contracting for a range of masonry services. The work is invariably excellent, and the price is always appropriate.
