Saturday morning in Berkley sounds like mowers starting one yard at a time, all the way down the block. Diamond Cuts Lawn Service adds its own to the chorus, cutting, trimming and edging until each small lot reads sharp from the sidewalk. The line is where the craft lives: even stripes, square corners, grass stopping exactly at the concrete. In winter that same attention goes to snow, plowing drives and opening the walks a Berkley block expects shoveled. The work covers Berkley and neighboring Royal Oak, Clawson, Oak Park and Huntington Woods.
