On a June evening in Berkley the sprinklers tick, bikes lie tipped in the driveways, and the lawns are the color they will hold until August. Jack's Lawn & Landscaping keeps them that way with steady mowing, trimming around trees and fence posts, and edging the sidewalks so every square of concrete shows. Lots here sit small and close together, which means a sloppy job announces itself and a careful one does too. The aim is a yard that looks composed from the street and comfortable to stand in. Berkley, Royal Oak, Clawson, Huntington Woods and Oak Park are all served.
