July empties a Sandy Springs street: families gone for a fortnight, the grass along Powers Ferry growing anyway in all that heat and rain. The Lawn Sitters keep those yards on schedule while the house stands quiet, mowed, edged, trimmed, the walks and drives cleared, so a lawn never lets on that nobody is home. Weekly and biweekly service carries straight through the growing season, whoever happens to be traveling. Autumn shifts the work to leaf removal, done before the drifts pack into the beds and along the gutter line. Coming home to a kept yard is its own quiet welcome.
