September comes off the Sound mild and long, and Mount Vernon lawns get a second green out of it. P&A Home General, LLC spends that stretch mowing, trimming close to steps and fences, edging the walks, and clearing the first leaves before they settle in for good. Grounds work on these narrow city lots is about what shows from the sidewalk — the border held straight, the corners not skipped, the driveway swept before the truck pulls away. Spring and fall cleanups take the rest of it out. It is a good way to keep a house looking like somebody is home in it.
