At Bell Rock the old stones lean in the grass, and the city has grown around them a dozen times over without once disturbing the quiet there. Neighborhood Property Services LLC looks after Malden properties on both sides of the calendar: mowing, edging, trimming, and cleanups while things grow, then plowing, shoveling, and salting once they stop. Out toward Maplewood and Linden the lots are tight and the driveways short, which makes precision worth more than horsepower. None of it is complicated. Cut it even, clear it to the pavement, sweep up after, and a property that gets the same attention in February as in June is easy to pick out from the street.
