Weekday mornings in East Weymouth start with traffic on Middle Street and low sun lying flat across the Bradley Hubbard Reservoir. Neponset Property Services LLC keeps grounds in order through them — mowing, edging, trimming, and the cleanups that keep a property from ever looking neglected. Consistency is the whole game: the same day, the same lines, walks blown clean, nothing left for anyone to notice but the result. Weymouth lawns sit on ledge and sand in equal measure, and reading which is which changes how a yard gets cut. When the maples go over in late fall, the leaves come off the grass and out of the beds before rain packs them down.
