October in Seal Harbor turns the oaks the color of old copper and drops half of them into the yards with the first hard blow. Loyalty Lawn Service LLC follows that calendar: mowing through the last warm weeks, then edging, raking and hauling until the lawns lie flat and open for winter. Summer here is compressed into a handful of bright weeks, and a yard kept even through them is a yard someone actually sits in. The reward is in the finish, a clean strip along the granite steps and a lawn that stops exactly where it should. When the shore road empties out in November, the properties still look tended.
