Anyone who has lived a Rochester Hills winter knows the particular insult of the plow berm — the drive is finished, the county truck goes by, and a wall of packed snow lands across the apron. Ken Jackson Clean Up, Inc. works the hours when that gets fixed, often between midnight and sunrise. Plowing, clearing walks and steps, and salting the refrozen spots make up the work, storm after storm across a long Michigan season. The measure of a good night is a homeowner who walks out at seven and finds nothing standing between the door and the street. Nothing about it is loud, and all of it matters.
