The nastiest mornings in this corner of Massachusetts aren't the deep snows — they're the ones that fall as sleet and set up like glass on a sloped drive. North Central Power Washing runs winter service for that Leominster reality: plowing, cutting walkways open, and salting the glaze before anyone tries to cross it. A storm gets measured by the clock, not the ruler, and being early is most of the job. When it's finished, a driveway is dark and dry and completely unremarkable, which is exactly the point. Leominster comes first, then Fitchburg, Lunenburg, Westminster and Sterling.
