The cold that comes off the Sanitary and Ship Canal has a way of finding sidewalks at dusk, turning an afternoon of melt into a sheet of ice by six. Tapia Landscaping Inc. & Snow Service works against that clock all winter — plowing drives and lots, clearing walks and steps, and salting so the thaw-and-freeze cycle never gets a foothold. February in Stickney is rarely about one enormous storm; it is about repetition, and about surfaces that stay walkable in between. There is real care in a set of front steps a neighbor can take without thinking twice. That is the point of the whole season's work.
