The oak woods of the Waterloo hills hold a hush you can practically hear, and Chelsea sits right at their edge. Sanctuary Lawn and Landscape L.L.C works the ground between that quiet and the road: mowing, trimming, edging and landscape upkeep through the growing season, then plowing, shoveling and de-icing once the cold moves in. Beds mulched in May, leaves cleared in November, a drive opened at five in the morning in January — one property, minded the whole way around. Kept like that, a yard stops being a chore and starts being somewhere to sit. That is the aim, honestly.
