Winter mornings in Claremont start dark, with the clock tower downtown lit above a street nobody has driven yet. Levesque Boys Landscaping is already moving — plowing driveways, clearing walks and steps by shovel, spreading sand and salt on the slick approaches that a hillside city makes plenty of. Come the thaw the same routes turn green again, and the calendar fills with mowing, trimming, mulch and cleanups at either end of it. Two seasons, one list of properties, and the same idea behind both: finish the job and leave the place better than you found it. By the time most people are up, the drive is open and the walk is safe.
