April in Ogdensburg is mud and brick and meltwater running down Ford Street toward the river. The grass underneath is still flat and gray, waiting its turn. Mercury Handyman Services picks things up from there — spring cleanups, mowing once the ground greens, trimming, edging, and week-to-week upkeep that keeps a property from sliding. Small jobs done properly add up to a house that plainly looks lived in and looked after. Work is centered in the city and reaches out to Lisbon, Heuvelton and Canton.
