When the thaw comes, the water over the falls at Carthage runs hard enough to hear from the street, and the north country starts trading snow for mud. TnT Property Services LLC works both sides of that changeover — plowing and clearing driveways all winter, then mowing, trimming, edging and tidying yards from the melt through the last leaves. Spring cleanup here is genuine labor: sand, branches, the wreckage of a Jefferson County winter, all of it off the grass before the first cut. Winter is the opposite sort of effort, done at odd hours with the headlights on. A property carried cleanly through both is the whole ambition.
