The miles of blacktop road that used to serve the old ammunition plant east of Charlestown are quieter now, folded into Origin Park and a scattering of newer businesses, but a lot of that pavement still needs the same care once winter sets in. Lewellyn's Blacktop Sealing spends its summers laying down fresh sealcoat on driveways and lots around town, and its winters protecting that same work by keeping snow and ice from working into the cracks a hard freeze always finds. Charlestown's grid of older downtown streets holds onto shade between the buildings, so a freshly sealed driveway there can hide a layer of ice under fresh snow well past when the open lots have cleared. The crew treats every sealed surface with that in mind, clearing carefully rather than scraping hard enough to chip a good seal coat. A driveway that comes through winter with its blacktop intact, dark and smooth under a final dusting of snow, is the payoff for a summer spent sealing it right.
