Route 41 runs the length of this country at speed, and the properties set back from it hold a quiet the road never gets. JZ Property Maintenance keeps those lawns cut and trimmed through the long Chester County summer, edging walks and drives and handling the cleanups that open and close the year. July here is humid and green past belief; the mowing schedule barely slackens for a week. A yard finished at dusk, smelling of cut grass with the heat finally coming off it — that is the whole point of the day. Work runs across London Grove Township into Jennersville, West Grove and New London.
