Along the Route 5 corridor the grass strips and green islands between businesses take a beating from traffic, sun and road grit, and they still have to look cared for by opening time. Extreme Property Maintenance & Seal Coating handles that end of Sullivan — mowing storefront and roadside lawns, trimming tight around sign posts and light bases, edging the border where turf meets pavement so nothing creeps. Midday in early autumn, with the mowers running and the maples starting to turn behind the buildings, the corridor gets its shape back one property at a time. Homes on the side roads get the same attention, on the same schedule. Neat ground reads as an open door, and that's the point.
