Saturday morning on Leigh Avenue is mowers and screen doors, a block waking up in its own time, and the yards over on Birch Avenue are small enough to walk end to end in a minute. Guzmans Landscaping Services LLC does the close work those lots ask for — trimming around fence posts and porch steps, mowing that leaves no missed row, a border along the walk that a neighbor notices. Small yards hide nothing, so nothing gets skipped. Spring and fall cleanups keep them from getting away from anyone. Princeton, Lawrenceville, Ewing, Hamilton and the blocks between them are the range.
