Some mornings the fog sits on the reservoirs south of Mahopac and does not lift until nine, and the crews work through it anyway. Landwork Contractors, Inc. keeps properties across this stretch of Putnam County in order: mowing and edging on a weekly rhythm, shrub and hedge trimming, mulch, and the heavy cleanups that bookend a growing season here. Winter turns the work over to plowing, walkway clearing and ice treatment on driveways that climb and curve. The land does not make it easy — rock, slope, big trees, weather that changes its mind — and that is exactly what makes a finished property feel earned. Mahopac and its neighbors, all year.
