What it's like building a wall in Manhasset

Manhasset's terrain is gently rolling for most of the area, with steeper sections on the Plandome side dropping toward Manhasset Bay. Soil is generally clay-loam with good structure for wall foundations.

The Manhasset neighborhoods we work in most: Plandome, Munsey Park, Strathmore, Flower Hill. If you're in or near any of these and need a wall built or replaced, we likely know your street and the soil under it.

The walls Manhasset homeowners ask us about

Front yard accent walls, driveway aprons with grade transitions, pool deck retaining walls, and small-to-medium garden walls integrated with hardscape patios.

// MIKE'S NOTE

Built a small but exacting wall in Munsey Park last August. 28 LF, Nicolock Olde Greenwich, max height 32 inches, with a stepped return to the existing patio. The detail work took as long as the actual block-setting. Came in at $11,800. Homeowner is an interior designer. Worth every minute.

// MANHASSET NOTE Manhasset properties tend toward designed landscapes. Wall aesthetics matter as much as engineering. We work with a small group of local landscape designers and can match the look they're already specifying.
