What it's like building a wall in Lloyd Harbor
Lloyd Harbor's terrain is some of the most varied on the North Shore: kettle hills, glacial moraine, and waterfront bluffs all within a single village. Lots are large, slopes are real, and the soil shifts dramatically across a single property.
The Lloyd Harbor neighborhoods we work in most: Lloyd Neck, Lloyd Harbor Village, Caumsett area. 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 Lloyd Harbor homeowners ask us about
Estate-scale retaining walls (200+ linear feet is common), driveway walls on the long winding entries, slope stabilization on the bluffs, and stormwater management walls tied into dry wells.
We installed a three-tier garden wall in Lloyd Harbor last fall. Total run was 96 LF across the three levels, Nicolock Olde Greenwich blend. The owner wanted the lower tier planted with mountain laurel and the middle tier with hostas. Job took 9 working days and finished at $43,200. The drainage tied into an existing dry well at the property's southeast corner.
