What it's like building a wall in Port Washington

Port Washington's defining feature is the ridge from Beacon Hill descending toward Manhasset Bay and the Sound. Slopes are real, especially on the streets running west off Port Washington Boulevard. Soil is sandy near the water, clay-heavy on the hill.

The Port Washington neighborhoods we work in most: Beacon Hill, Soundview, Port Washington Village, Manorhaven. 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.

Driveway and front-yard retaining walls on the Beacon Hill grade, tiered backyards on Soundview properties, and replacements of failing 1960s-70s walls that no longer meet drainage standards.
