What it's like building a wall in Setauket

Setauket's terrain rolls gently inland and steepens toward the harbor and Conscience Bay. Soil is glacial till with sandier pockets near the water. Many properties here have mature trees and existing landscape that walls have to work around.

The Setauket neighborhoods we work in most: East Setauket, Setauket-East Setauket, Old Field border, Poquott. 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 Setauket homeowners ask us about

Driveway walls on the older Setauket streets, garden retaining walls integrated with patio hardscape, slope stabilization on the harbor-facing lots, and replacements of decades-old timber walls.

// MIKE'S NOTE

Built a natural fieldstone wall in East Setauket in summer 2023. The owner wanted it to match the existing 1940s stone foundation on their house, so we sourced field stone locally. 44 LF, took 11 working days because of the hand-fitting. Came in at $28,800. It's our prettiest wall on the Island.

// SETAUKET NOTE Setauket falls under Town of Brookhaven for permits. Brookhaven's review is generally efficient but their drainage requirements are specific. We design wall drainage to their standards out of the gate so the permit doesn't bounce.
