Stone walls that hold their line.

Retaining walls, seating walls and terraced walls in natural stone and boulder — built on a footing, drained behind and capped to shed water, so they stand straight for decades.

How we build it

The part you never see is the part that lasts.

01

Read the ground

Edgar looks at the slope, the soil and where the water goes — a wall is a structure, not a decoration.

02

A footing first

Every wall starts on a footing on solid ground. A wall built on loose soil leans within a few winters.

03

Drain behind it

Drainage stone and a way out for the water behind the wall — because water pressure, not the stone, is what pushes walls over.

04

Build in courses

Stone is selected, shaped and set course by course, tied together so the wall works as one piece.

05

Cap it

A cap stone sheds water and finishes the line — and gives a seating wall a clean edge to sit on.

The stone

Chosen to outlast the house.

  • Natural fieldstone — hand-split and weathered; walls that look like they grew there
  • Boulders — for terraced and naturalistic walls
  • Bluestone caps — a crisp, durable top for seating walls and piers

Questions

Before you commission.

Why do retaining walls lean or fail?

Almost always water. When the soil behind a wall stays wet, the pressure pushes it out. The lasting fix is a proper footing with drainage behind it.

Does a retaining wall need a permit?

Taller walls often do, depending on the county. Edgar tells you on the site visit whether your wall is likely to need one — before you sign anything.

Can you repair our leaning wall?

Usually the right answer is to rebuild the failing section on a proper footing with drainage. Patching the face of a wall that is being pushed by water only buys a season. See repair & restoration.

How tall should a seating wall be?

Comfortable seating height is roughly the height of a chair seat; Edgar sets the final height with you on site, along with the cap overhang.
