Stone Walls in Durham, New Hampshire.

A wall in Durham is a drainage structure before it is a stone one. Tidal Oyster River frontage and wooded uplands above Great Bay sit on marine clay and glacial till, wet where the land falls to the estuary — and that is where a wall lives or dies. We excavate to a compacted base below frost depth and build a weep-and-drainage channel behind every retaining wall, so the hydrostatic pressure of a New England winter never gets the leverage to push it out of plumb.

Turn a sloped Durham lot into level, planted, usable ground and — built this way — it stays that way, quietly, for decades.

Durham sits in Strafford County, and most weeks we are somewhere in this pocket of NH Seacoast — which means shorter travel, faster site visits, and a crew that already knows how ground behaves around here.

Freestanding fieldstone is the older language of NH Seacoast, and it is what makes new work read as though it belongs. We source local stone, sort it by hand on site, and dry-stack so each stone carries load to the ones below it — no mortar hiding a mistake. The result carries the settled, irregular character of the walls already standing around Durham Village, Oyster River, and Durham Point.

Where the colonial antiques and well-kept university-town houses call for a cleaner line — a granite-capped seat wall, a mortared wall against a foundation — we build that too, matched to the house and the planting plan.

Price in Durham is driven less by the stone than by what is under it. Access, how far material has to be carried, the depth of base marine clay and glacial till demands, and the amount of drainage a site needs move a number far more than the choice between one bluestone and another.

You get an itemized scope after we walk the property — what is included, what is not, and where the money actually goes. No allowances that quietly become change orders halfway through.

A large share of our New Hampshire work is executing drawings for landscape architects — reading elevations, holding the specified batter and joint, and flagging a conflict before it becomes a change order. Much of it in ongoing collaboration with Jonathan Keep Landscape Design.
