Stone masonry in Washington, D.C.

From a stream-fed koi garden in Chevy Chase to front steps and retaining walls on older city homes — District stonework lives inside tight lots, old foundations and city rules. We plan for all three before a stone is ordered.

The local standard

City stonework has rules.

Trees. In the District, a tree measuring 44 to 99.9 inches around is a Special Tree and needs a permit to remove; a Heritage Tree, 100 inches and up, generally cannot be removed unless it is hazardous. If a patio or slab is planned near a large tree, we check its size before anything else.

Older walls, older problems. Much of our District work is restoration — leaning retaining walls, failing front steps, entries on homes built long before modern bases. A wall usually leans because of water pressure behind it, not the stone; so we rebuild on a proper footing with drainage, and the wall stays put.

How it’s built

The part you never see is the part that lasts.

01

Excavate & reinforce

We dig to solid ground and build a reinforced, drained base.

02

Cut & shape

Each stone is measured and cut on the wet saw to its exact place.

03

Wet-set

Every stone is bedded in mortar, not sand — hand-fit and leveled.

04

Cap & level

Caps and edges set true by hand — the finish that locks it together.

05

Stand behind it

A clean site, an honest timeline, and a five-year warranty in writing — ten years on the base.

Questions from District homeowners

Before you commission.

Do I need a permit to remove a tree for a patio in DC?

If the tree measures 44 inches or more around, yes — it is a Special Tree. At 100 inches and up it is a Heritage Tree and generally cannot be removed. We measure on the site visit so there are no surprises.

Can you repair a leaning retaining wall?

Usually the right answer is to rebuild that section on a proper footing with drainage behind it. Patching the face of a wall that is being pushed by water only buys a season.

Do you work on tight city lots?

Yes. Many District jobs have no room for machines; we stage carefully, protect the property and neighbors, and carry stone in where we have to.

We also work in Georgetown, Capitol Hill, Chevy Chase, Dupont Circle and Northwest D.C. — and across D.C., Maryland and Northern Virginia. See our work in McLean · Potomac · Falls Church · Arlington
