The Standard

A patio is only as good as the base no one ever sees.

We don't pour shortcuts. Every project begins below the surface — reinforced footings, engineered drainage, and a compacted base built to hold for decades. What you see is hand-laid natural stone. What lasts is the discipline underneath it.

The Man Behind the Masonry

He didn't inherit the craft.
He built it, stone by stone.

For more than 36 years, Edgar Alvarado has worked the stone of the Washington region by hand — no classrooms, no shortcuts. Every technique he uses was proven on real jobsites, under real load, through decades of field leadership.

He is not a distant owner who signs a contract and disappears. He shows up. He reads the site. He sets the standard — and he does not leave until the work is right. That is why homeowners across Potomac, McLean, Bethesda, Georgetown, and the wider DMV trust him with their most valuable investment: their home.

Our Standard

Integrity over shortcuts. Precision over speed. Stonework that performs for decades, elevates the home, and carries the legacy of true masonry leadership.

Selected Work

A portfolio set in stone.

Natural flagstone, bluestone, fieldstone, and cobble — laid across estates throughout the Washington metropolitan region.

What We Build

From terrace to chimney.

Natural stone is our craft — the heavy, structural work our name is built on. Every surface is engineered from the base up, never simply placed.

01

Flagstone & Bluestone Patios

Hand-laid natural stone terraces, courtyards, and entertaining spaces.

02

Retaining & Seat Walls

Natural stone and boulder walls — structural, sculptural, and built to hold.

03

Stone Veneer & Structural Masonry

Full-height chimneys, columns, and load-bearing stone facades.

04

Cobblestone & Premium Driveways

Belgian cobble borders and premium paver fields set on engineered, reinforced bases.

05

Walkways, Steps & Stoops

Curved stone steps and walkways that move through a landscape with intent.

Natural stone, fieldstone, flagstone, and bluestone — chosen for durability, structural strength, and refined appearance. No low-grade substitutes.

Below grade

Precision from the ground up

Excavation, drainage, compaction, and footings done correctly before a single stone is set — so the work stays true for decades.

Design Partners

We build what your designer draws.

A designer does not keep a mason on staff. They find one — and for over three decades, the region's leading designers and landscape architects have brought their drawings to Edgar. A plan is only as good as the hands that set it. We don't redraw the vision. We build it.

01

Built to the drawing

We read plans and hold detail. Elevations, joints, radii, coursing — set as specified, not as convenient.

02

Quiet on the property

Clean staging, protected grounds, and a crew that respects the household and the wider project schedule.

03

One trade, mastered

We don't sell design. We set stone — and we have done nothing else for over thirty-six years.

We have been the hands behind this region's finest designed landscapes for over thirty years. Architects, landscape designers and builders: we accept a limited number of collaborations each season.
