Edgar Alvarado — Founder & Master Mason

The Man Behind the Masonry

Edgar Alvarado was not handed this craft. He built it stone by stone, project by project, across more than three decades of hands-on field work across the Washington metropolitan region.

Born with a natural eye for structure and proportion, Edgar developed his masonry expertise through real construction not classrooms. Every technique he uses was proven through decades of field execution, crew leadership, and the uncompromising standard he holds on every single jobsite.

Today Edgar personally directs every project Edgar Stone Masonry LLC undertakes. He is not a distant owner who signs contracts and disappears. He shows up. He evaluates 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 entire DMV region trust Edgar Stone Masonry LLC with their most valuable investment their home.
