About the company
Lorton Stone, LLC, a minority-owned and woman-owned small business based in Springfield, Virginia, delivers stone contracting, masonry restoration, and historic preservation services to federal agencies as a prime contractor (87% of recent awards), competing predominantly under Total Small Business set-asides on purchase orders and definitive contracts. The company specializes in concrete work: granite and stone fabrication, monument and memorial restoration, historic masonry repair, facade cleaning, and structural stone replacement at federal buildings and cultural institutions in Washington, DC and surrounding areas.
Lorton Stone's customer base concentrates heavily on cultural and federal facility stewardship agencies. The top five funding agencies account for 87% of recent awards, led by the National Gallery of Art (7 awards, $4.1 million combined potential value) and the Department of the Interior's Office of Policy Management and Budget (5 awards, $1.1 million), followed by the Department of the Air Force (4 awards, $304 thousand), the National Park Service (3 awards, $253 thousand), and the Smithsonian Institution (8 awards, $178 thousand). The rankings diverge meaningfully — National Gallery anchors the dollars despite placing fewer awards than Smithsonian, signaling larger contract values per award — but both reflect the same mission set: federal building and monument preservation. Recent work includes a $589,007 Total Small Business purchase order from Interior's Office of Policy Management and Budget for historic cobblestone ramp repair at the Stewart Lee Udall Building (awarded September 2026, performance through September 2027), a $425,000 order for Udall Building south facade cleaning (June 2026), a $35,396 National Park Service order for fabricating a replacement granite base for the Albert Pike Memorial statue (September 2025), and a $213,400 definitive contract for Arlington Memorial Bridge construction repair (September 2023). The company's NAICS footprint splits evenly between Cut Stone and Stone Product Manufacturing (NAICS 327991) and Masonry Contractors (NAICS 238140), with ancillary Commercial and Institutional Building Construction work.
Activity has grown incrementally — one award in 2022 and 2023, three in 2024, four in 2025, and six in 2026 — but remains concentrated and small relative to the broader federal contracting market. Only one award (the $589,007 cobblestone ramp repair) faces ultimate completion within the next twenty-four months, limiting near-term recompete exposure. Across the sub-award portfolio, Lorton Stone performs masonry and concrete repairs as a subcontractor to general contractors and design-build primes: water stain removal at the Tax Court Great Hall under Chimes District Of Columbia Inc. (July 2025), replacement granite column base sills for Harry S. Truman Building garage leak repairs under DW Solutions, LLC (April 2025), exterior door replacements under Blue Construction Services LLC (September 2024), and concrete repairs at the Consumer Financial Protection Bureau building under DW Solutions, LLC (May 2024). Service Contract Inventory data shows minimal SCI-reportable invoicing and is not representative of the company's actual federal services volume — the data reflects only two SCI prime records across FY2022–FY2025, with the vendor's substantive work appearing primarily as purchase orders outside the SCI threshold or as subcontractor support.
