About Lorton Stone, LLC
Lorton Stone, LLC, a minority-owned and woman-owned small business based in Springfield, Virginia, provides stone contracting, masonry restoration, and architectural stone fabrication services to federal agencies as a prime contractor (89% of recent awards). The company operates as a limited liability company specializing in cut stone and stone product manufacturing (NAICS 327991), commercial and institutional building construction, and masonry contracting work.
Lorton Stone's customer base concentrates on federal cultural and infrastructure preservation agencies. The top five customers by award count and dollar value account for 89% of recent awards. The National Gallery of Art anchors the portfolio by dollar magnitude with 7 awards worth $4.1 million in combined potential value, while the Smithsonian Institution also places 7 awards but with a combined potential value of $132 thousand. The Department of the Interior's Departmental Offices (Office of Policy Management and Budget) has issued 4 awards totaling $479 thousand, the Department of the Air Force has placed 4 awards totaling $304 thousand, and the National Park Service National Office has issued 3 awards totaling $253 thousand. The portfolio also includes work for the Smithsonian Institution and smaller awards from the National Park Service and Air Force.
Recent prime work illustrates the company's capability scope. In June 2026, the Department of the Interior (Office of Policy Management and Budget) awarded Lorton Stone a $425 thousand Total Small Business set-aside purchase order for south facade cleaning of the Udall Building in Washington, DC, with completion due July 1, 2026. In September 2025, the National Park Service awarded a $35.4 thousand Total Small Business set-aside for fabricating a replacement granite base (64" x 18" x 64" capstone and dutchman repair piece) for the Albert Pike Memorial statue in cut Sparta Pink Granite. The Air Force awarded a $45 thousand purchase order in September 2025 for fabricating a replacement absolute black granite panel with corrected text. Earlier significant work includes a $213.4 thousand definitive contract from the National Park Service (awarded September 2023) for construction repair of the Arlington Memorial Bridge.
Activity has remained modest but steady, with one award in 2022, one in 2023, three in 2024, three in 2025, and four in 2026 year-to-date. The combined potential value across all 28 awards in the source dataset is $5.3 million, with $3.8 million (72%) obligated. No recompete cliff data is present in the source; the most recent award carries an ultimate completion date of July 14, 2026.
Lorton Stone operates as a subcontractor on a limited basis. Across three named sub-awards, the company performed water-stain removal and sealing work for the U.S. Tax Court under prime Chimes District of Columbia Inc. (July 2025), exterior door replacements at a bridge facility under Blue Construction Services LLC (September 2024), and external concrete repairs for the Consumer Financial Protection Bureau under DW Solutions, LLC (May 2024). The SCI dataset captures 9 records (2 prime, 7 sub) spanning FY2022–FY2024, with FY2022 showing 6.9 FTEs and FY2024 showing 2.4 FTEs on sub contracts; no SCI-reportable invoicing appears for the prime records in the dataset, indicating the company's prime work falls below the $150 thousand SCI reporting threshold or is captured outside SCI's scope. The vendor competes predominantly under Total Small Business set-asides, though several recent awards (Air Force granite sign, Arlington Memorial Bridge repair) were not set-aside designated.
