Harmonbk LLC

Harmonbk LLC, a woman-owned small business based in Orange Park, Florida, delivers janitorial and facility support services to civilian federal agencies and the Department of the Army as a prime contractor exclusively—all seven recent awards are prime contracts. Harmonbk holds SBA certifications as an Economically Disadvantaged Women-Owned Small Business (EDWOSB) and Women-Owned Small Business (WOSB), and is structured as a limited liability company. The vendor competes under total small business set-asides in five of seven recent awards; two purchases by the International Boundary and Water Commission carried no set-aside designation but leveraged the company's EDWOSB and WOSB certifications in full-and-open competition.

Harmonbk's capability portfolio centers on janitorial and custodial services (five awards under NAICS 561720, PSC S201) and portable toilet rental, servicing, and waste removal (two awards under NAICS 562910). Representative work includes a $91,973.38 Total Small Business purchase order with the Army Reserve Command for custodial services at Machesney Park, Illinois, running through March 2031 with four twelve-month option periods; a $78,733.81 Total Small Business contract with the Army Corps of Engineers Philadelphia District for portable toilet services at Blue Marsh Lake, Pennsylvania, through December 2028; and a $44,075.40 firm fixed-price janitorial contract with the International Boundary and Water Commission for the Falcon Power Plant in Falcon Heights, Texas, through March 2031, covering approximately 3,500 square feet cleaned twice weekly.

Customer concentration is broad and shallow. The top five agencies account for 86% of awards by count and 96% of combined potential value, led by the Department of the Army Reserve Command ($92 thousand) and the Army Corps of Engineers ($79 thousand), followed by the International Boundary and Water Commission (two awards, $74 thousand combined), the California Army National Guard ($41 thousand), and the Department of the Interior National Park Service ($41 thousand). No single agency dominates; the vendor operates across six distinct customer agencies with purchase-order relationships rather than vehicle seats or IDIQs.

Activity has accelerated recently—one award in 2022, one in 2023, one in 2025, and four in 2026—but remains modest in volume and dollar magnitude. Combined potential value across all seven awards is $340 thousand, with $122 thousand obligated (36% of ceiling). The vendor holds no parent vehicles, BPAs, or GWACs. Five awards with ultimate completion dates through March 2031 represent recompete risk or opportunity within the next twenty-four to thirty-six months. Harmonbk has no subcontract footprint in the source data; all work is prime-performed.
