Sentinel Services, LLC

Sentinel Services, LLC, a service-disabled veteran-owned small business (SDVOSB) based in Elkins, Arkansas, provides facilities maintenance, repair, and equipment replacement services to the Department of Veterans Affairs as a prime contractor across 56 awards with a combined potential value of $24.4 million, competing predominantly under SDVOSB set-asides and full-and-open procurements.

Sentinel Services is a for-profit limited liability company and veteran-owned business with a named subsidiary, Sentinel-Sobroco JV, LLC, also structured as a service-disabled veteran-owned small business joint venture. The vendor operates across primary NAICS categories centered on plumbing, heating, and air-conditioning contractors (14 awards) and water supply and irrigation systems (6 awards), with PSC codes reflecting maintenance and repair of HVAC equipment (7 awards), plumbing and heating equipment (9 awards), and materials handling equipment (2 awards). Sentinel Services holds a GSA Federal Supply Schedule contract with a $1 million ceiling and nine labor categories priced from $54.81 per hour for general laborers through $104.92 per hour for project managers, all at high school education with no security-clearance requirements.

Customer concentration is extreme and singular. The Department of Veterans Affairs Veterans Integrated Service Network 16 (VISN 16) accounts for 40 of 56 awards (71%) and $12.7 million of combined potential value (52%), followed distantly by VISN 17 (8 awards, $5.8 million) and VISN 19 (2 awards, $3.4 million). These three VA networks represent 50 of 56 awards (89%) and $21.9 million (90%) of total potential value. Sentinel has worked with nine distinct customer agencies in total, but nine of ten dollars flow to Veterans Affairs.

Recent award activity has grown sharply — two awards in 2021, none in 2022, fourteen in 2023, five in 2024, thirteen in 2025, and twenty-two in 2026 year-to-date. Representative work illustrates the scope: a $2.69 million SDVOSB set-aside purchase order from VISN 17 (awarded June 30, 2026) for sterile processing service water system testing, maintenance, and repair at the VA Medical Center in San Antonio, Texas, with compliance required to ANSI/AAMI ST108:2023 standard and running through June 29, 2031; a $3.08 million SDVOSB set-aside purchase order from VISN 19 (awarded August 22, 2025) for floor restoration services at the Rocky Mountain Regional VA Medical Center in Aurora, Colorado, covering approximately 60,644 square feet of hard-surface flooring with a five-year warranty through August 21, 2030; and a $2.59 million SDVOSB set-aside purchase order from VISN 16 (awarded October 1, 2025) for annual and semi-annual boiler and steamer testing and inspection services in Fayetteville, Arkansas through September 30, 2030. Smaller awards include a $558 thousand SDVOSB set-aside for fire and smoke door inspection and repair services at Veterans Health Care System of the Ozarks (awarded March 6, 2026, running through September 30, 2027 with four optional twelve-month extensions), and a $1.58 million SDVOSB set-aside for facilities maintenance, janitorial, and landscaping services at Fort Johnson Community Based Outpatient Clinic in Leesville, Louisiana (awarded September 30, 2025, extending through September 20, 2030).

Sentinel holds four active indefinite-delivery contracts anchoring its VA footprint. A single-award SDVOSB IDIQ with VISN 16 (awarded February 14, 2025, valued at $749 thousand, extending through February 13, 2029) covers HVAC maintenance, repair, and equipment replacement; two delivery orders have been issued against it ($630 thousand and $160 thousand, both for HVAC maintenance at Elkins, Arkansas). A second single-award SDVOSB IDIQ with VISN 16 (awarded July 15, 2026, $850 thousand, running through July 14, 2031) procures comprehensive fire alarm services and inspections under PSC J042 and NAICS 561790, with one delivery order issued ($124 thousand, Fayetteville, Arkansas, July 14, 2027 completion). A third single-award IDIQ with VISN 16 (awarded September 15, 2026, $348 thousand, through September 14, 2031) covers water storage tank inspections and maintenance under Executive Order 14398 at Alexandria, Louisiana, with one delivery order issued ($165 thousand). The GSA Federal Supply Schedule (awarded January 23, 2026, $1 million ceiling through January 22, 2031) enables nationwide ordering across the nine labor categories.

Eight recompete events mature within the next twenty-four months, carrying combined potential value of $3.7 million, representing 15% of the current active portfolio. Service Contract Inventory data shows minimal SCI-reportable invoicing: $416 thousand across fiscal year 2024 under a single prime contract representing 0.9 FTEs, with a derived hourly rate of $224.51 per hour; no SCI invoicing is recorded in fiscal years 2023 or 2025. This sparse SCI footprint reflects the vendor's reliance on smaller purchase orders and task orders under existing indefinite-delivery vehicles rather than large bundled service contracts. Sentinel is a pure prime contractor — 100% of 56 awards are prime, with zero subcontract engagements in the source data, and the vendor carries no named subcontractors across its portfolio. The company structures nearly all work as direct delivery from its own labor force, with no leveraging of secondary supply chains or teaming arrangements in the federal footprint captured by this source.
