About the company
Mayointhemix LLC, doing business as Mayo Elite Solutions, is a minority-owned, self-certified small disadvantaged business providing facilities maintenance, HVAC systems, infrastructure repair, and equipment procurement services to federal agencies exclusively as a prime contractor on total small business set-asides. The Upper Marlboro, Maryland-based company competes entirely within set-aside carve-outs—all 37 recent prime awards carry total small business designations or partial small business set-asides—with no presence on full-and-open or parent contract vehicles.
Customer concentration is highly fragmented across 24 federal agencies, reflecting a transactional, scattered award pattern. The top three funding sources by potential value account for 66 percent of combined value: the Department of Homeland Security's U.S. Coast Guard ($398 thousand across 4 awards), the Department of the Air Force's Air Education and Training Command ($247 thousand across 2 awards), and a single $240 thousand Department of Agriculture Forest Service contract for greenhouse refurbishment at the USDA-ARS Center for Medical, Agricultural, and Veterinary Entomology in Gainesville, Florida. The Department of Energy's Western Area Power Administration, while leading in award count (6 awards), contributes only $185 thousand in potential value, indicating small individual task values. No customer relationship appears to anchor more than six awards or exceed $400 thousand in combined potential value.
Capability portfolio clusters around HVAC systems, building envelope repair, and site infrastructure. Representative prime work includes a $240 thousand definitive contract with USDA Forest Service for greenhouse refurbishment with 120-calendar-day performance ending January 31, 2027; a $181 thousand purchase order from Air Education and Training Command for golf cart bridge removal and replacement at JBSA Lackland with completion by November 7, 2026; a $198 thousand grease-trap cleaning service contract with Air Mobility Command at Scott Air Force Base running through September 30, 2029; a $307 thousand purchase order from the U.S. Coast Guard for bullet-trap cleaning and debris removal at the Dexter Small Arms Firing Range in Honolulu with completion by August 31, 2030; and multiple HVAC system replacements ranging from $13 thousand to $65 thousand at facilities across the Interior Department's Bureau of Land Management, Fish and Wildlife Service, and Army Corps of Engineers. Work spans NAICS codes centered on plumbing, heating, and air-conditioning contractors (4 awards), HVAC equipment manufacturing (3 awards), and specialty trade contracting. Awards carry firm-fixed-price terms with performance periods ranging from 10 calendar days (Coast Guard gravel pad at Weslaco, Texas, December 1, 2025) to multi-year service contracts (elevator maintenance through August 6, 2029; grease-trap cleaning through September 30, 2029).
Activity has grown year over year—9 awards in 2024, 18 in 2025, 10 year-to-date in 2026—driven primarily by small-value transactional awards. Combined potential value across all 37 awards stands at $1.7 million, with $1.4 million obligated (82 percent). Five awards (combined potential value $552 thousand) reach ultimate completion within the next twenty-four months and face recompete. Mayo Elite Solutions maintains no subcontractor relationships and carries no presence on government-wide IDIQs, GWACs, or agency-wide BPAs; all work is direct prime awards. The vendor's federal footprint is entirely facilities, infrastructure, and equipment-services-oriented, with no IT, professional services, or management consulting exposure. Customer agencies span civilian (USDA, Interior, Commerce, EPA, NOAA) and defense (Air Force, Army, Coast Guard) sectors, but with no concentration sufficient to create strategic account dependency or insider-threat positioning.
