Mayointhemix LLC

Mayointhemix LLC, doing business as Mayo Elite Solutions, is a minority-owned, self-certified small disadvantaged business based in Upper Marlboro, Maryland, that operates as a prime contractor delivering facilities maintenance, HVAC installation and repair, infrastructure construction, and equipment procurement to federal civilian and defense agencies exclusively under total small business set-asides. The vendor competes uniformly in the small-business-reserved space — all 29 prime awards in the portfolio carry either total small business or partial small business set-aside designations, with the exception of two full-and-open procurements (a galley vent cleaning order from the Coast Guard and an autoclave purchase for EPA Region 9).

Mayo Elite Solutions' capability footprint centers on facilities trades and equipment services. Representative work includes a $44.4 million heating and cooling system installation at Dale Hollow National Fish Hatchery in Tennessee for the U.S. Fish and Wildlife Service (awarded February 2025), a $38.4 million rolling door replacement at the National Weather Service Forecast Office in Caribou, Maine for NOAA (September 2025), a $35 thousand grease trap cleaning contract at Scott Air Force Base in Illinois for Air Mobility Command with a completion date extending to September 2029 (October 2024), HVAC system replacements across the Department of the Interior at multiple locations including the Apple Valley Fire Center in California, roof and structural repairs for the U.S. Army Corps of Engineers including the Allegheny River Lock 4 project in Pennsylvania, and emergency bridge repairs for the Forest Service on the Cloquet River in Minnesota. The vendor also executes smaller equipment procurements and specialized services — a $52 thousand order for 109 all-terrain utility task vehicles for the Air National Guard, a $34.8 thousand conference room table for U.S. Army Recruiting Command, and steel crossarms for the Western Area Power Administration's Rapid City infrastructure project.

Customer concentration is diffuse across 21 distinct federal agencies. The top five customers account for 45% of award count and 49% of potential value, led by the Department of Energy's Western Area Power Administration (four awards, $108 thousand combined value), the Department of Homeland Security's U.S. Coast Guard (three awards, $91 thousand), the Department of the Interior's Bureau of Land Management California Region (two awards, $66 thousand), the Department of the Air Force's Air Education and Training Command (one award, $65 thousand), and the U.S. Army Corps of Engineers (two awards, $65 thousand). No single customer dominates the portfolio; work distributes across regional offices and installations of civilian natural-resource and infrastructure agencies (Forest Service, Fish and Wildlife Service, Bureau of Land Management, Park Service), energy infrastructure (WAPA), maritime operations (Coast Guard), and scattered Army and Air Force installations.

The vendor operates solely as a prime contractor — zero sub-award activity appears in the source. Activity has grown from nine awards in 2024 to eighteen in 2025, with two awards recorded in the first quarter of 2026. Combined potential value across the 29-award portfolio is $799 thousand, with $714 thousand obligated (89% coverage). Eleven awards have ultimate completion dates falling between now and mid-2029, anchored by the $65 thousand boiler rental contract at Maxwell Air Force Base extending to June 2025 and the $40.9 thousand elevator maintenance and inspection contract with the Army Corps of Engineers running through August 2029. The vendor's primary NAICS footprint skews toward plumbing, heating, and air-conditioning contractors (four awards) and HVAC equipment manufacturing or installation (three awards), with secondary work in highway and bridge construction, roofing, and equipment procurement. All contracts are firm-fixed-price purchase orders or definitive contracts with short performance periods (most between 30 and 90 days), typical of facilities and equipment services in the small-business reserve.
