House Bros. Construction Inc.

House Bros. Construction Inc., a self-certified small disadvantaged business based in McCleary, Washington, provides on-site septic system installation and wastewater infrastructure construction to the federal government exclusively as a prime contractor under Total Small Business set-asides. The company is a Subchapter S corporation competing entirely within small-business carve-outs; all twenty-six prime awards in the source footprint carry Total Small Business set-aside designations, with no subcontract or team arrangements present.

House Bros. Construction's customer concentration is extreme: the Department of Health and Human Services Indian Health Service funds 96% of awards (24 awards, $903 thousand combined potential value), with a single Department of Agriculture Forest Service award ($4 thousand) accounting for the remaining 4%. The IHS work is classified predominantly under NAICS 237110 (Water and Sewer Line and Related Structures Construction), with secondary PSC codes reflecting sewage facility and residential building construction. Representative IHS prime work includes a $32,360 firm-fixed-price purchase order (October 2024) for subsurface drip system drainfield installation on Squaxin Island tribal land; a $20,425 purchase order (February 2026) for complete wastewater infrastructure replacement in Mason County serving Skokomish tribal lands, including septic tanks, effluent transport, and drainfield; and a $26,950 purchase order (May 2026) for on-site sewage system replacement at Port Hadlock-Irondale, with completion due July 15, 2026. House Bros. Construction sits on a single blanket purchase agreement (HHS IHS 248201100029B) generating 17 task orders worth $265 thousand in combined potential value.

Activity is intermittent: two awards in 2017, five in 2018, one in 2021, three in 2024, and two in 2026. Combined potential value across all awards is $906 thousand, with $406 thousand (45%) obligated to date. The vendor's contract history, spanning from 2004, demonstrates consistent engagement with IHS on rural and tribal infrastructure projects throughout Washington state, with individual purchase orders ranging from $4 thousand to $32,360.
