What M & J Underground, Inc. does
M & J Underground, Inc. is a family-owned, full-union underground utility contractor founded in 1990 by Jan Reading and headquartered in Monee, Illinois. The company provides a comprehensive suite of site utility and underground construction services spanning twelve core offerings: hydro-excavation, licensed septic installation and repair, concrete contracting, asphalt/paving, sanitary sewer installation and repair, sewer cleaning and jetting, directional drilling, general excavation, storm sewer installation and repair, water main installation and repair, waterline installation and repair, and after-hours emergency utility services. Service capability is supported by IDPH plumbing and septic licenses and an equipment fleet capable of trenchless and open-cut methods.
The company operates on a project-based, direct-to-consumer and direct-to-government business model, with no intermediaries or resellers. Customers initiate engagement via phone (708-534-6434) or a website estimate request form, with quotes returned within 24–48 hours. Pricing is custom per project and not publicly disclosed; a complete satisfaction guarantee is offered. The company generates revenue from three primary customer segments: government/municipal (its primary vertical, including US Army Corps of Engineers, Illinois DOT, and multiple villages), commercial/retail (e.g., 7-Eleven, Popeye's), and residential homeowners in the Chicago South Suburbs.
M & J Underground's competitive positioning is anchored in its certified woman-owned minority business enterprise (MBE/DBE) status across IDOT, City of Chicago, Illinois CMS, CBGD, and SBA, which gives it a structural advantage in bidding on state and federally funded projects. It is a full union shop affiliated with International Union of Operating Engineers Local 150 and Construction & General Laborers' District Council Local 5, and holds a BBB A+ Accredited Business rating. Geographic reach is concentrated in Chicago's South Suburbs (Monee, Peotone, Manteno, Lockport, New Lenox, Plainfield, Richton Park, Country Club Hills, Park Forest, Beecher, Posen, Sauk Village, Crete, Tinley Park, Lansing, Hinsdale), with no public evidence of operations outside Illinois. The company maintains minimal digital infrastructure and relies primarily on direct contact, its website, and BBB accreditation for customer acquisition. No M&A, funding rounds, or corporate restructuring events are disclosed.
