Asking Price: $2,159,000Established Underground Construction Contractor
Not Disclosed, CA
Sonoma County
Company Overview: This U.S.-based specialty contractor, builds underground spaces for commercial and residential clients across one western state. The company is best known for winery-related caves used for storage, production, and guest experiences. It operates in a niche with few direct competitors and has maintained a long presence supported by referrals and industry relationships.Product & Customer Base: Core services cover design-assist and construction of underground tunnels and chambers for barrel storage, fermentation, labs, and hospitality. The firm also completes related underground work such as soil nail walls, small-bore tunneling through existing structures, elevator shafts, and select civil utility projects. Residential/private caves are a growing segment, with projects ranging from a few hundred to many thousands of square feet and high-end finishes. Commercial winery projects represent the large majority of revenue, with the balance from residential and related underground structures.Operations & Team: Delivery is field-led with multiple long-tenured supervisors and foremen. A senior finisher oversees close-out quality and architectural detail. Technical supervisors plan sequencing, manage safety, and solve site challenges typical of underground work. Architects and consultants interface directly with foremen and superintendents, reflecting strong trust in field expertise. The managing partner supports drawing interpretation, phase planning, estimating, project management, and relationship-based business development. The company holds both general engineering and general building licenses for its state, enabling full build-outs. Each project includes on-site underground safety and gas-testing oversight. The business runs from a leased office, maintains a well-equipped fleet of specialized gear, and carries minimal inventory. Typical cash cycles reflect construction norms, with receivables collected in roughly one to two months.Growth: Demand has been sustained by reputation and repeat referrals from owners and consultants, with a small competitive set and steady bid flow. Margins benefit from specialization and technical know-how, while residential/private caves provide mix diversification. Clear upside exists in formalizing partnerships with outside general contractors; legacy relationships have limited access to some bids, and removing that constraint can expand pipeline. Additional opportunities include targeted marketing beyond word-of-mouth, geographic reach within the licensed state, and further development of architecturally distinctive underground hospitality spaces.Transition: The primary owner is selling to step back after a long career in construction. They are open to a structured handover and can remain in a reduced role focused on marketing, estimating, and project management oversight. The team is stable, and the model supports a strong general manager leading day-to-day operations, enabling a smooth transition for a new owner or strategic acquirer.
