What R.J. Grondin & Sons does
R.J. Grondin & Sons is a third-generation, family-owned earth moving and construction company headquartered in Gorham, Maine. Founded in 1959 from a dairy farm operation, the company has operated continuously for more than 65 years and serves commercial developers, government agencies, institutional clients, and individual consumers across Southern and Central Maine. The business operates two distinct revenue streams: project-based construction services spanning commercial site work, heavy highway, institutional facilities, subdivision development, utilities, and wetland mitigation; and aggregate material sales of gravel, stone, sand, landscape materials, salt sand, and recycled materials.
Construction services are delivered using a large, modern fleet of earth moving equipment and are priced per project through direct bidding and contracts. Aggregate materials are sourced from company-owned gravel pits and quarries throughout Southern Maine, providing vertical integration that enables direct sales and delivery to consumer and construction site buyers. Select disclosed enterprise customers include IDEXX for commercial site work and Liberty Shipyard for brownfields environmental remediation; an additional site work engagement at 45 Industrial Parkway Drive and an active hotel project in Scarborough are publicly showcased.
The go-to-market motion is direct-to-customer across both revenue streams, with project bidding serving enterprise and institutional clients and direct sales with delivery serving aggregate buyers. Marketing is concentrated on the company website and an active Instagram presence; there is no evidence of paid acquisition, distribution partnerships, or institutional investment. The company employs 101-250 people and is privately held by the founding family, with no funding rounds, M&A activity, or public market exposure disclosed.
