What R&J Construction Inc does

R&J Construction, Inc. is a privately held, full-service custom building company incorporated in 1986 and headquartered in Danville, California. The firm delivers ground-up custom homes, major remodels, additions, outdoor living spaces, historic renovations, and ADA upgrades for high-end residential property owners, alongside commercial tenant improvements, office, retail, and restaurant construction for businesses across the Mt Diablo Region of the San Francisco East Bay (Alamo, Blackhawk, Danville, Diablo, Lafayette, Livermore, Moraga, Orinda, Pleasanton, San Ramon, and Walnut Creek). The company runs as a founder-controlled operation led by co-founders Jim Wood (President, 45+ years of experience) and Ron Longchamps (Vice President, 53 years), with the next generation already in key roles (Jesse Longchamps, Estimator/Sales since 2019; Eric Wood, Superintendent since 2018), and a supervisory bench of 6-7 superintendents whose tenure at R&J ranges from 1992 to 2021.

The business model is project-based, quote-driven custom construction with most projects starting around $200,000 and pricing determined by scope, finishes, and complexity after a feasibility study and value engineering exercise. Revenue is generated from three streams: custom residential construction, custom commercial construction, and pre-construction services (feasibility studies, site evaluations, value engineering, and construction budgeting). Go-to-market is direct-to-customer engagement with no intermediaries or distribution partners, relying on word-of-mouth and a recurring-client base (more than half of projects originate from repeat clients) supplemented by an extensive named-project portfolio on the company website.

R&J's technical stack consists of internal construction management systems plus a proprietary job bidding software created by Jim Wood to produce accurate, detailed proposals, along with CADD drawing capability. There is no indication of AI/ML systems, external APIs, or platform integrations. The firm does not use third-party distribution or channel partners; all work is self-performed core-skill execution (estimating, project management, field supervision, QA/QC) augmented by subcontracted trades. Pricing and project specifications are not publicly disclosed; engagements are customized per client.
