Our Company

Our strength is in our ability to innovate, integrate and execute complex building projects.

Helmer & Sons, Inc. is a family-owned construction company established in 1975 and located in the Napa Valley of Northern California. We build projects for a wide variety of clients in Napa, Sonoma, Solano, Lake, and Mendocino Counties.

Our company has completed projects large and small for clients ranging from public agencies and institutions to developers, general contractors, small businesses, and homeowners. Helmer & Sons is licensed as both a general building and engineering contractor, offering complete construction services in building construction and sitework (including underground work, grading, and paving).

In each area, we’re committed to finding solutions for our clients — solutions that facilitate effective projects and save money, improve efficiencies, and accelerate project completion dates. These solutions maximize our clients’ return and minimize their risk. We recognize that each project is different and each client has unique priorities! We work hard at collaborating with our clients so they fully understand their options and the cost and value of those options.
