Robert Henningsen

Robert built his first plumbing company on hard work, trust, and clean craftsmanship — but after a decade in the field, he decided to press pause. He sold the business, bought an RV, and took the family on a year-long road trip across the U.S. Six months in, the Tubbs Fire devastated Sonoma County. Robert returned home to help — not just anyone, but his father, a seasoned general contractor known for building high-end custom estates throughout Wine Country.

Working shoulder to shoulder with his father’s firm — a company renowned for multi-million dollar homes with no room for shortcuts — Robert gained a new perspective on construction, attention to detail, and what it takes to deliver truly elite work. It took another four years to earn his General B contractors license while learning how the whole structure fits together — not just the systems inside it.

Eventually, he came full circle. With more experience, broader skills, and a deeper respect for the trade, Robert founded ClearLine Plumbing — a family-run business dedicated to clean work, clear prices, and no surprises. Today, he works alongside his son, bringing high-level service with a neighborly touch to homeowners, property managers, and remodelers across Sonoma County.
