Your Trusted Local Windsor Plumbers

ClearLine Plumbing was founded on a simple principle: people deserve honest, high-quality plumbing service without the hassle or hidden fees often found with big corporations. Our journey began with the realization that what homeowners needed most was a reliable partner—a plumber who treated their property with the same care and respect they would their own. We deliberately built our business to focus on the residential homeowner in the Windsor and greater Sonoma County area. This local focus allows us to respond quickly, understand the specific plumbing challenges of homes in this region, and maintain a commitment to meticulous craftsmanship on every job. For us, plumbing isn't just a trade; it's a commitment to our community, ensuring every repair, installation, and upgrade is done cleanly, efficiently, and with total price clarity from the moment we start to the moment we finish.

Robert initially built his plumbing company on hard work, trust, and clean craftsmanship. After a decade successfully serving the field, he took a pause, sold the business, and spent a year traveling the U.S. with his family.

He returned to Sonoma County following the Tubbs Fire, gaining a new, invaluable perspective while helping to rebuild. Working shoulder-to-shoulder with his father’s elite firm—a company known for multi-million dollar homes with no room for shortcuts—Robert honed his attention to detail and learned what it takes to deliver truly elite work. This experience led him to earn his General B Contractor's license, learning how the entire structure fits together, not just the systems within it.

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