About Petersen Plumbing Services
Petersen Plumbing Services has served Marin and Sonoma counties since 2008, earning a 4.6-star rating across 66 reviews. Based in Mill Valley at 751 E Blithedale Ave, the company holds license #932251 and maintains 24-hour availability every day of the week. Technicians service residential and commercial properties across 13 Marin County communities including Corte Madera, Fairfax, San Rafael, and Sausalito, plus nine Sonoma County locations from Sebastopol to Santa Rosa. The business offers full-spectrum plumbing services ranging from emergency repairs and water heater installation to new construction plumbing design and commercial system maintenance.
What distinguishes Petersen Plumbing is their commitment to transparency and precision. The company advertises a $189 call fee that credits toward the final bill, giving homeowners cost clarity before work begins. Their four-pillar approach emphasizes reliability, integrity, urgency, and attention to detail. Reviewers consistently note technicians take time to explain issues in understandable terms rather than using jargon, and the team leaves job sites clean. Beyond standard plumbing, they handle fire safety system installations, complex remodels, and provide consulting services for challenging plumbing challenges.
Customer reviews highlight specific scenarios that demonstrate their approach. One reviewer described Taylor diagnosing a tankless water heater issue, providing excellent advice and completing work promptly. Another mentioned Kyle re-routing a gas line for a new cooktop, finishing the job in a few hours after providing a firm quote. Multiple reviewers emphasize the technicians treat customers with respect, explain things without making them feel ignorant, and take pride in their work. A reviewer noted their water heater installed years ago continues performing well thanks to annual service visits.
