Serving Marin County Since 1989 — Now Proudly in Sonoma
From everyday repairs to major sewer line projects, our licensed team delivers top-quality residential and commercial plumbing across Marin and Sonoma Counties — backed by decades of hands-on experience, a strong local reputation, and a proven track record of customer satisfaction.
Being Diamond Certified means we’ve passed one of the most rigorous vetting processes in the industry — and we do it every year. To qualify, companies must score 90 or higher out of 100 in independent customer satisfaction surveys conducted by a third-party research firm. On top of that, Diamond Certified companies must pass licensing, insurance, and credential checks, and they’re monitored continually to ensure standards stay high.
At Mike Testa Plumbing, this certification shows we’re not just promising quality — we’re proving it. Our customer satisfaction is verified annually, and our work is backed by the Diamond Certified Performance Guarantee, offering you extra peace of mind when choosing a plumber. Fewer than 20% of companies that apply actually earn this honor — and we’re proud to be one of them.
