Our Story

Professor Plumb is a specialist residential and commercial plumbing company serving San Francisco and the Greater Bay Area.

Founded in 2003 by San Francisco native Michael Ciofalo, Professor Plumb has built its reputation on thoughtful customer service and high-quality work with a socially conscious edge. We believe that every project should lay the foundation for a lasting relationship. So we take time to craft custom plumbing and heating solutions that not only meet our customers’ expectations, but exceed them whenever possible.

If you are looking for a competent and reliable plumber, look no further. Professor Plumb is one of San Francisco's premier plumbing companies. Professor Plumb offers full-service contracting, design, installation, maintenance and repair of commercial and residential systems. We specialize in boilers and high-efficiency equipment, as well as hydronic, radiant heat and solar-thermal hot water systems.

Our Master and Journeyman plumbers are artisans who understand the unique requirements of San Francisco’s plumbing and heating environments—the hills and valleys, you might say. We can handle any application, from new SOMA highrises to the stately Victorians of the Barbary Coast days. No plumbing job is too big. No plumbing job is too small.
