Benjamin Franklin Plumbing provides trusted residential plumbing services and repairs throughout the Greater Bay Area. From fixing drains, sinks, toilets, disposals and other household plumbing systems to cleaning sewers, maintaining water heaters (including tankless) and repiping water delivery lines, the company offers comprehensive plumbing solutions backed by years of experience.

Owner Forrest Gagne represents the second generation of family leadership in the business, following in the footsteps of his father, Daniel Gagne. Daniel began his plumbing career at 18 and founded his own company in 1995 alongside his brother, Patrick. After several years specializing in new construction and remodeling, the brothers joined the Benjamin Franklin Plumbing franchise network in 2001. In early 2025, David Langdale took over day-to-day operations of Benjamin Franklin Plumbing, continuing its long-standing tradition of customer-focused, locally managed service. Under his leadership, the company remains independently operated while proudly representing the national Authority Brands family.

Benjamin Franklin Plumbing stands by its signature “If there’s any delay, it’s you we pay!” guarantee, promising customers $5 for every minute a technician arrives past the scheduled time (up to $300). All technicians undergo extensive in-house training to stay current with the latest plumbing technologies, installation methods and repair practices.
