Top 10 Best Plumbers in San Jose, CA | Updated 2026
March 27, 2026
Finding a reliable plumber in San Jose takes more than a quick Google search. The South Bay has dozens of plumbing companies, and they range from family-owned specialists who know every pipe material in a 1950s Willow Glen ranch to national franchises dispatching technicians who may have never worked in your neighborhood before.
This guide covers nine of the most established and well-reviewed plumbing companies serving San Jose and the surrounding South Bay. We evaluated each based on years in business, review profiles across Google, Yelp, and the BBB, service range, local specialization, and what actual customers consistently say about their experience.
Venture Plumbing is our company, and we wrote this guide. We put ourselves at the top because we believe our combination of local expertise, specialized services, and long-term track record in South Bay homes earns that position. But every company on this list is a legitimate, licensed service that serves San Jose homeowners, and we've done our best to represent each one honestly.

Multiple reviewers note their competitive pricing compared to other established San Jose plumbers, and their team is known for showing up on time and providing honest estimates.

They also offer a repeat customer discount, which is a nice touch for homeowners who use a single plumber for all their needs.
5. Knockout Plumbing & Repipe
Headquarters: 191 Dillon Ave, Campbell, CA 95008
Founded: 2022
Phone: (669) 400-9662
Knockout Plumbing & Repipe is a newer company based in Campbell that, as the name suggests, specializes in repiping alongside general plumbing services. Despite being founded in 2022, they have built a solid reputation quickly. They offer copper repipes for residential and multifamily properties and advertise the ability to complete most repipe projects in a single day, which is a strong selling point for homeowners who want minimal disruption.

Reviewers highlight the responsiveness of ownership and the quality of the repiping work specifically.
6. San Jose Plumbing, Inc.
Headquarters: San Jose, CA
Founded: 1991
Phone: (408) 372-8978
San Jose Plumbing is one of the longest-running plumbing companies in the city founded over 30 years ago. Their services include water heater work, sewer lines, drain cleaning, gas lines, and general plumbing repairs. They serve both residential and commercial clients, including restaurants, property management companies, and schools. If you are looking for a plumber with deep roots in San Jose, this is one of the oldest family-run options in the city.
7. Plumbtree Plumbing & Rooter
Headquarters: 210 Paraiso Ct, San Jose, CA 95119
Founded: 2020
Phone: (408) 290-3706
Plumbtree Plumbing & Rooter is a family-owned, San Jose-based company that focuses exclusively on residential plumbing for single-family homes. They intentionally do not take on commercial work, new construction, condos, or apartment complexes, which means their entire team is focused on the kind of homes most San Jose residents actually live in. Their approach emphasizes homeowner education: technicians explain what they find, present options, and let you decide rather than pushing the most expensive repair. They serve San Jose, Campbell, Saratoga, Mountain View, Los Altos, Los Gatos, Milpitas, and Sunnyvale.
8. Handy Plumbing Man
Headquarters: 1011 American St, San Carlos, CA 94070
Founded: 2017
Phone: (650) 727-6377
Handy Plumbing Man is based in San Carlos but serves San Jose and much of the South Bay and Peninsula. They have built one of the strongest review profiles of any plumbing company in the area, with over 1,200 Yelp reviews and a near-perfect rating. They are known for same-day service, flat-rate pricing with no commission-based upselling, and a 100% satisfaction guarantee. They handle drain cleaning, water heater work, sewer line repair and trenchless replacement, fixture installation, and general plumbing. Worth noting that they are based on the Peninsula, so response times to south San Jose may be longer than companies headquartered in the city.
9. Roto-Rooter
Headquarters: 175 Bernal Rd, Ste 100, San Jose, CA 95119
Founded: 1935
Phone: (650) 769-3565
Roto-Rooter is the most recognized plumbing brand in the country, and their San Jose location offers 24/7 emergency service with no extra charge for nights, weekends, or holidays. That availability is their biggest advantage. They provide drain cleaning, water heater service, sewer line work, and water cleanup and restoration services. However, the tradeoff for national brand availability is that you are not always getting a technician who specializes in South Bay homes. Pricing can also vary significantly depending on the technician and the job. For straightforward emergencies where speed matters most, they are a reliable option. For larger planned projects like repipes, water heater upgrades, or sewer replacements, a local specialist is typically a better fit.
10. King Kong Plumbing
Headquarters: 332 Ezie St, San Jose, CA 95111
Founded: 2021
Phone:
(408) 667-4471
King Kong Plumbing is a San Jose-based company that specializes in underground plumbing work, particularly trenchless sewer replacement, sewer line repair, water line replacement, and camera inspections. They also handle general plumbing including water heaters, drain cleaning, fixture installation, and grease trap work. Despite being a relatively young company, they have built a strong review profile on Yelp with 380+ reviews and a near-perfect rating, and their BuildZoom score ranks them in the top 4% of California licensed contractors based on verified permit activity. Reviewers consistently highlight their responsiveness, honest pricing, and willingness to find cost-effective solutions. Multiple customers mention that King Kong identified less expensive approaches to problems that other plumbers had quoted at significantly higher prices.
How We Chose These Companies
Every company on this list meets the following criteria: they are licensed by the California Contractors State License Board, they actively serve San Jose and the surrounding South Bay, and they have a meaningful track record of customer reviews across at least two platforms (Google, Yelp, BBB, HomeAdvisor, or Diamond Certified).
We prioritized companies that are locally owned and operated because local plumbers have direct familiarity with the housing stock, water conditions, and permitting requirements specific to San Jose and Santa Clara County. National franchises are included where they have a significant local presence.
There are other good plumbers in San Jose not listed here, these are the ten we believe offer the strongest combination of experience, service range, and proven customer satisfaction for South Bay homeowners in 2026.
