Professional Plumbing Services in San Jose
Licensed Plumbers Serving Every Part of San Jose
San Jose is not one housing market, it is a dozen. A 1920s bungalow in Naglee Park and a 2015 townhome in North San Jose fail in completely different ways — and the right repair is different too.
United HVAC, Plumbing & Electrical covers the whole city: Willow Glen, the Rose Garden, Naglee Park, Japantown, Cambrian, Blossom Valley, Almaden Valley, Evergreen, Silver Creek, Berryessa and Alum Rock. Our nearest office and parts warehouse sit on Victor Court in neighbouring Santa Clara, a short drive from most San Jose addresses, which is why same-day slots are realistic here rather than a two-day window. Every job carries California contractor license #1061226 and $2 million in liability insurance, and every technician is background-checked.
What Fails, and Where, in San Jose
- Clay sewer laterals under old street trees — Willow Glen, the Rose Garden, Naglee Park. These neighbourhoods went up in the 1920s to 40s and many still run vitrified clay laterals out to the main. The mature elms and oaks that make those streets desirable push roots into every joint. If the line backs up again a few months after it was cleared, that is roots, not grease.
- Slab leaks in the post-war and 1970s tracts — Cambrian, Blossom Valley, Almaden, Evergreen. Copper supply lines were cast straight into the slab, and the valley’s expansive clay soil swells and shrinks with the seasons. That movement works the pipe until it opens a pinhole. Look for a warm patch on the floor, running water with every fixture shut off, or a water bill that jumps for no reason.
- Galvanized supply lines still in service. Anything built before roughly 1960 that has never been repiped is running steel pipe that has been rusting shut from the inside for sixty years. Brown water first thing in the morning and weak pressure upstairs are the giveaways.
- Scale from hard water. San Jose Water delivers hard water across most of the city. It settles on the bottom of a tank heater, insulates the burner from the water, and shortens the life of the unit — and it quietly clogs faucet aerators and shower cartridges along the way.
- Cast-iron drain stacks downtown and around Japantown. Older multi-storey and mixed-use buildings still carry cast iron that has scaled down to a fraction of its original diameter. Cabling it clears today’s blockage; a camera tells you whether the pipe itself is finished.
What We Handle
- Emergency and burst-pipe response — 24/7, nights and weekends included.
- Drain cleaning and hydro-jetting — kitchen lines, main lines and sewer laterals.
- Water heater repair, replacement and tankless conversion — gas, electric and heat-pump units.
- Leak detection — acoustic and thermal, so we find it without opening walls to look.
- Whole-house repiping — replacing failing galvanized supply lines with copper or PEX.
- Sewer camera inspection and trenchless repair.
- Fixtures and valves — faucets, toilets, garbage disposals, shut-offs and pressure regulators.
Permits in San Jose
The City of San Jose requires a plumbing permit for water heater replacement, repipes, sewer lateral work and most fixture relocations, and inspectors here enforce seismic strapping, correct venting and an expansion tank on new installations. We pull the permit and meet the inspector on site, so the work is on record when the house is eventually sold.
Upfront Pricing, No Trip Charge
You get a flat written price before anything is touched, not an hourly meter running while a technician walks back to the van. Estimates are free, there is no trip charge anywhere in San Jose, and the number on the quote is the number you pay. If the job turns out to be more involved than it first looked, we stop and re-quote instead of adding it to the bill.

What Our Customers Say

Pasha (technician) was very helpful. We had a clogged drain and were unable to clear it ourselves. He arrived and fixed the drain and was very clean and polite. Left everything as it was before he arrived. Highly recommend.
Pasha was very professional, he gave us a couple of options and finished the plumbing job very quickly.
As a busy homeowner I truly appreciate their ability to work around my schedule and needs. My garbage disposal recently died, and Neo was professional and offered me different options. He had the parts I needed and was able to complete the job quickly and cleanly.

Frequently Asked Questions
Yes. Our office and parts warehouse are on Victor Court in neighbouring Santa Clara, a short drive from most San Jose addresses, so same-day slots are realistic rather than aspirational. Most requests placed before mid-afternoon are handled the same day, and we run 24/7 for burst pipes, sewer backups and no-hot-water emergencies.
All of them — Willow Glen, the Rose Garden, Naglee Park, Japantown, downtown, Cambrian, Blossom Valley, Almaden Valley, Evergreen, Silver Creek, Berryessa, Alum Rock and North San Jose. There is no trip charge anywhere inside the city.
Almost certainly tree roots. Willow Glen, the Rose Garden and Naglee Park were built in the 1920s to 40s with vitrified clay laterals, and the mature street trees send roots into every joint. Cabling clears the blockage but leaves the roots; a camera inspection shows whether you need periodic jetting or a spot repair.
Yes. The City of San Jose requires a plumbing permit, and inspectors enforce seismic strapping, correct venting and an expansion tank. We pull the permit and meet the inspector, so the installation stays on record for a future sale.
A warm patch on the floor, the sound of running water when every fixture is shut off, an unexplained jump in the water bill, or damp carpet with no obvious source. Slab leaks are common in the Cambrian, Blossom Valley, Almaden and Evergreen tracts, where copper was cast into the slab over expansive clay soil. We locate them acoustically rather than opening the floor to look.
Yes. San Jose Water delivers hard water across most of the city. Scale builds on the bottom of tank water heaters, insulates the burner and shortens the life of the unit; it also collects in aerators and shower valves. Flushing the tank annually helps, and a softener or a tankless unit with a scale filter is worth considering if you have already replaced a heater early.
In San Jose, as in most Bay Area cities, the lateral running from the house to the city main is the property owner’s responsibility — the city maintains the main, not your line. We handle camera inspection, hydro-jetting, spot repairs and trenchless replacement.
Yes. California contractor license #1061226, $2 million in liability coverage, and every technician is background-checked. The license number appears on your quote.
Estimates are free and there is no trip charge in San Jose. You get a flat written price before work starts; if the job turns out to be more involved than it looked, we stop and re-quote rather than running up an hourly bill.
Yes. We answer the phone 24/7 and dispatch for genuine emergencies — burst pipes, a sewer backing up into the house, a water heater flooding a garage, or a gas smell. Call (408) 539-6936.

He had the parts I needed and was able to complete the job quickly and cleanly.Posted on Google Chaozhong LianTrustindex verifies that the original source of the review is Google. I wholeheartedly recommend United HVAC, Plumbing & Electrical. I recently hired them to replace the original 1961 HVAC ductwork in my house, and they did a wonderful, extremely professional job. I am beyond satisfied with the results. You don't just have to take my word for it--I actually took pictures of their completed work, uploaded them to Google Gemini, and asked the AI to evaluate the installation. Even the AI praised their work, calling it a "top-tier, textbook installation"! (See the screenshots below). During the bidding process, I compared United with another company. United's quote was slightly higher, but choosing them was absolutely the best decision. Their program manager, Tim, was incredibly easy to work with. He quickly identified asbestos tape on my 1961 ducts and insisted we use a C-22 licensed abatement company to remove it safely and provide all the legal documentation for future reference. The other company offered a cheaper route by doing the removal themselves, but for something as dangerous as asbestos, doing it by the book is well worth the minor price difference. I also want to give a massive shoutout to Bair (Bayar) for his exceptional craftsmanship. He is easy-going, friendly, and really listened to all of my concerns. He provided great recommendations on how the new ductwork should be organized, and actually used a machine to fine-tune and balance the air pressure throughout the house. To top it all off, he even carefully reorganized the insulation in my attic after the work was done! It's this kind of attention to detail that makes them stand out. The pictures speak for themselves. If you want true professionals who care about safety, honesty, and quality craftsmanship, go with United HVAC.Posted on Google Chaozhong LianTrustindex verifies that the original source of the review is Google. I highly recommend United HVAC, Plumbing & Electrical! From start to finish, the entire process was incredibly smooth. They handled all the permits and inspections throughout the project, which gave us complete peace of mind. Every single technician we interacted with was friendly, approachable, and truly easy to work with. I specifically want to give a massive shoutout to Max (Aiusha) and Rinat for their wonderful work. Max is super professional and highly skilled. He installed my water heater and water softener with absolute "military precision." I'm the kind of guy who has a lot of weird, specific ideas about how pipes should be routed and extra gadgets I want installed to monitor the system, and Max handled all my requests with total ease. I am also super paranoid about plumbers plowing through studs or structural beams in my 1961 house, but Max was extremely careful and treated my home's structure with the utmost respect. Rinat is also a fantastic plumber. He installed a PRV, a Moen Flo auto-shutoff valve, an RO system, and even replaced some of the old sewage pipes in my house. He really listened to all of my requests and finished the job quickly and professionally. I highly recommend him! Because of their wonderful service, I’ve officially signed up for their company's membership. I am currently working with them to redo my HVAC ductwork, and I will definitely leave another review for that project once it's done. I'm sure they will do a wonderful job there, too!Posted on Google Ritesh BediaTrustindex verifies that the original source of the review is Google. Great service. Loved the professionalism and the way fixed my plumbing problem. I would call them again.Posted on Google Ginger PerngTrustindex verifies that the original source of the review is Google. We had to replace the wax ring on our toilet. Scheduling was easy; pricing was fair (much cheaper than the other quote we got!) Our technician, Melvin, was polite and expedient. This is our second time using United and highly recommend for gas and plumbing services.Posted on Google Joseph MartinTrustindex verifies that the original source of the review is Google. Melvin was great. Fast and efficient.
