Faucet Installation
Faucet is the most common water fixture in your house. You most probably have 4 or 6 of them in your kitchen, bathroom. United HVAC, Plumbing & Electrical provides faucet installation for kitchen, bathroom, and outdoor fixtures across the Bay Area, including San Jose, Santa Clara, Saratoga and other Bay Area cities. We remove handles, replace supply lines, testing the system.
What Is Professional Faucet Installation and When Do You Need It?
Professional faucet installation means removing the old faucet, connecting new supply lines and angle stop valves under the sink, and confirming pressure and drainage. You need it when a faucet leaks at the base, won’t hold a temperature set. Most basic faucets are installed in one to two hours.
Types of Faucets We Install
Kitchen faucet installation covers single-hole pull-down, bridge-style, and pre-rinse units. Bathroom faucet installation includes centerset, widespread, and wall-mount fixtures, and shower faucet installation covers single-handle, two-handle, and thermostatic valve systems accessed through a wall panel. Most of models are Moen, Kohler or Glacier Bay. Sometimes we see European Hansgrohe models.
Signs It’s Time to Replace Your Faucet
A faucet dripping at the base after shutoff usually means broken cartridge. Hard-water buildup, common in older San Jose and Santa Clara homes, corrodes internal valves until repair parts aren’t worth installing. A loose handle or a unit predating 1994 low-flow standards generally means replacement is better than repair.
How Faucet Installation Works: What to Expect on Service Day
You set up an appointment with our call center or online on the web site. Our plumber arrives with the new faucet, or installs one you’ve purchased. He shuts off the water, removes the old fixture, and connects the new faucet with new supply lines. We cannot use old supply lines to a new faucet. The visit usually takes one to two hours and ends with a pressure and leak check, with no demolition needed for a standard sink-mounted replacement.
Pre-Installation Assessment and Shutoff Verification
Before removing anything, plumber check the angle stop valves under the sink. In homes built before the 1980s these valves are often corroded or seized and may need replacing first. Therefore, we have to locate main shut off valve as well. We also confirm rough-in spacing and hole count match the new fixture before starting.
Installation, Testing, and Final Calibration
Once the old unit is removed, we install new supply lines, seat the faucet body, and connect it to the angle stop valves. We then run hot and cold water at full pressure, checking every connection for leaks and confirming the handle calibrates correctly. Pull-down and touch-activated models also get a spray-function and sensor check.
Faucet Installation Cost in the Bay Area
That’s the most common question. Faucet installation in the Bay Area typically runs from $300–$800 in labor for a standard kitchen or bathroom swap. Price depends on faucet type and whether the hole configuration is changing. We quote a flat rate at a job site before work begins.
Factors That Affect the Final Price
Swapping one single-hole kitchen faucet for another is usually simple, since the rough-in already matches. Converting a three-hole setup to single-hole, or installing a heavier faucet needing added support, adds labor and sometimes a deck plate. Corroded valves or disconnecting a garbage disposal during a sink faucet installation also raise the cost. If we do multiple jobs at one visit we can offer a discount. Members with United’s “Home protection plan” get 10% member’s discount.
Supply-Only vs. Supply-and-Install: What’s the Difference?
Supply-and-install pricing covers the faucet plus labor and the visit, useful for one quote covering the whole job. Supply-only pricing applies when you’ve already bought a faucet and need installation labor only — common for kitchen sink faucet installation tied to a remodel. We confirm fit with your countertop cutout and sink configuration either way.
Why Bay Area Homeowners Choose United HVAC, Plumbing & Electrical for Faucet Installation
Licensed, Insured, and Local
We train our plumbers weekly. Our team holds a California C-36 plumbing license, so the work meets state code for water supply connections. Insurance protects you financially if a connection fails or a fixture is damaged mid-job. Being Bay Area–based, we know the shutoff valve conditions in typical of homes in Sunnyvale, Belmont, Atherton, Foster city, San Jose and other Bay Area cities.
25+ Years Installing Faucets Across the Bay Area
Our technicians and supervisors installed and replaced faucets in Bay Area homes for more than 25 years. That history means we catch compatibility issues before they become a return trip, like a faucet that won’t seat against a granite cutout. Most faucet installation services we perform need no second visit.
Same-Day Service With Upfront Flat-Rate Pricing
Most new faucet installation requests are scheduled same-day or the next morning, since a broken faucet isn’t something most households want to live with. Before work starts, after assessing the work we give a flat-rate price based on faucet type and what we find during the pre-installation check, not an estimate that shifts mid-job. That price covers labor, standard supply lines, and a leak check. Although our call canter and service back office aware of plumbing services we don’t provide prices over the phone.

Frequently Asked Questions
A new faucet dripping right after installation is usually a loose supply line connection, a misseated aerator, or a cartridge that wasn't fully engaged — rarely a defect in the faucet itself. Tightening the connections or reseating the cartridge typically fixes it. We run a pressure and leak test before calling any installation complete.
Almost always, if the valves are more than 15–20 years old, corroded, or hard to turn, we recommend replacing them in the same visit. A new faucet on a failing valve often means a leak or a second service call within months. Replacing both together avoids a separate trip later.
Yes, we can install faucets homeowners bought themselves in retail stores or online. Before the appointment, we confirm the model. This is typically billed as a supply-only installation.
A compression valve uses a rubber washer that tightens against a seat to stop flow — the older design, prone to dripping as the washer wears. A ceramic disc valve uses two interlocking discs that rotate to control flow and rarely needs washer replacement, making it standard in most modern faucets. A compression-valve faucet that drips often is usually due for replacement.
Yes, but it typically needs a deck plate or escutcheon to cover the two unused holes in the countertop or sink deck. Sometimes it goes with a new sink installation.

Posted on Google Omied LeleTrustindex verifies that the original source of the review is Google. 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.Posted on Google Liang KatherineTrustindex verifies that the original source of the review is Google. Fantastic service! We really enjoyed working with United plumbingPosted on Google Natalia ShreveTrustindex verifies that the original source of the review is Google. Pasha was very professional he gave us a couple of options and finished the plumbing job very quicklyPosted on Google Just JaniceTrustindex verifies that the original source of the review is Google. 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 my different options. 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.
