Faucet repair in Palo Alto, CA usually comes down to a small part that has stopped sealing: a washer, an O-ring, or a cartridge. Works Plumbing finds which one, matches the replacement to your faucet, and stops the drip at its source.

We repair kitchen, bathroom, tub, and laundry faucets, plus the supply lines and shutoff valves underneath them.
Faucet dripping or leaking under the sink? Book faucet repair with Works Plumbing.
| Symptom | Likely cause | Typical repair |
|---|---|---|
| Drip from the spout | Worn washer, seat, or cartridge seal | Replace the washer and seat or the cartridge |
| Leak at the base of the handle | Failed O-ring or packing | Replace the O-rings or packing |
| Leak under the sink | Loose or worn supply line, failed shutoff | Replace the supply line or the valve |
| Low flow from one faucet | Clogged aerator or cartridge screen | Clean or replace the aerator and screen |
| Stiff or loose handle | Worn cartridge or stem | Replace the cartridge or stem |
| Pull-down spray leaking | Worn hose or O-ring | Replace the hose or seal |
| Hot and cold mixed wrong | Failed cartridge or reversed lines | Replace the cartridge or correct the lines |
Kitchen faucets work hardest. Pull-down and pull-out sprayers add a hose, a weight, and extra seals, and those parts fail on their own schedule. We check the hose and the spray head along with the valve.
Bathroom faucets see less use but often have pop-up drains and small supply lines that leak at the connections. Widespread faucets with separate handles have two valves to service instead of one.
Tub fillers and tub and shower faucets sit in the wall. Their stems and cartridges are reached from the front, and a drip at the tub spout usually means a worn seal in the valve body behind the handle.
Palo Alto’s water is not very hard, but it does carry minerals. The 2025 report lists hardness from 8.1 to 112 ppm, with an average of 62 ppm.
At those levels, buildup is usually modest. It still shows up over time in aerators and the small screens inside some cartridges, where it can reduce flow or make a handle feel gritty. Part of every faucet repair is cleaning or replacing the aerator so the faucet flows properly when we leave.
You get an upfront price after we identify the problem and before we replace anything.
Palo Alto has a long building history. Census estimates show the 1950s as the largest single decade of home construction, at 25.1 percent of units, and 13.3 percent of units were built in 1939 or earlier.
In older houses, a faucet may be decades old or a discontinued model. We look for parts first. If parts are no longer available, we explain the options, including a replacement faucet that fits the existing sink holes where possible.
Older homes also tend to have older shutoff valves. If a shutoff will not close fully, we recommend replacing it during the repair, because the next faucet or toilet repair depends on it working.

Does Palo Alto’s chloramine affect my faucet?
The City of Palo Alto Utilities uses chloramination to keep a disinfectant residual in the water. Over years of contact, rubber washers, O-rings, and cartridge seals can wear. When we repair a faucet, we check all the seals we can reach, not just the one that failed.
Is Palo Alto water hard enough to clog my faucet?
The City’s 2025 report lists hardness of 8.1 to 112 ppm, averaging 62 ppm. Buildup is usually modest, but aerators and cartridge screens can still collect deposits over time. We clean or replace them during a repair.
Can you fix an older faucet in a historic Palo Alto home?
Often, yes. We look for replacement parts first. If the model is discontinued, we explain the options, including a new faucet that fits the existing sink holes where possible.
Why is my faucet leaking under the sink but not at the spout?
Under-sink leaks usually come from a supply line, a shutoff valve, or the connection at the faucet base. We trace the drip to its source before replacing anything.
My faucet has low flow but the rest of the house is fine. Why?
That points to the faucet itself, most often a clogged aerator or a screen in the cartridge. We check those first.
Should I replace my shutoff valves too?
If a shutoff will not close fully or weeps at the stem, yes. We test them during every faucet repair and recommend replacement only when they fail.
A drip wastes water every hour it runs. Contact Works Plumbing for faucet repair with matched parts and upfront pricing.

A look at real Works jobs around the Peninsula.
Every faucet seal in Palo Alto sits in treated water around the clock. The City of Palo Alto Utilities buys Hetch Hetchy regional water, and its 2025 Annual Water Quality Report lists the treatment steps. They include UV and chlorine disinfection, pH adjustment for corrosion control, and “chloramination for maintaining disinfectant residual.”
That residual is the point. Chloramine is meant to stay in the water all the way to your tap so it remains disinfected in the pipes. The report shows chlorine, including chloramine, in the distribution system at 0.44 to 3.41 ppm in 2025.
Rubber and elastomer parts inside a faucet are exposed to that water constantly. Over years of contact, washers, O-rings, and the seals inside cartridges can harden, swell, or lose their shape. When a seal stops conforming to its seat, a drip starts at the spout or a leak appears at the handle.
This affects how we repair a faucet. We do not stop at the part that failed first. When we open the valve, we check every seal we can reach, because the others have had the same exposure. Where the faucet maker offers a replacement seal kit or cartridge, we use those parts so the repair fits the valve as designed.
We also serve these neighboring Peninsula towns.
