A dripping faucet at one drip per second wastes over 3,000 gallons per year. Past the water cost, the drip often signals a worn cartridge or deteriorated seat-and-spring assembly that will worsen over time — eventually leaking continuously or becoming stiff and difficult to operate. Masters Plumbing Service's faucet techs in Los Altos, CA identify the specific valve type in your fixture, source the correct replacement cartridge or repair kit, and restore full, drip-free operation in a single visit.

Our Qualifications

4 Things That Set Our Faucet Repair Service Apart in Los Altos, CA

Faucet repair looks simple until the wrong cartridge is installed, a seat-and-spring assembly is put in backwards, or a corroded packing nut strips during removal. Our techs know the specific disassembly sequence for the faucets they work on in Los Altos, CA.

🔩

Valve-Type Specific Expertise

Ceramic disc faucets from brands like Moen's newer series, American Standard, and European brands use a pair of ceramic discs that rarely fail but can crack from thermal shock (sudden cold water on a hot disc). Our techs carry common disc cartridge replacements for major brands.

🏷️

Brand Knowledge Across Major Lines

Moen, Delta, Kohler, Price Pfister, American Standard, Grohe, Hansgrohe — each brand uses proprietary cartridge and valve designs that are not interchangeable. Moen uses their own 1200 and 1225 cartridge system; Delta uses ball valves in older fixtures and cartridges in newer ones; Kohler uses Rite-Temp pressure-balance cartridges in shower valves.

🚿

Shower & Tub Valve Specialists

Shower valves — particularly pressure-balance and thermostatic mixing valves — are more complex than a kitchen sink faucet and have safety implications if repaired incorrectly. We carry cartridges for the major pressure-balance valve brands common in Los Altos, CA homes and understand the anti-scald setpoint calibration that should be verified after any shower valve cartridge replacement.

💧

Under-Sink Leak Diagnosis

Leaving a slow under-sink leak unaddressed damages the cabinet interior and subfloor. We identify the source, quote the repair, and execute it same visit in most cases.

Our Faucet Services

Every Faucet Repair We Handle in Los Altos, CA

Here's the full range of faucet repair work our techs handle in Los Altos, CA — by fixture type and by symptom.

Kitchen

Kitchen Faucet Repair & Replacement

Older kitchen faucets with two separate handles use compression valves — each handle has a rubber seat washer that wears and needs periodic replacement. We stock washers and seat tools for these older designs, which are still common in Los Altos, CA homes built before 1980.

Bathroom

Bathroom Sink Faucet Repair

Two-handle bathroom faucets (separate hot and cold) are often compression or ceramic disc designs. A drip from a two-handle set almost always comes from one side only — telling us which handle's valve needs attention.

Shower

Shower Valve Cartridge Replacement

After cartridge replacement, we verify anti-scald calibration — the maximum hot water limit set by the cartridge rotational stop — to confirm the valve won't deliver scalding water at full hot even if a supply pressure event occurs.

Outdoor

Outdoor Spigot & Hose Bibb Repair

Freeze-proof (anti-siphon) hose bibbs found in colder Los Altos, CA climates have a longer stem that shuts water off 8–12 inches inside the heated wall. When these fail or freeze-crack internally, the whole bibb typically needs replacement to restore the freeze-protection function.

Low Flow

Aerator Cleaning & Flow Restoration

Persistent low flow after aerator cleaning points to a partially failed cartridge that's not opening fully, or a kinked supply hose under the sink. We trace the restriction and resolve it.

Replacement

Full Faucet Replacement

When a faucet is discontinued (no available replacement cartridge), heavily corroded at the body, or simply past useful life, we replace the fixture. We supply faucets in the common hole configurations (single-hole, three-hole, widespread) and in finishes to match your existing hardware — chrome, brushed nickel, oil-rubbed bronze.

Our Process

How Our Faucet Repair Process Works in Los Altos, CA

We identify the valve type before ordering or installing any part. The right cartridge for your faucet brand is what produces a lasting result — not a generic part that fits loosely.

Call & Describe Your Faucet Symptom

If you know the brand — Moen, Delta, Kohler, Price Pfister — tell us. If not, the tech will identify it on-site from the valve body and handle design.

Valve Type Identification & Diagnosis

For many major-brand cartridges — Moen 1225, Delta RP46074, Kohler GP30413 — the part is on the truck and the repair proceeds immediately.

Flat-Rate Quote & Repair Execution

You receive a flat-rate quote covering parts and labor before the water is shut off under the sink. Common repairs — cartridge replacement, ball assembly rebuild, aerator service — are straight-forward pricing with no variable labor component.

Verify Zero Drip Before Leaving

After repair, we run the faucet through the full temperature range, check the spout, base, handle, and supply connections for any drip, and confirm the aerator flow is unrestricted. The repair is complete when we can demonstrate it's dry and flowing correctly.

Customer Reviews

Real Faucet Repair Reviews from Los Altos, CA

★★★★★

My kitchen faucet had been dripping for two years — I kept putting it off. Masters Plumbing Service's tech identified it as a Delta ball-type faucet and had the complete repair kit on his truck: new ball, springs, seats, and O-rings. The whole rebuild took 40 minutes. The faucet moves smoothly now and there's absolutely no drip. I only wish I'd called sooner given how much water I was wasting.

— K. Svensson, Los Altos

★★★★★

Had a hose bibb that dripped at the packing nut all summer. Tech replaced the packing material and seat washer in 20 minutes. Also told me the freeze-proof stem length was correct for my wall depth, which was reassuring heading into winter.

— P. & G. Delacroix, Los Altos, CA

★★★★★

Full bathroom faucet replacement — my old two-handle fixture was discontinued and no cartridges were available. Masters Plumbing Service supplied a quality Moen single-handle faucet in the same 4-inch centerset configuration, removed the old fixture, replaced the supply lines with braided steel, and installed the new unit. Clean, level installation. Also replaced both angle stop valves under the sink since the originals were 20 years old and barely turned.

Common Questions

Faucet Repair FAQ for Los Altos, CA Homeowners

The more important issue: a drip that starts slow almost never stays at one drip per second. The cartridge or seat washer continues to deteriorate, worsening the leak until it's a steady stream or a handle that no longer shuts off at all.

For most faucets from established brands — Moen, Delta, Kohler, Price Pfister — replacement cartridges and repair kits are available and the fixture is worth repairing. We carry or can source these parts and prefer repair over replacement when the faucet body itself is in good condition.

A shower that fluctuates only at extreme handle positions (scalding at full hot, freezing at full cold) may actually have a correctly functioning but incorrectly set anti-scald stop — a mechanical rotational limiter on the cartridge that's adjustable without cartridge replacement.

If the stiffness is in a ball-type faucet, the cam and packing assembly may be binding — a rebuild kit with new cam, packing, and springs typically resolves it. We assess which type you have and quote accordingly.

Cartridge faucets use a replaceable ceramic or plastic cartridge that slides in and out of the valve body — repair means pulling the old cartridge and installing the new one in the correct orientation. Ball faucets use a rotating stainless-steel or brass ball with ports that align with supply inlets — repair means a rebuild kit with new ball (if scored), springs, seats, and O-rings installed into the cleaned valve body.

Cartridge replacement on a standard bathroom or kitchen faucet: 30–45 minutes. Ball faucet rebuild: 45–60 minutes. Shower pressure-balance cartridge replacement and anti-scald verification: 60–90 minutes. Aerator cleaning: 15 minutes. Full faucet replacement (fixture supplied): 60–90 minutes.
