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 β eventually leaking continuously or becoming stiff and difficult to operate. Masters Plumbing Service's faucet techs in Modesto, 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.

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 Modesto, CA.
Ball faucets, cartridge faucets, ceramic disc faucets, and compression faucets all fail differently and require different repair approaches. A ball-type faucet drips from a worn ball, springs, seats, or O-rings β all small parts that come in a manufacturer-specific repair kit. A cartridge faucet drip is almost always solved by cartridge replacement. Knowing which type you have before touching it determines whether the repair takes 30 minutes or 2 hours.
Moen, Delta, Kohler, Price Pfister, American Standard, Grohe, Hansgrohe β 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.
Thermostatic shower valves (separate volume and temperature controls) are premium fixtures found in master baths where comfort and safety depend on correct cartridge specification. We don't substitute cheaper cartridges on thermostatic valves.
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.
Here's the full range of faucet repair work our techs handle in Modesto, CA β by fixture type and by symptom.
Older kitchen faucets with two separate handles use compression valves β 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 Modesto, CA homes built before 1980.
Single-handle bathroom faucets use cartridge valves β one cartridge controls both hot/cold mixing and volume. When the cartridge wears, the result is a drip that typically starts slowly and worsens over months. We identify the cartridge model by the faucet brand and replace it with the correct OEM cartridge.
After cartridge replacement, we verify anti-scald calibration β the maximum hot water limit set by the cartridge rotational stop β to confirm the valve won't deliver scalding water at full hot even if a supply pressure event occurs.
Outdoor hose bibbs fail in two ways: a dripping spout (worn stem packing or seat washer) or a leak at the packing nut behind the handle (deteriorated packing material around the stem). Most hose bibb repairs involve replacing the seat washer and packing without removing the body from the wall.
Reduced flow at a kitchen or bathroom faucet is almost always a clogged aerator β the small screen-and-flow-restrictor assembly at the tip of the spout. Mineral scale from hard water accumulates in the aerator mesh over time, progressively reducing flow to a trickle. Aerator cleaning or replacement restores full rated flow in minutes.
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 β chrome, brushed nickel, oil-rubbed bronze.
Here's exactly how a Masters Plumbing Service faucet repair call runs in Modesto, CA.
Drip at the spout? Leak at the base? Stiff handle? Low flow? Knowing the symptom and, if possible, the faucet brand lets us arrive with the most likely replacement parts already stocked on the truck.
The tech identifies the faucet's valve type (ball, cartridge, ceramic disc, or compression), locates the specific cartridge or repair kit number for that model, and checks whether the required part is on the truck or needs to be sourced.
You receive a flat-rate quote covering parts and labor before the water is shut off under the sink. Common repairs β cartridge replacement, ball assembly rebuild, aerator service β are straight-forward pricing with no variable labor component.
We also confirm the angle stop valves under the sink operate β a seized stop valve that can't shut off in a future emergency is a problem worth noting while we're already under the cabinet.

My kitchen faucet had been dripping for two years β 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.
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.
Low flow in the master bath β I assumed the pressure regulator was failing. Tech cleaned the aerator (heavily scaled), and flow went from a trickle to full pressure immediately. 10-minute fix, saved me from chasing a pressure problem that didn't exist.
