Faucet repair in San Jose usually means replacing a worn cartridge, O-ring or washer to stop a drip, or clearing scale from an aerator to restore flow; faucet replacement includes checking the stop valves and supply lines, since old stops often fail when a faucet is changed.

Repair the faucet or replace it
A dripping faucet is usually a worn cartridge or seal, and most quality faucets have replacement parts. Replacing the faucet makes sense when parts are unavailable, the finish has failed, or you simply want a different fixture.
Low flow is usually scale in the aerator or cartridge, which is common with hard water and quick to clear.

Cartridge replacement
Single-handle and many two-handle faucets use cartridges that control flow and temperature. When they wear, the faucet drips, leaks at the handle or mixes poorly. We identify the brand and model, fit the matching cartridge and seals, clean scale from the valve body, and lubricate the new cartridge with silicone grease. Getting the exact part matters; a close match often drips again within weeks, so we check the model and the cartridge style before ordering rather than guessing from the handle shape.
Kitchen faucet swap
A new kitchen faucet may be a single hole, a three-hole deck or a pull-down with a sprayer weight. We remove the old faucet, clean the deck, set the new one with the right gasket or plate, and connect new braided supplies. If the stops are old or will not close, we replace them while the water is off. We also connect the sprayer hose and weight so they move freely around the disposal and drain lines without catching every time the sprayer is pulled out.
Bathroom faucet swap
Bathroom faucets come as centerset, widespread and single-hole designs, and the choice depends on the holes in your sink or counter. We install the faucet and its drain assembly, set the pop-up stopper so it seals and opens properly, and connect new supplies. A widespread faucet has hot and cold valves connected underneath, which takes more care to fit in a tight cabinet without kinking any lines or crowding the drain. We test both valves and the stopper before we leave, so the first use is not the moment a small leak shows up.
Outdoor spigot
Outdoor hose bibs drip at the packing nut or washer and sometimes leak inside the wall. We repair or replace the bib, choose a model with a built-in vacuum breaker where appropriate, and seal the wall penetration. A leak that shows inside the house when the hose is on usually means the bib's internal tube has split, which calls for a replacement rather than a new washer, and we check the wall behind it for dampness that may have been building for a while.
Local context
Faucets in San Jose's hard water
Faucets in San Jose take a steady load of mineral scale, which shows up first as white crust on aerators and then as stiff handles and worn cartridges inside the valve. When we service a faucet here we clean the aerator and valve body as part of the job, and we tell owners that a quick soak of the aerator in vinegar every few months keeps flow up between visits. It is a small habit that noticeably extends cartridge life.
