Faucet & Sink Repair in Costa Mesa, CA
Faucet and sink repair covers dripping taps, leaks under the cabinet, low flow and new fixture installs in kitchens, bathrooms and laundry rooms. In Costa Mesa, CA, most repairs are a cartridge, a supply line or a drain connection, and most take a single visit.
Leaks under the cabinet: where to look
Water in a sink base has only a few sources. Dry the cabinet, run the faucet, and watch these spots.
- The supply lines and the small shutoff valves at the wall.
- The drain tailpiece and the slip nuts on the P-trap.
- The base of the faucet, where water runs under the deck.
- The dishwasher drain connection or the garbage disposal.
A leak at the disposal body itself points to garbage disposal repair.
Old shutoff valves are the hidden problem
The small angle stops under sinks in many 1950s and 1960s homes have not been turned in decades. When they are finally closed, they often leak at the stem or refuse to shut off at all.
We check both valves before starting a faucet job. Replacing a seized stop at the same time costs little and means you can shut off that sink in an emergency.
Supply connectors deserve the same check. Braided steel connectors last longer than old solid or plastic lines, and they are cheap to replace while the faucet is off.
Repair or replace the faucet
| Situation | Better choice | Why |
|---|---|---|
| Drip from a newer brand-name faucet. | Repair. | Cartridges are widely available. |
| Drip from a decades-old or unbranded faucet. | Replace. | Parts may no longer exist. |
| Corroded body or cracked handle. | Replace. | Repairs will not hold. |
| Low flow only. | Clean the aerator first. | Mineral buildup is a common cause. |
California limits new bathroom faucets to 1.2 gallons per minute and kitchen faucets to 1.8. A new faucet will feel different from a decades-old one, but a good model still fills a pot quickly.
Local water and your fixtures
Mesa Water's groundwater averaged 6.4 grains per gallon of hardness in 2024. That leaves some white buildup on aerators and showerheads over time. Soaking the aerator in white vinegar restores flow in most cases.
Chloramine in the water can shorten the life of some rubber seals and O-rings. When a faucet starts dripping again soon after a repair, we use seals rated for chloramine.
Kitchen faucet features worth knowing about
Pull-down sprayers are the most requested upgrade and install like any single-hole faucet. Touchless faucets need power, either batteries under the sink or an outlet, so check the cabinet before you buy one.
A pot filler over the range needs a new water line run through the wall, which is a bigger job than a faucet swap. A filtered-water tap needs a hole in the sink or countertop and space under the sink for the filter housing.
If the sink has more holes than the new faucet needs, a deck plate covers them. If it has fewer, a granite or quartz countertop needs a professional to drill it, so plan that before the plumber arrives.
Choosing a faucet that lasts
The parts you cannot see decide how long a faucet lasts. Ceramic disc cartridges hold up better than older rubber-washer designs, and they are less affected by chloramine. Solid brass bodies outlast thin plated castings.
Brand support matters too. Faucets from makers that keep cartridges in stock for years can be repaired in minutes. Unbranded faucets often have to be replaced when the first cartridge fails.
What faucet and sink work costs
| Factor | Why it matters |
|---|---|
| Repair or replace | A cartridge swap costs less than a new faucet install. |
| Shutoff valves | Replacing seized angle stops adds a small cost. |
| Sink type | Undermount and farmhouse sinks take more time than drop-in. |
| Fixture supply | Installing a faucet you bought versus one we supply. |
| Access | Tight vanities and deep cabinets take longer. |
Insurance note: slow leaks under sinks are usually treated as maintenance. Fix them early before the cabinet floor rots.
