About faucet & sink repair
Faucet and sink repair covers the everyday fixtures you use the most: the kitchen and bathroom faucets, the supply valves and lines feeding them, the sink basin and its seals, and the drain assembly underneath. Most problems start small. A worn washer lets a faucet drip, a loosened compression fitting weeps a few drops a day, or mineral buildup chokes the flow at an aerator. Left alone, a slow drip wastes a surprising amount of water over a year, and a hidden under-sink leak can quietly warp a cabinet floor or feed mold.
The good news is that fixtures are one of the more approachable corners of home plumbing. Many issues come down to a few inexpensive internal parts, and the fix is straightforward for a professional once the cause is identified. The harder questions are usually whether a tired faucet is worth rebuilding or better replaced, and whether a leak is coming from the fixture itself or from the connections below. Plumbing Advisors is a national service that helps you sort out what you are dealing with and connects you with plumbing professionals who work in your area.
Signs you may need faucet and sink repair
A faucet drips when fully closed
A faucet that keeps dripping after you shut it off usually has a worn washer, O-ring, or cartridge inside. The parts are small, but the steady drip adds up on your water bill over time.
Moisture or pooling under the sink
Dampness in the cabinet, a musty smell, or water pooling on the base points to a leak at the supply connections, the drain, or a worn seal. Catching it early keeps the cabinet and floor from being damaged.
Weak pressure at one fixture
If flow is weak at a single faucet while the rest of the home is fine, the culprit is often a clogged aerator or a partly closed supply valve. Low pressure throughout the home points to a broader cause.
The handle is loose or stiff
A handle that wobbles, spins, or feels gritty to turn often means a worn cartridge or loose internal hardware. It tends to get worse with use and can lead to a drip.
Rust, corrosion, or stains at connections
Green or white crust on supply lines and fittings, or rust around the base of the faucet, signals aging connections that may be close to leaking. These are worth inspecting before they let go.
Sprayer or diverter not working
A pull-out sprayer that will not switch, leaks at the hose, or sticks in one mode usually has a failing diverter or a worn hose. It is a common wear item on kitchen faucets.
What to know
When you need it
- A faucet drips even when fully closed
- Water leaks under the sink or at connections
- Water pressure is weak at a faucet
- A fixture is loose or does not operate smoothly
Common causes
- Worn washers, O-rings, or cartridges
- Loose or corroded supply line connections
- Mineral buildup in the aerator or valve
- A failing faucet that has reached its lifespan
- Damaged seals at the sink or drain
What to check first
- Clean the faucet aerator to improve weak flow
- Check the under-sink connections for moisture
- Shut off the fixture supply valve if it is leaking
- Note whether hot, cold, or both are affected
When to call a pro
- A leak continues after basic checks
- Under-sink connections are leaking or corroded
- Low pressure persists at the fixture
- You are replacing a faucet or sink
Repair vs. replace the faucet
When a faucet acts up, the choice is usually between swapping a worn part and putting in a new fixture. A professional can tell you which makes more sense for yours.
Repair it
If the faucet body is solid and the finish is in good shape, a repair is often the practical choice. Drips, stiff handles, and weak flow frequently trace back to a washer, O-ring, cartridge, or aerator that costs little to replace. This is the budget-friendly path for a faucet that is otherwise serving you well.
Replace it
Replacement starts to make sense when parts are hard to find, the finish is corroded or pitted, the faucet has failed more than once, or the base is leaking where it meets the sink. A newer fixture can also improve flow and reliability. If you were already planning to update the look, this is often the moment to do it.
What a typical faucet & sink repair visit includes

- Replacing worn washers, O-rings, cartridges, or aerators
- Resealing or reconnecting supply lines and the drain as needed
- Installing a new faucet or sink when replacement is the better option
- Testing for leaks and confirming proper hot and cold flow

Frequently asked questions
Why does my faucet keep dripping?
A persistent drip is usually a worn washer, O-ring, or cartridge inside the faucet. These parts wear out with use. Replacing them typically stops the drip.
What causes low water pressure at one faucet?
Low pressure at a single faucet is often a clogged aerator or a partially closed supply valve. If pressure is low throughout the home, the cause is usually broader. Our low water pressure guide has more.
Is an under-sink leak urgent?
It is worth addressing soon. Even a slow leak under a sink can damage the cabinet and floor and encourage mold. Catching it early keeps the repair simple.
