A dripping or leaking kitchen faucet often needs a worn seal, cartridge, hose connection or aerator cleaned—not a whole new fixture. The right fix depends on where the water appears, whether it leaks only while running, and what type of faucet is installed. Start by drying the faucet and the cabinet below, then observe when and where water returns. Before taking anything apart, locate the shutoff valves and confirm they work. These checks can help you decide whether a straightforward repair is suitable, whether to call a handyman or plumber, and what to ask when comparing service estimates.

Kitchen faucet repair: what the leak location can tell you

Water can travel along a faucet body or countertop before dripping, so the wettest spot is not always the source. Dry the area with a towel, run the faucet briefly, and watch for the first place that becomes wet. Check both above and below the sink; a leak at a supply connection can look like a faucet problem from above.

Symptom Possible cause Useful first check
Water keeps dripping from the spout after the handles are off Worn cartridge, valve seal, washer or internal faucet component Check whether the drip continues after any brief residual water has drained
Water appears around a handle Worn seal or O-ring, a loose component, or a damaged cartridge Dry the handle and faucet body, then see whether water appears while the faucet is running or after it is shut off
Water pools around the faucet base A worn spout seal, water splashing onto the deck, or a leak from a nearby connection Dry the deck and run water into the sink without splashing; inspect underneath too
Water is inside the cabinet Supply-line connection, shutoff valve, pull-down hose, spray-hose connection or faucet-body leak Dry the cabinet, then check each connection while the faucet is used
Flow is weak or uneven Debris in the aerator or spray head, a partly closed valve, or a supply problem Check that the shutoff valves are open and inspect the removable screen or spray head

These clues narrow the possibilities but don’t confirm a failed part. For example, water around the base may come from a seal inside a swivelling spout, but it may also be splash from the sink or water running down from a hose connection. If the leak is difficult to reproduce or seems to come from inside a wall or cabinet panel, stop at observation and get professional help.

Safe checks to make before opening the faucet

  1. Identify the faucet. Note whether it has one handle or two, whether the spout swivels, and whether it has a pull-down or pull-out sprayer. Look for a model number on the faucet, packaging or installation paperwork. A brand and model can help you find the correct instructions and replacement parts.
  2. Check the shutoff valves. They are usually under the sink, connected to the hot and cold supply lines. Turn them gently; don’t force a stiff, corroded or leaking valve. If a valve will not close or begins to leak, stop and call a plumber rather than dismantling the faucet with the water on.
  3. Protect the work area. If you proceed with a repair, close the valves, open the faucet to release remaining pressure, and place a towel or small container in the cabinet. Cover the sink drain so small screws or clips cannot fall into it.
  4. Follow the faucet’s instructions. Handle attachments and internal parts differ by model. Use the specified tools and keep parts in the order they come out. If a component resists, don’t apply force that could crack the faucet or damage its finish.
  5. Match replacement parts carefully. A cartridge or seal that looks similar may not fit or seal correctly. Use the faucet model information or the manufacturer’s parts guidance, and note the original part’s orientation before removing it.

After a repair, open the shutoff valves slowly and check for leaks with the faucet both off and running. Inspect the cabinet connections as well as the faucet body. If water appears, close the valves again if it is safe to do so; don’t leave a suspected leak unattended.

Which faucet parts may need repair?

The internal design determines what can be replaced. Two faucets that look alike from above may use different cartridges or seals, so visual similarity alone is not a reliable way to choose parts.

Faucet design Components that may wear What to consider
Compression faucet, often with separate hot and cold handles Washers, valve seats or stem seals A drip may come from a worn sealing part, but damaged valve components can make a simple washer replacement insufficient
Cartridge faucet Cartridge or related seals The replacement must match the faucet model and may need to be installed in a particular orientation
Ball faucet Ball assembly, springs, seats or seals Several small parts may be involved; use a model-specific repair kit and instructions
Ceramic-disc faucet Cartridge or seals These parts can be damaged by forcing a handle or using an incompatible replacement

These categories are useful for understanding a repair estimate, not for diagnosing a faucet by appearance alone. If the handle is stiff, the cause could be a worn component or mineral buildup; forcing it can make the problem worse. A repairer should identify the faucet and explain which part has failed before replacing it.

When is a DIY fix reasonable, and when should you call someone?

A careful homeowner may be able to clean a removable aerator or replace a clearly identified, accessible part if the shutoff valves work and the faucet’s instructions are available. A simple task is a poor DIY choice if access is cramped, the faucet is corroded, a part is seized, or water continues to flow after the valves are closed.

  • Consider a simple DIY check when the problem is limited to a clogged aerator or spray head and the manufacturer’s instructions explain how to remove it safely.
  • Consider a handyman or faucet-repair service for an accessible fixture repair where the water can be shut off and the issue appears limited to the faucet or its connections. Confirm that the provider is permitted and insured to perform the work in your area.
  • Call a plumber if a shutoff valve leaks or will not operate, a supply pipe is damaged, the leak may be behind a wall, or the source remains unclear. A plumber is also the safer choice when the repair involves more than the faucet itself.

Stop using the faucet if water is leaking into a cabinet or onto nearby electrical equipment. If the water supply cannot be shut off safely, avoid further disassembly and seek urgent plumbing assistance. Local rules and the scope of a repair can affect who is qualified to do the work, so ask before booking rather than assuming every handyman service covers plumbing.

Repair or replace the faucet?

Repair is often worth considering when the fixture is secure, the problem is limited to a replaceable part, and the correct part is available. Replacement may make more sense when the faucet body is cracked, badly corroded, repeatedly leaking, or has parts that cannot be sourced. The condition of the connections under the sink matters too: a new faucet will not solve a leaking shutoff valve or damaged supply line.

Option Most suitable when Main advantage Limitation
Repair the existing faucet The fixture is in good condition and the failed component is identifiable and replaceable Can avoid replacing a functioning fixture Parts may be difficult to identify or unavailable for some models
Replace the faucet The fixture is damaged, repeatedly failing, or not practical to repair Replaces the faulty fixture as a whole May require extra work if mounting, supply connections or sink openings do not suit the new fixture
Repair the plumbing connection The leak comes from a shutoff valve, supply line or pipe rather than the faucet Addresses the actual source of water May require a plumber and will not fix a separate fault in the faucet

Ask the service provider to explain the evidence for the proposed fix: where the leak starts, which part has failed, and whether the repair includes testing afterward. If replacement is recommended, ask whether the quoted work covers removal of the old faucet, installation of the new one and any changes needed to the connections. Compare the complete scope, not just the part or labor line.

How to plan the cost of kitchen faucet repair

There is no dependable single price for every faucet repair. The cost depends on the fault, the faucet model, access under the sink, the parts required, local labor rates and whether the work can be completed in one visit. A clogged aerator is a different job from replacing a cartridge in a difficult-to-reach fixture or repairing a leaking shutoff valve.

Before approving work, ask for an estimate that separates diagnosis, labor and parts where possible. Check whether the diagnostic charge is applied to the repair, whether parts are included, and what happens if the first suspected part does not fix the leak. If the provider recommends replacing the whole faucet, ask for a separate estimate for repair when one is technically feasible.

To compare services fairly, give each provider the same information: faucet brand or model if known, number of handles, leak location, when the leak occurs, and whether water is visible inside the cabinet. Photos or a short video can help explain an intermittent leak, but they do not replace an on-site inspection. Ask who supplies the replacement parts, whether the work includes a leak test, and what warranty or workmanship coverage applies.

What to check after the repair

Run both hot and cold water, operate the handle through its normal range, and use the sprayer if the faucet has one. Look for fresh moisture around the handle, spout base, hose connections, supply lines and shutoff valves. Check again after the water has been off for a short time; a leak that appears only when the faucet is closed may not show during the first test.

If the faucet still drips, loses pressure or leaks into the cabinet, tell the repairer exactly when the problem occurs. Don’t keep tightening fittings or replacing parts at random. A clear description can help distinguish a missed faucet fault from a separate problem in the supply plumbing.

Frequently Asked Questions

Can a dripping kitchen faucet usually be repaired?

Often, yes, if the fixture is intact and the failed cartridge, washer, seal or other part can be identified and replaced. Repair may be impractical if the faucet is badly damaged or the required part is unavailable. The faucet’s condition and the source of the drip matter more than the drip alone.

Why does my faucet leak only when I turn it on?

Water may be escaping from a spout seal, hose connection or another pressurized part that leaks only during use. Dry the faucet and cabinet, then watch where moisture first appears while the water is running. If you cannot locate it safely, arrange an inspection rather than guessing at parts.

Should I replace the cartridge or the entire faucet?

A cartridge replacement can be a practical repair when the faucet body is sound and the correct cartridge is available. Consider replacement if the fixture itself is damaged, has recurring faults, or cannot be repaired with accessible parts. Ask for the repair and replacement options to be explained before choosing.

Can I use the faucet if it is leaking underneath the sink?

A leak inside the cabinet can damage stored items and the surrounding area, and the source may be a supply connection rather than the faucet. If water is actively collecting, stop using the fixture and close the shutoff valves only if they operate safely. Call a plumber if a valve or pipe is leaking or cannot be shut off.

What information should I give a repair service?

Share the faucet’s brand or model if known, whether it has one or two handles, where water appears, and whether the leak occurs when the faucet is on or off. Mention any pull-down sprayer and the condition of the shutoff valves. This helps the provider assess the likely parts and whether the job is within their service scope.

For kitchen faucet repair, identify the first point where water appears before deciding on a part or a replacement. If the fixture is intact and the fault is localized, a repair may be enough; if the valves, pipes or leak source are uncertain, bring in a qualified plumbing professional. A clear diagnosis and an itemized estimate make it easier to choose the right fix without paying to replace a faucet that may still be serviceable.
