What it is
A leaky faucet is a fixture that drips or seeps water from the spout, handle or base when it should be fully closed. Over time, the small internal parts that seal the water wear down, loosen or collect mineral buildup.
Faucets come in a few common styles: compression, cartridge, ball and ceramic disc. Each uses a different internal part to control flow, so the source of a leak depends on the design you have.
A small drip can look harmless, but it can waste water, stain a sink, and sometimes point to a bigger issue such as corroded fittings or a worn valve seat.
How it’s traditionally been approached
The traditional approach starts with shutting off the water, either at the shutoff valves under the sink or at the main supply, then opening the faucet to relieve remaining pressure. Plug the drain so small parts don't fall in.
From there, people commonly remove the handle, look at the internal parts, and compare them to the faucet's make and model. Worn washers, O-rings or cartridges are often swapped for matching replacements, and mineral deposits are cleaned off. Manufacturer instructions and parts diagrams are usually the best reference.
Others skip the repair and replace the whole faucet, especially when parts are hard to find or the finish is worn. Both routes are reasonable. The right choice depends on the faucet's condition, your comfort with tools, and your budget.
How the right repair pro may help
The right plumbing and faucet repair pro may help identify exactly why a faucet is leaking, which can save guesswork when the faucet is older, has no visible brand, or keeps dripping after a DIY attempt. They may also check the shutoff valves, supply lines and connections underneath.
A visit generally involves looking at the fixture, shutting off water, inspecting or replacing worn parts, and testing for leaks. If the problem is bigger, such as a corroded valve or a leak inside the wall, a pro may explain your options.
Good questions to ask include: Are you licensed and insured for plumbing work in my area? Will you provide a written estimate before starting? Do you recommend repair or replacement, and why? Is any work covered by a warranty? Costs vary, so compare written estimates.
The bigger picture
A constant drip can quietly wear on your peace of mind. It adds to the to-do list, can raise worries about water waste and damage, and may keep you from enjoying your home. Taking a small, steady step, whether DIY or hiring help, often brings relief.
Deciding between DIY and hiring out is also a financial and time choice. Self-reliance is satisfying, and so is knowing when to hand a job off. If the cost of help is a concern, Providers.plus may be a useful place to explore support options. Neither path is wrong.
Keep in mind
- Always shut off the water before taking a faucet apart, and keep track of small parts as you remove them.
- If a leak is near electrical outlets, appliances or inside a wall, stop and call a licensed plumber, since water and electricity can be dangerous together.
- Plumbing often requires state or local licenses and sometimes permits, so confirm a pro's license and insurance before hiring.
- Costs vary by faucet type, parts and location, so ask for a written estimate and don't rely on general figures.

Frequently asked questions
How do I fix a leaky faucet myself?
Most DIY fixes begin by turning off the water supply, plugging the drain and disassembling the handle to reach the internal parts. Worn washers, O-rings or cartridges are commonly replaced with matching parts, then the faucet is reassembled and tested. Check the manufacturer's instructions for your model, and call a plumber if you're unsure.
Why is my faucet dripping when it's turned off?
A dripping faucet usually means an internal seal, washer, O-ring or cartridge is worn or dirty. Mineral buildup or a damaged valve seat can also keep the faucet from closing fully. The exact cause depends on your faucet type.
Should I repair or replace a leaky faucet?
It depends on the faucet's age, condition and parts availability. Repair can make sense when a single part is worn, while replacement may suit older, corroded or hard-to-fix models. A plumbing pro can give an opinion and a written estimate for either route.
When should I call a plumber for a leaky faucet?
Call a plumber if the leak continues after you replace parts, if shutoff valves won't work, or if you see corrosion or water around the base or under the sink. Also call if you're not comfortable with the work. Water near electrical items is a reason to stop and get help.
Do I need a licensed plumber to fix a leaky faucet?
Requirements vary by state and locality, and some minor repairs by homeowners are allowed while hired work may require a license. Check your local rules and ask any pro for proof of license and insurance. Permits may apply to larger plumbing changes.
How much does it cost to fix a leaky faucet?
Costs vary widely depending on the faucet type, parts needed, your location and the pro's rates. The best approach is to request a written estimate before work begins and compare more than one if you can.
