Read the leak: where the water shows up
Start with where the wetness appears, and whether it happens only when the faucet is running.
| Where you see water | Likely cause | What the plumber does |
|---|---|---|
| Drip from the spout after you shut it off. | Worn cartridge, washer or valve seat. | Replaces the cartridge or washer and smooths or replaces the seat. |
| Water pooling around the base of the handle. | Failed O-ring or packing. | Removes the handle, swaps the O-ring set and reassembles. |
| Water at the base of the spout or on the deck. | Worn seals where the spout swivels or mounts. | Replaces the spout seals or the whole fitting if the body is corroded. |
| Wet cabinet floor under the sink. | Cracked supply line or leaking shutoff valve. | Replaces the line or valve and checks the fittings above. |
| Water that only appears when the faucet is on. | Loose or cracked fitting, or a pinhole in the faucet body. | Tightens or replaces the fitting, and may recommend a new fixture. |
A leak that appears only under pressure, or one that drips slowly in a cabinet, is easy to miss for weeks.
Why one drip per second adds up
A faucet that drips once every second wastes roughly 3,000 gallons a year by commonly cited estimates. Your water bill will show it before the sink does. If you see the bill climb while no one has changed habits, check every faucet, not only the one you hear.
A quiet way to test is to dry the basin and the cabinet floor with a paper towel, then look again in an hour. The paper shows a leak that a glance would miss. If the drip stops when the shutoff valve under the sink is closed, you have confirmed that the leak is in the faucet and not a pipe in the wall.
What to do the moment you see water
These steps take a couple of minutes and prevent a cabinet or floor from soaking.
- Close the stop valveTurn the small oval handle under the sink clockwise. If it will not move or it weeps, close the main shutoff to the house.
- Dry and photographWipe the area, then take photos of the leak and any damage. Landlords and insurers often ask for them.
- Put a bowl or towel under itCatch the drip and keep water off a vanity base, which can swell when it stays wet.
- Note the age and styleCheck whether it has one handle or two, and when it was last replaced. That tells the plumber what parts to bring.
Cartridge, ball, disc or compression: why the style matters
Compression faucets have two handles and use rubber washers that press on a seat. They are the simplest to repair. Single-handle faucets use cartridges, ball assemblies or ceramic discs, each with its own replacement parts.
Parts for older or discontinued models can be hard to find, and that changes the decision. If a repair kit costs nearly as much as a new fixture and the finish is worn, replacing the faucet is usually the better use of a visit. For that case a plumbing installation of a new faucet and fresh supply lines is a clean solution.
Signs the faucet is not the real problem
A leak that keeps coming back after repair deserves a wider look.
- Water appears under the sink even when the faucet has not been used for hours.
- The cabinet back wall or the wall behind the vanity is damp or stained.
- The drain trap or the pop-up assembly drips when the basin fills.
- A ceiling stain shows up in the room below the bathroom.
- Pressure drops at the sink while other fixtures are fine.
- The water meter moves with every fixture off.
When the leak is hiding
If the faucet is dry and the meter still moves, the leak is somewhere else. A hidden slab or wall leak needs leak detection service, which uses acoustic and thermal tools to find a pipe leaking behind finished surfaces. Digging or opening drywall without that step often misses the source.
Do not keep tightening a leaking compression nut with a large wrench. Overtightening cracks brass fittings and turns a drip into a spray.
What shapes the quote for a faucet repair
Price follows the faucet style, the availability of parts, whether the shutoff valves still work, and how much mineral buildup has frozen the fittings in place. A stuck stop valve can turn a cartridge swap into a valve replacement too. The plumber confirms these on arrival and states a clear price before work starts.
Insurance rarely pays for a worn washer, but it may respond to water damage from a sudden supply-line burst. Save the photos.
Middletown, DE: flush the tap after a faucet repair
After a repair, the water that sat in the faucet and supply line for hours can pick up metals from home plumbing. The town's water quality report advises running a tap for 30 seconds to 2 minutes after water has sat for several hours, before drinking or cooking. Do that after any repair that disturbed the faucet, and clear debris from the aerator by unscrewing it and rinsing the screen.
The report also says lead in drinking water comes mainly from service lines and home plumbing, and the town cannot control materials used inside homes. If you want to know what is in your pipes, call the Middletown Water Department at 302-378-2211 about the lead service line inventory.

Questions Middletown homeowners ask
Why does my bathroom faucet drip after I turn it off?
A worn cartridge, washer or valve seat is the usual cause. The part no longer seals fully against the flow. Replacing it normally stops the drip.
Can I fix a leaking faucet myself?
Often yes, if the stop valves under the sink close fully and you can identify the faucet style. Turn off the water first and keep every small part in order. Call a plumber if the valves are stuck or corroded.
Is a leaking faucet an emergency?
A drip is not, but a spray or a wet cabinet is. Close the stop valve or the main shutoff and call. The 24/7 emergency line handles after-hours leaks that cannot wait.
Should I repair or replace the faucet?
Repair when parts are available and the finish is sound. Replace when parts are scarce, the body is pitted or leaks at several points.
What should I do after the plumber finishes in Middletown?
Run the tap for 30 seconds to 2 minutes before drinking from it if the water sat for hours, following the town water quality report. Also check the aerator for debris.
Do you handle faucet leaks in Townsend?
Yes, Townsend is about 7 miles south of Middletown on DE-71 and is served by the same dispatch line. See the Townsend plumbing page for details.
The short version
Find where the water shows up, close the stop valve, and take a photo. Those three habits save floors and settle most insurance questions, whether the cause is a worn O-ring or something larger.
For a repair or a replacement, call (410) 378-7601 and describe which part of the faucet is wet. The service area page lists the towns we dispatch to.
