Identifying the faucet type
Compression faucets with two handles use rubber washers that press on a seat; they drip when the washer wears. Single-handle faucets use ceramic cartridges or ball assemblies. Cartridges differ by brand and even by model year, so knowing the make helps us bring the right part. Look for a logo on the handle, escutcheon or spout.
Typical repair
- Close the angle stops below and open the tap to bleed pressure.
- Remove the handle and bonnet nut, pull the cartridge or stem.
- Inspect the seat and body for scale or pitting.
- Fit a new cartridge or washer and O-rings, grease where the maker specifies.
- Reassemble, restore water and check for drips, handle stiffness and leaks under the deck.
Leaks you cannot see
A leak under the sink is often the faucet's supply hoses or the pull-down spray hose rubbing against the drain. Braided connectors past roughly a decade should be swapped. Water around the base of a kitchen faucet usually means a failing O-ring on the spout.
If the angle stops are frozen solid or leak when you turn them, we can replace them during the visit. A working valve is what makes the next repair quick.
When to replace instead
If the body is cracked, parts are discontinued or the finish has failed, a new faucet makes sense. See faucet installation.

Quick answers
Is one drip really worth a visit?
It is. Drips waste water, can stain the sink and often gets worse quickly.
