What this service solves
- Dripping faucets
- Leaks under the sink
- Low flow from a faucet
- Loose handles and spouts
- Cracked or chipped sinks
Common symptoms
- Drip from the spout
- Water around the faucet base
- Damp cabinet floor
- Handle that is stiff or loose
- Sprayer that leaks or has weak flow
Most likely causes
Worn cartridge or washer
Cartridges and washers wear out, causing drips from the spout.
O-ring failure
Worn O-rings cause leaks around the base of the spout.
Loose supply connections
Compression nuts and supply hoses can loosen or wear.
Drain leaks
Slip-joint washers on the trap or a failed basket strainer seal cause leaks under the sink.
Mineral buildup
Hard water clogs aerators and cartridges.
How the problem is diagnosed
- Identify faucet type (cartridge, ball, ceramic disc, compression)
- Check whether the leak is supply (constant) or drain (only when draining)
- Inspect shutoff valves
Repair and replacement options
| Option | Best for | What to know |
|---|---|---|
| Cartridge or washer replacement | Drips | Matching the cartridge to the brand and model is important. |
| Supply line and stop valve replacement | Under-sink supply leaks | Old multi-turn stops often fail when first used. |
| Drain reseal | Leaks only when draining | Replace washers or the basket strainer. |
| Faucet replacement | Corroded or obsolete faucets | Often more sensible than repair for old faucets without available parts. |

Specific faucet & sink repair services
Faucet & Sink Repair: common questions
Why is my faucet dripping?
Worn cartridges, washers or seals are the usual cause. The fix depends on the faucet type, so identifying the brand helps.
Why is there water under my sink?
If it leaks constantly, check supply lines and shutoff valves. If it leaks only when the sink drains, check the trap, drain connections and basket strainer.
Should I repair or replace an old faucet?
If parts are available and the body is in good condition, repair is reasonable. Corroded bodies, obsolete models or repeated leaks favor replacement.
