The short answer
Common Causes
Most faucet leaks trace back to a few internal parts. A worn-out washer or O-ring is the usual culprit, especially in older compression faucets. These rubber pieces degrade over time and no longer create a watertight seal, allowing water to seep out around the handle or spout.
For ball or cartridge faucets, a damaged cartridge can cause leaks. Mineral deposits from hard water can also build up inside the faucet, preventing parts from moving smoothly. Loose packing nuts or a corroded valve seat are additional possibilities. Identifying the exact leak point helps narrow down the cause.
Leak Location Matters
A leak from the spout while the faucet is off usually points to a worn washer or cartridge. A leak around the base or handle often means an O-ring or packing nut needs tightening. Dripping from the spout when the faucet is on could indicate a damaged aerator or internal blockage.
Take note of whether the leak happens only when the faucet is running or all the time. Also check if the leak worsens with water pressure changes. This information helps you describe the problem clearly to a plumber or a local water damage pro if the leak has caused any water damage.
- Leak at spout when off: worn washer or cartridge
- Leak around handle: loose packing nut or O-ring
- Leak at base: O-ring or seal failure
- Spray from aerator: mineral buildup or clog
- Leak under sink: supply line or connection issue
Quick Checks You Can Do
Before calling for help, you can do a few simple checks. Turn off the water supply to the faucet, usually via shutoff valves under the sink. Then inspect visible parts for obvious wear or looseness. Tightening a packing nut or replacing an aerator might solve a minor leak.
If the leak persists, you may need to replace internal parts. Kits with washers, O-rings, and cartridges are available at hardware stores. Follow the manufacturer's instructions for your faucet model. If you are unsure about the repair, a plumber can handle it. For any water damage that has already occurred, water damage pros can help with cleanup and drying.
When to Call a Pro
Some leaks are easy fixes, but others signal a deeper problem. If the leak is behind the wall or under the floor, you might have a hidden pipe issue. A persistent leak that you cannot stop could lead to water damage, mold, or structural problems. In such cases, professional help is wise.
A plumber can repair or replace the faucet and address any supply line issues. If water has soaked into cabinets, drywall, or flooring, water damage pros can extract water, dry the area, and prevent mold. They can also assess the extent of the damage and guide you on next steps. Acting quickly minimizes damage and repair costs.
Preventing Future Leaks
Regular maintenance can extend the life of your faucet. Clean aerators periodically to remove mineral buildup. Replace washers and O-rings at the first sign of wear. Avoid overtightening handles, which can damage seals. Fixing small drips promptly prevents bigger problems.
In areas with hard water, consider installing a water softener or using a descaling solution. Also, know where your main shutoff valve is located, so you can stop water flow quickly in an emergency. If you live in Rowlett, keep the shutoff valve location written down for quick access. These simple steps help keep your faucets working well.

Why does my faucet leak only when it's cold outside?
A leak that appears only in cold weather might be due to a frozen pipe causing pressure buildup. The ice expands and can crack fittings or seals. Once the pipe thaws, the leak becomes noticeable. Insulating pipes and keeping a slow drip during freezing temperatures can help.
Can I fix a leaking faucet myself?
You can fix many faucet leaks with basic tools and a repair kit. Turn off the water supply, disassemble the handle, and replace the worn washer or cartridge. Follow the manufacturer's instructions. If the leak persists or you are uncomfortable, a plumber can do the repair.
What should I do if the faucet leak caused water damage?
If water has damaged your cabinets, flooring, or walls, dry the area quickly to prevent mold. Remove standing water with towels or a wet vacuum. Use fans or dehumidifiers to speed drying. For extensive damage, contact the pros who can extract water and dry the structure properly.
