Sink leaks and drain problems we repair in St. Charles
Water in the sink cabinet means something is loose, cracked or worn out: a trap nut, a strainer gasket, a dishwasher hose or the drain pipe in the wall. We find which one in your St. Charles kitchen and repair it so the cabinet floor stays dry.
Leak around the drain in the sink bowl
The strainer sits in a bed of putty that dries and cracks over time. A fresh seal, or a new strainer if the old one is corroded, stops the leak at the drain opening.
Leaking garbage disposal connection
Disposals leak at the sink flange, the dishwasher inlet or the discharge pipe. Some are resealed; a disposal leaking from its body has to be replaced.
Leak at the drain in the wall
When the trap is dry but the back of the cabinet is wet, the leak can be at the trap adapter or the drain arm going into the wall.
Dishwasher drain hose leaking
The dishwasher hose connects under the sink at the disposal or a tailpiece branch. A loose clamp or a cracked hose end leaks every cycle.
Leak only when water runs
Water under the sink only while the faucet runs points to the supply side: a valve, a connector or the faucet base. Drain leaks show up when water goes down.
Cracked or corroded drain pipe
A pinhole or crack in the drain pipe can't be sealed for long. We replace the section with new pipe and fittings.
Drain sealed with tape or putty
If someone wrapped the pipe to stop a drip, the joint under the wrap is failing. We cut it out and rebuild it.
Where we look first
- Dry and inspectWe empty the cabinet, dry every pipe and look for corrosion, cracks and stains.
- Basket strainer resealA new basket strainer if the old one is corroded or cracked.
- Trap and tailpieceNew trap, washers and tailpiece in PVC or chrome-plated brass.
- Dishwasher and disposal connectionsHose clamps, inlet and outlet fittings checked and replaced.
- Drain pipe and wall connectionCracked or rusted pipe cut out and replaced back to sound pipe.
- Supply side checkWe look at the stops and faucet lines too, since they leak into the same cabinet.
- Leak testWe run water through every path and confirm nothing drips.

Kitchen Sink Leak & Drain Repair questions from St. Charles homeowners
Is it safe to keep using the sink?
With a small drip, put a bowl under it and use the sink lightly until it's repaired. A steady leak means stop using that drain.
Why does my sink leak after installing a dishwasher?
Look at the dishwasher drain fitting first. Improper hookups are a frequent cause right after an install.
How long does it take to fix a sink leak?
Usually a short visit. Leaks inside the wall or old corroded pipe take longer.
How do I tell if it's the drain or the faucet?
If it leaks only while the faucet runs, look at the supply side. If it leaks when water drains, it's the drain side.
Will tightening the nuts fix it?
Sometimes, briefly. If the washer is worn or the pipe is cracked, tightening won't hold and can crack plastic fittings.
