Sink leaks and drain problems we repair in Downers Grove
A leak under the kitchen sink can come from a dozen joints, and the drip usually lands far from where it starts. Our licensed plumbers in Downers Grove dry everything, run water in stages to find the source and rebuild the part that failed.
Musty smell under the sink
If the sink base smells damp, water is getting somewhere. Finding a small leak early saves the cabinet and the floor below.
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.
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.
Drip from the trap or slip joint
A slow drip from the curved pipe under the sink is usually a slip joint. Tightening helps for a while; new washers or a new trap fix it.
Leak around the drain in the sink bowl
Water that shows up when the sink is full often comes from the basket strainer. The old putty or gasket has failed and the strainer is reset with fresh plumber's putty.
Old S-trap or wrong parts
Flexible accordion pipe, mismatched parts and S-traps all cause leaks and slow drains. We replace them with standard trap parts.
Dishwasher drain hose leaking
Leaks that show up only when the dishwasher drains are usually at the hose connection. We replace the clamp or the hose and set a proper high loop or air gap.

Is it safe to keep using the sink?
If water is pooling, stop using the sink and the dishwasher until we fix it.

We can cut out the swollen bottom and install a new panel in the sink base.
