Sink leaks and drain problems we repair in Naperville
We repair leaking kitchen sink drains in Naperville: new traps and tailpieces, resealed basket strainers, tightened or replaced dishwasher connections and cracked drain pipe cut out and replaced.
Leak at the drain in the wall
The joint where the sink drain meets the wall pipe can loosen or corrode. We rebuild it so the trap seals to sound pipe.
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.
Leak right after a new dishwasher install
If the sink cabinet got wet right after the dishwasher was put in, the drain connection is the first place we look.
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.
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.
Swollen or stained cabinet floor
If the sink base floor is warped and stained, it has been wet for a while. Once the plumbing is dry, the floor panel can be replaced and protected with a liner.
Old S-trap or wrong parts
Sinks hooked up with corrugated tubing or an S-trap tend to leak and smell. A properly sized P-trap fixes both.
What we check and fix

Kitchen Sink Leak & Drain Repair questions from Naperville homeowners
Will tightening the nuts fix it?
Overtightening is how many plastic traps crack. If a gentle snug doesn't stop it, the part needs replacing.
Why is my kitchen sink leaking underneath?
Most often a worn trap washer, a failed basket strainer seal, a loose dishwasher hose or a cracked drain pipe. Supply lines and the faucet can leak into the same cabinet.

Fill the bowl and let it sit; drips at the strainer show up then. Run the faucet with the stopper out to test the trap.
