Sink leaks and drain problems we repair in Chicagoland
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 Chicagoland dry everything, run water in stages to find the source and rebuild the part that failed.
Leak right after a new dishwasher install
New installs leak most often at the hose clamp or the tailpiece fitting. We redo the connection and run a full cycle to check it.
Musty smell under the sink
A mildew smell in the cabinet often means a slow leak that never pools. We check every joint and look for moisture under the cabinet floor.
Leaking garbage disposal connection
Water from the disposal area may be a loose discharge tube or a failed flange seal. We tell you whether it's a repair or a new unit.
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
An S-shaped trap with no vent can siphon dry and let sewer odor into the kitchen. When we repair the drain, we bring it up to a vented P-trap where the setup allows.
Leak at the drain in the wall
Water behind the sink base often starts at the wall connection. We open what we need to reach it and replace the failed fitting.
Dishwasher drain hose leaking
A dishwasher hose without a high loop or air gap can push dirty water back into the machine. We fix the leak and the routing at the same visit.
What we check and fix
- Dry and inspectEverything under the sink is cleared and wiped dry so we can see where water appears.
- Basket strainer resealA new basket strainer if the old one is corroded or cracked.
- Trap and tailpieceThe trap assembly rebuilt with matching parts and a proper seal.
- 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 checkShut-off valves and supply connectors checked while we are there.
- Leak testWe run water through every path and confirm nothing drips.
Parts we replace
Transition couplingsShielded couplings and adapters to join new PVC to old galvanized or cast iron.
Dishwasher hose and air gapParts that keep the dishwasher draining one way, into the sink drain.

Chrome-plated brass trapsHeavier metal traps for exposed sinks or where you want a finished look.

Repair or replace? Common questions
Do I need to replace the whole drain?
Not usually. We replace what failed, unless the old metal drain is corroded throughout.
Is it safe to keep using the sink?
Small leaks can wait a day; ongoing water damages the cabinet and floor quickly. Shut off the valves if it's the supply side.
Can a leaking sink cause mold?
Yes. A slow leak that keeps the cabinet damp can grow mold on the cabinet floor and the wall behind it. Fixing the leak quickly is the best prevention.
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.
Can a handyman fix a leaky sink pipe?
For a loose nut, maybe. For cracked pipe, wall connections or code issues like S-traps, call a licensed plumber.
