Sink leaks and drain problems we repair in Hanover Park
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 Hanover Park dry everything, run water in stages to find the source and rebuild the part that failed.
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.
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.
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.
Cracked or corroded drain pipe
Old chrome traps rust through from inside and plastic pipe can crack where it was overtightened. The damaged section is cut out and replaced.
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.
Swollen or stained cabinet floor
Particleboard cabinet bottoms swell once they get wet. We fix the leak first, then repair or replace the floor of the cabinet.
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.

Kitchen Sink Leak & Drain Repair questions from Hanover Park homeowners
Can a leaking sink cause mold?
It can, if the leak goes on for weeks. We check the cabinet and wall for moisture during the repair.
Do I need to replace the whole drain?
Most repairs are one component. In older homes with rusted galvanized, we may recommend replacing more.
What affects the price of a sink leak repair?
Where the leak is, which parts fail, whether the wall or cabinet needs opening and the age of the pipe. We give a written, itemized estimate after the visit.
How long does it take to fix a sink leak?
Usually a short visit. Leaks inside the wall or old corroded pipe take longer.
Why is my kitchen sink leaking underneath?
Common causes: a trap joint, the seal at the drain opening, the dishwasher or disposal connection, or old pipe that has rusted through.
