Sink leaks and drain problems we repair in Lombard
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 Lombard dry everything, run water in stages to find the source and rebuild the part that failed.
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.
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.
Drain sealed with tape or putty
Temporary patches hide the leak until it gets worse. A new fitting or pipe section is the real repair.
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.
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.
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 around the drain in the sink bowl
If the leak appears only after the bowl is filled, the seal between the strainer and the sink is gone. We pull the strainer, clean it and reseal it.

Kitchen Sink Leak & Drain Repair questions from Lombard 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.
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.
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.
Do I need to replace the whole drain?
Most repairs are one component. In older homes with rusted galvanized, we may recommend replacing more.
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.
Does Lombard require a licensed plumber for sink leak repair?
Registration requires a copy of a current State of Illinois Department of Public Health plumbing registration. Our plumbing connections are made by licensed plumbers.
Can you do sink leak repair in a Lombard condo?
Associations usually set rules for work hours, elevators, deliveries and insurance, and many require approval for plumbing, electrical or structural changes. We provide the certificate of insurance and follow the building's rules.
What is the Lombard building department phone number?
Permits go through Building Division, Community Development and Building, phone (630) 620-5750. When your scope needs one, we prepare the application and schedule the inspections.
Do I need a permit for sink leak repair in Lombard?
It depends on the scope. Lombard's rule in short: Village requires a building permit for new structures and updates to existing structures; replacing interior doors and fixtures at the same size with no structural change needs no permit. We handle the permit when one is needed with Building Division, Community Development and Building.
