Sink leaks and drain problems we repair in Lisle
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 Lisle dry everything, run water in stages to find the source and rebuild the part that failed.
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.
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.
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.
Leaking garbage disposal connection
We check the mounting flange, the hose inlet and the outlet to find where a disposal is leaking before deciding what to replace.
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.
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.
Leak right after a new dishwasher install
A new dishwasher sometimes leaks at the drain connection because the knockout plug in the disposal wasn't removed or the clamp wasn't tightened. We correct the hookup.
Where we look first
- Dry and inspectWe empty the cabinet, dry every pipe and look for corrosion, cracks and stains.
- Locate the leakWe test each part separately until the drip shows up.
- Basket strainer resealA new basket strainer if the old one is corroded or cracked.

- Cabinet floor repairNew cabinet bottom or a protective liner after the leak is fixed.

Kitchen Sink Leak & Drain Repair questions from Lisle homeowners
Will tightening the nuts fix it?
A quarter turn may stop a drip, but recurring leaks mean new washers or a new trap.
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.
Can a handyman fix a leaky sink pipe?
Simple trap washer swaps are minor. Replacing drain pipe, wall connections or anything tied into the plumbing system is work for a licensed plumber in Illinois.
Why does my sink leak after installing a dishwasher?
The new hose connection is the likely culprit. We fix it and make sure there is a high loop or air gap.
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.
Do Lisle condo associations need to approve sink leak repair?
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 Lisle building department phone number?
Permits go through Development Services Department, phone 630-271-4150. When your scope needs one, we prepare the application and schedule the inspections.
