Sink leaks and drain problems we repair in Elgin
Water in the sink cabinet means something is loose, cracked or worn out: a trap nut, a strainer gasket, a dishwasher hose or the drain pipe in the wall. We find which one in your Elgin kitchen and repair it so the cabinet floor stays dry.
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.
Drip from the trap or slip joint
The nuts on a plastic or chrome trap seal with thin washers that wear, shift or crack. We replace the washers or the whole trap so the joints seal again.
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.
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.
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.
Leak only when water runs
A leak that appears when the faucet is on but stops when the sink drains is often at the faucet or the supply lines. We check those before the drain.
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.
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 resealStrainer removed, cleaned and reset with fresh putty or a new gasket.
- Dishwasher and disposal connectionsDishwasher hose rerouted with a high loop or air gap where needed.
- Drain pipe and wall connectionCracked or rusted pipe cut out and replaced back to sound pipe.
- Supply side checkWe look at the stops and faucet lines too, since they leak into the same cabinet.
- Cabinet floor repairDamaged sink base floor cut out and replaced once the plumbing is dry.
Repair options
Plumber's putty and gasketsPutty or rubber gaskets seal the strainer to the sink; stone sinks often need a putty that won't stain.
PVC traps and tailpiecesPlastic trap parts that don't rust and are easy to service later.
Basket strainersStainless or brass strainers matched to the sink, set in putty or with a gasket.
Dishwasher hose and air gapParts that keep the dishwasher draining one way, into the sink drain.
Chrome-plated brass trapsBrass with a chrome finish, a sturdier choice than thin chrome-plated steel.

Kitchen Sink Leak & Drain Repair questions from Elgin homeowners
Why does my sink leak after installing a dishwasher?
Usually the drain hose: a loose clamp, the knockout in the disposal left in place or a bad tailpiece connection.
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.
How do I tell if it's the drain or the faucet?
Supply leaks happen whenever the valves are open; drain leaks only happen when water goes down.
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.
Will tightening the nuts fix it?
Sometimes, briefly. If the washer is worn or the pipe is cracked, tightening won't hold and can crack plastic fittings.

Permits go through Community Development Department (Building permits), City of Elgin, 150 Dexter Court, phone 847-931-6001. When your scope needs one, we prepare the application and schedule the inspections.
