Sink leaks and drain problems we repair in Northbrook
We repair leaking kitchen sink drains in Northbrook: new traps and tailpieces, resealed basket strainers, tightened or replaced dishwasher connections and cracked drain pipe cut out and replaced.
Swollen or stained cabinet floor
A long, slow leak turns the cabinet floor soft and dark. After the repair we can cut out the damaged panel and fit a new floor in the sink base.
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.
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.
Drip from the trap or slip joint
Slip-joint washers flatten and dry out over the years. When a trap keeps weeping no matter how hard you tighten it, the trap assembly is replaced.
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
If the sink base smells damp, water is getting somewhere. Finding a small leak early saves the cabinet and the floor below.
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.
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 resealStrainer removed, cleaned and reset with fresh putty or a new gasket.
- Trap and tailpieceNew trap, washers and tailpiece in PVC or chrome-plated brass.
- Dishwasher and disposal connectionsDishwasher hose rerouted with a high loop or air gap where needed.
- Drain pipe and wall connectionThe trap adapter or drain arm at the wall rebuilt when it leaks.
- Supply side checkShut-off valves and supply connectors checked while we are there.
- Cabinet floor repairNew cabinet bottom or a protective liner after the leak is fixed.
Parts we replace
Dishwasher hose and air gapA new drain hose, clamps and a high loop or counter air gap where required.
Basket strainersThe fitting at the bottom of the bowl that holds the stopper and seals the drain.
Transition couplingsFittings rated for connecting new drain pipe to older metal pipe.
PVC traps and tailpiecesPlastic trap parts that don't rust and are easy to service later.

Kitchen Sink Leak & Drain Repair questions from Northbrook homeowners
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.
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?
For a loose nut, maybe. For cracked pipe, wall connections or code issues like S-traps, call a licensed plumber.
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.
Do I need to replace the whole drain?
Rarely. Usually one part failed: a washer, a trap, a strainer seal or a section of pipe.
Does sink leak repair need a Northbrook building permit, and who files it?
Permits go through Development & Planning Services, phone 847-664-4050. When your scope needs one, we prepare the application and schedule the inspections.
