Sink leaks and drain problems we repair in Warrenville
We repair leaking kitchen sink drains in Warrenville: new traps and tailpieces, resealed basket strainers, tightened or replaced dishwasher connections and cracked drain pipe cut out and replaced.
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.
Drip from the trap or slip joint
A slow drip from the curved pipe under the sink is usually a slip joint. Tightening helps for a while; new washers or a new trap fix it.
Cracked or corroded drain pipe
Rust spots, crusty buildup or a hairline crack on the drain mean the pipe is failing. Replacing it costs far less than a ruined cabinet.
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.
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.
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.
What the repair visit covers
- Dry and inspectEverything under the sink is cleared and wiped dry so we can see where water appears.
- Locate the leakWater run in stages: faucet, full bowl, disposal, dishwasher drain.

- Drain pipe and wall connectionThe trap adapter or drain arm at the wall rebuilt when it leaks.
- Supply side checkWe look at the stops and faucet lines too, since they leak into the same cabinet.

Kitchen Sink Leak & Drain Repair questions from Warrenville homeowners
How long does it take to fix a sink leak?
Often within one visit; replacing a cabinet floor adds time after the plumbing is done.
Do I need to replace the whole drain?
Most repairs are one component. In older homes with rusted galvanized, we may recommend replacing more.
Why is my kitchen sink leaking underneath?
Under-sink leaks usually come from slip joints, the strainer, the dishwasher connection or the pipe itself. We test each until we find it.

We can cut out the swollen bottom and install a new panel in the sink base.
