Leak Under Kitchen Sink: Immediate Steps & 24/7 Emergency Response

A leak under the kitchen sink requires fast action. Here’s what to do immediately and how our 24/7 emergency engineers can stop it before it causes major damage.

Act Fast: Your First Steps When You Spot the Leak

Discovering a leak under your kitchen sink is a call for immediate action. Water damage escalates quickly, warping cabinetry, damaging floors, and promoting mould. The moment you see water, your priority is to stop the flow. First, clear out everything from under the sink. Get those cleaning supplies and bins out of the way so you can see the source. Next, turn off the water supply. Look for the small shut-off valves on the pipes leading to the hot and cold taps. Turn them clockwise until they stop. If you can’t find them or they’re stuck, you may need to shut off the main household water stopcock.

Now, contain the existing water. Use old towels, a mop, or a wet-dry vacuum if you have one. The goal is to get the area as dry as possible, as fast as possible. This isn’t a permanent fix, but it’s critical damage control while you arrange a professional repair. Do not ignore a persistent drip or a small pool of water. What seems minor can be a sign of a bigger issue hidden within the pipework or waste system.

Why You Need a Professional Leak Detection Engineer

While you might see water dripping from a tap connector, the true source can be elusive. Leaks often travel along pipes and drip far from their origin. A DIY diagnosis can miss a cracked pipe behind the cabinet, a failing seal on the waste trap, or a problem with the dishwasher connection. Our engineers are trained in precise leak detection, using specialist equipment like moisture meters and acoustic listening devices to pinpoint the exact location of the leak without unnecessary guesswork or damage to your property.

Attempting a temporary fix with tape or sealant rarely holds and often worsens the problem by allowing water to seep into surrounding materials. A proper repair requires identifying the compromised component—be it a washer, valve, pipe section, or trap—and replacing it correctly. Our emergency response isn't just about stopping the water today; it's about implementing a reliable, lasting solution that prevents a recurrence and the costly structural damage that follows.

We work swiftly and cleanly, resolving the issue and advising on any necessary follow-up, such as cabinetry drying, to ensure your kitchen is safe and functional. Don’t let a small leak turn into a major renovation project. Immediate professional intervention is the most effective way to protect your home.

Frequently asked questions

1

Should I try to fix a kitchen sink leak myself?

We strongly advise against DIY repairs for leaks. Temporary fixes often fail and can hide the true source, allowing water damage to spread unseen within cabinetry and floors. Incorrect repairs can also lead to more severe flooding. Our engineers accurately diagnose and permanently resolve the issue.

2

How quickly can you respond to an emergency leak call?

We operate a 24/7 emergency response service. When you call, we immediately dispatch an engineer. Our goal is to have a specialist on site as fast as possible to stop the leak and prevent further damage, any time of day or night.

3

What causes leaks under the kitchen sink?

Common causes include loose or corroded connections on supply lines, worn tap washers, cracked plastic pipes, blocked or leaking waste traps (the U-bend), and failed seals on dishwasher or washing machine inlet hoses. Our engineers use detection equipment to find the exact cause quickly.
