Overview
Leaks under sinks are often hidden until cabinetry and flooring are already affected. Targeted diagnosis helps distinguish waste leaks from pressurised feed leaks.
Under-sink leak triage
- Empty cabinet and dry standing water.
- Tighten only accessible hand-tight fittings.
- Isolate local valve if feed leak is active.
Common symptoms
- Cabinet base swelling
- Moisture around trap fittings
- Damp smell in kitchen unit
Why act quickly
Water damage can escalate within minutes - saturating floors, ceilings, and electrics. Early intervention significantly reduces repair costs and prevents structural damage.
Under-sink leak causes
- Trap connections loosening over time.
- Perished washers on tap tails.
- Hairline cracks in waste fittings.
Checks focused on sink cabinets
- Separate waste-side and supply-side leak paths.
- Inspect tap tails, isolators, and trap geometry.
- Verify watertight performance under use.

Under-sink leak FAQs
What happens when I call about leak under sink?
We ask about the issue, your location and urgency, then check whether an independent contractor may be available.
Can someone attend quickly?
Attendance depends on live availability, time of day, and demand. We do not guarantee response times.
What should I do immediately?
If it is safe to do so, isolate the water supply where relevant, keep clear of electrical risks, and call for guidance.
How are costs handled?
Costs are usually discussed directly between the customer and the independent contractor. We do not guarantee fixed prices unless clearly stated.
What if no contractor is available?
If suitable availability cannot be identified, we explain that clearly so you can decide next steps, including contacting another provider.
Preventing sink-cabinet leaks
- Do quick monthly cabinet moisture checks.
