Under-sink plumbing work by Mel One Maintenance in Melbourne

Before you callSend a wide photo and a close-up.

Include your suburb and tell us whether the problem is constant or only happens when a fixture is used.

What this service is for

Under-sink leaks are often discovered after the cabinet base has begun to swell. The cause may be a loose waste fitting, failed seal, cracked trap, worn hose, isolation valve or water tracking from the tap base; the source still needs to be checked rather than assumed from the wet area alone. The repair should address the connection that is actually failing.

What Mel One can help with

Kitchen sink waste and trap repairs
Bathroom vanity and basin pipework
Laundry trough connections
Flexible hose and isolation valve replacement enquiries
Dishwasher water and waste connection issues
Leak checks after repair or replacement

Questions customers often ask

Does your job sound like one of these?

You do not need technical terminology. Describe when the problem happens, where you see water and whether anything has already been repaired or replaced.

“The cabinet only gets wet when the sink drains. Can you replace the trap or waste seal?”

“Can you replace the flexi hoses and isolation valves under the vanity?”

“We installed a new sink and one connection is leaking. Can you correct it?”

A straightforward process

From your first photos to a completed, tested repair.

Send your suburb, a short description, one wide photo and useful close-ups.

We review the details and reply within 24 hours, then confirm whether we can help, access requirements and any likely parts.

The affected fitting or pipework is checked before repair and replacement options are explained.

Approved work is completed and the affected connection or fixture is tested.

Common questions

Useful answers before you enquire.

Why does it only leak when the sink drains?

That often points to the waste, trap or a seal rather than the pressurised supply. A site check is needed to confirm the source.

Can you replace the pipework inside the cabinet?

Yes, where replacement is the practical fix. Photos help confirm access, materials and the likely work before the plumber arrives.

Does this plumbing repair include the water-damaged cupboard?

Not automatically. The plumbing scope covers the pipe, fitting or connection work and checks after the repair. Repairing water-damaged cabinet board or joinery is a separate item, but you can describe both parts in the same enquiry so each scope can be confirmed.

What should I include for an under-sink repair quote?

Tell us your suburb, which sink or laundry trough is affected, how many connections need attention and whether water appears continuously or only during use. Mention previous repairs, access restrictions and any preferred timing. If available, attach a wide photo and a close-up through the quote form, or email them. The source, fitting condition, required parts and access need checking before the repair or replacement scope is confirmed. Include any cupboard damage in the same description so that separate work can be discussed; a reply does not confirm an arrival time.
