Leak Detection & Repairs

Leak Detection and Repairs in Banora Point & the Tweed

Finding hidden leaks in walls, floors and underground pipes.

A leak you can't see can be more damaging than one you can. Water escaping inside a wall, under a slab or along an underground service line can quietly raise your bill, weaken building materials and encourage mould.

A4plumbing tracks down leaks methodically — starting with simple meter tests and visual checks, then narrowing down the location before opening anything up. Once found, we repair the pipe or fitting and explain how to avoid it happening again.

How the job works

  1. 1

    Meter test

    We confirm whether there's a leak and roughly how much water is being lost.

  2. 2

    Isolate sections

    By closing valves and checking fixtures, we narrow the leak to a zone of the property.

  3. 3

    Pinpoint

    Visual inspection, moisture checks and other suitable methods help locate the leak with minimal disruption.

  4. 4

    Repair

    We repair or replace the damaged section and retest the system.

What affects the cost?

Every job is different, so we don't publish fixed prices. We'll explain the costs before work begins. Factors include:

  • Where the leak is (accessible pipe vs under a slab)
  • Pipe material and age
  • Making good after access (tiling, plastering) — usually by other trades
  • Whether rerouting is better than repairing

Prevention and maintenance tips

  • Check your water meter overnight every few months
  • Replace braided flexible hoses every 5–10 years or at signs of rust or fraying
  • Don't ignore damp smells in wet areas

Questions customers ask

How can I check for a leak myself?

Turn off every tap and appliance, note the meter reading, wait an hour without using water and check again. Any movement suggests a leak.

Will you need to break tiles or walls?

We try to narrow the location first so any access opening is as small as possible. We'll discuss this with you before cutting into anything.

Can a leaking shower be fixed without a full renovation?

Sometimes. It depends on whether the leak is in the pipework, the waste, the grout or the waterproofing membrane. We'll tell you which and what the realistic options are.
