Shower Leak Detection in Sydney

A leaking shower is the most common wet-area leak we trace. We pinpoint where water is escaping the recess — the membrane, the grout or a fitting — before a single tile is lifted.

Shower leak detection

A shower leak rarely stays in the shower

By the time you see a stain in the next room or the ceiling below, a shower has usually been leaking for a while. The water escapes the recess and tracks through the floor and walls out of sight.

We find exactly where it’s getting out — the waterproofing membrane, the grout and silicone, the hob, or a fitting — so the right repair is done once.

The problem

Signs your shower is leaking

A couple of these together is worth a look before the damage spreads.

Stains in the next room

Damp, discolouration or bubbling paint on a wall or floor backing onto the shower.

A mark on the ceiling below

A spreading stain under an upstairs shower is a classic sign.

Drummy or loose tiles

Tiles that sound hollow or lift point to moisture behind them.

Mouldy, crumbling grout

Grout and silicone that keep going mouldy or falling out.

White salty deposits

Efflorescence — chalky white marks — where water is wicking through.

A musty bathroom

A damp smell that lingers even when the room is dry.

What’s behind it

What’s usually behind it

A shower leak almost always comes back to one of these.

  • A failed or aged waterproofing membrane under the tiles.
  • Cracked grout or perished silicone at the joints and corners.
  • A leaking hob, screed or poor fall letting water pool.
  • A failed or loose fitting — mixer, outlet or floor waste.
  • Movement that has opened a junction in the recess.
How we find it

We find it before we open anything

The whole point is to confirm the exact failure point before any tile comes up.

  • Moisture map the recess — we read where water is sitting in the walls and floor.
  • Image behind the tiles — thermal imaging shows the wet area you can’t see.
  • Test to confirm — targeted testing proves the exact point water is escaping.
  • Explain and document — a clear result, with a report for strata or insurance if needed.

Shower leak detection — FAQs

Can you find the leak without removing the tiles?
Yes — in most cases. We lead with moisture mapping and thermal imaging, so the recess stays intact while we pinpoint the source.
Do you re-waterproof the shower?
We’re the detection step — we find and prove the failure point, then explain exactly what the repair involves so it’s fixed properly.
How long does it take?
Most shower inspections take one to two hours on site.
How much does it cost?
Our first hour on site is $299 inc GST, confirmed as a fixed price before we start.
