Leaking Shower Repairs Sydney

Water through the wall, a stain on the ceiling below, or swollen skirting next to the shower? We find exactly where the leak is coming from and fix it, from a worn mixer to a broken pipe in the wall or a failed shower waste.

No surprise bills: $0 call-out and a fixed price before any work starts.

Our guarantee: 12 months on our workmanship, in writing. What it covers

A leaking shower can be the mixer, the pipes inside the wall, the shower waste in the floor, or the waterproofing under the tiles. Guessing gets expensive, so we find the actual source first, then fix it. We replace leaking mixers and cartridges, repair or replace leaking pipes in the wall, and replace shower wastes and puddle flanges. Where the waterproofing has failed, we organise the waterproofer and tiler we work with. We can also write a plumbing report for your insurance claim.

Damp patches on the wall behind the shower, or water marks on the ceiling of the room below.

Timber next to the shower swelling, lifting or going soft.

Tiles that sound hollow or move, or grout that stays dark and mouldy, can mean water is getting behind them.

A shower that keeps dripping after it's turned off usually means a worn cartridge or washer in the mixer.

Worn cartridges and seals leak, sometimes into the wall cavity behind the mixer where you can't see it.

A cracked or loose joint on the hot or cold pipes in the wall can leak every time the shower is used.

If the waste or the flange around it has failed, water gets under the floor instead of down the drain.

If the membrane under the tiles has failed, water gets through even when the plumbing is fine. That's a job for the waterproofer and tiler we work with.

Common Questions

We test each part in turn: the mixer, the pipes in the wall, the shower waste and the waterproofing. That way we fix the actual cause, not just the symptom.

Yes, we organise it. Where the waterproofing has failed, we bring in the waterproofer and tiler we work with, so you deal with one company.

Yes. We can write a plumbing report on what caused the leak and what we found.

Usually it's a worn cartridge or washer in the mixer. It's a common, straightforward repair.

Stop using that shower and call us. Turn off the water at the meter if it's coming through quickly.

It depends on what's leaking. We find the cause first and give you a fixed price before we start, with a $0 call-out fee.
