Bathroom Waterproofing & Shower Repairs

Compliant waterproofing and expert leak repairs that protect your home from costly water damage.

Stop Leaks Before They Start

Our licensed waterproofers carry out full membrane waterproofing to AS 3740 standards on every renovation, and we also specialise in diagnosing and fixing leaks, failed grout and deteriorating seals in existing bathrooms before they cause structural damage.

Why Melbourne Homeowners Choose Us for Waterproofing & Shower Repairs

A leaking shower rarely announces itself early. By the time you notice discoloured ceilings below, bubbling paint, or a musty smell, water has often been tracking through subfloor, framing, or the ceiling of the room underneath for months. Fixing that damage later can cost many times more than fixing the waterproofing failure that caused it, which is why we treat waterproofing repairs as urgent, not routine maintenance to be scheduled whenever it suits.

All our waterproofing work is completed to Australian Standard AS 3740, the benchmark for wet area waterproofing in Australian homes, using licensed waterproofers rather than general labour. We diagnose the actual source of a leak — failed membrane, cracked grout, a faulty shower base, or poor fall to waste — rather than resealing over a problem that will simply reappear in six months and cost you twice.

Whether you need a full re-waterproofing after a failed inspection, a leaking shower base replaced, or preventative waterproofing before you retile, we provide a fixed-price quote after a free on-site assessment, and back every job with our 10-year workmanship warranty, giving you real protection against the same problem coming back.

Our Process

Free Assessment & Leak Diagnosis

We inspect the shower, check for moisture in adjoining walls or the ceiling below, and identify the actual cause of the leak, not just the visible symptom.

Scope & Fixed-Price Quote

We outline exactly what needs repairing or replacing, whether it's membrane, grout, silicone, or the shower base itself, and provide one fixed-price quote before work starts.

Removal & Preparation

We remove failed tiling, membrane, or fittings as needed to expose the affected area, checking substrate condition and drainage falls before re-waterproofing begins.

AS 3740-Compliant Waterproofing & Reinstatement

Our licensed waterproofers apply a compliant membrane system, then retile, reseal, or reinstall the shower base and screen to match your existing bathroom.

Testing & Warranty Handover

We flood-test the repaired area to confirm the leak is resolved, then hand over documentation and your 10-year workmanship warranty on the completed work.

Frequently Asked Questions

How much does shower waterproofing repair cost in Melbourne?

Minor leaking shower repairs, like resealing or a partial membrane fix, typically cost $1,500 to $4,000. A full waterproofing membrane replacement, including retiling, generally runs $4,000 to $8,000 depending on shower size and existing damage.

How do I know if my shower is leaking?

Common signs include discoloured or bubbling paint on ceilings below the bathroom, a musty smell, damp skirting boards, or visible mould around grout lines. If you notice any of these, it's worth getting the waterproofing assessed before the damage spreads.

What is AS 3740 and why does it matter?

AS 3740 is the Australian Standard for waterproofing wet areas in residential buildings. It sets minimum requirements for membrane coverage, falls to waste, and material compatibility. Non-compliant waterproofing can void insurance claims and cause repeat leaks, so we always work to this standard.

How long do waterproofing repairs take?

Minor repairs like resealing or spot membrane fixes can be completed in 1 to 2 days. A full waterproofing replacement, including tile removal and reinstatement, typically takes 3 to 7 days depending on the extent of the damage found.

Can you fix a leak without a full bathroom renovation?

In most cases, yes. If the issue is isolated to the shower area, we can repair the waterproofing and retile just that section without touching the rest of the bathroom. We always recommend the least disruptive fix that properly solves the problem.

Is waterproofing repair work covered by warranty?

Yes, all waterproofing and shower repair work is backed by our 10-year workmanship warranty. If a repaired area fails due to our workmanship within that period, we return and fix it at no charge to you.
