Waterproofing is the stage of a renovation nobody sees once the tiles go down, but it’s what protects the rest of the home from water damage for years afterward. Every waterproofing job — bathroom, laundry or another wet area — is carried out under a current licence, to AS 3740, with a compliance certificate provided before tiling begins. Because we also provide tiling services across Melbourne, we can coordinate the waterproofing and tiling stages as part of the same renovation.
Where water is getting through failed grout or silicone rather than the membrane itself, shower regrouting and resiliconing can stop it at the source without a full retile.
Bathroom waterproofing Melbourne homeowners can rely on — shower waterproofing, floor and required wall areas waterproofed to AS 3740 as part of a bathroom refurbishment.
We assess the wet area and confirm what needs to be waterproofed.
AS3740 waterproofing is the Australian Standard covering how floors, walls and junctions in bathrooms and laundries are waterproofed across Victorian wet areas. A waterproofing certificate confirms the work was carried out to that standard, and is generally required before tiling proceeds and for future building or insurance purposes.
The waterproofing membrane is what actually stops water getting through — applied in coats across the floor, up the walls to the required height, and across every junction and penetration where water could otherwise find a way in. Each coat needs time to cure before the next stage begins, which is why waterproofing sits on the critical path of a renovation timeline rather than being something to rush.
Waterproofing cost in Melbourne depends on the size of the area, the number of wet areas involved, and whether a compliance inspection is required. Below is an indicative breakdown for a bathroom wet area — your actual quote is itemised for your specific job after a site assessment.
These are indicative figures for a standard single wet area. Cost increases with additional wet areas (such as a laundry) or larger floor plans. Your itemised quote reflects your specific job.
| Waterproofing — shower, floor and required wall areas | $600 |
| Waterproofing inspection — where required, before covering | $150 |

The application itself is usually completed within a day for a standard wet area, but the membrane then needs time to cure before tiling can begin — typically at least 24 hours per coat, depending on the product used. This curing time is factored into your renovation timeline rather than being a separate delay.
Older Melbourne homes often have wet areas that were waterproofed to a lower standard than what’s required today, which is one of the most common issues we find during a renovation. Our waterproofing services across Melbourne regularly take us into Richmond, St Kilda, Brunswick and Brighton, checking the existing membrane, falls and junctions on site before scoping the work. New wet areas added as part of a home extension Melbourne project need the same compliant waterproofing as an existing bathroom or laundry.

Yes. Waterproofing in Victorian wet areas must comply with AS 3740, and a compliance certificate is required before tiling proceeds. We provide this certificate on completion of every job.
In Victoria, owner-builders can carry out waterproofing themselves below a certain project cost threshold, but it still needs to meet AS 3740 and be certified correctly. Given how much rides on it being done right, most homeowners engage a licensed waterproofer.
Cost depends on the size of the area, the number of wet areas involved, and whether a compliance inspection is required. We provide an itemised quote after a site assessment.
Membrane curing time depends on the product and the number of coats applied, typically requiring at least 24 hours per coat before the next stage. We factor this into your renovation timeline.
This depends on the membrane system and the specific areas being waterproofed, which is assessed as part of the job to meet AS 3740 requirements.
Yes, laundries are classified as a wet area under AS 3740 and need to be waterproofed the same way a bathroom does. We carry out waterproofing for both bathrooms and laundries.
The certificate itself doesn't expire, but it reflects the condition of the membrane at the time it was installed. It's a record of compliant work at that point, not an ongoing guarantee on its own — that's what the warranty is for.
