Waterproofing in Northcote runs into a problem you do not get in a newer suburb: a lot of the housing was built long before waterproofing was a regulated trade, and a good share of it sits under a heritage overlay. Northcote Hill has double-storey Victorian terraces, there are row houses and flats through the postcode 3070 area, and there are around eighteen off-the-plan developments adding a very different kind of building to the mix.
Those are three different waterproofing problems. This page explains what each one involves before it talks about hiring anyone.

Waterproofing a Northcote terrace
Victorian terraces were not built with membranes, and most terrace work we do here is bathroom waterproofing. When a bathroom in one of these has been renovated at some point over the last century, what is under the tiles is anyone’s guess until it comes up.
Two things make terrace work different. First, the substrates move: timber floors flex in a way concrete does not, and a system that cannot accommodate that will crack at the junctions. Second, terraces share walls. A shower leaking in one property does not stay in that property, and by the time it shows up next door the conversation has become expensive.
If you have a terrace with a bathroom that smells damp, or paint lifting on a shared wall, that is worth looking at before it becomes a structural repair rather than a waterproofing job.
Heritage overlays and external work
Heritage overlay is a live consideration when buying in this part of Darebin, and it affects waterproofing when the work touches the outside of the building: balconies, external walls and below-ground areas.
The practical effect is that some approaches available on an unrestricted property are not available here, and the work needs to be planned with that in mind rather than discovered mid-job. If your property is affected, tell us at the walkthrough and we will scope the work around it.
New developments and apartments
The off-the-plan buildings going up around Northcote are the opposite job: concrete substrates, designed falls, and balconies or podium areas that need to be right before anything is built over them.
For builders and developers, what matters is staging and the certificate. For owners in a newly completed building, the questions are usually about a balcony that is not draining properly or a wet area that was signed off but is showing signs it should not be.
Which system suits which building
We work with sheet membrane, liquid membrane, polyurethane and cementitious systems, and we screed where the fall is wrong.
Broadly: liquid systems detail well around awkward junctions and penetrations, which older buildings have a lot of. Sheet systems come pre-formed and suit large, regular areas. But the real decision is made from your substrate, your exposure and the manufacturer’s specification, not from a rule of thumb. Each system has its own service page if you want the full technical picture, starting with residential waterproofing.

What waterproofing costs in Northcote
This is the question everyone actually wants answered, so here is how it works.
We do not quote a rate per square metre without seeing the job. You send us the details, we come out for a free, no-obligation on-site walkthrough, and you get a clear quote and timeline with no hidden costs.
On Northcote’s older housing especially, the area being waterproofed is a poor predictor of price. What moves the number is preparation: whether the existing screed has to come up, whether the substrate has been wet long enough to need repair, whether the falls have to be rebuilt. A terrace bathroom that needs the floor taken back and re-screeded is a different job to one that needs a correctly specified system over sound preparation, even if they look identical.
The walkthrough is how you find out which one you have before committing to anything.
Compliance and your certificate
Waterproofing in Victoria is governed by Australian standards, and we work to them along with each manufacturer’s application recommendations. Where a job requires a waterproofing certificate, we provide it.
That certificate matters more than usual on older housing. In a terrace that has been renovated several times, it is often the only document that establishes when a wet area was last done properly and by whom.
How the job runs
Send us the details. We come out for a free on-site walkthrough and assess what the work genuinely requires. You get a clear quote and a timeline. Our licensed and insured team carries out the work using premium-grade materials, keeping the site clean and disruption low, which matters in a terrace where the bathroom is the only bathroom. We finish, often ahead of the predicted date, with guaranteed quality on the work.

It changes what a leak costs you. Water moving through a shared wall becomes your neighbour’s problem as well as yours, which is why we would rather look at a damp-smelling terrace bathroom early than after the frame has been wet for two years.
It can, where the work touches the outside of the building. Some approaches available on an unrestricted property are not available here. Tell us at the walkthrough if your property is affected and we will scope around it.
Sheet membranes are pre-formed and applied to the surface. Liquid membranes go on wet and cure in place, which makes them easier to detail around penetrations and junctions. Older Northcote housing has a lot of awkward junctions, so liquid systems often earn their place here.
On housing this old it matters more than usual, because a system that suits concrete may not tolerate a timber floor that moves. We decide it at the walkthrough and explain the reasoning.
It depends on the product’s cure time. We give you the real figure for your system rather than a convenient one, which matters in a terrace where the bathroom is the only bathroom.
