All services

Waterproofing in Perth, from leaking showers to damp walls

Waterproofing in Perth covers more than the shower recess. It includes whole bathrooms, balconies over living rooms, basements set into sand, retaining walls holding soil against the house and rendered walls that let winter rain through. If water is getting where it should not, or a renovation needs a membrane, this is a good place to start.

You do not need to know the cause. Stained ceilings below a bathroom, loose tiles, musty smells, flaking paint or puddles at the base of a wall are enough to go on. Just note what you are seeing and where in the home it shows up.

How it works

From enquiry to finished job

1

Spot the problem or plan the project

Note what you are seeing, such as a stained ceiling, loose tiles or a damp wall, or the renovation you have planned and which room or area it involves.

2

Send one enquiry

Use the form to share the problem or project, the part of the home and your suburb. A short description is plenty.

3

Talk it through

If the job suits, a licensed and insured local contractor can follow up to ask questions or arrange to inspect the area.

4

Compare and decide

Check the scope, membrane and paperwork in any quote against the guides here before you sign. Whether to go ahead is entirely your decision.

Before you choose

A few plain facts make it easier to sort out the problem, compare quotes and decide who does the work on your Perth home.

No diagnosis needed

Leaks often show up a room or two away from where the water gets in. You only need to say what you have noticed and where, and a contractor can work out the cause on site.

Every type of home job

Bathrooms, showers, leaking shower repairs, balconies, basements, retaining walls and exterior walls are all covered, so one place handles whatever is letting water through.

Licensed and insured contractors

The work itself is carried out by licensed and insured local waterproofing contractors who know Perth homes, from limestone and brick to rendered double brick.

Help comparing quotes

Check that each quote names the membrane, the areas it treats, falls and waterstops for showers, flood testing before tiling and the paperwork you receive at the end.

Your payment protections

For a contract covered by the Home Building Contracts Act, you should get the Notice for the Home Owner before signing, the deposit is capped at 6.5% and defects you report in writing within four months of practical completion are fixed free.

Common questions

Waterproofing questions, Perth WA

Still have a question? Send it with your enquiry.

+ What affects the price of waterproofing a Perth home?

The price depends on the area, access, whether old tiles and membrane must come off and any repairs found underneath, so no fair figure can be given unseen. In WA, a contract covered by the Home Building Contracts Act caps the deposit at 6.5%, with later payments only for work done or materials supplied.

+ Does Perth's winter rain slow down a waterproofing job?

It can, for outdoor work. Balconies, retaining walls and external walls need dry surfaces for the membrane to go on and cure, so wet Perth winter days can push those jobs out. Indoor bathroom and shower work is less affected, though each coat still needs curing before tiles go down.

+ Will a balcony membrane in Perth need recoating?

Exposed outdoor surfaces usually need attention before indoor wet areas do. Perth balconies and walls face long, hot, dry summers and then heavy winter rain, which works on sealants, grout and coatings. A membrane hidden under sound tiles in a bathroom generally is not reapplied unless something fails.

+ Should waterproofing in an older Perth bathroom be replaced at the ten-year mark?

No, age alone is not the trigger. Many Perth homes have bathrooms built well before current membrane standards, but the signs matter more than the date: loose tiles, stained ceilings or skirting, mould or a musty smell. If you are renovating, new work has to meet current NCC requirements.

+ What upkeep helps waterproofing last longer in a Perth home?

Regular upkeep does help. Keep balcony and courtyard drains clear of the sand and leaves Perth gardens shed, so water cannot pond on the membrane through winter. Inside, repair cracked grout and failed silicone promptly, and check that water drains away behind retaining walls rather than building up against the house.
