Perth's Balcony Waterproofing Specialists
An exposed balcony takes everything Perth's weather throws at it — baking summer sun, driving winter rain and constant expansion and movement. Over time the original waterproof membrane breaks down, grout cracks and water starts finding its way into the structure below.
AllSealedWA has sealed showers, bathrooms, balconies and rooftops across Perth for over 15 years. We diagnose exactly where a balcony is leaking, then apply the right waterproof membrane system for the surface — so the fix lasts, rather than papering over the problem. Every job starts with a clear, written, obligation-free quote.

Warning signs
Signs Your Balcony Needs Waterproofing
A leaking balcony rarely shows itself on top — the first clues usually appear in the room or on the ceiling below. Notice any of these? It's worth booking a leak-detection check.
Stains on the Ceiling Below
Water stains or bubbling paint on the ceiling or wall of the room directly beneath the balcony.
Water Pooling After Rain
Water that sits on the surface instead of draining away points to failed falls or blocked drainage.
White, Chalky Efflorescence
A white, powdery residue on the tiles or grout is a classic sign water is moving through the slab.
Lifting or Drummy Tiles
Tiles that lift, move or sound hollow when tapped often mean water has got in beneath them.
Cracked or Crumbling Grout
Cracked, missing or crumbling grout lets water track straight down into the structure.
Damp or Rust Underneath
Damp patches, rust marks or crumbling concrete on the underside of the balcony slab.

What Proper Balcony Waterproofing Actually Involves
A balcony looks like a simple tiled surface, but underneath the tiles sits the part that really matters: the waterproof membrane. That membrane is a thin, continuous layer of watertight material that stops water reaching the structure below. When it fails, the tiles and grout on top can look perfectly fine while water quietly tracks into ceilings, walls and framing.
That's why a lasting fix is about more than fresh grout. External, above-ground waterproofing in Australia is governed by Australian Standards (AS 4654), which set out how membranes should be selected, detailed at edges and drains, and protected. We apply membranes the way they're meant to be applied — correctly prepared, correctly detailed and given time to cure — so the balcony performs for years, not months.
Depending on the balcony's condition, we can re-waterproof by lifting the existing tiles, or work with membrane systems suited to the specific surface and exposure. If you're weighing up your options, our guides on preventing water damage from leaking balconies and what a balcony repair typically costs are a good place to start.
Not sure whether your balcony needs re-waterproofing or just a repair? Book an electronic leak-detection test — call 1300 884 117 and we'll pinpoint the problem first.

How it works
How We Waterproof Your Balcony
A clear, no-surprises process from first inspection to a sealed, finished balcony.
01
Inspect & Leak-Detect
We assess the balcony and use electronic water detection to trace exactly where water is getting through, then explain what we find.
02
Prepare the Surface
Tiles, failed grout or old coatings are dealt with as needed and the surface is cleaned and primed — sound prep is what a membrane relies on.
03
Apply the Membrane
The right waterproof membrane is applied and detailed at edges, junctions and drains, then left to cure properly before anything goes over it.
04
Finish & Test
We retile, regrout and reseal as required, leave the site clean, and make sure the balcony is watertight before we call it done.

What it costs
How Much does Balcony Waterproofing Cost in Perth?
There's no one-size-fits-all price for balcony waterproofing — a targeted repair is a very different job to lifting the tiles, re-waterproofing the whole slab and re-tiling. Rather than quote a number that turns out to be wrong, we inspect the balcony first (often with an electronic leak-detection test), then put an exact, itemised price in writing. Here's what shapes that quote:
- Size & Layout — a larger balcony with more edges, drains and penetrations needs more membrane and detailing.
- Repair vs Full Re-Waterproof — a targeted repair costs far less than lifting the tiles and re-waterproofing the whole slab.
- Condition & Extent of Damage — how far water has already tracked, and whether tiles, screed or the slab need attention.
- Access & Height — an upper-level or hard-to-reach balcony can add to preparation and set-up.
- Tiles & Finishes — your tile and finish choices feed into the final figure.

Balcony Waterproofing Questions, Answered
How do I know my balcony needs waterproofing?
The clearest warning sign is water staining or bubbling paint on the ceiling or wall directly below the balcony. On the balcony itself, look for water pooling after rain, a white chalky residue (efflorescence) on the tiles or grout, lifting or drummy tiles, cracked and crumbling grout, or a musty smell. Any of these suggests the membrane below the tiles is no longer doing its job. An electronic leak-detection test confirms where the water is getting in.
Do you have to remove the tiles to waterproof a balcony?
Not always. Depending on the balcony's age, exposure and condition, we can re-waterproof by lifting the existing tiles to apply a new membrane, or use membrane systems suited to working with the current surface. We assess the balcony first, then recommend the approach that will actually last for your situation and explain the reasoning before you commit.
How much does balcony waterproofing cost in Perth?
It depends on the size of the balcony, its condition, how it's accessed and whether tiles need to be lifted and replaced. Because those factors vary so much from balcony to balcony, we provide an obligation-free written quote after inspecting the area — often alongside an electronic leak-detection test — so the price reflects the real scope of work rather than a rough guess.
What causes balconies to leak in the first place?
Most balcony leaks come down to a failed or ageing waterproof membrane, made worse by Perth's harsh sun, heavy seasonal rain and the constant expansion and movement an exposed surface goes through. Cracked grout, perished silicone and poor drainage all give water a path in, and once it reaches the structure below it can cause real damage. Fixing the surface without addressing the membrane usually only delays the problem.
How long does a waterproof membrane last?
A membrane that's correctly selected, applied and protected by sound tiling and grout can perform for many years. The key words are "correctly applied" — waterproofing is a fine art that needs the right product, proper surface preparation, careful detailing at edges and drains, and enough time to cure. That's exactly why our technicians are trained specifically in membrane application.
How long does the job take?
Most residential balconies are completed within a few days, but the exact timeframe depends on the size, the condition of the existing surface, whether tiles are being lifted and replaced, and curing time for the membrane and grout. We'll give you a realistic timeline as part of your written quote so you know what to expect before we start.
