When a waterproofing membrane fails, sealing over the surface won't fix it. SmartSealed carries out full re-waterproofing and re-tiling for Sydney bathrooms and balconies where the membrane beneath the tiles has broken down: tiles stripped, failed membrane removed, new membrane installed to Australian Standards, re-tiled and finished.

Not sure if you need waterproofing or sealing?
If your grout or seals have failed but the membrane beneath is intact, the fix is usually sealing or epoxy regrouting over existing tiles, with no tile removal needed. See:
When the membrane has genuinely failed, those fixes won't hold. That's when re-waterproofing and re-tiling is the right answer.
Re-waterproofing & re-tiling, when the membrane has failed
Some leaks can't be sealed from the surface because the waterproofing membrane beneath the tiles has broken down. For those jobs we carry out full re-waterproofing:
What's involved
Confirm the membrane is the cause: through leak detection, not guesswork
Strip the affected area: tiles and failed membrane removed
Install a new high-quality waterproofing membrane to Australian Standards
Re-tile and grout the area, finished with sealing at every joint
It's a bigger job than sealing, which is exactly why we only recommend it when it's genuinely needed. You'll always be told which repair your bathroom or balcony actually requires, with an upfront quote for each option.

Common questions
Before you ask.
How do I know if I need sealing or full re-waterproofing?
If the leak comes from failed grout, seals or minor tile damage, sealing fixes it at a fraction of the cost. If the membrane under the tiles has failed, re-waterproofing is the honest fix. Our assessment (and leak detection where needed) tells you which one you're dealing with before you spend anything.
How long does waterproofing last?
A properly installed membrane is a long-term fix, and sealed surfaces are protected for years. Regular checks of grout and seals keep any bathroom or balcony ahead of trouble.
Do you waterproof new bathrooms or only fix leaks?
Both. We install membranes in renovations and new wet areas, and repair failed waterproofing in existing ones.
How soon can the area be used?
Sealed areas: 24 hours. Re-waterproofed and re-tiled areas: we'll give you the timeframe in the quote, as it depends on the size of the area and curing times.
