Whether the water is on the ceiling below, the wall beside, or the floor outside your bathroom — we find the actual source and fix it. Sydney specialists in bathroom leak detection and repair, covering showers, baths, vanities, toilets, floor wastes and hidden membrane failures.
Bathroom leaks have at least six common sources. A guessed price online either scares you off or sets the wrong expectation. We'd rather come on-site, find the actual source, and give you one written fixed-price quote.
Six common sources cover almost every bathroom leak we attend in Sydney. The visible symptom rarely matches the cause — which is why a proper diagnostic matters more than a guessed quote.
The most common source. Failed grout, perished perimeter silicone or a deteriorated screen seal lets water track behind tiles to the wall cavity, ceiling below, or skirting.
Silicone joints at the bath–wall and bath–floor junctions perish quickly. Combined shower-over-bath setups multiply the wet-area joints under pressure.
Sink wastes, mixer tap penetration seals and splashback silicone are small leaks that often go unnoticed until the cabinet base swells or the floor below stains.
Failed wax seals, hairline cistern cracks or a breached floor membrane around the pan all present as a small puddle that returns no matter how often you mop it.
When the bathroom floor membrane fails — at the floor waste, hob, or door threshold — water tracks under tiles and shows up in the room or apartment below.
Cracked supply lines or pinhole copper leaks behind tiles can mimic membrane failure. We rule in or out plumbing causes before any waterproofing scope is quoted.
Bathroom leaks are too variable for a self-serve quote — but a quick three-question diagnostic will narrow down the likely source, so your free inspection gets straight to the fix.
We'll show your likely leak source and recommended next step. No prices guessed — final scope and pricing are confirmed on-site at your free inspection.
