Bathroom Leak Repair Sydney
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.
Why we quote after inspection
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.
Where Bathrooms Leak Actually Come From
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.
Most common call-out
A bathroom leak is usually a path, not one visible crack
Water can enter at the shower, bath edge, vanity, toilet, floor waste or in-wall plumbing, then show somewhere completely different. We inspect the path before deciding whether the fix is epoxy regrouting, silicone replacement, plumbing referral or membrane work.
Leaking Shower or Screen
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.
Bath, Spa or Shower-over-Bath
Silicone joints at the bath–wall and bath–floor junctions perish quickly. Combined shower-over-bath setups multiply the wet-area joints under pressure.
Vanity, Sink or Tap Connections
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.
Toilet Base & Cistern
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.
Floor Waste & Tiled Bathroom Floor
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.
Hidden In-Wall Plumbing
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.
