Failed Grout Letting Water Through, Sealed at the Source
This shower was losing water through cracked, worn grout lines and perished silicone. We removed the failed material, rebuilt the joints with waterproof epoxy grout and resealed the edges, so the water stays in the shower where it belongs.
A Shower Base That Leaked at the Edges, Resealed and Watertight
The silicone around this shower base had split along the edges, the classic path for water to escape into the wall and the floor. We stripped the old sealant, cleaned the joint and resealed it with silicone made for wet areas.
Left alone, a leak like these keeps tracking behind the tiles. Timber framing can start to rot out of sight, plaster swells and paint bubbles, and in apartments the water can reach the ceiling of the unit below. If the grout in your shower has gone soft and chalky, or the silicone has split along the edges, the time to fix it is before the damage spreads. When the whole shower needs rebuilding at the joints, see our shower regrouting service.
Know the Signs
Signs Your Shower May Be Leaking
A leak often shows up away from the shower first. Look for these signs.
Stains or bubbling paint on the wall behind the shower
Paint blisters and plaster swells when water gets behind the tiles and into the wall.
What a leak can damage →A damp or musty smell in the bathroom or next room
A musty odour that cleaning never shifts usually means damp materials behind the tiles or under the floor.
Where the water comes from →A wet patch, swollen skirting, damp carpet or a lifting floor near the bathroom
Water escaping the shower often shows first beside the bathroom: damp carpet at the ensuite entry, swollen skirting boards and rusting door frames.
What to do right now →A stain or drip on the ceiling below the shower
In double storey homes and apartments, a shower leak often announces itself on the ceiling underneath.
Leaks in rentals and apartments →Cracked, crumbling or chalky grout, or black or peeling silicone
Cement grout that has weathered soft and powdery no longer seals the joints, so every shower pushes water through.
Shower regrouting →Tiles that sound hollow or feel loose
Hollow sounding tiles can mean water has been getting underneath and breaking the bond.
Small tiling jobs →One sign is worth checking. Two or more together mean water is probably getting out.
Where Is the Water Coming From?
Not every leak is a grout leak. Here is how the common sources compare and who fixes each one.
| Source | What it looks like | Who fixes it |
|---|---|---|
| Grout and silicone at the tile surface | Cracked grout, grout gone soft and chalky, black or peeling silicone, damp near corners and the floor junction | Groutix |
| Waterproofing membrane under the tiles | Damp walls or ceiling below with grout that looks fine, repeated leaks after regrouting | We assess it. Usually needs more than a regrout, and we tell you before work starts |
| Shower base, screen or waste junction | Water at the base, around the drain or under the screen | We repair sealing and joint failures. Other faults are referred |
| Pipes, mixer or fittings behind the wall | Water that keeps flowing when the shower is off, wet wall around the tap | Licensed plumber |
Honest assessment, every time
A shower is only as watertight as its weakest junction, which is why we check the corners, the floor junction and the screen seals, not just the grout lines. Plumbing work in Victoria must be done by a licensed plumber. If we suspect a pipe leak, we say so and do not charge for a repair that will not fix it.
What a Leaking Shower Can Damage
Water behind tiles can travel a long way before you see it. A small leak can turn into a big repair.
Walls and plasterboard
Swelling, bubbling paint, crumbling lining
Timber framing and floor
Rot can start out of sight while water tracks behind the tiles
Ceiling and rooms below
Stains, drips and damage to the unit or room underneath
Mould and odours
Damp areas can keep growing mould
Covering the problem with sealer or fresh silicone only hides it for a short time.
Melbourne Homes
Why Melbourne Homes Leak the Way They Do
The housing stock here decides how a shower leak shows up. Melbourne's changeable weather works the joints open over the years, and then the damage follows the way the home was built.
Timber framed and weatherboard homes
Common across the inner west and north. Water behind the tiles rots timber framing and skirting boards out of sight, and the damp becomes a breeding ground for mould.
Brick veneer family homes
The post war and 1970s brick homes of the outer east and south east often show the leak as bubbling paint on the bedroom or hallway wall behind the shower, long before the grout looks bad.
Apartments and double storey homes
Here the first sign is usually downstairs: a stain spreading on the ceiling below, sometimes in the unit underneath. Catching it early is the difference between a reseal and a major repair.
Limit the Damage
What To Do Right Now
If you think your shower is leaking, these steps limit the damage while you arrange a repair.
Stop using the shower if water is escaping the screen or coming through a wall or ceiling.
Dry the area and take photos of stains, cracks and damp spots.
Check the room or unit below for stains or drips.
Do not seal over cracks with sealer or silicone. It hides the cause.
If water is flowing when the shower is off, turn off the water to the bathroom and call a licensed plumber.
Find It. Explain It. Repair It.
Our Leak Repair Process
Every leak is different, so we start by finding the cause, not by guessing.
- 01
Inspect and Trace
We check grout lines, corners, the floor junction, the base, the drain edge and the fittings to see where water is getting out.
- 02
Confirm the Cause
We explain what we found in plain English. If it is a membrane or pipe problem, we say so before any work.
- 03
Repair the Cause
Failed grout and silicone are removed and the joints rebuilt with waterproof materials made for wet areas. Tiles stay in place where they are sound.
- 04
Cure and Recheck
The repair cures before the shower is used. We explain the cure time for your repair before work starts. Eligible repairs are backed by our 10 year waterproof warranty.
