High-Performance Tile & Stone Regrouting
Restore worn, cracked, or discoloured grout and get tiles that look new, without the cost of replacing them.
Stop Water Getting Past the Grout
You scrub the shower, bleach the grout, maybe squeeze some sealant from a tube you bought at the hardware store. A few months later, it’s black again, or the tile by the drain has started to move.
That’s water getting under the tiles. Once it reaches the waterproofing and the timber below, a simple leak turns into a full bathroom rebuild.
When grout cracks or crumbles, water goes straight through it into the bed under the tiles.
Over time, that means mould, loose tiles, swollen timber, and floors that turn slippery.
Regrouting blocks that path.
We remove the damaged grout, pack in new grout properly, and keep the water on the surface where it belongs.
Regrouting vs Replacing
At The Stone Restoration, we regrout showers, floors and balconies across Melbourne. Including marble, granite, limestone, bluestone and terrazzo. We remove the failed grout and refill the joints, so you keep the tiles you already have.
When we regrout, you get:
- Grout lines that stay sealed, so water sits on top of the tile
- Grout that stays cleaner for longer, instead of going black again
- A result that costs far less than retiling the room
The Right Grout for How You Use the Area
Different areas leak differently, but the goal is always to keep water on top of the tiles, not underneath.
Epoxy Grout
For showers and balconies. It handles water and stains well.
Cement Grout
For dry floors, it’s easier to match to older grout.
Flexible Sealant
For corners and movement joints, so the grout doesn’t crack where walls and floors move differently.
Leak Check First
If we find a failed membrane or damaged subfloor, we tell you at the leak check. You don’t pay us for grout that can’t solve the problem.
Colour Samples First
Before we start, we hold samples next to your tiles so you can see how it will look.
From Leak Check to Sealed Joints
We check whether the leak is coming through the grout or from a failed membrane or subfloor.

Removing Old Grout
We cut out the loose and cracked grout to at least 3mm deep so the new grout has a solid channel to grip.
Steam Clean
We steam clean the open joints to pull out and remove oils, dirt, and mould.
Epoxy
We pack in new grout.
Seal
We seal the edges and movement joints with flexible sealant.
Cure
The exact curing time depends on the grout we use; we tell you the safe time frame before we leave.
Regrouting only works if the waterproofing under your tiles is still intact. It can’t repair one that has torn or rotted.
Regrouting Marble and Limestone Without Damaging the Edges
General tradies and DIY attempts often use angle grinders on grout lines.
On soft stone, that chips the edges and leaves scratches you only notice when the light hits across the floor.
We use slow, low-speed grout removal tools with diamond blades. So the grout comes out, and the stone edge stays crisp.
Leaking Showers and Balconies Fixed at the Joint
Showers and bathroom floors
Epoxy in the joints, flexible silicone in the corners.
Balconies
Rain finds every crack, then leaves white powder on the surface as it dries. We replace the failed grout with UV-resistant epoxy and flexible joints that cope with sun and movement.
Stone floors
We can regrout and, in the same visit, grind, polish, and seal the stone so the grout and the stone finish together.
Not Sure If It's the Grout or the Membrane?
Take a few clear photos of the worst areas, and any nearby swelling, staining, or soft spots. Send them through, and we’ll tell you if regrouting will fix it or if you’re looking at a membrane issue instead.
If you want a price, we’ll book a free on-site quote with a moisture check anywhere in Greater Melbourne.
