Most "leaky showers" aren't a tiling problem. They're a grout and seal problem.
Grout dries out and cracks
Over time grout shrinks, hairline-cracks and lets water through to the wall and floor behind the tiles.
Mould, stains, soft floors
Black mould in the corners, discoloured grout lines, and floors that feel soft near the shower are all downstream of that.
Regrout, reseal, done properly
We remove the failed grout and sealant back to a clean joint, then rebuild it so it's actually water-tight again.
Regrouting now is cheap. Fixing it after it spreads isn't.
Stops water reaching the frame
Failed grout lets water track into the wall and floor structure behind the tiles — caught early, that's a regrout. Left alone, it can mean rotten timber framing or a corroded steel frame.
Avoids a full retile
A regrout and reseal costs a fraction of ripping up and relaying tiles once water damage has gone deep enough to need a full waterproofing redo.
Keeps mould and mildew out
Gaps in grout and silicone trap moisture — the longer it sits, the more mould builds up in the wall cavity, not just on the surface you can see.
Protects downstairs neighbours & floors below
In apartments and multi-storey homes, a slow shower leak can travel down into the ceiling or unit below long before you notice a problem upstairs.
Protects your property value
Visible water damage or a history of leaks is a red flag at building inspections — sorting the grout early keeps it off the report.
Quick job now vs. major works later
A regrout is usually a same-day job. Structural water damage means demolition, drying out, waterproofing, and re-tiling — weeks, not hours.
Six jobs. Done right.
Grouting & Regrouting
Cracked, crumbling or missing grout dug out and replaced properly, so the joint holds and the water stays out.
Epoxy Grouting
A stronger, stain- and water-resistant epoxy grout upgrade — built for wet areas that take a beating.
Caulking & Silicone Sealing
Old, mouldy or cracked silicone cut out and replaced along edges and corners, so movement joints stay flexible and watertight.
Tile & Grout Cleaning
Years of soap scum, mould and grime lifted out of the joints — grout looking new again without replacing a single tile.
Waterproofing & Sealing
A sealed, water-tight barrier behind the tiles — the actual fix for a shower that's been leaking into the wall or floor below.
Grout & Silicone Resealing
Routine resealing to keep grout and silicone doing their job year after year, before small gaps turn into bigger leaks.
Before & after.
