Bathroom tile problems come in two main forms: damaged grout and damaged tiles. These are different problems requiring different solutions — and choosing the right one saves time and money. Here’s how to distinguish between the two and what the appropriate fix is.
Grout Problems vs Tile Problems
Grout Issues
Grout discolouration, cracking, crumbling, mould growth and joint failure are all grout problems. The tiles themselves may be undamaged. Grout problems are addressed by re-grouting — removing the old grout and applying fresh grout to the joints. This is a separate task to tile repair and is not what surface repair specialists typically do (it’s more closely related to tiling work).
Tile Problems
Chips in the tile face, cracks running through the tile body, corner breaks and surface scratching are tile damage. These affect the tile itself rather than the grout joint. This is the domain of surface repair — where a specialist fills, levels and polishes the damaged tile to restore its surface.
Can Both Be Done at the Same Time?
Yes, but they need to be done in the right order. Tile chip repair should be carried out before any re-grouting work — because chip repair compounds need clean, undisturbed edges, and fresh grout in the surrounding joints provides a cleaner reference for the repair. Attempting re-grouting first and then a tile chip repair can contaminate the repair with grout residue.
When Tile Replacement Is Needed
A tile with a crack running entirely through it is structurally compromised. Repair may improve appearance but the crack will eventually widen as the tile flex. For through-cracks, replacement (if a matching tile is available) is the more durable solution. We’ll advise honestly if repair isn’t the most appropriate solution for your specific damage.
