Bathroom grout deteriorates over time — cracking, staining, growing mould and eventually failing to seal the joints between tiles. Professional grout repair and replacement restores the bathroom’s appearance and, more importantly, its waterproofing.
Types of Grout Damage
Cracked grout — from substrate movement or thermal cycling. Allows water to penetrate behind tiles.
Stained and discoloured grout — from mould, limescale and general use. Cannot be cleaned back to white in many cases.
Missing grout — where grout has fallen out entirely, leaving open joints.
Failed mastic at bath/shower joints — the silicone sealant where tiles meet the bath or shower tray is a separate issue from grout but equally important.
Grout Repair Options
Localised grout repair — where only a small area of grout has failed. The damaged grout is raked out and replaced with matched grout.
Full regrouting — where grout is generally in poor condition across the bathroom. All existing grout is removed and replaced.
Mastic replacement — the silicone sealant at bath/shower/floor junctions removed and replaced with fresh white or coloured silicone.
Cost
Localised grout repair: £75–£150. Full bathroom regrouting: £200–£500 depending on size. Mastic replacement: £75–£150. Send photos for a fixed price.
