When grout expires it becomes porous and returns to its original state – a powder. You might notice spots of mould that cannot be scrubbed clean as it is inside the grout rather than on the surface, or you may notice cracking in certain areas of your grout lines. Any hole or crack in your shower area allows water to seep through underneath the tiles. When silicone starts to lift, peel or have pockets of air underneath you may notice mould and discolouration that is impossible to get clean. If mould can get in, so too can water and this is a very good sign that your sealant needs replacing. Checking your grout and silicone areas to ensure it is still effective and resealing if required not only does its part to ensure wet areas are protected from water penetration, it also looks fresh and rejuvenated. We use high quality grout and silicones with Anti fungal properties to ensure our products longevity and match the colours to suit your tiles.​
