Old grout will be cleaned and filled with new grout to match the original grout where possible.
All internals will be resealed with high grade waterproof silicon. Colour to match your exsting tiles. "Sure Seal" will then be applied to all tiles and grout for a long term seal. This will not change the look of the tiles or grout.
A standard shower reaseal cost is $395.00. And is guaranted for 10 years.
