Hi there, just looking for some advice. This tile job/grouting was done by a professional tiler in our ensuite and shower cubicle..we feel it's not done particularly well, adhesive is showing through in some parts and there are gaps and pinholes which presumably will let through moisture? Will redoing the grout fix this? There are also some chips where tiles have been cut, if the grout is redone will these be less visible or are they not salvageable? Any help appreciated! Thanks!
