A bad case of degraded grout and silicone
The shower was leaking through to the ground floor. A number of tiles were cracked with a large number loose.
We removed all the damged and loose tiles.
We then machined out the grout in the whole shower enclosure.
We made good the wall an replaced all the tiles before regrouting, for extra protection we used a trim around the base. Finally we carried out a professional tile clean and polish.
I think you will agree that the results are dramatic.
