Hello,
Just found out that there are water slowly leaching out of the grout between the tiles outside of the shower (just next to the shower)
The bathroom is upstairs, there is no sign of leaking/water damamge downstairs as yet.
What could it be the problem? and who should I call to inspect?
would a plumber do? but if it involves tile job shall I also call a tiler?
Just want to get it fixed...
Thanks heaps
