What to do when there is too much moisture behind shower tiles?

Hello,

If the inspector says that there is moister behind the wall then you will have to investigate and find out what's causing it.

A good place to start would be at the shower fixture.

Remove it and you will be able to see inside the wall, if possible get a camera in there and investigate. What you would be checking for is mold and then you could go from there if there is and take things apart if needed.

You will most likely need to replace the section of wallboard behind were the moisture was detected. If possible removing the tile from the wallboard first without damaging it or even better would be if you have extra tiles around or you can still buy the tile. In a lot of cases new tile will be required. Once you have taken some of the tile off you will be better able to tell from the conditions of the wallboard board how much more will need to be replaces. The cost will be determined only after you know the full extent of the water damage.

Hi There,

When in doubt replace it all especially if mould is concerned!

Remove all the drywall and tile and dispose. if there is grey or black on the back of the drywall its mould. Are any of the walls outside walls?

Is there insulation and vapour barrier?
