Tiles falling off

[Qwerty]

Yep, sounds like tubbed addy is the issue

I'm not so sure!?! The lead flashing may have failed on the chimney stack, and water is running down the wall. Or it could be condensation, as he's said...
If its a wet area, then I'd agree, as he shouldn't have used tubbed gear in a wet area anyway.

I am sure the property owner would notice if the lead flashing has failed and water was running down the wall - but we are asked to give advice with only bits of information and a lot of guessing so it's possible that there isn't even a roof on the building!
At the end of the day the chimney may be a red herring and it's water ingres through the joints where the grout has cracked, he may have tiled onto emulsion and this is the result of the drying out or ............

Ooooookay.. The affected area is the chimney breast. No mention of this being in a wet area. If the tiler thinks it must be condensation, i would assume, it's because it's not in a wet area, yet the adhesive is getting wet. I'd say the tiler is trying to make an educated guess. It's very easy to say its the tilers fault, but at the moment, I don't see anything that suggests this. Like you say, not enough information here to start making accusations. 😉

Hi all
The tiler that did the work (before I got involved) insists that the problem has been caused by condensation but I don't buy that as surely the wall should withstand water etc from a shower.


The Op stated a shower area.
Would suggest tiler is making an educated excuse!

Chimney breast? My money is on GRR synopsis

 

[White Room]

During the heavy rain quite a few people were having problems with moisture getting through the brickwork causing some damp problem from internal chimney stacks.

 

[Dougs Third Go]

is the chimney stack vented, top and bottom?

Im with whitebeam, rain has been that heavy these last few months it will of got up a fishes backside.
Id put money of slates/flashing, water running behind tiles .

Hi all
Firstly thanks for all your replies & opinions
The chimney breast is the opposite side of the bathroom to the shower. Thee point I was trying to make is that on a shower the water is directly on to a tile with little or no detrimental effect so had could condensation on the surface of the tile cause to to fall of f the wall
The residue from the tile was like tubbed adhesive mixed with water & tiled directly onto cinder concrete blocks (so will use a rapid set when refixing tiles)
When I revisited & got onto loft above the bathroom you can see daylight from behind the stack Also two large cracks in the external render & a missing tile So I think we can resolve the issue
Thanks again for all you advice

So I was right - it wasn't the tilers fault!
