Tiles Loose

[Onoff]

Got some tiles loose/ falling off I'm going to try and fix:

 

 

This is on a later, bathroom extension on an 1860s terrace.

 

From the outside. That's the bathroom window above the garden box:

 

 

Then the return wall:

 

 

 

I was thinking the reason the tiles are falling off is a) because the decking is too high and b) maybe as the garden box is up against the wall. Expecting then to see major damp on the inside I removed the bath panel. Doesn't feel damp:

 

 

 

Doesn't look damp:

 

 

 

Maybe just poor tiling to start with?

I thought damp, black walletc...... looking at the grout, and at that wall to the left of the bathroom window. I still think it could be, but could also be water going down through the tiled window cill when the shower is in use. Rip off a tile and let us know.

I'm thinking that the bathroom extension was done after the original house was built, then this particular suite fitted later. I'll have to have a look at neighbouring properties though since the 1860s there's probably been more than a few changes!

 

Looking to replace the decking probably with some sort of pebbles in a pseudo French drain detail against those two outside walls. Maybe 150-300mm wide.

 

Half a plan to remove those loose tiles and if the wall is OK, tank it then re tile.

It might be as simple as the wall was painted before and they've tiled straight onto that. If that's the case I'll have to heavily key it I guess or sand the paint down/off.

I'm not sure if the blue circled / dotted joint is the dpc:

If you do that the gully should be able to take away any water. Whatever the wall has been coated with won't help. I'm interested now, so keep me posted. I would guess that is where the old slate damp course is, but on those old buildings you always have to dig around to find it.

Interesting detail I noticed today above the lintel atop the window:

Pretty sure water was getting down through the tile trim on the window sill, it was loose.

 

 

 

I prised it apart and filled with BT1 then Fugi'd / baby wiped off.
