Damage to airtightness seal around window

[Shell820810]

Our tiler has just ripped off the airtightness barrier around the bottom of window. I can do a bit of a patch up job where he hasn't tiled but what would you do about where it has been tiled?

Because of BREXIT, you are now allowed to hang, draw and quarter the Tiler. Think of all those wonderful old practices we can bring back. Can anyone think of something suitable for Plumbers?

Useful information to know  but doesn't solve my problem at the minute. Don't even talk to me about plumbers.

Flexible adhesive below the tiles ought to seal the wall/floor critical junction. If he hasn't grouted you could add sealant between the tiles and the external wall.

not grouted yet but tile is fixed with rapid fix adhesive and will have to be broken to be lifted but there is a gap I could fill with sealant. Good enough job compared to breaking the tile and retaping?

One has to question why, when we've had an air tightness requirement in building regs for many years now, a tiler decides it's OK to remove the sealing tape?

I mean, surely to goodness this won't have been the first time he's seen the stuff, it's been in common use for around a decade now.

A fix with flexible sealant is probably OK, but that's not really the point, is it?

[Shell820810]

Very frustrating Jeremy. I never even considered I would have to mention it. I told the painters to be careful when removing their own tape from the windows but why someone would just rip it off?

What depth would I need to leave for grout?

[Jeremy Harris]

I'd be inclined to forget about grouting the edge next to the window and just use a good sealant.  I'd also get the tiler to pay for it....................

I agree, grout always tends to crack when joining different materials, best use a flexible sealant. I was very impressed by the other thread with a u tube video on how good ct1 was ( and nicks comment on the white one going yellow).

I'm sure there's a good 5mm between tile and window, wont it be much more obvious with the sealer?

[Jeremy Harris]

Probably not if you opt to use a sealant that's a dark shade, like the window frame.  I doubt very much that a 5mm bead of dark sealant would really show at all, it it's done neatly.

Also dark sealer does not show dirt etc like white or light colours do

The grout against the door frame would come loose eventually as the frame expands and contracts with the sun so a good flexible sealant would be better.
