Can you use expanding foam instead of Mortar ???

Thankyou Woody

The builder said this morning that the sills would be dry packed with mortar - they had to fit the sills quickly when the window fitters turned up.

Does this sound reasonable?

You don't have to have plastic sills with plastic windows (they do look poor with those nice sandstone sills) but that's part of the initial measuring and sizing process so your options now are limited.

Yes it does.

The whole estate has been done like that - so these have been done the same to match!

Thankyou everyone for taking the time to reply. We will wait and see what they do now

The outer brick work is say 100mm deep, the window frame often 70mm deep. If the window is installed flush with the outside brickwork then this leaves 30mm of brick inside of the window frame.

If your internal plasterboard is attached to this; guess what happens when that brickwork at -3C meets your inside temp?

I might be wrong, but it doesn't look as though the window frame is flush with the outer skin?

 

[Pieinthesky]

The window frames are about 50mm in from the face of the bricks which I believe is OK

 

[Swwils]

Yes and left about 20mm overlap over the cavity

They are not supposed to be!

I know that.
(A previous poster had commented that the window frame appeared flush with the brickwork face).

Thank you for confirming.

A quick update on this one.

The builders today pointed the out side joints on these sills.

I don't know how deep they went and they have not done the inside.

I am tempted to run a drill through to see how deep they have gone!
