Crack in inside? Window?

[TheOpalFox]

See that white line on the left? It’s a very slight crack in my window??? How can it h.appen? Shall
I tell the council ? Weird how it’s happened? No one has touched it? And it’s on the inside

Pressure change

What’s that please

Can’t see a photo!

Here it is

I do attach a photo then it don’t show :(

It’s not there!

@TheOpalFox no photos showing yet. They might be waiting approval....

Will try and add it again

It could be thermal shock. We had it happen to one of the windows in our bay window. The house was really warm but the weather outside was baltic.

I think you can see it now?

Showing now ?

If it hasn’t been subjected to trauma, perhaps it’s a stress fracture. In any case the council should replace it as the crack will likely spread
