Hole at bottom corner of outside window? what is it?

The window shouldn’t fall out if you push on it, but given the botch job that has been done when the plastic windows were put in who knows.  Bloomin’ cowboys

My brother had something like that whole, but even bigger, and the only thing which helped him - was to ruin that area, for renovation, and replacing a window as well.

Eventually. Words of wisdom. But to technical for me sorry.

Poorly installed replacement PVC window. No, patchig it willnot make the window fall out (unless perhaps if you happen to use the same cowboys who installed the window).

But leaving it unpatched could allow penetrating damp. Any signs inside of damp? Mould?
