Good in the right places...

Our half round gutters obviously do not fit the square T at the top of
the fall pipe, so the installers instead of obtaining an adaptor, just
stuck it in with expanding foam.

And this is not one of them!

The question is, is this adeqaute, or can we expect deterioration and
problems later? I suspect the later.

Nope it is a total bodge (the foam breaks down with UV exposure and is
not totally waterproof to start with). Get the neighbour to have em back
to do it with the correct connector!
