As a result of a recent extension I've had fitted a set of Upvc

One of them appears to be fouling the lower frame of the doors

Looking at the three supporting hinges I am assuming that spacers
may be needed or is there normally some type of adjustment on
these doors.

Allen-headed grub screws in the hinges? That's what ours have...
