Hi people having a problem finding a builder who will install a window I have . It is a first floor window at the moment it is a bay which should never have been put there I need to replace it with a flat window which I have aquired second hand its 3meters wide by 1 meter high. Any ideas where I could look I obviously accept that it is a risk I take if the hole is too small (which it isnt) I live in Bethnal Green
