gazmondo35, depends who you get as anywhere.
Had mine replaced twice by autoglass within the last 9 months and they have done a smashing job both times. On the first one there was a little too much glue on one part of the windscreen that pushed in so was visible a little bit, but didn't want to have it disturbed so seal stays intact.
Not that I have much choice (leasing companies supplier) but would have it replaced at home by them again.
