Ooops crack in window

Well the workmen arrived nice and early to install the new door and porch windows..it was looking really nice too. But I just heard this almighty crack and one of the workmen holding his head in his hands. On inspection I have a bloody great crack down the new porch window..eeeks. So I think they are now ringing to get a new one pretty damn quick, as I am not going to give them the cheque upon completion now.. :-(

Its one of those things so cant be helped, thankfully they arent that far away so should be able to bring a replacement quick. Although it has to be cut to size and the bevel done too.. Hope its done before Dave gets home tonight otherwise he wont be very impressed..eeks.
