Recently ordered a new double glazed window... thought i had the correct sizes and messed up, the window fits perfectly on the sides... but i somehow managed to screw up the height.. its 3cm's too short, Does anyone know if its possible to get a slightly oversized PVC window Cill at the bottom just to raise it up slightly... ive looked around and cant seem to find anything.. does anyone have other suggestions as to what i can do to fix this problem apart from buying another window :(
Cheers
