Today's "New Window" fitting has been a mixed-bag.
The manufacturer made a mistake and supplied the wrong size of corner posts, and not enough sealing strips for the glazing.
The window-fitters have gone "off-piste" and fitted a hideously large Ali windowsill to my small casement window which has a tiled sill.
I only discovered this after they had left for the day, called their office and said they would need to remove the hideous monstrosity, office agreed its the wrong sill/trim for a casement with tiled sloped window-sill's.
They will be back tomorrow to "finish" fitting what they have, and then revisit in 10 days when the correct sized corner-posts appear.
Despite these disappointing elements the overall effect of the new windows is pleasant and quite dramatic.
