We've just had our double glazing replaced. The photos below are one example of how badly the windows have been finished. They look worse than the old ones 
AIBU in asking him to come back and improve the finish? He's already not happy with me because he didn't take a rollerblind down and installed the window and beading around it, which meant there would be a chunk of beading missing when we replaced the visibly-old and crappy blind. He's also massively damaged the paintwork around the windows - much more than I expected.
It's also really awkward because he's a friend of DH's . . . ugh. That was probably our first mistake . . .
Is this normal? I honestly expected them to look nice and clean and new
