Hello to all you people, I have just had some double glazing done on our house it was two 5 pane bay windows. when the fitter was putting them in I came back from work to notice there was a gap on both ends i.e. left and right of at least 40mm,he then filled it with foam well partly and then stuck a length of trim over it, I moaned that the gap had not been filled proper so he took it back off and this bloke gave me a load of bull s**t about it don’t need filling as it would be sealed on both sides, anyway he took it off and put some foam in it to make me happy he left the other end for the next day Wednesday . when some new bloke came with him to have a look who then left soon after, I think he came to check if the gap was expectable when they put the downstairs bay in it fitted ok I then asked why there was such a big gap in the upstairs one he gave me more bulls**t about what the frame could sit on so what I want to know what’s an exceptable gap it looks ok from inside and out has it is covered by trim should I get them back
