It’s a Bellway home but they only give you a 2 year warranty, would I be best going to NHBC

I’ve not had the heating on much in the past year as the house is warm enough, but I did find all the trickle vents in the upstairs windows were closed, would this cause it ??

Thanks for the replies, there is plenty of insulation in the loft and it’s happening in a few areas not just at the extract fan, I’ve found 2 rooms showing the mould and found moisture between the sheet and plasterboard at 3 other areas, how can I prevent this from happening and can I cut away the visqueen and just leave the insulation in place

Hi, im looking for some advice, I recently noticed mould spots appearing in a few rooms of my 5 year old new build house, when I investigated in the loft I found no leaks from the roof but did find a green plastic sheet that looks as if it comes up from all the external walls and then folds under the ceiling joists between the plasterboard and joist, it was between this sheet and plasterboard that I found moisture, what would be causing this and should the plastic sheet be there in the first place, I have attached a few photos that show better than I am describing. thanks in advance
