It is a real concern about water ingress leading to mould; any responsible Council would be on top of this.I know very well how frustrating it is trying to contact the relevant people in the Council, let alone trying to get them to actually do anything!However, for what it's worth, you should try and contact Western Area Housing Team: 020 8871 5530 / hms@wandsworth.gov.ukKeep pestering them and copy emails across to councillors etc. This needs to be sorted without delay, before winter does its damage.We paid top dollar for the windows, which are proving to be very second rate!
