I’ve recently had my windows replaced by a local company, some of the windows have smear marks on the inside of the glass ( in the inside of the gap) which is noticeable in the day. The company said it’s where the glass production staff haven’t cleaned the glass properly and they would sort it.
Anyway I’ve noticed that if you shine a light on the windows ( and I mean a bright light like a halogen floodlight) from the inside at night you can notice similar smears that are NOT noticeable in the day.
Should I make an issue of this or will it cause me issues in the future?
Granted the majority of the time you would have the curtains drawn and have have normal lights on and I only noticed it because I was painting and had halogens on.
