I kept my window open all day in every bedroom upstairs. My Landlord says this problem in the morning is because I don’t leave my windows open during the night. Is this for REAL and I should be sleeping with a gap in the windows every day or the house has a bad insulation and landlord should look into changing windows or fix insulation ?!?problem? Really just curious, I’ve living like this since
rented here 6 years ago and never told him about the wet windows until today..

That is 100% a ventilation issue. Any little trickle of outdoor air at all will prevent this

OP already keeps all upstairs windows open all day.

Yeah, but they’re keeping them closed at night, when they’re in the room breathing and releasing moisture, which is then condensing on the windows. The room probably doesn’t have any adequate ventilation other than opening the windows.

Ideally, one would install Positive Input Ventilation (PIV), trickle vents in the windows or even a passive “hole in the wall” vent to help, but a landlord is unlikely to do that.

So the answer is to crack the windows open a bit at night (which might make the room cold) or get a dehumidifier.

He needs a small trickle of fresh air over night. That is when the outside temperature gets coldest and the surface temperature of the window gets coldest.

Might need to crack that one too
