Hi!
I just moved into an apartment which I later found out that there is air coming in the apartment which makes the humidity levels go down to 32-37% and drops the temperature.
While investigating the windows I found out that the sealant is cut in multiple windows at the top part which is bringing in the cold air.
Here is the photo of the window: [https://imgur.com/a/lThlupv](https://imgur.com/a/lThlupv)
​
How can I fix this?
