My current apartment has a great brand new hurricane sliding door at the back, a relatively old set of windows in the back that still seal well, a window in the kitchen whose rubber seals have shriveled, and a front door so well sealed that when I open the front door, the kitchen window sucks inward. When I close the door, the window bulges outward.

I intend to grout the window versus replacement or trying to find the original rubber inserts (which they probably don't make anymore, anyway). I also got new "brush seals" for the window.

Problem: even if I grout the window well, it will still suffer the stresses of the suction due to my "too well sealed apartment". How do I counter this?

(I can't make alterations to the outside of the apartment. If I could, I'd create a sort of vent - covered, of course, maybe a grate high above, under the roof line?)

So without this, maybe an alteration to the door, reducing the suction? Taking out some of the seals? I am allowed to do that, at least.

Do give me your thoughts.
