/diy/ - Do It Yourself

what do i do if i have 400 year old windows killing me?

the wind blows in the perfect direction of my window and it smells really fucking musty and moldy. we have non stop hurricane winds here and now my entire house smells moldy right from that window and the closer i get to my room the worst it smells. i cant even be in my room anymore i sleep in a fucking storage with junk and shit everywhere sleeping on the floor and still smell it.

plus my moms retard cat pissed all over it so now it just smells like crisp windy air, mold, and cat piss every single second. my parents are too stupid and poor to replace or live in a proper house

I HATE MY FUCKING LIFE

do i just weatherproof this window by sealing it up? or will that not do much?
