So my girlfriends sister is a drunk slut whos dropped out of college and now spends her time stealing stuff from my girlfriend (medication, clothes, almost $1000, the dog). I usually wasn't involved (cause shes fine when im there) until she beat up my GF to steal the dog while I was at work cause she knew I couldn't come help. Their parents are useless.
I'm putting in a deadbolt in soon cause she usually opens the door with a credit card (it has a lock) but shes kicked down the door before. Its a hollow particle board door and the soffit is unusually small (allowing for the credit card) and its old, thin wood.
Besides the deadbolt, what else can I do to reinforce the door, doorfame and hinges? And kinda on the cheap DIY side here. I aint made of money for a new door.
