I've decided that the number one project on my list for my house in disrepair is the front door. While I'm not completely certain what's wrong with it, I believe that the door frame is actually loose so that the door can be pushed in even if locked. It was nailed shut at some point and hasn't been used since. I, however, in my recent 'take over' of this house, have decided that I like front doors and am going to have someone replace it. I read a bit about how to measure exterior doors thanks to another thread here, but didn't understand but about half of the terminology. So, again, that's something that I'm going to have to leave to the handyman.
My question, though, is what exactly do I need to consider when shopping for exterior doors. This is an older house, the current door is a flimsy faux wood if I remember correctly. Well, it's real wood but not actual wood panels more like mm thick strips of wood. I don't know. Anyway, I'm on a hugely limited budget. I'm a single woman that has grandiose dreams of one day actually crawling my way up to the poverty line. My employer apologizes every time he hands me my paycheck. Therefore, I cannot afford top of the line but I do want a quality door that I'll feel safe having. I also need a door that'll stand up to a fair amount of physical abuse. Not that I attack my doors on a regular basis but I'm farm-folk and don't do anything daintily.
What are some of the things that I need to keep in mind when shopping for this economical yet raging lunatic-proof door?
