I want to replace an old wood entry door (garage to house). It is pretty beat up and split, plus it doesn't match the rest of the house (panel). What is the easiest way to do this? Do I have to rip out the whole frame, down to the rough opening? Are there any code issues with these types of doors (i.e. swing)? I might want to change the door swing, if it doesn't create a lot more work for me.
Bottom line, how hard is this (for a DIY with little carpentry experience)?
