Will someone tell me why you can’t just put in a door you buy from the store?
It’s weird, but every door frame is slightly different. When you buy a new door (which will run you a few hundred dollars for a solid wood external door), you have to have it shaved to the exact shape and possibly have holes drilled in it for the hinges, since every set of hinges is placed slightly differently.
Seems like a good argument for metal frames. I would buy a metal door, but knocking on a metal door makes me feel like I’m living in a freezer. And incidentally someone who installs doors is referred to as a “hanger.”
