The side door on my house needs to be replaced... The door, jamb, everything. It's a wierd size....it's 30" wide by 77" tall. The ugliest, most boring custom prehung door for that size starts at $475 at Menards.....anyone got any other suggestions? The door is under a staircase, so it has to stay the same height. I might be able to go a smidge wider.....and of course I'd like it to be an economical fix!
