Why is my Prehung door not closing?

Re: Exterior pre-hung door won’t close

You will want to shim every 6 to 8 inches across the jamb to provide good support. From there, simply forcing a good bead of sealant, IMHO poly beutyl, along both the inside and outside. Gooping a bit of caulk around the shim packs will keep them in place just fine.
