Yup, it is what it is.
Problem with the setup is, every door is an unusual size, so nothing off the shelf can replace them without redoing all the jambs...........and the issue with that is, if I do anything with resizing, I could never match the Stain/paint/molding ect ect... that's there now
for door sealing, they use standard 8' sections and cut to match door dimensions. It seals from the outside and comes in white and dark brown. Its just metal/rubber so you can paint it. I have not seen the same item in big box stores, but I'm sure you can order it somewhere.
