The foundation (crawlspace) access door to my house is rusty and
falling apart. My house is a 1967 brick-sided ranch house. The door
opening is 32"x16" and unfortunately no local hardware stores carry
this size. I would like to replace this door but it doesn't seem as
simple as just replacing the door and its frame. I think it's mortared
into the foundation but am not entirely sure. Are there replacement
access doors similar to replacement windows that attach to the current
frame or must I get a brick mason to replace this for me?
