Nancy, Feasible? That's relative, no? If you need to ask "how" to remove the door, is it feasible to assume you can put one in? TomR gave a good exposť on the remove but, if your door has a nailing fin, it is probably concealed by the outside finish i.e. brick, stucco, vinyl or what ever. Removing this type of door requires a little more knowledge. And what about the installation of the new door? Is it "feasible" to assume you can do this job as well. I still would go with my first post.
