Our home is only six years old. We have a steel door with a large window,
that opens inward. We'd like to add a storm door with a large screen, so we
can leave the front door open during the summer.

How hard is it to install a storm door? Anything that would make the job
easier, or that I should avoid?

I'm not crazy about aluminum doors... Wood might look nice, but how will
they hold up?

Suggestions?
