Have a crawl space with what seems to be typical
vents: a plastic box w/integral screening that
is set into a notch at the top of the foundation
when it was poured.
The screen has been damaged and has a hole in
it. Hole is currently plugged with steel wool,
but would like to make a more permanent repair.
There doesn't appear to be a way to remove the
plastic insert and replace it; can anyone
suggest other techniques? Best idea I've had
is to make a wooden framework with screening
stapled to it and use tapcons to attach to the
inside of the foundation.
