I am replacing the old bathroom ceiling fan and had to remove the whole housing unit.
I was able to get the old one out but now I realized the vapour barrier is not intact. Me yanking out the fan didn’t help, but to me it seemed this wasn’t properly installed to begin with.
I also noticed the insulation to be moldy.
- can I live with this or is it advisable to remove the drywall ceiling and re-do this?
- if I only line the hole for the new fan with 6mil sheathing how do I manage to efficiently plug the hole for the duct and electrical?
Thanks for any advise,
