Replacement bathroom fan

Post by Nilzor » Sat Mar 16, 2019 2:09 pm


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,
