Replacement bathroom fan

Hi,

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 didnít help, but to me it seemed this wasnít properly installed to begin with.
I also noticed the insulation might be a bit moldy - maybe itís just dust from the fan. This has been broken for a long time and the duct was not attached properly

- 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?

Welcome to the forums.

If there is an attic above that fan then it needs to be insulated. The flex duct exhausting the air needs to be insulated too.

The attic is not directly above it. Itís less than a 10 inch clearance and itís stuffed with insulation

If it's not a cold zone above then it doesn't need to be insulated.
