wet insulation
 
I found wet insulation in a bedroom. I pulled the paneling off and there it was. Since i fixed my roof do I need to replace ext.wall as well?

Pull out the wet insulation.
Check all areas near that location.
Check the attic as well.

Inspect the back of the exterior wall for rot, mold, damage. If located, treat accordingly.

If it just looks wet, dry it out. If it is really wet: rent a blower.

Once it appears dry - use a moisture meter to check it and the connected areas.

If you have any suspicion that there is mold there, again = treat it.

Once all the interior of the wall and exterior is allset, install new insulation, close up the area.

The ext. wall is now dry, we don't have an attic, so I would have to take some siding off?

Unless you are seing signs of mold, the siding should be fine. Have you tested the areas for moisture?

Don't bother to try to dry out fiberglass - just toss it.

It only takes 1/2 to 1% moisture to cut the insulating value in half. I doubt you can afford a moisture meter that is that accurate for something like fiberglass.

If there are any mold spores, you will just be putting them back along with the old insulation. Treatments don't do much to the spores (seeds) but they will kill the active mold.

As Atlantic says, treat any area that you think may have mold. It is cheaper than trying to find out if there is mold, since you cannot really see all of it.

I haven't tested it. Where does the musty smell come from? I threw out the paneling and insulation and after I clean the wood with bleach water I should be ok to put the insulation back up? Along with drywall?

After you spray the bleach solution, let it dry thoroughly before you put the insulation back in and close things up.

Don't waste your time putting up insulation that was wet. It is just too cheap to use new compared to any problems.

Letting fiberglass dry does not work because it is designed to trap air and stop circulation if it is faced.

Do not use bleach, it is innaffective on pourous surfaces. It will not kill mold spores on wood. Bleach only works on non-porous surfaces (like countertops).

A home remedy for killing mold (on porous surfaces) involves using a strong mixture of white vinegar. Do your research on the whole subject...

I was reading up on the subject again and I can't find where I should use vinegar. Can you tell me what site to go to? I would like to do this the right way. I did see that I should not use bleach though.
