Removing Wet or Moldy Insulation
Your insulation needs to be removed if the following exists:
It is soaked and will not be able to dry
It is full of mold
Lifting the insulation up you find the area it is sitting on is molded and cannot be cleaned with the insulation in place
Removal of wet insulation is very time consuming.
If the insulation is blown - it will need to be sucked out with a commercial vacuum. This generally will be a very large vacuum with a 6 inch diameter hose. The vacuum will suck the insulation out of the attic and blow it into giant vacuum bags or directly into a disposal unit such as a dumpster. The insulation cannot be reused.
If the insulation is battens - it will be bagged up into commercial contractor bags while in the attic. The bags will be disposed in a dumpster.
