Doorbell Installation questions, answered by experts

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation:

If the insulation is over 15 years old
If the insulation is wet or moldy
If it is vermiculite insulation
If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses.
