Does Existing Attic Insulation Need To Be Replaced Before Adding New Insulation?
One of the first questions that come to mind when people decide to upgrade their attic insulation is “do I need to replace the current insulation?” Odds are, most likely not.
You do not need insulation removal service unless the following applies:
- There is fire or / water damage (insulation needs to be removed to prevent mold growth)
- There is untreatable mold on your attic insulation
- You have a substantial animal infestation from chipmunks, mice, squirrels, chipmunks, or raccoons.
In these situations, it is recommended to vacuum, offsite disposal and disinfection. If that’s the case there are funds available to you if you have asbestos from a zonolite plant. (https://www.zonoliteatticinsulation.com)
A professional will also disinfect the attic space before and after the insulation is removed to reduce contaminants in the rest of the home. Home insurance may cover the cost of removing and reinstalling your attic insulation for the situations listed above if it is included in your home policy.
If you have a mold infestation, it is possible for your existing attic insulation to remain in the house as long as there are no signs of mold growth on the insulation and the insulation is treated at the same time as the rest of the attic to kill all the mold spores and prevent it from regrowing.
