Replacing moldy insulation is crucial for maintaining a healthy living environment and ensuring your home's energy efficiency. Here's a comprehensive guide on when and how to address this issue:
When to Replace Moldy Insulation:
- Visible Mold Growth: If you notice mold on your insulation, it's a clear indication that replacement is necessary. Mold can compromise indoor air quality and pose health risks.
- Moisture Damage: Insulation that has been exposed to moisture or water damage becomes a breeding ground for mold and loses its effectiveness.
- Unpleasant Odors: Persistent musty smells can indicate mold presence in insulation, even if it's not immediately visible.
- Health Symptoms: Experiencing unexplained allergic reactions, respiratory issues, or worsening allergy symptoms indoors may signal mold-infested insulation. EnergySmart Insulation
