How to Get Rid of Black Mold on Insulation blog header image
August 18, 2022

Your home’s insulation isn’t very easy to inspect, as it’s usually hidden behind drywall or in cramped, hard-to-access parts of your home, like your attic or basement. But if you do ever come into contact with your insulation, you may notice black stains on the insulation material. Does this mean that your insulation has been compromised? Is your insulation still able to help protect your home? 

The Dangers of Mold on Insulation & How Insulation Can Make You Sick

Most often, mold is found on insulation due to moisture issues in your home—either high humidity or actual water leaking or draining in your home. Mold on your attic insulation can also be the result of condensation—warm indoor air rising into your attic where it meets cold air in the winter.

You may have heard that black mold is toxic, but that’s only a specific type of black mold, and it’s much more likely than not that any moldy insulation you find in your home is not the toxic kind. That doesn’t mean, however, that it’s okay to just leave mold on your insulation as is and ignore it. The risks of indoor mold growth on insulation—even the non-toxic types—include:

  1. Allergy symptoms (Coughing, congestion, itchy skin, watery eyes, sneezing)

  2. Structural damage to your home (mold can spread from insulation and lead to wood rot)

  3. Unpleasant musty smells throughout your home

  4. Damaged insulation (a number of insulation types are essentially ruined if they get wet)

Black Mold Solutions: Moisture-Proofing & Insulation Removal

There are a few steps you should follow when addressing mold on your insulation:

Removing any moldy or damaged insulation

Mold-covered insulation should be removed and disposed of by a professional—DIY insulation removal can make poor indoor air quality even worse.

Addressing the underlying moisture problem that led to mold

You don’t want to pay to remove and replace your old insulation only to find mold growing on the new insulation soon after. Moisture issues can be solved by identifying the source of the problem, which can include air leaks, roof, siding, or foundation leaks, and more. One of the most effective ways to prevent moisture or water from returning to damage your insulation is air sealing.
