Mold not only causes allergy, but it also brings about degradation of your insulation material. After lying in neglect for years, the attic insulation material becomes infested with mold, rot & algae. Mostly, it is the mineral wool, roll mats, spray-foam and loose-fill cellulose material that aggravates the process of fungus, moss and mold growth due to the moisture levels in the air and also due to condensation in the attic.

If you have confirmed that your attic insulation has mold, here is how you should remove it by taking our expert help.

How to remove mold from porous insulation

You should start by opening your household windows and doors in order to ventilate the area. To circulate air and dry moist surfaces it’s wise that you use fans. If the mold is visible as black or green stains you should avoid using a fan.

You should protect yourself from mold by wearing a respiratory mask and latex gloves. You should then brush all the contaminated insulation with a wire brush. If there is wet insulation you should remove it and allow it to dry. If your insulation is loose fill you should dispose of it as it’s impossible to clean.

After removing the mold you should scrub the contaminated surface using a wire scrub brush, detergent, and bleach solution. For ideal results you should allow the solution to sit on the surface for at least 10 minutes. This is for thoroughly disinfection to take place.

Once the surface has dried you should spray fungicide on it in order to protect it against mold growth. After drying you should re-install the insulation.

How to remove mold from non-porous insulation

Here you need to remove the insulation entirely from the contaminated area and then scrape the non-porous insulation (such as fiberglass or rigid plastic) using a metal scraper. You should then scrub the contaminated surface using a wire scrub brush, bleach solution, and detergent.

You should then douse the insulation in a bleach solution and scrape it clean with a wire brush. You should allow the surface and the insulation to dry thoroughly and then re-install the insulation.
