Can wet insulation cause mold?

Wet insulation can be a health hazard that allows mold and mildew to grow. When you notice any damp insulation in your attic, you should find the source of the problem and fix it as soon as possible. Wet insulation is a serious problem. Mold begins to grow 24 to 48 hours after the insulation gets wet. One reason why it gets wet is a gutter that is no longer functioning well. The main function of your gutters is to keep the water away from damaging your home including your ceiling, walls, floorings, and even your insulation. You can have the cleaning done on your own but hiring a professional gutter cleaning service such as Gutter Cleaning Gainesville FL could help you save time and effort, 

Wet cellulose can be a health hazard, as it allows mold and mildew to grow within a few days. As a homeowner, you must be careful to prevent your cellulose insulation from getting wet. The insulation requirements of each roof are different, but there is one thing that is almost always certain: in the case of a recently discovered leak, wet insulation needs to be addressed. Closed-cell foam insulation is much denser than open-cell insulation and has a smaller, more compact structure.

Many choose cellulose loose filler insulation because of its insulating properties and because it is an environmentally friendly option. You should never force fiberglass insulation too hard in a small place, because compressing the fiberglass reduces the number of air pockets and makes it less effective as an insulator. The advantage of cotton insulation is that it is easy to clean and dry compared to cellulose insulation. Usually, wet cellulose insulation will develop mold within a few days or a couple of weeks, requiring a total replacement of the insulation.

The variables include the amount of moisture, the time the insulation has deteriorated due to humidity and the type of insulation available. Some of the insulation may be able to be recovered, but you would risk introducing mold or moisture into your new insulation. After all, water is a conductor, so wet fiberglass insulation is almost as effective as having no insulation at all. You know that your house has spray foam insulation if the cavities in the walls and floor are filled with hard white foam.

In addition, the density of fiberglass insulation makes it difficult for water to evaporate (usually this is only a problem when the insulation has been completely moistened, in which case its complete replacement may be recommended). Loose-fill insulation and fiberglass blocks provide your home with an effective cost-saving solution for air conditioning and high heating costs. So what should you do when you notice that your insulation is damp? Well, that will depend on the type of insulation you are dealing with.
