Mold insulation will look black in spots or streaks. In short, the old insulation has to be as dry as possible. Most of the time, we often think about our walls and attics when it comes to insulation. While most insulation can last 80 to years, insulation installed inside crawl spaces can only last about 10 to 40 years, roughly half the lifespan of other areas of your home.

The main culprit in affecting insulation in crawl spaces is moisture and mold caused by groundwater and ductwork. However, this is not always the case. Some homes located in southern states have no crawl space insulation. In recent years, contractors have started removing insulation from crawl spaces and opting for encapsulation systems. If you live in an area with high groundwater levels, your crawl space should have a vapor barrier — a thick layer of plastic covering the dirt floor in the crawl space.

This vapor barrier keeps moisture levels under control inside the crawl space. However, sometimes a vapor barrier, while necessary, may not be enough to control moisture. Ventilation is also essential. Crawl spaces require a good source of airflow to keep moisture levels low and the crawl space dry. However, sometimes a vapor barrier and ventilation are also not enough to control moisture. So now what? So what does all this have to do with insulation?

If the conditions inside your crawl space are dry, moisture and mold will form on your insulation. Wet insulation becomes stringy as the fibers start to separate. You need to replace wet insulation no matter how old it is. Replacing the insulation does little good if the source of the moisture problem is not addressed.

This may involve relocating air ducts from your crawl space to your attic. This opens up the crawl space for airflow and removes the source of condensation from the crawl space. If relocating your HVAC ductwork to the attic is not possible, you will likely need an encapsulation system with a commercial-grade dehumidifier to control crawl space conditions and keep the insulation dry.

How often should you replace crawl space insulation? Well, similarly, insulation in crawl spaces should last upward of 40 years when the conditions are right. However , crawl space insulation may need to be replaced in damp conditions as soon as 10 years after installation. In other words, you should replace your crawl space insulation as often as needed, primarily when the signs are pointing to the fact that it needs to be changed. The best way to know this is by having an expert inspect your crawl space insulation because it might be a bit more difficult for you to do so.

If they tell you that it needs to be changed with clear evidence, then you might need to change it. You can still expect most crawl space insulation to last 20 to 40 years as long as conditions are right. Similarly, attic insulation should last for the recommended 80 to years in ideal conditions.

However, attic insulation that is also exposed to conditions like animals and moisture will affect longevity. Attic insulation under normal conditions can last 40 to 80 years. How often should attic insulation be replaced? Attic insulation should last upward of 80 years when the conditions are right. Attic insulation may become damaged and need replacement as soon as 15 years after installation.
