What Causes Mold Growth In Crawl Spaces?

If you have an older home, you may have noticed something furry-looking growing on the wood in your crawl space. This is most likely mold, and the reason it’s growing in your crawl space is because of three things.

Moisture: There is moisture in your crawl space, and if this moisture level reaches over 60%, you have the perfect breeding ground for mold.

Temperature: Mold has an ideal temperature for growing. But don’t start thinking that a colder temperature will stop mold growth: if mold can grow on food in your fridge, mold can grow in your crawl space in the middle of winter.

Food: Every living thing needs food, and mold is no different. Mold feeds off wood, and certain types of wood provide more nutrients for mold to grow.

Mold is a big problem for those suffering from asthma or other respiratory problems. Mold spores that are in the air can be inhaled by a person. This can trigger an asthma attack or other symptoms of an allergic reaction.

The best way to combat an allergic reaction to mold or to prevent an asthma attack caused by mold spores, is to eliminate the mold.

How To Eliminate Mold In A Crawl Space

Firstly, it’s important to check whether there is water present in your crawl space due to leakages or other plumbing issues. These issues need to be fixed immediately.

It’s also important to make sure you have proper drainage around your home, to stop any rainwater from entering your crawl space.

If your crawl space is damp, then the best way to eliminate the dampness is by using a dehumidifier.

In Conclusion

Your crawl space doesn’t have to be a breeding ground for problems- dehumidifiers help remove the moisture from the air to create an optimal humidity level. By choosing the best dehumidifier for crawl spaces, you will notice reduced incidence of mold and the associated respiratory problems. And a stronger and safer foundation for your home!
