What Causes Green Mold On Walls

What is Green Mold

Mold growth on clothes and furniture is due to excessively high humidity. In a warm/humid climate such as the Southwest US, this occurs when the air conditioning is not adequately stripping the humidity from the air. In wet/cool climates such as the Pacific NW, this occurs in poorly heated rooms or closets with inadequate ventilation. The answer depends on your climate. If this is occurring during the winter months and you live in a cool climate, increase your heat and ventilation. The easiest way to improve ventilation is by simply running your closest bathroom exhaust fan 24×7.

If you live in a warm/humid climate, contact a HVAC company to investigate the issue.

In both scenarios, your goal is to keep the relative humidity below 60%, ideally below 55%. You can purchase an inexpensive RH gauge for ~$30 from a hardware store or online.

Don’t Finish Your Basement Unless It’s Very Dry

Don’t finish the walls of your basement with insulation and wallboard unless your basement is very dry. Also avoid putting wall-to-wall carpet on your basement floor.

Specialty coatings designed to stop vapor movement do exist, but they typically work best on new concrete.

How Is Mold Caused

Green Mold – How Dangerous & Toxic Is It?

Mold is mostly caused when something that can support mold is exposed to water. Since mold is highly adaptable it can grow just about anywhere. Plywood, drywall, carpets of all kinds all provide food for molds. Having any of these thing improperly dried during construction or after a major storm can allow for mold to take hold and then behind to spread. The three things molds use to grow themselves are a food source, generally this would be cellulose, then some water, and then finally time. Sections of your house that have been exposed to water damage that are left unmonitored are prime breeding grounds for mold. Mold could be inside your walls, hiding behind wall paper, in the pipes of your sink and toilet. Theres plenty of places where mold could be hiding and you could be completely unaware its there.

If you live in a climate with cool winters, this can be achieved by increasing the ventilation to the storage area and increasing the heat/temperature. The higher the temp, the lower the RH. Purchase a relative humidity gauge to monitor your efforts. If you live in a very humid location such as Florida, youll need active dehumidification.

Humidity problems are typically worse in closets or cabinets, due to the poor air flow. Try moving the tapes to an area that is more actively conditioned/heated.

    The first step is to identify the moisture source. There are 3 possibilities. 1.) Vapor emissions from the concrete slab. This occurs when water vapor travels upward through the slab. Its most common in older homes with missing vapor barriers. This can cause excess both moisture in the carpet and increased humidity in the air. The increased humidity can lead to mold growth on contents such as a sofa. 2.) Liquid water intrusions can have the same affect, but these are typically obvious .

    3.) The second possible cause is excess humidity due to poor ventilation and insufficient heat. Basements without adequate air flow and heat are prone to high humidity. Over time, this high humidity creates an environment conducive to mold growth.

    Action steps: Purchase a relative humidity gauge and monitor the RH. Pull back the carpet in a corner and look for signs of water intrusion on the concrete and the carpet pad.

    Mold in Walls, Part 3

    Youve probably realized by now what a power couple mold and moisture make. That is exactly what you should worry about when it comes to mold in the closet and how it can affect not only the clothes inside, but your health too. Since you wear clothes every day, wearing mold-affected ones can lead directly to health issues such as skin allergies. It is therefore very important to prevent mold on your clothes in the first place, in order to prevent any further skin allergies.

    Mold on clothes is often a result of damp clothes being folded and stored without a proper drying session. With enough moisture and food , its just a matter of time before your clothes receive unwelcome guests. Thats why its very important to ensure that each piece in your wardrobe is well dried before its folded and stored in the closet. If the weather permits, dry your clothes outside as much as possible. Fresh air and sunlight are your best weapon against mold in the closet.

    If you have a dressing room, then you should give it a full check-over for mold at least once a month, which includes checking walls behind the clothes, checking the ceiling and carpet. Ensure that there are no moist spots from a leaky roof, and if you have a window, keep it open as much as possible or install an air vent.

    In any case, keep the closet clean and avoid overfilling it at all costs. Wipe away any dust, and vacuum regularly, as well as checking the clothes that you do not wear often for any signs of mold.

    Monitor Indoor Plants Closely

    Anyone with indoor plants needs to remove mildew spores from them as soon as possible. If you leave plants inside your home with mildew spots on the leaves or the soil it could contaminate the air you are breathing and spread.

    Even if you have an outdoor garden, if you notice mildew growth on one of your cucumber plants, get rid of that plant before the mildew has a chance to spread. You don’t want to harvest recently grown tomatoes, forget to wash one of them, and take a bite without realizing that the mildew has already jumped from one plant to the tomato plant.

    What Is Green Mold

    Green mold is an umbrella term that refers to different species of fungi that grow in shades of green. It appears soft and fuzzy or powdery and can have different hues of green. You may have seen green mold on fruits, bread, and many other foods. However, green mold can also grow in wet areas of a home.

    Although many species of mold can grow green, the most common are Cladosporium, Aspergillus, and Penicillium.

    • Cladosporium is olive green and thrives on plants in particular, but can also grow on household surfaces like walls, cabinets, and carpets.
    • Aspergillus is the mold that typically grows on spoiled food like bread. It can also grow on nutrient-poor but moisture-rich environments like the basement.
    • Penicillium is famous for its antibacterial properties and is usually bluish-green. However, it can also emit mycotoxins that are toxic to both people and pets. Penicillium prefers colder environments like soil, but some also form on wet items in the home.

    However, these molds can grow in other colors as well, such as blue or black. Thus, testing is the only way to find out which type of mold it is. Thats not to say that you should always test the mold in your home to determine whether its harmful.
