WHAT IS WHITE MOLD?
Mold is a fungus with thousands of distinct subspecies, which is one thing to keep in mind. The Mold Medic: A Story of Industrial Health, by Michael Rubino, President of All American Restoration.
With over 100,000 species of mold identified so far, this fungus can come in a variety of colors, shapes, and textures,’ according to an Expert’s Guide on Mold Removal (Amazon).
Depending on the type of surface it has infected, white mold is a powdery fungus made up of numerous fungal species that may appear white, green, or grey. White mold, like other molds, flourishes in damp places such as bathrooms, crawl spaces, basements, and leaky walls.
Molds can quickly spread if they have a constant food source, such as cellulose (which is made up of starch and sugar), which is abundant in most wood products. Molds are common on floors, beams,wood furniture, decks, and ceilings.
In households with damp and humid conditions, white mold is a frequent sight. When surfaces have been left wet for a long period, such as carpets and wallpaper, it is simple to identify because there will be a distinctive white film on them. Some individuals think that white mold is hazardous, however the facts do not prove this.
Health problems or even structural damage can result from prolonged exposure to white mold. To avoid these issues, it is critical to understand what causes white mold and prevent it from developing.
This page will cover everything from the most prevalent forms of white mold to ways to prevent them from causing harm, as well as how to stop them.
White mold in basement concrete
The distinctive white cottony mycelium of the mold that grows on the surfaces of water-damaged organic materials is easily recognized after flooding or chronic dampness.
Because they look a lot alike, efflorescence and white mold in basement concrete are frequently confused. Efflorescence is practically similar to white mold, even to the inexperienced eye. Spalling and deterioration of the concrete may be caused by moisture and dampness flowing through basement concrete.
Mold is not present on the efflorescence or white deposits. Yet, the efflorescence’s presence of moisture is evidenced by the evidence.
Mold can and does grow in the presence of moisture. Efflorescence, on the other hand, indicates that there is a moisture issue and hence most likely mold development on organic materials.
White mold thrives in basements. White mold thrives in darkness, humidity, and warm weather.
Moreover, since the basement is gloomy, white mold growth may go unnoticed until it has progressed to a severe level of infestation.
White mold may develop on certain areas if you frequently do your laundry in the basement or store a large number of wet items.
Hidden places, such as behind furniture or in the corner of the floor, are possible growth locations. As a result, to avoid mold from forming, homeowners must put money into proper basement management.
At other dark places in the home, the same problem may arise. White mold can thrive in a variety of locations, including the ceiling, under the sink, or behind the walls. If there is undetected leakage or a plumbing issue, the problem may get worse.
Which Molds Are White?
Mold is a fungus that can be found all over the world. Mold comes in a variety of shapes and sizes, with some being white in color. Penicillium (which may also be yellow or green), aspergillus (which can also be yellow or green), and cladosporium are three species that are frequently seen in houses.
In general, determining which kind of mold is growing in your home isn’t really required; all types of mold may harm the health of your family and may cause problems.
What does white mold look like?
Since the spores are minute when white molds are first developing, they’re difficult to spot. White molds will appear as white spots on a surface when the colonies develop.
The spots might have a powdery feel, a fuzzy look, or even a filmy appearance. White mold is more dangerous since it may develop inside organic materials rather than just on the surface, despite seeming to be similar to mildew at first. White mold can be seen growing on attic wood rafters in the photograph below.
The lack of spore pigmentation gives white mold its distinctive appearance. The kind of materials used to create the mold often results in this. White mold does not darken as it develops, unlike most fungus outbreaks. Cladosporium or aspergillus can be found in white mold samples, according to lab testing.
It’s difficult to tell the difference between this mold and ordinary mildew. White mold on the walls is similar to mildew, which only develops on the surface and is less harmful. White mold, unlike mildew, destroys wood, sheetrock, and even furniture by penetrating through them.
Where in homes is white mold most prevalent?
Mold thrives in environments with a food source and is especially fond of dark, wet places.
Attics, which contain plenty of food sources such as wood and insulation, are an ideal environment for white mold. Mold can get the moisture it needs from leaky roofs, condensation from changing temperatures, leaky pipes, and/or insufficient ventilation.
Because of the confined spaces in attics, removing mold might be difficult. We recommend going up into your attic from time to time to make sure there isn’t any white mold or a musty odor.
Concrete walls, wooden floor joists, and items kept there, such as clothes, are frequently infested with white mold in basements. Water often seeps into the ground through basement walls, creating a mold-friendly environment.
Condensation may be caused by cold outdoor air that comes into touch with hot indoor air in basements, making it an ideal breeding ground for white mold.
White mold in a basement and crystalline efflorescence are two terms that are often used interchangeably. Efflorescence isn’t a kind of mold, and both substances thrive in humid climates. When moisture travels through concrete, efflorescence is a salt deposit left behind.
Spray the impacted region with water to determine whether it’s white mold or efflorescence mist. The salt will effloresce away if it’s efflorescence. Mold testing should be done if you’re still concerned, since mold may spread throughout the walls and floor joists.
White mold in your home is likely to be found in crawlspaces such as basements. Moisture in crawlspaces may be caused by leaksy pipes, shattered downspouts, gutters, foundations cracking, insufficient ventilation and other factors.
Because cardboard boxes and other organic materials are a food source for mold, it’s also best not to use your crawlspace as storage. While removing and remediating the mold, the source of the moisture must also be addressed.
Furniture and wood
Wood, sheetrock, and furniture are all porous surfaces that white mold can penetrate. White mold can be found on the walls of attics, basement floor joists, and crawlspaces, as well as on wooden furniture. It’s a common sight on wood surfaces.
Mold removal on wooden furniture is possible if you find it numerous times, but more porous materials like fabric on chairs or sofas will need professional cleaning. The picture below shows white mold on wooden furniture.
Why does mold grow on concrete?
Mold requires food and moisture to grow. The thin layer of dust that settles on the surface provides plenty of nutrients, despite the fact that concrete isn’t a direct food source. It will be difficult to eliminate the food source for mold unless you wipe down your concrete on a regular basis.
The temperature requirements for mold are also the same. It will grow happily at any temperature that you prefer to live in. Moisture is a big factor. When it comes to mold, this is the one thing we can change. You have three options for excess moisture with concrete:
Liquid water intrusion
You’ve essentially created a huge empty bowl surrounded by water if any part of your home is below grade. The water will eventually make its way through the concrete if there isn’t enough drainage or a sump pump. It isn’t necessary to have large cracks or holes.
Large volumes of water can be forced via hairlines cracks due to hydrostatic pressure. Mold growth can be caused by liquid water intrusions, but it is normally limited in extent.
Humidity based mold growth
The insulator property of concrete is weak. The chilly surface of a concrete wall can cause condensation during the winter months when the temperature drops. The higher surface moisture encourages mold development over time.
Mold growth on concrete is usually diffuse and covers a broad region due to humidity.
Concrete alone does not provide enough nourishment for fungal development. Unfortunately, dust quickly collects on the surface, which is not particularly useful since it happens nearly everywhere in a structure.
The majority of mold food sources are found in this layer of dust. As a result, mold development is possible unless the actual is kept immaculate.
Mold will not grow without sufficient moisture, even if the concrete is completely covered in dust. Controlling the moisture, rather than the dust, is generally much more preferable in most situations. Airborne moisture (reducing humidity) and liquid moisture (flooding, vapor drive) are both addressed in this way.
IS WHITE MOLD IN THE BASEMENT DANGEROUS?
The truth is: not always, or not for everyone, but you don’t want to find out. ‘Everyone reacts differently to mold exposure,’ Rubino emphasizes. Another may experience over 30 symptoms while only having a runny nose once in a while.”
White mold is a health risk, despite the fact that mildew and other kinds of mold are less dangerous and more bothersome. Mold-induced asthma, allergic fungal sinusitis, allergic bronchopulmonary aspergillosis (a lung illness that can be fatal to those with asthma or cystic fibrosis), and hypersensitivity pneumonitis may all result from inhaling white mold spores over a long period of time.
Factors such as species of mold, genetics, immune system status, and length of exposure are some of the factors that play a role, says how the mold in your home may affect you. People exposed to molds like Aspergillus may experience symptoms and illnesses, such as Aspergillosis.
That’s why it’s important to remove all mold growth quickly and properly to protect your indoor environment and ensure that you and your family are safe.’
To put it another way, since mold isn’t any more or less dangerous than black mold, but you are more likely to be harmed by its detrimental effects on health, it should be handled as seriously as black mold.
Let’s look at the health effect of mold in greater detail
Allergic molds, as well as asthma, cause allergies. Your respiratory system reacts when you come into touch with such molds. Mold allergy affects around 20% of people and can cause rhinitis, also known as hay fever, in those who are allergic.
Congestion, rash, and itchy eyes are common side effects, but severe side effects include swelling, difficulty breathing, vomiting, diarrhea, and mental confusion.
Mold-related illnesses may be more severe. These molds may have a serious impact on the health of individuals with limited immune systems. Skin irritations, nail infections, and athlete’s foot are minor symptoms; severe symptoms include life-threatening organ infections.
Mycotoxins are very harmful to humans and are released by toxigenic molds. Ingestion, inhalation, and direct touch (touch) are all pathways of exposure to these molds.
Toxic molds may cause symptoms ranging from irritation to chronic illness, depending on the person, the length of exposure, and the route of exposure. Hormonal problems, liver damage, neurological conditions, and cancer are just a few of these deadly illnesses.
Allergenic or harmful molds account for the majority of white molds. You should always contact skilled professionals about how to safely and effectively remove the mold toxin from your house, no matter what sort of mold you discover growing in your house.
HOW TO TACKLE LARGE AREAS OF WHITE MOLD IN A BASEMENT
You have a huge-scale mold removal job that needs to be finished by a professional if you’re dealing with an region bigger than a single wall. ‘Choose a mold inspector to come in and assess the condition of the home,’ Rubin advises for larger-scale projects.
This person should spend a few hours inside, using a number of measuring techniques. If the problem is fixed and all contaminants, including mycotoxins and bacteria, have been removed, locate a remediation team to restore the source of the problem, cleanse the mold, and eliminate all traces.’
White Mold vs Mildew and Efflorescence
Mildew, which has a similar white color, is occasionally confused with white mold. Mildew, on the other hand, is seldom seen on non-plant surfaces and does not harm materials. White mold, on the other hand, can damage the surface of porous materials such as wood and drywall.
White mold is frequently mistaken with efflorescence, which is a material. Salty water seeps through concrete, brick, or stone, causing a salt deposit. The white crystalline material, similar to this kind of mold, is left behind when the water evaporates.
Efflorescence, on the other hand, is non-poisonous and won’t spread or develop if it isn’t present.
Look at the affected surface to see if a material is a white mold or efflorescence. It’s efflorescence if it’s masonry. Also, if it dissolves in a drop of water, it’s not mold. Lastly, if the substance breaks into a fine powder when squeezed between your fingers, it’s efflorescence.
