How to get rid of black mold on the walls in an apartment forever

Black mold on the walls in the apartment, which many people simply do not notice in their homes. There can be small dark spots on walls, cracks and other surfaces, or huge “fluffy” mold spots. Such spots are black mold on the walls in the apartment, a dangerous fungal formation. We'll look at how to get rid of it in this article.

Black mold on the walls of an apartment is quite common. Many people live with it for years, suffering from chronic diseases and mycosis. Needless to say, you should get rid of black mold on the walls, ceiling or floor in your apartment as soon as possible. Ordinary black mold on the wall in an apartment can cause a colossal number of illnesses; such cohabitation is especially dangerous for young children.

Black mold (there may be other strains of the microorganism) belongs to a genus of mold fungi that can cause serious human illness . It is often used for industrial purposes to make citric acid, but in an apartment or house it poses a great danger.

In order to permanently get rid of black mold on the walls in an apartment with a guarantee, just call the phone number listed on the website. Our specialists will carry out a set of measures to remove black mold from the walls and ceiling of your apartment.

Why is black mold dangerous?

This type of fungus can cause serious health problems. In the stage of constant reproduction (in the presence of abundant moisture), it is found almost everywhere: on the surfaces of kitchen appliances, tables, toothbrush handles, and even in foods. It enters the lungs with air, which leaves a noticeable imprint on their condition.

If there is black mold on the walls in the apartment, then you can expect the following to occur:

Allergies;
Poor health and constant fatigue;
Lung problems: bronchitis, asthma;
Constant headache;
Colds;
Reduced effectiveness of the immune system;
Exacerbation of existing diseases;
Nausea and poisoning;
Diarrhea.

Children's bodies are especially susceptible to fungal spores. A child may constantly feel tired, weak, refuse to eat, literally attract colds, not play or show interest in anything.

Pets can also be the first to get sick when a microorganism appears. If there are changes in their behavior, pay special attention to the presence of mold.

You should not underestimate the black mold that appears on the walls of your apartment. Its spores are carried by air, which contributes to rapid spread throughout the entire housing area. When the first signs of black spots appearing on the walls in your home, you should immediately try to get rid of them. If this is not done, then in a couple of weeks the struggle will become more global in nature.

Black Aspergillus or black mold can be considered the most dangerous type of mold. It is he who causes the greatest harm to the human body and there are cases when it caused death.

What is mold and its danger to humans?

Mold that appears on walls is an accumulation of a large number of living organisms. The establishment of a mold colony begins with just 1 spore attaching itself to the ceiling, walls, furniture, fabric or other material. This requires favorable conditions.

The most optimal temperature for these microorganisms is +19…+21°C. In this case, the humidity level should be about 80%. If conditions become unfavorable, some of the colony may die, but most molds will survive. These organisms require a nutrient medium. It could be:

concrete;
tree;
brick;
plaster;
drywall;
varnished surfaces;
paper products;
textile;
leather, etc.

First, a small dot appears on the wall, ceiling or other surface. Subsequently, this outbreak quickly grows, occupying large areas. Mature mold begins to release large amounts of spores into the air. This contributes to the appearance of other foci of mold in the room. Most people have seen fungus on walls; few know why it is dangerous.

An increase in the area of mold growth and the number of spores in the air can adversely affect the health of residents. If there is mold in the apartment, people living in the room may experience:

slow exhaustion;
nosebleeds;
frequent headaches;
disruption of the gastrointestinal tract;
pathologies of the respiratory system;
rheumatic diseases;
allergic reactions;
dermatitis.

The risk group for developing severe diseases due to mold infection includes the elderly and children. In addition, mold is extremely dangerous for people suffering from immunodeficiency.

Inhalation of spores and contact with skin

The high content of mold spores in the air causes them to settle on a person’s skin and enter his respiratory system. This can cause the development of extremely serious conditions. Children and adults living in homes with moldy walls and ceilings are at increased risk of developing severe allergic reactions.

Inhalation of spores against a background of reduced immunity can provoke the development of fungal pneumonia. This condition is extremely dangerous, because... To eliminate microorganisms, highly toxic drugs must be used.

People who have not previously encountered an excess of fungal spores in the air may develop Quincke's edema and anaphylactic shock. It is believed that mold, when entering the body, can cause cell mutation and the formation of malignant tumors in the lungs. Black mold is considered especially dangerous in this regard.

Under some circumstances, spores deposited on the skin can cause the development of dermatitis and mycoses. People who use a bathroom with moldy walls often encounter a similar problem. In addition, these microorganisms can provoke malignant degeneration of skin cells.

Black mold in the bathroom

A humid environment is optimal for the development of Aspergillus nigra or black mold. That is why the bathroom in most cases becomes the center of its spread. Mold is also sometimes found outdoors, but in open spaces it is practically harmless.

More information about fungus in the bathroom is written in our article - how to get rid of mold in the bathroom.

Reasons for appearance

The main reason is constantly high air humidity, temperatures above +15 degrees and lack of good ventilation in the room. Also, the lack of periodic treatment of surfaces with cleaning agents creates an ideal environment for the development of fungus. Under such environmental conditions, its appearance is only a matter of time.

When you need specialist help

In most cases, the use of folk recipes and household chemicals does not bring results. Only the visible part of the plaque is removed, the mycelium remains deep inside, so after some time, colonies of the fungus reappear in the room. Mold can be removed forever only with the help of specialists. Stages of fungus removal by professionals:

assessment of area and degree of penetration;
evacuation of fabric products and other undamaged items from the premises;
destruction of all visible areas with fungus, including plaster;
Microwave processing;
application of fungicides;
disinfection.

It is very difficult to defeat black mold, but it is possible. It is important to provide indoor conditions that prevent the appearance and proliferation of fungus. If mold does appear, it is necessary to remove it as quickly as possible using professional or improvised means.

Black mold on the walls in the apartment

Sometimes it happens that black mold on the walls of an apartment can appear on walls, ceilings, and other surfaces of living rooms, such as windows.

Reasons for appearance on the walls

If everything is clear with the bathroom, then at first glance there are no obvious reasons for the appearance of black mold on the walls in the apartment. In fact, it is enough to not completely dry the carpet once or simply spill water on it for it to become a good breeding ground for fungus.

It can also multiply in wood and other materials that can retain moisture for a long time. The causes of fungus can also be:

Incorrect installation of plastic windows . If the rules for installing plastic windows are violated, the microclimate of the room may be disrupted. We devoted an article to this topic - Getting rid of mold on windows.
Poor heating . Moisture is not dried out, which accelerates the growth of mold fungi. Read our instructions on how to deal with humidity.
Rare ventilation. In this case, the concentration of pores in the air is maximum.

Installing plastic windows in an apartment makes the rooms literally hermetically sealed: air does not enter or exit. Under conditions of poor heating or increased humidity, such an environment is almost ideal for the growth of microorganisms.

When cleaning your apartment, pay special attention to the windows . It is near them that the fungus most often begins to appear.

How to eliminate the root cause

If mold appears in the apartment for reasons beyond your control, contact the responsible organization:

♦The problem is poor-quality heating, a neighbor above, a damp attic or “crying” pipes - write a statement to your management company. Utility workers must inspect the apartment, draw up a report on its condition, discover the root cause of mold formation and eliminate it within 45 days.
♦Load-bearing walls freeze - send a claim to the developer, and if there is no response, order an examination and file a lawsuit.

Professional products to combat black mold

They can be found on the shelves of hardware stores or purchased online. The effectiveness of use depends solely on the manufacturer and composition. The main thing is to strictly follow the manufacturer’s instructions and also take into account possible harm to finishing materials and the body.

Treatment of mold in an apartment using aggressive agents should be carried out using thick rubber gloves and protective equipment for the eyes and respiratory tract.

What to do in case of extensive lesions

Well, it is impossible not to highlight the method of combating fungus and mold, which is rightfully called the most radical and effective.

Those places where black mold has formed on the walls are completely cleaned and, if necessary, a layer of material is removed with a handy power tool.
In case of significant damage, all affected finishing materials are removed. After completely cleaning the walls, ceiling and floor, they are thoroughly dried and treated with special products.

Just keep in mind that this method of fighting is the most expensive. In fact, you will have to renovate the bathroom or another room.

Where to look for fungus?

Even if visually you cannot immediately detect traces of the presence of mold, you should look for it in places hidden from view.

It can be:

corners of walls in contact with the bathroom;
gaps between tiles;
places where plumbing fixtures connect to the walls;
under the baseboards in the area of the sink and bathtub;
on the ceiling;
under the rug on the floor;
in wood paneling;
in cups for hygiene items.

Having penetrated into other rooms, the spores, if they do not germinate, retain their ability to reproduce for a long time and are just waiting for favorable conditions.

It is impossible to completely get rid of them, but creating unsuitable conditions for their development is quite possible.

Prevention against black mold

To avoid becoming a victim of harmful fungi or to prevent their reappearance after they have been destroyed, you need to adhere to some basic rules:

Heating of all rooms in the housing must be sufficient to prevent excess humidity in each of them.
Monitor the number of indoor plants in the apartment and make it optimal (moisture when watering them makes the air humid).
Don't forget to ventilate the entire apartment. The fungus doesn't like this very much. When ventilating in cold seasons, you should not open the windows for a long time to avoid cooling the walls.
Hang laundry only outside the apartment. If you constantly neglect this rule, mold will certainly appear in your home soon.
When carrying out repairs, choose materials that are unable to accumulate a lot of moisture.
Insulate all surfaces that get very cold outside. For example, facade walls or the floor on a balcony.
Ensure good ventilation in the bathroom and kitchen.
To reduce the likelihood of black mold forming in your bathroom, install a good heated towel rail. It will reduce the amount of moisture and dry laundry and towels faster.

Tumor in the heart of foggy albion

In 2016, one resident of Britain, practically from its geographical center - Nottingham, published a story of the torment that befell her in the last years of her life. The article was published under the title “When I was dying.” I will retell it briefly and as accurately as possible:

“For many years I suffered from bouts of illness and a variety of continuous flu-like symptoms. I couldn’t stop coughing, I sweated at night, and felt physically exhausted. I was constantly treated with antibiotics and antihistamines. I had previously been diagnosed with asthma and would cough up brown plugs of mucus every morning.

The last attack of the disease occurred in March 2015, its intensity was very similar to the previous one, with constant pain in the right lung. A course of antibiotics did not give anything, they prescribed salbutamol and sent me for an x-ray. X-ray showed a mass in the right lung. They sent me for a CT scan. The cough got worse. The attacks turned into vomiting. It was impossible to breathe even with salbutamol. Based on the results of the CT scan, the doctors diagnosed “a greatly expanded malignant tumor, partial obstruction of the lung.” They sent me for a bronchoscopy, but it couldn’t be done due to breathing problems.”

The woman begins to prepare for her funeral and look for a place for the operation, calling paid cancer centers. She is visited by family, friends and relatives. She's supported, which is great. She is getting worse every day. Although nothing other than CT and X-rays indicates cancer. She is transferred to different institutions until the medical commission, together with the diagnostician, suspects the diagnosis based only on the images. After consulting in medical circles, they begin to suspect that it may not be cancer. New tests are ordered. These include analysis of immunoglobulin E for aspergillosis. The result obtained was so high that it was outside the rating scale. The woman was diagnosed with advanced and expanded allergic bronchopulmonary aspergillosis. The picture was so terrible that both the CT scan and the x-ray exactly matched the characteristics and appearance of a malignant tumor that occupied almost the entire lung.

Betsy was eventually saved, and she successfully transitioned from acute to chronic, leaving this world with a cough, the need for constant treatment and a terrible life experience. In her case, doctors concluded that the culprit was a compost heap in Betsy's backyard garden. But is it really that simple?

“Aspergillosis” is just a general name for a very immodest group of diseases caused by fungi of the genus Aspergillus. For the most part, the disease is most typical for already sick or severely weakened people. These are everyone who has suffered or is still suffering from a wide variety of lung-related diseases: from tuberculosis and chronic obstructive pulmonary disease to asthma and severe allergies. In Betsy’s case, she acquired aspergilloma; in other words, fungal mycelium grew in her lungs. In order for fungi to grow in the bronchus or lung, it is not enough to simply inhale mold spores. You do this all the time anyway. In order for them to take root, it is necessary to have damage (in the form of a granuloma, for example). And then, once in the cavity of the granuloma, abscess or cyst, the spores germinate and aspergilloma begins to grow.

The process can be very long; the tissues of the bronchi and lungs will gradually deteriorate, becoming involved in the formation of detritus - dead cells at the base of the fungus. The patient can simply cough for a long time, until his condition gradually deteriorates, the attacks become stronger, mucus and sputum appear, it becomes greenish, flakes, blood, pieces of bronchi and fungus are added. Aspergilloma itself can grow almost anywhere, but the lungs come first due to the largest number of spores getting there, the second ear canal. But if the spores enter an organism deprived of protection, they can be carried away to the liver and kidneys. Where, with low or impaired immunity, something will definitely grow. Jacques was unlucky with his maxillary sinus.

In the past, it was relatively difficult to grow mushrooms in yourself. Laboratory observations in large cities such as San Francisco revealed 1-2 cases per 100,000 population (data for 1992-1993). But since the advent of immunosuppressants, which began to treat various types of allergies, and the increase in organ implantation, more than 15,000 cases per year of invasive forms of aspergillosis began to be recorded in the United States alone. If this is not enough for you, add another 6 million people with the allergic bronchopulmonary form. This is when the immune system, on the contrary, reacts too actively to spores. A cough appears, injuries, scars...

Professional removal of black mold

To begin with, it should be noted that the involvement of specialists allows us to obtain a comprehensive solution to the problem. Unlike self-treatment of walls with means, they carry out a complex of actions:

Complete analysis of the object's condition. Foci of fungus are detected. For this purpose, a thermal imager inspection or a mycological examination may be carried out.
Choosing the optimal method for treating surfaces and drawing up a list of actions to eliminate the causes of mold development.
Carrying out operations agreed with the owner of the apartment.
Checking the work.

Surface treatment method

Different companies can use their own technologies. They are often determined depending on the current situation. But in most cases, the process of eliminating black mold on the walls and in the bathroom goes something like this:

Problem areas are wetted with water to prevent the spread of spores during cleaning.
Special solutions are applied to the surface of the coatings. After they dry, the process is repeated several times.
Using special technical devices, the fungus is removed. In this case, the paintwork, wallpaper and even plaster are removed (the plaster can even penetrate into its structure). In some situations, concrete walls can even be milled.
Defects in premises are eliminated, promoting the formation of an optimal environment for the growth of microorganisms. Cracks in walls, near windows, etc. can be covered up.
Disinfection is in progress.
The affected areas are well dried.

Microwave method or heating and drying walls from mold

This method of eliminating mold can be considered the most effective and safest. Its essence is to warm the infected areas to a high temperature. Technology Features:

Size of treated area: 50x50;
Warm-up depth: 30 cm (+ - 5 cm);
The strength of the temperature effect is 65-70 degrees.
The effectiveness of the method is due to the ability of the fungus to withstand temperatures up to 60 degrees. It is also worth considering that when operating a laser pyrometer, you can accurately control the level of heating.

The advantages of the microwave method include:

Ability to process any surface;
Fast completion of work;
Processing even hard-to-reach places;
There are no chemicals;
Temperature passes through different materials.

Fighting black mold in the bathroom and on the walls of other rooms is simply necessary. Its presence can cause serious illnesses and a significant deterioration in the body’s condition.

At the initial stage of its appearance, you can use improvised means and try to get rid of the dangerous fungus yourself. But the most correct and rational way out if there is mold of black or other colors is to contact a specialist.

Only professionals will be able to solve the problem for a long time and make your home absolutely safe to live in. Moreover, the cost of their services is affordable in most cases. Just when choosing a company, be sure to ask about the possibility of using the technologies described above (microwave and others). This will guarantee that you order services from truly professionals.

Types of black mold plaque

Black mold is considered the most dangerous to humans. It often causes the development of serious illnesses. There are several types of microorganisms that lead to the appearance of black deposits on surfaces in residential areas.

Aspergillus black fungus

This microorganism is a saprophyte that lives in conditions of high humidity. They are a black coating. It most often occurs on walls and ceilings in bathrooms, kitchens, toilets and swimming pools. They can form colonies in air conditioners and even washing machines. These microorganisms release a large number of spores, which quickly scatter throughout the room due to this mold. Clothes, furniture, books and other items may be affected.

These fungi can cause the development of meningitis, bronchial asthma and myocarditis. Inhalation of large quantities of fungi can cause severe poisoning. Aspergillus nigra often leads to the formation of pulmonary aspergilloma.

Aspergillus fuming fungus

This microorganism is highly resistant even to strong temperature changes. This mold gets its name from the fact that it causes black wool to appear on the surface, and when touched, a smoke of spores appears.

Fungi can survive at -53°C. Most often they infect vegetables and fruits, but they can also establish colonies on surfaces in residential areas. The toxins produced by these organisms are extremely dangerous. They can suppress the immune system and destroy red blood cells. Inhalation of spores can cause aspergillosis.

Alternaria alternata fungus

This mold produces large numbers of spores as it grows. Colonies of these fungi appear as flat spots of dark gray or black color with a greenish tint. Most often, this mold parasitizes on dead plants, but it can also appear on other surfaces. When growing on grains, toxic substances released by this microorganism can poison the product, making it unfit for consumption. This fungus can provoke bronchial asthma and dermatitis.

How to prevent mold?

This uninvited guest feels comfortable in a room where there is absolutely no ventilation and drafts in conditions of high humidity - from 80% and a temperature of 20⁰. Based on this, it is necessary, first of all, to create an environment in which mold cannot develop in principle.

To maintain constant humidity levels in the bathroom, you do not need to close the door tightly. If this measure is not enough, you will have to arrange ventilation. You can install a door with special holes for ventilation or drill them yourself, then decorate them with decorative rings.

The door model with holes equalizes the temperature inside the bathroom. Ventilation holes come in the form of circles or rectangles. They are performed in several zones or one and are masked with a decorative lattice.

A more effective way is to install a fan in the air duct. The hole is sealed with a ventilation grill. Switching on and off can be done using the light switch.

The best option is to install a hygrometer and connect it to the fan via a sensor. Once the humidity reaches the upper limit, it will turn on the fan. When the humidity value drops, the device turns on again.

You can buy a ventilation grill and install it yourself, but then the integrity of the door leaf is compromised.

If you follow all our recommendations, the issue of black mold will no longer bother you.

Types of House Mold

Most often, mold fungi of the following varieties settle in the apartment:

Green mold . It usually appears on food products, but can also affect some building materials, such as bricks;
White mold . Covers the surface of the substrate in flower pots. It starts when there is constantly water in the trays of the flowerpots;
Blue mold . It mainly affects wood; in addition, it destroys the paintwork of wooden structures;
Black mold . The main enemy of homes and people, the most common, dangerous and difficult to remove type of mold, which not only destroys building materials, but also causes allergy attacks, and also provokes the development of pulmonary diseases.

Causes of dangerous fungus

Some people mistakenly believe that mold cannot be removed. But if you correctly determine the reasons why it appears, eliminate it, and also take preventive measures, then there is a chance you will never see black plaque in your home (walls, bathroom, refrigerator, bread) ever again. Often, when ridding a home of mold, people mistakenly make do with half measures: for example, they scrape off the plaster and then treat the surface with antiseptics. But this turns out to be not enough, and the attack returns again to places that are comfortable (warm and humid) for its existence. That is why you should first look for the reason.

As mentioned above, in the modern world the problem of fungus not only has not gone away, but has also worsened due to the widespread use of modern materials in construction. Mold spores especially like to multiply on plasterboard sheets. Why? Both plaster and cardboard are capable of perfectly absorbing and retaining moisture, which fulfills at least one condition for the development of fungus. Although manufacturers provide for this problem by adding antiseptic additives to gypsum panels, even such a measure is not able to prevent the growth of fungal spores if high humidity is maintained in the room;

The widespread use of plastic windows and doors in housing construction aggravates the problem, if only because their tightness is aimed at blocking the flow of air from the outside in order to maintain a comfortable temperature inside. Thus, water entering the home evaporates more slowly, which, coupled with heat, creates a favorable environment for fungus;
Construction errors (eg, damaged exterior walls, poorly installed flashings, drainage problems) that lead to increased humidity in the home can also cause mold to develop inside the building. Only a thorough inspection and correction of damage should precede the treatment of the premises;
Poorly designed ventilation is the scourge of old buildings, so when in a no longer new house with an ill-conceived ventilation system they also replace old windows with double-glazed windows, the problem only gets worse, and new opportunities arise for fungal spores.
