Why does high humidity occur in the house?
Moisture inside a home appears in two ways: it penetrates from the outside or accumulates from the inside. The first case indicates mistakes were made during construction work, the second situation is typical for rooms with excessive condensation formation.
External causes of dampness in the house:
- the presence of unclosed gaps in the roof, through which precipitation (snow, rain) periodically penetrates into the home;
- gradual destruction of the foundation due to the lack of tide, as a result of which moisture accumulates under the floor covering;
- the formation of multiple cracks on the walls of the building;
- the use of a material (for example, plastic) for cladding a house that does not “breathe” and contributes to the accumulation of moisture inside the building;
- improper arrangement of supply and exhaust ventilation;
- close occurrence of groundwater in the absence of high-quality waterproofing from the outside and inside of the building.
Important! Dampness in a newly built wooden house often appears as a result of the use of poorly dried wood during construction.

Fungus on the floor and mold under linoleum, laminate
Often unwanted moisture accumulates under linoleum. It is there that all the conditions are created for the development of mold, which is almost impossible to get rid of completely and the coating has to be changed.
In this case, it is advisable to observe the following:
- Under no circumstances should old materials be laid on floors affected by mold.
- The fungus often spreads to the walls, so you should cut off the lower part of the wallpaper adjacent to the baseboards;
- When installing a new coating, it must be treated with antifungal drugs.
Why is dampness dangerous?
Excessive moisture inside a home has a negative impact on the health of permanent residents. Elderly people and young children suffer the most from fungus and mold. The most common consequences of prolonged exposure to a damp room are:
- development of dermatoses, mycoses;
- allergic reactions;
- the appearance of asthmatic attacks;
- frequent colds;
- headache;
- nausea;
- constant malaise;
- sleep disturbance;
- dizziness.
Attention! Increased moisture levels in the home often provoke exacerbation of chronic diseases in people. Therefore, it is extremely important to maintain an optimal humidity of 40-60% in the house.

How to eliminate damp smell
The unpleasant smell of dampness often comes from furniture, things, walls, floors, and ceilings. You can remove it using special and folk remedies:
- Air ionizers and other preparations designed to eliminate unpleasant odors in rooms. They are sold in construction stores or department stores.
- Essential oils. They must be added to clean water, then rinsed off floors and other surfaces.
- Vinegar with water. It is recommended to mix these components in equal proportions and spray the resulting solution in areas with the most pronounced mold smell.
- Soda. Prepare an aqueous solution (1 tablespoon of soda powder per 200 ml of liquid), treat all places where the fungus is present.
- Hydrogen peroxide, bleaches. Apply directly to mold affected areas.
- Chlorine-containing products. Add to water, which is then used to wash floors, wall tiles, and other surfaces suitable for wet treatment.
- Ammonia. As part of an aqueous solution, it is generously applied to problem areas.
Important! The smell of dampness in an apartment or house indicates the presence of fungus in the home. To remove an unpleasant odor, its source must be destroyed.

Base for laying tiles
When covering the walls and surfaces of showers, bathrooms and swimming pool rooms with ceramic tiles, experts recommend using moisture-resistant gypsum boards (GCP) as the basis for this.
Moisture-resistant gypsum boards differ from ordinary plasterboard boards in that they contain antifungal and hydrophobic special additives.
How to get rid of humidity at home
In a private building, it is much easier to eliminate excess moisture than in an apartment, where the appearance of mold is often caused by a violation of the construction technology of the entire building.
Laying waterproofing
Before dealing with dampness inside the building, you need to tackle the basement (if there is one). The use of concrete-containing dry mixtures will help normalize humidity. Using the latter, you need to plaster the area under the floor, seal all the cracks and crevices. For air outflow, it is necessary to install a hood with access to the street.
Then you need to move on to waterproofing the entire house. To do this, carefully plastering the external walls is performed. In a wooden building, the gaps between the logs are sealed with tow or glass wool.
It is important to pay special attention to the roof, even if there are no visible leaks. To prevent moisture from penetrating through the roof, its interior should be finished with any waterproofing material.
The next stage is the implementation of internal waterproofing of the building. Drywall is perfect for all rooms, but for the bathroom it is important to use a moisture-resistant type of such material or plastering.

Redecorating
How to remove moisture in a house if it is not possible to carry out major repairs? In such cases, it is worth trying to perform surface repairs.
Procedure:
- Remove wallpaper damaged by dampness.
- Clean the surface from fungus, treat with an antiseptic (for example, copper sulfate).
- Wait a few days until the room dries out, or use a heater.
- Apply a layer of primer to the walls, and then plaster them or cover them with plasterboard.
- Finish the wall surfaces (hang wallpaper, paint).
It is advisable to replace the floor covering, even if it is not badly damaged, with a new one.

Mold control products
There is no single correct and effective solution to get rid of mold on the walls once and for all. In one case, one remedy will work perfectly, but in another, it will be powerless. In general, the arsenal of each owner of a private house usually consists of two types of tools:
- specialized chemicals;
- folk
It is important to remember that any available means are good for cleaning the surface from microorganisms, but only consistent adherence to all stages of wall treatment will allow you to protect it from re-infection.
How to reduce indoor humidity: preventive measures
Since it is not at all easy to remove dampness from the house, it is recommended to prevent excessive accumulation of moisture inside the home and follow these instructions:
- Ventilate the rooms periodically. It is possible to reduce the humidity in a room by regularly ventilating it. It is advisable for the kitchen window to be slightly open at all times, especially while preparing food. This is due to the fact that vapors emanating from boiling liquids condense on all surfaces, quickly absorb into the walls, and provoke the appearance of fungus.
- Eliminating sources of moisture. Often the main culprit for the spread of mold inside the house is wet laundry. If the premises are not equipped with a high-quality ventilation system, drying things in them is prohibited.
- Heating. In winter, heating devices should be turned on at the required power to keep the rooms warm and comfortable. Savings often lead to irreversible consequences: the growth of fungus on all surfaces, the appearance of mold even in cabinets.
Advice! In summer, windows should not be completely covered with curtains. Then the sun's rays will freely penetrate into the home, warm and dry it.

The best drugs for dampness
There are many industrial products designed to combat high humidity in the home. Each of them has positive and negative sides and is used under specific circumstances. The most effective drugs are considered to be the following:
- Biocide. Eliminates fungus outside and inside the building and is characterized by significant effectiveness. Its main drawback is its high cost (800 rubles per 10 liters).
- Fongifluid. A ready-made solution that can be applied to almost all surfaces and coatings. Consumers note low product consumption and affordable price (550 rubles for 2 liters)
- Dali. A highly effective drug with a low cost (150 rubles per 0.6 l). It can be applied to all surfaces, including wallpaper and tiles.
It will be much easier to get rid of dampness in a private house or apartment if you initially accurately determine the source of its formation and spread. You can cope with this task yourself; in difficult situations, you should use the services of specialists.

Causes of mold
We have already noted above that the real “paradise” for mold is damp places. Dampness also does not appear on its own initiative and has a specific reason that determines its appearance. Let's look at what these reasons are:
- increased air humidity
- if you often do wet cleaning and dry clothes in the house, then the humidity will always be higher than normal; - cracks in the walls
- they wanted to put up wallpaper so quickly that they safely skipped all the stages of preparing the walls, as a result, spores appeared in the cracks, which continued to spread throughout the entire wall; - condensation on pipes
- if the pipes “sweat”, this is not good: call a specialist and determine the real reason for this, otherwise mold will invariably settle in your home, right next to such pipes; - clogged ventilation
- we love plastic windows so much that do not allow air to pass through, and we completely forget that the hood needs to be cleaned from time to time, otherwise problems cannot be avoided; - sudden changes in temperature
- sloppily designed insulation can play a cruel joke on you at the very first frost.
As they say, it is better to “be on the safe side” than to hastily eliminate the bad influence of microorganisms on your body or your child’s later.
