Dampness in the cellar is a serious problem, as it quickly leads to the formation

If preservation or food stocks (potatoes, onions, pumpkin, beets) are stored in the room, this will lead to their deterioration.

Therefore, everyone should know a couple of simple rules on how to get rid of dampness in the cellar using folk methods or the latest advances in technology.

Causes of dampness

Dampness in a room is usually referred to as the accumulation of moisture in the form of condensation on the walls and ceiling. It manifests itself by blackening of the corners and the formation of mold on the walls, the appearance of an unpleasant smell in the room. You need not only to know how to remove dampness in the basement, but also to understand why it is formed in order to deal with the cause, and not the effect, in the first place. The provoking factors for the formation of excess moisture in the cellar are:

A lot of trouble causes condensate in the basement, which settles on the walls and ceiling in the form of dew. This happens as a result of the temperature difference between the street and indoors. The walls in the winter freeze through, so under the influence of heat from the inside, dew forms.

In the summer, everything happens exactly the opposite, dew forms on surfaces due to the ingress of warm air from outside. In the off-season, the basement is rarely damp.

Do I need to deal with moisture

Not everyone is looking for ways to dry the cellar in a garage or house, believing that mold and high humidity in such a room are the norm. But a dry and dark basement is considered the norm, it is in it that you can store supplies for the winter and vegetables for eating without fear for your health. The indoor humidity is measured using a hygrometer. The indicator should always be at the level of 85-95%.

You can check the level of moisture accumulation even with a simple glass of water. To do this, you need to put it in the refrigerator for a day, and then put it in the basement. If, under the influence of heat, drops formed and quickly dried up, the humidity in the room is too low, if they turned into large drops and glass in small streams, then we can talk about high humidity. Normally, the walls simply remain misted.

Excessive accumulation of moisture affects the air in the room, making it heavy and unpleasant, and also threatens with the following troubles:

• Spoilage of all food and things that are stored indoors.
• The appearance of mold and fungal formations that can cause respiratory diseases even with a short stay in the room.
• Destruction of walls, finishing material, decrease in the stability of the load-bearing structures of the basement floor of the building. This usually leads to the need for costly repairs.

To prevent such negative consequences, you should adopt a few simple ways to dry the garage from dampness, or the basement if moisture has begun to accumulate in it.

Ways to deal with high humidity

The fight against excess moisture in the cellar should begin by establishing the cause. This allows you to take the right measures to improve the microclimate in the basement, garage or cellar. Today on the market you can find a lot of modern means for waterproofing, as well as suppressing the growth of mold. However, they themselves are ineffective without the arrangement of high-quality ventilation and a water drainage system.

Better ventilation

Proper air circulation in the basement is the key to dryness in the room and the absence of fungus. The ventilation system consists of supply and exhaust. For each of them there are requirements for placement:

So that the ventilation shafts do not freeze over in the winter, they are insulated, and also supplied with valves and condensate collectors. With their help, you can regulate the flow of air if it is freezing outside.

The cross section of pipes for ventilation is selected based on the volume of the room. If the shafts are already installed narrower than required, a small fan can easily correct the situation. If the device is equipped with humidity sensors, then they turn on automatically.

Lower groundwater

The problem of dampness is especially acute if the cause of its formation is the penetration of groundwater into the premises. Since this often causes premature destruction of the structure. To prevent this from happening, a number of measures are being taken to strengthen the foundation and pump out groundwater. They are as follows:

• The foundation is dug around the perimeter. The depth should be approximately 20-30cm.
• Drainage is organized along the formed perimeter.
• The base is strengthened, external and internal waterproofing is installed.
• The room is thoroughly dried.

It is quite difficult to independently carry out the entire complex for the removal of groundwater. Therefore, it is much easier to attract specialists for this, who will carry out all the actions efficiently and quickly. Usually their services are cheaper than correcting all the mistakes made in the process of arranging by amateurs.

Elimination of capillary moisture

If heavy drops are constantly collected on the walls, then this indicates the penetration of liquid from the outside. You can exclude its hit by one of the popular methods:

The latter option is especially relevant if groundwater enters the room along with capillary moisture. Also, builders often use pieces of dense material impregnated with bitumen, linoleum, waterproofing or roofing material as insulation. Compositions can only process problem areas from which moisture oozes, or entire walls.

Arrangement of external waterproofing

If moisture gets inside the room due to the poor condition of the external waterproofing, then first of all it is necessary to inspect the house for “weak spots”. Particular attention is paid to the blind area, drainage system, downpipes, slopes. It is necessary to pay attention to their condition and functionality. If the drainage system, it is necessary to make a comprehensive installation of slopes and downpipes. After that, proceed to the protection of the outer walls:

• The old blind area is removed.
• A pit is made about 50 cm wide, if you count from the outer wall of the cellar.
• The wall is thoroughly dried (it is better to do this in good weather).
• A waterproofing antifungal composition is applied.
• The wall is coated with bituminous mastic, clay or concrete with liquid glass additive.
• A blind area is made of roofing material (the sheet is fixed 0.5 m above the ground level and is displayed beyond the edge of the outer wall of the basement).
• Yama falls asleep.

It is best to do external insulation along with the drainage system. After the work done, they begin to dry the basement and arrange the internal waterproofing, in the process they use a building material with a low ability to pass moisture.

Prevention of condensation

Preventing the formation of heavy drops on the walls is much easier than dealing with the problem from time to time, resorting to radical methods. Therefore, every basement owner should know a few simple ways to avoid dampness in the basement:

It is necessary to take care in the repair process not only of the basement, but also of the rooms located above it. To prevent the penetration of moisture, a high-quality vapor barrier is arranged between them.

How to urgently dry a storage room and what to do to keep it always dry in the future

“My cellar wept. There are constant drops of water on the ceiling, the wooden hatch is wet through, the carrots and cabbage have long since rotted, the potatoes are still holding on,” a FORUMHOUSE participant writes. Syava_1.

A "weeping" cellar is always a big problem. How to dry it urgently and what to do to no longer face increased dampness? We tell what the participants of our portal do.

For high-quality storage of vegetables, the temperature in the cellar should not be higher than +5 degrees, the air should be clean and fresh, but without drafts.

BogAD Member FORUMHOUSE

The Russian scientist A. T. Bolotov wrote more than two centuries ago that there should be no damp and musty air in the room where vegetables are stored - the vegetables will rot. And at the same time, he notes that there should be no draft, because it will dry out our vegetables.

But you can’t overdry the cellar either, there is even data from observations by FORUMHOUSE participants of their cellars, which indicate that excess moisture is not as dangerous for storing vegetables as excessive dryness.

The humidity level for optimal storage of stocks should be 70-80%.

Having measured the temperature and relative humidity in the cellar with a thermometer and hygrometer, we bring them into line with the desired indicators (recommendations BogAD):

• If it is cold in the cellar (the temperature in winter is below +2 0 C), we insulate the basement or work.
• If it is too warm in the cellar (the temperature is above +5 0 C), we lower it by isolating the cellar area from heat sources. Provide adequate ventilation and isolate the area from heat sources.
• A slight excess of relative humidity is corrected by ventilation.
• With a significant excess of relative humidity (abundant condensate on the walls and ceiling), we make waterproofing, and then we are already engaged in ventilation.
• If the air is musty - the ventilation system does not correspond to the area or is absent, we eliminate this omission.
• If drafts are walking around the cellar, the ventilation system also needs to be upgraded, it may be enough just to add a damper to the inlet.

Based on the diagnosis that was made to the cellar, a work plan is drawn up. But there are situations when a stored crop needs emergency help, and there are several ways to provide it.

The picture on the left shows the cellar dehumidification scheme, which FORUMHOUSE participant DoctorBo I saw it in some book from Soviet times.

DoctorBo Member of FORUMHOUSE

The light bulb warms the air, it rises through the open basement hatch.

On the right picture - an improved, modernized scheme, in which the light bulb is located not under the hatch, but under the chimney. This scheme is better, especially when we are not dealing with a cellar, which is located under the building - then the air does not go into the house, but outside it.

Variants of this method, successfully tested by the participants of our portal:

1. A light bulb from the refrigerator is inserted directly into the pipe, 5-7 cm.
2. If the light bulb does not fit in the pipe.

Glebomater Member of FORUMHOUSE

Put a lampshade on the bottom of the pipe, there is a light bulb in it. The light bulb is on, heats the air in the lampshade, the draft starts to work.

Instead of a light bulb, you can use a candle (to avoid fire hazards, put the candle in a tin). It is better that the candle is as close to the floor as possible, and to improve traction, the exhaust pipe is lengthened by building a tin link on it.

A burning candle or light bulb accelerates air circulation, intensively ventilates the cellar. The musty atmosphere of the cellar is replaced by fresh air, and the cellar is usually completely dry within a few days.

If we use dry alcohol tablets instead of a candle or a light bulb, then we will get an additional advantage: alcohol combustion products have antiseptic properties.

Member of FORUMHOUSE topos proposes to involve the science of chemistry in the service of draining the cellar.

topos Member FORUMHOUSE

1 kg of dry calcium chloride takes 1.5 kg of water. Buy 50-100 kg. Downloading. A day later, you clean it, dry it (calcine it) and load it again. Merry work.

You can also use a good household dehumidifier (such as they drain pools), a heat gun. Or put an ordinary oil cellar in the center of the cellar - in this case, drying will be carried out due to thermal radiation. But this process is long and expensive (it may take several weeks of continuous operation of the device). Most importantly, without proper ventilation of the cellar, the desired effect with the help of a heater can hardly be achieved.

topos

To drive air with an electric heater is a stupid thing when the ground is wet, the air is moist and there is no ventilation. You will create a regular bath. You need exhaust ventilation with air intake near the basement floor.

For storage of supplies in the cellar, weak ventilation will be sufficient. Strong ventilation is more likely to hurt.

Jeeper FORUMHOUSE moderator-consultant

By strong ventilation, you disturb the climate in the cellar - for example, you can cool it down a lot in winter, and heat it up a lot in summer. This contributes to the formation of condensation and mold.

Nevertheless, competent, well-thought-out cellar ventilation is the key to successful storage of vegetables until the next season.

Tocon FORUMHOUSE member

The ventilation began to work, the cellar stopped crying (before that, one might say, it roared without ceasing).

Ventilation in cellars and cellars is arranged as follows:

An exhaust pipe is installed on the north side of the basement, which drops 10-15 cm relative to the ceiling.

A supply pipe is installed on the south side, which should drop to a level of 10-20 cm above the floor.

Usually pipes are installed diagonally, in opposite corners of the cellar. To avoid condensation in the cellar in the summer, the exhaust openings are closed for the warm season, and they also make sure that the lid is tightly closed and insulated as much as possible from heat (for this you can put a piece of foam on it). In autumn, when the temperature outside is lower than in the cellar, the cellar lid is opened and left open until the temperature is about +2 - +3 degrees. The warm, moist air of the cellar will be replaced by dry and cold air from the street, so during such ventilation, the damp cellar usually dries out quickly.

For the winter, with the exception of especially frosty days, only the inflow is closed.

Efh Member FORUMHOUSE

I can advise you to leave one hood open for the winter and insulate the pipe itself well (so that it doesn’t drag on with a jacket). No stitching, and nothing will freeze.

Some participants of our portal do not have ventilation in the cellar, but condensate does not form in it, since the causes of dampness were different - bad and cold walls and floors. Sometimes these shortcomings are easy to eliminate, and sometimes a global alteration of the cellar is required.

How to remove moisture in the cellar

Dampness is the first enemy for basements in country houses. The problem of dampness in the basement or cellar is quite common. There are many ways to deal with it, but it's even better to prevent it from happening.

Dampness in the cellar manifests itself in the form of condensate due to evaporation of moisture in the soil.

High humidity and dampness in the room contribute to the formation of mold and mildew, which can spoil the food stored there. The appearance of moist air occurs in a capillary way, that is, the smallest droplets of water penetrate into the earthen floor through the cracks, after which the moisture begins to evaporate, which provokes an increase in air humidity. It is worth noting that clay rocks raise water much faster than sandy rocks.

Before proceeding with the fight against, it is necessary to identify the cause of its formation. One of the problems may be the lack of insulation of the house, it is because of this that moisture will penetrate the walls of the house in cold weather, provoking the formation of mold. Most often, this phenomenon is characteristic of the upper corners on the walls, as moisture penetrates from above from the roof.

In addition, moisture enters the cellar through groundwater. Another reason for the formation of dampness is the lack of waterproofing under the floor covering.

Ways to deal with moisture

There are several options for dealing with moisture in the cellar of a country house, this is a method of concreting walls and floors, plus the use of roofing felt and liquid glass. It is worth paying attention to the use of an inexpensive way to eliminate moisture. It involves the use of plastic film, you can use already used. You will also need to use clay, a trowel, a shovel.

A good remedy for dampness is calcium chloride, which absorbs excess moisture. This powder is scattered in glass jars, which are placed in the corners of the cellar. For a small cellar, 500 g of powder will be enough.

In the case when dampness occurs due to groundwater that appears in the autumn and spring, additional waterproofing is required. To begin with, the floor is waterproofed by covering it with several layers of bitumen, which is then heated with a building hair dryer. On top of it, two layers of roofing material are laid, the height of which should be no less than 15 cm. The roofing material must be replaced with waterproofing, the advantages of which are the absence of decay and resistance to mold. The second stage of waterproofing involves the construction of additional walls and filling the space between the walls with waterproofing materials.

There should be a space of about 2 cm between the additional wall and the cellar wall. It is important to pay attention to the fact that there should be no mortar in this space. The thickness of the completed additional wall should be about half a brick.

First, brickwork is done, and when the mortar dries, the space must be filled with a special melted waterproofing material. Next, the cellar is covered with a white screed 10 cm wide.

What to do with dampness in the basement?

For many households, this is a frequent problem with the onset of the winter period. Due to the humidity in the room, mold forms, wooden shelves begin to rot and collapse under the weight of, for example, jars of pickles standing on them. In order to prevent such a situation, it is necessary to fight dampness and mold that have settled in the cellar or basement in time.

Basically, there are two reasons for high humidity - this is the close occurrence of groundwater and poor ventilation in the basement. The increase in groundwater is associated with the melting of snow, moisture seeps into the basement, where the walls get wet from the water. If there is poor ventilation in the basement or there is none at all, the air there becomes stale and there is no escape from dampness - condensation forms, moisture settles on the ceiling, walls and shelves in the cellar.

The consequences of dampness are quite sad - this is rotting, and the formation of mold, and the appearance of rust, as well as spoilage of products that were left in the cellar for storage.

If groundwater is the cause, a waterproofing device will be the solution to the problem, there is no other way to cope with it. First you need to equip the floor with waterproofing, which can be done in several ways. It is permissible to use small gravel, which is then covered with several layers of bitumen, on the heated layer of which a material for waterproofing (for example, roofing material) is laid. A concrete layer is organized on top (it is better to mix concrete with expanded clay).

It is possible to build a clay castle by covering and tamping a greasy layer of clay. Dry sand is poured on top and everything is poured with concrete or cement.

Both options involve raising the level of the floor. In cases where the basement already has low ceilings, this option is undesirable. That is why it is possible to deepen the floor to the resulting height of the waterproofing layer.

In addition to waterproofing, the method of erecting additional walls in the cellar is used. On the outside, the brick wall must be covered with a layer of waterproofing, although it is permissible to coat the wall with a layer of bitumen (the layer must be thick) or lay sheets of roofing material. The laying of the wall is carried out by the method on the edge. This method will undoubtedly reduce the usable space inside the basement, but it is a good way to get rid of damp walls. Therefore, you will have to sacrifice something, choosing between space or dampness.

Very often, dampness appears due to poor ventilation, when it is small, or simply clogged. A solution using exhaust vents with fans is suitable. Thus, air exchange can be increased, and moist air will not linger in the room.

Dampness in the basement is an unpleasant phenomenon. What to do if it appears? Before you begin to deal with the problem, you need to find out the cause of the appearance of moisture in the house. Understanding the cause will help you choose effective methods and for a long time, and maybe forever get rid of such a nuisance as wet surfaces in the room.

Why is dampness dangerous?

Why is it necessary to remove excess moisture from the premises? The appearance of moisture in the basement can lead to unpleasant phenomena that are difficult to get rid of.. Condensation on surfaces causes the following effects:

• the appearance of mold and fungus;
• violation of the temperature and humidity conditions of the premises;
• violation of the operating conditions of building structures, which leads to destruction in the foundation and other load-bearing elements;
• the appearance in the premises of various microorganisms that are dangerous to humans and lead to serious diseases;
• wetting of walls and ceilings, violation of interior decoration.

Causes of the problem

Mold in the basement appears as a result of dampness

There are several reasons why condensation may occur on the ceiling, floor and walls of the basement:

1. Basement ventilation problems. This can be caused by errors at the design or construction stage. Sometimes it happens that the ventilation ducts provided for by the norms are cut by incorrectly laid floor slabs or clogged with construction debris. The lack of normal ventilation leads to the fact that during cold weather, condensation forms in the basement, which is warm compared to the outside air, and the windows sweat.
2. Change in groundwater level. This problem is especially relevant in the spring, when the snow begins to melt actively, and the soil is oversaturated with moisture. The issue must be taken into account at the design stage and provide for a drainage system and reliable waterproofing of the basement. An increase in water in the soil leads to the fact that puddles appear on the floor. Their depth depends on the extent of the problem.
3. Why does such a phenomenon occur? The answer to the question will be - a violation of the foundation construction technology. If during construction attention is not paid to the vertical waterproofing of the basement walls, then during operation, moisture droplets will appear on them from the inside.

All these reasons why dampness appears in the basement are associated with the neglect of technology at the construction stage of the building.

Ways to fight

To understand what to do with dampness, it is necessary to correctly determine the reason why surfaces get wet. Further actions aimed at getting rid of excess moisture depend on its source. The cause can be determined by the location of the moisture.

• if droplets form on the ceiling and walls - the reason is insufficient ventilation;
• the formation of liquid drops only on the walls - the lack of vertical waterproofing of the basement walls;
• in the presence of puddles on the floor - the reason is flooding with groundwater.

Further steps are taken depending on the source of the problem.

Insufficient ventilation

If condensation has formed due to insufficient air exchange in the room, it can be removed by organizing additional ventilation. The same situation is relevant for the occurrence of dampness in the attic. This room also heats up, but at the same time it is in direct contact with the external environment.

Scheme of natural ventilation of the cellar

The contact of warm air with cold surfaces is the main and only reason why condensation forms. With sufficient air exchange in the basement or in the attic of the house, the air heated from the interior is cooled. Condensation does not form.

Ventilation in the basement of a private house or in the attic can be done in two ways:

• natural;
• forced.

Natural includes air and ventilation ducts. According to the norms, the total area of ​​​​the vents must be at least one four hundredth of the area of ​​\u200b\u200bthe room. Forced means the use of special equipment, the installation of which will require serious financial costs. The method is relevant only for large rooms.

To remove condensation on the ceiling and walls in the basement or in the attic, you must perform the following measures:

Scheme of forced ventilation in the cellar

1. Thermal insulation of engineering networks. In the basement there are water and sewer pipes, the temperature of the liquid in which is higher than in the room. This causes condensation to form on their surface. To get rid of heat losses, it is necessary to make reliable thermal insulation protection for pipes that sweat precisely because of heat leakage into a cold space. Thermal insulation measures can be performed using special materials. Manufacturers of mineral wool, polystyrene foam and extruded polystyrene foam produce special products that are convenient to put on pipes. Efficient materials allow you to remove heat leaks and get rid of the reason why the pipes sweat.
2. To eliminate dampness in the attic or in the basement of the house and the appearance of drops of moisture on the ceiling or walls, ventilation ducts or pipes are installed. After the construction of the house is completed, it is not possible to place ventilation ducts in the walls, so they are attached to vertical structures. To get rid of dampness on the ceiling and other surfaces, two pipes are provided in the room - supply and exhaust. They need to be done in different corners of the room, located at different heights from the floor.

After the reason why condensation appears in the attic or basement has been eliminated, the room is dehumidified.

Insufficient waterproofing

If the walls of the basement of the house (without a ceiling) are sweating, the reason is capillary moisture. You can get rid of it in one of the following ways:

1. Pasting waterproofing materials. They are presented on the construction market mainly by roofing material, linochrome and hydroisol. They are made on the basis of a canvas impregnated with bitumen. The gluing process is a rather labor-intensive undertaking. It is better to entrust such work to professionals.
2. You can protect the walls of the basement from moisture at home using bituminous mastic. In addition to it, polymer compositions and synthetic resins are used. The advantage of the method is the ability to do the work with your own hands. Minus - insufficient degree of protection. It is usually used together with pasting materials.
3. penetrating compounds. To get rid of capillary moisture, you can use compounds that penetrate concrete and increase its moisture resistance. The action is achieved by narrowing the pores in the structure. This method can be called highly effective, since not only the premises are protected, but also part of the supporting structure. The composition is able to penetrate to a greater thickness and prevent water damage to the foundation for many years.
4. Screens. This method is suitable for high pressure groundwater. Clay castle, geotextile or betonite become screens.

Work with any material is performed in the following sequence:

• removal of finishes from the walls, their cleaning;
• surface treatment with an antiseptic;
• primer;
• waterproofing walls and floors;
• finishing;
• a blind area around the perimeter of the building, if it is missing or damaged.
• draining the basement space.

Groundwater level rise

Wet walls due to high water levels in the soil is the most serious problem for a house presented. If the condensate does not require external measures, then in this case it is necessary to dig out the foundations. It is recommended to make waterproofing in the following order:

• excavation of the foundation;
• drainage device around the perimeter of the building;
• if necessary, strengthening the foundation;
• performance of external waterproofing (the same materials are used as in the previous case);
• performance of internal waterproofing;
• backfilling;
• blind area around the perimeter of the building;
• dehumidification of the room.

Scheme of the construction of the basement waterproofing structure at a high pressure of the groundwater level

The method will require impressive financial and labor costs, but it will protect the foundations and basement from groundwater. The material is selected depending on the pressure of the water. Several methods can be used together, for example, penetrating compounds along with pasting waterproofing.

When living in a private house, you may encounter dampness under the floor. This thing is unpleasant, harmful to health. With the prolonged existence of such a problem, fungus, mold, and other microorganisms cause diseases in those living in the house. There can be several reasons for dampness. Some are quite hard to believe due to their concealment under the finishing materials.

Causes of dampness

Dampness under the floor can appear immediately after the construction of the house or after many years of living in it. The main reasons leading to its appearance:

• Insufficient floor insulation
• Cracks in the foundation
• Poorly executed blind area around the outer perimeter of the house
• Lack of drainage
• Moisture in the basement
• Faults in floor construction
• Incorrectly installed home ventilation

In each individual case, it is necessary to carefully examine the structure of the floor, foundation, basement and determine the cause of dampness. Only after that you can start to eliminate it.

Lack of underground space ventilation

Some builders don't install underfloor vents. This becomes the reason for the appearance of dampness, mold, fungus in the warm season in the summer. During the heating season, these manifestations may disappear from the floor surface. But their destruction of the flooring will continue.

The elimination of this cause of dampness is carried out by the arrangement of products. In opposite walls, the area of ​​​​underground space, holes are made Ø 60-120 mm. It is better to arrange them diagonally from each other. To protect against rodents, the openings are covered with metal mesh. Ventilation options can be made in accordance with the figures below.

Insufficient floor insulation

Savings on materials, poor-quality insulation, improper design of the underground space lead to the appearance of dampness in it. And after a while, her unpleasant companions will appear on the surface of the floor inside the house. Having discovered this reason for the appearance of moisture, it will be necessary to additionally insulate the underground space. In this case, the dismantling of the finished floor surface is inevitable. Dampness will disappear only with properly performed insulation.

Incorrect blind area around the building

Failure to comply with the requirements for the implementation of the blind area, its absence, entails the penetration into the basement of precipitation, domestic water. Having established that this is the cause of dampness under the floor, the blind area is redone. The normative width must be at least 70 cm. It is taken into account that it must exceed the overhang of the eaves by 20 cm. Perform a blind area with a slope of 2-3 degrees from the house.

A properly executed blind area in accordance with the standard or economical option will prevent moisture from entering the basement and preserve the foundation.

Poor foundation waterproofing

In areas where there is a possibility of groundwater rising, it is possible to block their path to the basement or underground space with the right waterproofing equipment. Therefore, if it is not there, and soil moisture has begun to penetrate into the walls, the appearance of dampness under the floor is inevitable.

Having discovered this problem, waterproofing is created from scratch or supplements an existing one. To do this, a trench is dug around the house, the walls are cleaned, and vertical waterproofing is installed. It can be rolled or coated.

In the presence of a basement, it is necessary to pay attention to its humidity. The appearance of dampness, fungi, trace elements in it warns of the need to take action. Remember that concrete structures are also hygroscopic. And over time, the problem will move into the underground space. To eliminate in the basement, waterproofing the floor, ceiling, walls is carried out. If several causes are found, complex work is carried out to eliminate them.
