Humidity is among the most common reasons accelerating the deterioration of a dwelling. It clearly manifests itself in many different circumstances.

The appearance of saltpeter at the bottom of walls, the development of mold and fungi on the ceiling or walls, water leaks—many incidents are caused by this scourge.

In any case, it is entirely possible to get rid of it once and for all. To achieve this, you must first locate the source of the problem.

How to know where the humidity comes from?

Many people tend to neglect it. However, this phenomenon can be costly to repair. During a construction project, some people choose porous materials that are sometimes inexpensive. However, they are the cause of the problem.

In case of an house extension: what are my legal obligations? This question concerns most people. But they overlook humidity. However, the latter prevents the project from being completed because it weakens the foundation.

To avoid wasting money, try to identify its exact origin. If the issue comes from outside, it usually attacks the facade. Most of the time, its main causes relate to waterproofing defects. Otherwise, the exterior walls are covered with a non-breathable product.

If humidity only concerns the inside of the house, it sometimes comes from poor ventilation. Aside from that, infiltration and water damage are among its common causes.

In any case, it is safer to consult a professional to find the most suitable solution to the problem.

How to know what the correct humidity level is?

When the humidity level is too low or too high, it causes quite a bit of damage in the home. Mold appears and then develops. The condensation problem manifests. Wall coverings peel off. Bad odors invade the house. These are just a few examples among many others.

Aspect	Description
Definition of humidity level	The humidity level represents the amount of water present in the air, expressed as a percentage (%).
Ideal indoor humidity level	It is generally between 40% and 60% to ensure optimal comfort and avoid problems related to humidity or overly dry air.
Measuring humidity level	Use a hygrometer, a simple-to-use device that measures ambient humidity in real time.
Consequences of too high humidity	A humidity level above 60% can promote mold formation, dust mite proliferation, and damage to the building.
Consequences of too low humidity	A level below 40% can cause dry skin, respiratory irritations, and damage wooden furniture.
How to adjust humidity level	To increase humidity, use a humidifier or place plants. To decrease it, prioritize good ventilation and a dehumidifier if necessary.

Excessive humidity also has repercussions on the health of the occupants. It causes several illnesses such as allergies, eye irritations, asthma, respiratory disorders, headaches, nasal congestion, and increased fatigue.

To avoid reaching this point, it remains important to know the correct humidity level in the house. According to experts, the ideal is between 45 and 60 %. It is strongly recommended to get yourself a hygrometer or humidity tester.

Unlike the gas chainsaw, woodworking machine or Japanese saw, this device is not dangerous at all.

Since it is very easy to use, it is intended for everyone. Thanks to this instrument, you can measure the humidity level in the air at any time.

Can the source of the problem be treated permanently?

Of course, there are countless solutions to permanently get rid of it. To avoid making a mistake, there is nothing better than consulting a humidity professional.

With their knowledge and experience, they will be able to detect the origin of the problem to find the best solution.

If the issue is due to poor ventilation, it is advisable to revise the system. With technological advances, many innovative devices have been discovered that improve ventilation in a home.

In case of water leaks, calling a plumber is an urgent solution. This technician will be able to repair the problem quickly.

The bathroom is one of the places most affected by the humidity problem. The use of a dehumidifier is strongly recommended. The same applies to other damp rooms such as the kitchen and the cellar.

When rainwater stagnates and makes the exterior walls damp, specialists recommend draining the land.

As for rising damp, it can be permanently eliminated with resin injection into the interior walls. And when humidity attacks the basement or cellar, tank lining presents a permanent and effective solution.

How to remove humidity in a house naturally?

• Regularly air out the house: The simplest tip to implement is to sufficiently air out the home. To do this, you just have to open all the windows for 10 to 15 minutes a day, preferably in the morning. Thanks to this habit, you manage to limit the proliferation of fungi and bacteria caused by humidity.
• Avoid drying laundry indoors: Besides that, avoid drying your clothes in living areas. Otherwise, the water contained in the laundry only increases the humidity level in the air. It is better to hang your wet clothes outside. If you live in an apartment, using a tumble dryer solves the problem.
• Install an extractor hood in the kitchen: In the kitchen, it is inevitable to produce steam due to cooking food. However, this situation also promotes humidity. Fortunately, you can limit it by installing an extractor hood.
• Use indoor plants: There are also several grandmother’s tips that have proven effective so far. Using indoor plants is one of them. Some plants are moisture-loving.
• Use natural moisture absorbers: Salt is also a moisture absorber. The same goes for newspaper and charcoal. With these different options, you can apply the one that suits you best.

How to fight against humidity and mold?

The appearance of mold is one of the signs indicating excess humidity in the house. This microscopic fungus proliferates more quickly in a humid environment. Since it releases allergens, its presence can cause countless skin and respiratory allergies.

To avoid contracting them, it is necessary to eliminate them completely. Do not hesitate to clean the contaminated walls with bleach.

Alternatively, it is possible to use paint or anti-humidity coatings that protect the walls. It should be noted that this treatment is a superficial solution. It is therefore not sufficient depending on the severity of the situation. It is better to focus on the cause of the humidity.

If it comes, for example, from the porosity of the walls, technicians often suggest waterproofing treatment to make them impermeable.
