Humidity at home, what do I do?

Have you removed a piece of furniture to clean and have you seen that you have a humidity that you did not know? The first thing we have to know is what type of humidity it is, since we will choose one solution or another depending on it.

There are several types of humidity: condensation, capillarity or filtration.

Only the humidity caused by condensation problems can be relatively solved on our part, just as we can avoid it by carrying out a series of guidelines.

However, the dampness of capillarity or filtration can hardly be solved with home remedies and will require the action of an expert.

Condensation humidity

It is the one that usually appears most commonly in homes and to a certain extent, we can avoid it.

This humidity is produced when the water vapor that is contained in the air turns into liquid when it comes into contact with a cold surface. In our houses it usually appears when the interior temperature of a house is higher than that of the exterior and it manifests itself mainly in the windows, walls and ceilings, either in the form of mist or water droplets (windows) or with black mold stains (walls and ceiling).

The main cause of condensation is a lack of ventilation in the home. Cooking, showering, turning the heat on too high, or drying clothes indoors can cause this type of humidity.

However, it can also come from a poor insulation in the walls For which there are solutions such as: applying a multilayer insulating coating (SATE system); insulation of the facade by chamber injection with polyurethane foam; or an exterior insulation of the facade with a metallic structure, among others.

There are some home remedies to remove stains moisture:

  • White vinegar: Mix it with water and apply it with a diffuser on the stain and let it act.
  • Sodium bicarbonate: it has antibacterial and antifungal properties and has a high absorption capacity. The trick is to rub baking soda on the affected area and let it work for a couple of hours. Then remove it with a brush.
Humidity at home, what do I do?


Remember to ventilate frequently, do not dry clothes on radiators, open the window after the shower, do not put the heating excessively high and cook with the extractor, among other measures.

In the case of areas with the possibility of the appearance of humidity due to condensation, leave a space between furniture and wall so that it transpires and passes the air easily without becoming condensed.

Also, you can put bowls with baking soda or salt in areas where dampness may appear, such as closets.

Filtration and capillarity

Regarding humidity by filtration, It is one of the most complicated to deal with and solve definitively, since they usually appear to be open cracks that will require an expert to close them correctly.

For their part, those of capillarity, are those that appear in the lower areas of the walls due to poor insulation in their foundations. The solution is to eliminate the direct contact of the wall with the ground and reassemble it on an elastic and breathable band.
