There are several causes for the appearance of moisture in the home, some can be avoided. For this reason, it is vitally important to determine the origin or types of humidity in homes, to resolve them in the best possible way.

In some cases, when due to construction defects or deterioration, the solutions can be complex and require work. I hope this is not your case.

Types of moisture in buildings

Condensation Humidity: One of the most common causes of moisture in a building is condensation. This is due to saturation of ambient humidity and is located mainly in bathrooms and kitchensbecause they are the spaces where the greatest amount of steam is produced. To prevent or resolve, we must resort to adequate ventilation of spaces.

We can also improve the thermal insulation of the house. This prevents the cabinets from maintaining temperature differences with the internal environment, avoiding condensation on them.

Capillarity humidity: these humidities are highly problematic, as they come from the ground and attack foundations and walls. The water rises due to the capillarity of the building materials (wood, mortar, concrete, ceramics, etc.). It can be recognized by the characteristic horizontal points. They originate from bad waterproofing.

Filtration humidity: originate from breaks in the supply pipes, drainage pipes or the presence of cracks in the outer walls. Moisture caused by damage to the pipes requires a timely repair of the rupture and the affected enclosure for the problem to disappear.

With cracks in the wrappers, it gets a little more complicated because moisture can go a long way away from its source, making it difficult to locate the problem. In addition, cracks can affect structural elements, making repairs difficult.

Unfortunately, I recently suffered from this type of humidity at home. The shower drain rubber broke and the water started to leak. Before long, the paint and small pieces of plaster on the ceiling of my bathroom and living room started to fall. To solve the problem, the neighbor’s shower was first repaired. As a lot of water leaked and much of the surface was affected, part of the roof had to be chipped. Leave it open for a few weeks until you are absolutely sure it is dry. And then fix it and finally paint it.

Environmental Humidity: these humidity are produced by the environmental situation of the construction. It affects the location of the building, the state of conservation. In order to avoid them, good ventilation, installation of thermal protection, among other measures to modify the microclimate of the area can be used.
