How to prevent dampness at home

Humidity in flats, premises and neighborhood communities is a more common problem than we think and can significantly affect the sale of a home. Therefore, whether you want to sell your house or if you are about to buy or rent one, it is important that you know how to detect if it has humidity or what type it is to find a quick and effective solution.

Do humidity problems affect the price of a house? 

When we look for a house, buyers always think that its value is lower than what they ask for; if we put ourselves on the opposite side, that is, as salespeople, the opposite happens, and we think that our home is “worth more”.

For this reason, before buying and selling a house it is important that a qualified professional carry out an appraisal of the property with Sky Marketing. An appraisal is simply a report that allows you to establish the value of a property based on its location, surface area, age, quality of materials or orientation.

Another aspect that is valued positively when it comes to appraising a house is its condition, which can increase or decrease its price by up to 25%. Hence, when looking for a second-hand home, buyers are especially attentive to the condition of windows, doors, floors, kitchen or bathroom, the elements that usually require renovations.

Humidity is no exception. In fact, avoiding humidity in a house is a challenge, since its presence or appearance can devalue the price of a home by up to 40% according to data from the Professional Association of Property Administrators of Madrid (CA Madrid). But what is the motive?

Fundamentally, the presence of humidity is related to poor ventilation and an unhealthy environment, harmful to our health due to the appearance of fungi, mold stains or mites.

In addition to affecting our health, not knowing how to fix the dampness of a house for sale is also related to poor insulation that can increase energy loss by up to 15%. And it is that humidity is closely linked with the energy certification of a home. For example, in flats or houses with problems due to water leaks, fixing the humidity at home is essential to obtain a good energy rating and maintain its price in the market.

Finally, humidity can considerably damage the structure of the building, the facades and even the facilities, hence the importance of taking measures as soon as possible. Only then can we keep the house in good condition for sale and that its value is not reduced.

Identify dampness to know how to avoid them 

Before explaining how to combat humidity at home, we will explain what types of humidity are the most common and how to identify them.

Humidity due to condensation

They are the most common and, although fixing this type of humidity at home is essential, its side effects are not excessively serious. The main cause of the appearance of humidity due to condensation is a loaded environment: when air with excess humidity comes into contact with cold surfaces (for example a wall, glass, the frame of a window, etc.) the steam condenses, going from gas to liquid and transforming into water. This type of humidity is related to insulation problems and is common in bathrooms and kitchens. In addition to problems in our day to day, condensation humidity causes corrosion of materials (for example the shower screen) and increases energy consumption.

Filtration moisture

This type of humidity is more serious and is produced by deficiencies in the insulation of the house or by the deterioration of its walls and walls. If when visiting a house, we see this type of humidity, we must seriously rethink your purchase. Possibly it is an old house, since the dampness by filtration appears over time, but it is also synonymous with poor waterproofing in newer floors or homes. In addition, to avoid this humidity it is necessary to invest more money, so it must be valued before formalizing the sale.

Capillarity moisture

The appearance of dampness by capillarity is conditioned by the terrain and by the construction materials. The usual thing is that these dampness appear in basements and garages, due to an excess of water in the groundwater table, and that they rise until they reach the walls and walls of the first floors and floors. This type of humidity is linked to the subsoil, and is often related to heavy rains and breakdowns due to water leaks. For this reason, before buying an apartment it is important to consult with the Community of Neighbors so as not to be surprised by costs of works or community spills.

How to combat dampness at home: practical advice 

Are you looking for the keys to avoid the appearance of dampness? Do you want an effective method to remove moisture in an old house? If so, these tips can help you.

Generally, the main problem with dampness is that it is not detected immediately, but it is necessary to see obvious signs that reveal its presence. Still, we can do some things to avoid dampness or, at least, detect it in its early stages and fix it as soon as possible. These small actions are:

  • Periodically check (annually or biannually) fissures or cracks in facades and walls that may represent a path of water seepage.
  • Check that the tiles are well positioned and that there are no breaks. Typically, when there are roof-related moisture problems, the first manifestation is small leaks. If we detect them, we must remedy to avoid problems in the future.
  • Clean drains, downspouts and / or gutters once a year.
  • Take care of possible cracks in windows or doors. It is also important to seal both elements, especially in areas with a high concentration of humidity such as the kitchen or bathroom.
  • Check for the presence of moisture. Rain leaks appear as patches, delimited, that increase with rainfall. Regarding outdoor humidity, its most obvious sign is the white efflorescence on the facade. You can check for condensation moisture by taping a piece of aluminum foil to the affected wall. If there is mist on the visible face of the aluminum, there are condensation problems.

Some simple tips to avoid dampness at home are:

  • Ventilate well. Good ventilation allows good air circulation and prevents humidity from stagnating.
  • Use exhaust fans. Especially when you cook or shower. Use the extractor hood in the kitchen, and if your bathroom doesn’t have a self-contained ventilation system, open the window a little after you shower.
  • Tends outside the home. Clothes that have just come out of the washing machine are loaded with moisture that is easily transferred to the environment.
  • Increase the temperature of cold walls. In this way, you will improve its insulating capacity and reduce humidity.
  • If you have to change your home doors, choose PVC ones, as they retain less moisture than aluminum ones.
  • Install double glazing on your windows. Possibly, this is one of the best investments you can make in your home, both to avoid humidity and to insulate the house and eliminate thermal bridges and energy losses.

The presence of humidity is perceived as an added expense and as an increase in energy bills. For this reason, and as experts in the real estate sector, at Tajarat properties we always recommend repairing dampness before putting a home for sale.
