How to avoid condensation at home

In winter, with the heating working and the ventilation of the house restricted by the cold, it is common for condensation to appear in homes, so we bring you these tips to avoid it.

Condensation appears when water vapor becomes liquid due to cooling , for this reason our homes are more exposed to it during winter, when the use of heating and lack of ventilation are more frequent.

Although these are not the only reasons for its appearance. Routine practices such as cooking, showering, drying clothes or ironing during winter are also reasons why humidity can occur due to condensation , and this, like any type of humidity, is harmful to both the home and our health.

Mold stains on walls and other surfaces, the deterioration of furniture or the persistent smell of humidity in the environment are problems derived from condensation , as well as allergies, respiratory problems, lung problems, rheumatism, asthma, bronchitis or headaches, so it is important to solve it.

Insulating materials

The most obvious solution is to have good insulating materials in the home. Glass itself does not act as an insulator, so windows are the biggest source of condensation in homes. Currently, however, there are windows with double glazing or hermetic double glazing, which significantly improve thermal insulation.


In winter, homes are less ventilated due to the cold outside and the desire to save the heat produced by the heating, but ventilation is very important to avoid humidity problems.

Above all, when carrying out those actions that produce more steam, such as showering or cooking, it is important to open the window when finished to prevent the steam from condensing on the walls of the house.


Humidifiers are devices that keep the humidity of the environment constant in a closed space , so they can be very useful in spaces that cannot be ventilated properly.

Daily tricks

There are also tricks that can help us in our fight against condensation. These are simple steps that may not seem important, but they will greatly reduce the steam that forms inside your home.

  • Shorter showers. Much of the condensation that forms at bath time can be avoided with shorter showers and warmer water.
  • Cover cooking containers. In addition to saving time and energy, covering the containers will prevent humidity problems from multiplying.
  • Close the doors and open the windows. The steam that forms in the bathroom or kitchen passes to the rest of the house when we open the doors, so it is important to close these doors and open their respective windows to ventilate these spaces.
