Moisture and mould

Moisture and mould in your home are two things you want to get rid of as soon as possible!

They are undesirable in your home and very unhealthy. Moisture and mould. If your home is too humid, you are at a greater risk of mould growth. It is important to take action quickly to avoid giving mould a chance. How do you go about doing that? How do moisture and mould problems arise? What can you do to prevent them? We are happy to tell you all about that!


Mould growth is always due to excessive humidity in the home. If you notice that the air inside feels stuffy or heavy, or if there is condensation on the windows, it is an indication that the inside air is too humid.

Everyone has daily moisture in their home; that is normal. Daily activities such as showering, cooking and washing, for example, all increase the humidity level. When the moisture cannot get out of the house, it becomes a problem. Too much moisture can cause mould, so it is important to properly ventilate your home. Ventilation changes the air in your home. Moisture can escape, and drier air comes in to replace it.

If you suffer from moisture and mould in your home, inadequate ventilation is often to blame. This is a problem you can often solve on your own. How? Read on for the tips we will provide later. If ventilating does not help, the problem may also be structural or related to the building systems, such as a leak or malfunctioning mechanical ventilation. It could also be a combination of both. In that case, ventilation alone is insufficient. If you suspect there is more going on which is causing mould to keep coming back, contact us and we will look for a solution together.


No matter the cause of mould, it is always important to address it thoroughly. Mould will not go away on its own; thorough cleaning is essential. Clean the area immediately when mould becomes visible. The longer you wait, the harder it is to get rid of it.

Mould removal does not involve complicated steps—hot water and baking soda works wonders. Wet the mould with the mixture and then remove it. You can also use a commercial mould remover available at various places. When removing mould, use gloves and a mask for your safety. In any case, never remove mould with a dry cloth or brush. First, because it doesn't work, and second, because by doing so, you spread the mould into the air and then breathe it in. This is bad for your health and can cause shortness of breath, coughing and allergic reactions.


A proper balance of moisture, heat and ventilation is key to preventing moisture and mould problems. Overly economical heating and insufficient ventilation are bad ideas in any case. You can read our recommendations below.


  • Proper ventilation allows moist air to escape and drier outside air to replace it. This keeps excessive moisture from lingering in the house.

  • Did you know that a dry house heats up faster? It's better for your health, too. Always keep ventilation grilles open—yes, even in winter.

  • Keep the grilles clean.

  • If there are no vents in your home, open a window regularly.

  • If you have mechanical ventilation, never set it lower than 2, and set it to 3 while cooking or showering.


  • Never let your home drop below 15 degrees. Moisture cannot escape properly in an excessively cold house. This also applies at night and when you are not at home.

  • Check the table below for the minimum and desired temperature for each room in the house.


  • Keep the bathroom door closed when showering or taking a bath.

  • Set the mechanical ventilation to the highest setting while showering. After showering, leave it on for at least 20 minutes.

  • After showering or bathing, dry the walls and floor with a squeegee to remove most of the moisture.

  • After showering or bathing, keep the bathroom door closed for 15 minutes, then open the bathroom window or door.


  • When cooking, always turn on the cooker hood and/or open a window.

  • Cook with the lid on the pans as much as possible to minimise the amount of water vapour released. This also saves energy and, by extension, money, because the contents heat up faster.

  • Set the mechanical ventilation to the highest setting while cooking.


  • Hang laundry outside as much as possible if you have the option. Open a window if you hang laundry inside. Two open windows across from each other is even better, as moisture can get out more easily.

  • Do not hang overly wet laundry indoors; run it through a spin cycle first. Most washing machines have a programme for this.


If you have tried everything and these tips do not help keep moisture and mould out of your home, there may be more going on. Contact us, and we will investigate how we can help you combat moisture and mould.
