What Causes Damp in Bedrooms?

One of the last things that anyone wants to find in their house is damp, as it can be difficult to get rid of and negatively impact your health.

Mold is unpleasant in itself if it is present in your home, but it can become quite aggressive and take over your walls.

If you are starting to notice any signs of mold, or you are worried that it may occur, then you might be wondering what causes it and how you can help prevent it from growing.

Thankfully, there are some things that you can do to avoid damp in your home when possible, and knowing the causes of mold growth can help you to do your best to stop it from happening.

What Causes Damp in Bedrooms?

There can be a few different causes of damp inside your home, and we are going to mention them below, so you can know what will increase the chances of mold developing.


One of the most common causes of damp in any home is condensation, but it mostly occurs in bedrooms, bathrooms, and kitchens.

This will happen when the moist air comes into contact with cold surfaces, which causes water to be deposited on the surface. This creates the ideal environment for mold to grow.

Too Much Moisture

Moisture can easily get into the air inside your home when you complete daily tasks, like cooking, cleaning, washing, and showering.

Moisture is something that often can’t be avoided, and through such activities, you can actually contribute to four pints of water in your home environment every day.

With modern advancements like double glazing and insulation, it can be really difficult for this mist air to exit your home, and this is when damp can occur.

Poor Heating

As well as cold air, warm air is another contributor to moisture. So, the temperature of the air inside your home and any impermeable surfaces will increase the amount of condensation inside your home.

If you live in a house that is under heated, you may experience higher levels of condensation. As well as this, dramatic increases in temperature can also increase condensation levels. This is why it is so important to consistently heat your home to increase the average surface temperature.

Poor Ventilation

If you do not have sufficient ventilation in your house, condensation and mold growth can occur more easily.

A good amount of air flow will allow warm air that contains moisture to escape from your home.

However, if there is insufficient air ventilation in your home, the warm air will deposit onto a cold surface, and lead to damp.

Does Putting the Heating On Help Damp?

Putting on the heating can work to prevent damp in certain circumstances. However, just because your house is warm, does not mean that you will not get damp.

Adequate ventilation is still really important if you want to avoid damp. Interestingly, there is one specific type of heating that will actively fight damp, which is infrared.

Many people have turned to using infrared panels to heat, and these panels work through the use of safe radiation. This means that they are able to heat the fabric of the building, and the people inside it, directly. The heat will be stored in thermal mass, even when you turn off the heaters.

Infrared heating can help to dry out the walls if they have previously been affected by damp, providing that there are no other underlying issues. They can work to ensure that the walls do not get cold enough for water to settle on them.

What Are the Signs of Damp in a House?

Some of the most common signs that you have damp in your home are:

  • A damp and musty smell
  • Physical mold on the walls, floors, or ceilings
  • Walls, floors or ceilings that feel cold or damp
  • Dark patches on the walls or plaster
  • Wallpaper that has started to peel back
  • High levels of condensation on your windows

Will a Dehumidifier Dry Out Damp Walls?

A dehumidifier will help to discourage the growth of mold and get rid of damp. A dehumidifier will work to remove the moisture from the air and collect the water when it has been condensed.

They will also then heat the air back up before they return it to the room. These units will run off electricity, and they can lower the levels of humidity in your home dramatically.

You will need to empty the water reservoir inside the machine quite frequently, depending on the type of dehumidifier that you buy and the amount of moisture that it collects.

They can also be plumbed so that they dispose of the water down the drain themselves, without you having to do anything. They are highly useful for getting rid of damp.
