What is Damp?

Body

Damp refers to the presence of excess moisture in a room. In addition to making your home feel cold and uncomfortable, it can be a serious problem as it can cause structural damage to your home if it’s not dealt with. The four most common types of damp include rising damp, penetrating damp, damp caused by defective plumbing and damp caused by condensation

What is Mould?

Body

Mould is a type of fungi caused by excess moisture. It often forms in cooler points, such as windows, in the corners and edges of rooms, and behind and inside wardrobes and cupboards (especially if they are against an external wall). It can even grow in other places and on surfaces and items where air is unable to circulate.

What is Condensation?

Body

There is always some moisture in the air, even if you can't see it. Condensation happens when moisture in the air meets a cold surface like a window or wall. You may notice it when you cook, shower or dry clothes indoors - think of a mirror steaming up when you're taking a bath - that's condensation. 

If surfaces are left wet, a build-up of condensation can occur which can lead to problems with mould. This can have a knock-on effect on not only the condition of your home, but your health too. 

What causes damp, mould and condensation?

There are 5 key contributors to excess moisture in your home: 

  • Heating water 
  • Leaks 
  • Cooking 
  • Bathing/showering 
  • Drying clothes indoors 

Too much moisture can cause condensation and mould in your property. 

There are some simple steps that can be taken to help reduce the effects of these on your home, such as wiping down the windows and sills each morning. Read on for more help and advice.

Bathing and showering

There are a number of ways that you can deal with bathroom condensation to help keep the space drier and less prone to mould growth. 

Running water in baths or showers causes clouds of moisture. If you can, try turning down the temperature of your bath or shower. By lowering the temperature of the water, your bathroom won't get as hot and its air won't hold as much moisture, which will help to reduce condensation. 

Other ways to reduce moisture include: 

  • Wiping down surfaces after a bath or shower.

  • Opening a window is one of the simplest ways to reduce condensation in the bathroom, it helps excess moisture and steam escape rather than clinging to the water vapour and landing on surfaces around the room. 

  • Closing the door as well as opening a window will help make sure moisture doesn't escape into other areas of your home.

  • An extractor fan can help remove steam and moisture from your bathroom and vent it outdoors.

Cooking

Kitchens are one of the biggest sources of condensation in the home. The combination of different activities such as boiling a kettle or cooking on a hob, contribute to the release of moisture that can build up in the air and result in water droplets forming on windows and soaking into surfaces to form damp patches. 

Minimising moisture will help to reduce condensation so: 

  • Keeping pan lids on when cooking will reduce the moisture that is released into the cooler air 

  • Extractor fans are a great way to reduce moisture in a kitchen, removing steam and stopping it spreading to other parts of the home.

  • Closing the kitchen door and opening a window will prevent steam escaping into other rooms.

Drying clothes

If outdoor space is limited or the weather isn't warm enough to dry your clothes outdoors, there are some practical steps that can help reduce excess moisture when drying clothes indoors.

  • An extra spin cycle can help to remove any excess moisture.

  • Using hangers on an airer can help air circulate. 

  • Drying clothes in the bathroom with the window open and the extractor fan on will reduce the moisture that is released into the cooler air 

  • An over the bath airer in the bathroom can be a great option.

Heating water

Water heaters in small, closed-off rooms have a greater chance of showing condensation than those in large, airy rooms. Opening a window will help the air around a water heater to circulate and prevent condensation. If that's not an option, use a small fan to blow air around the water heater to circulate the air.
