What is Condensation?

What is Condensation?

Condensation is a very common problem in UK households. For most properties, it can be a seasonal problem that is very controllable with sufficient heating and ventilation. However, for a large number of properties, condensation can be a significant problem. If left untreated, condensation can lead to black mould growth and cause wooden frames to rot.

What causes Condensation?

Condensation is caused when warm air in the atmosphere comes into contact with a surface such as a window or a wall that is colder. The warm air can’t hold the moisture so is released onto the cold surface in the form of water droplets. When the room temperature remains warm for a considerable amount of time, and the condensation is not dealt with, it is then that mould starts to grow. Condensation in a property can be a sign of poor heating and poor ventilation.

Early signs of Condensation

The early signs of condensation in a property can be pretty easy to spot. The sooner you spot the signs of condensation, the sooner you can effectively deal with the cause to prevent further problems.

  • Water collecting. The most common early sign of condensation in your property will be water collecting in droplets and fog on your windows and window frames.
  • Damp and wet walls. Condensation can also show itself on walls, making them wet to touch and the presence of damp patches.
  • Peeling of wallpaper, paint or plaster. Where there is condensation on the walls, it will most likely cause the wallpaper, paint, or plaster to bubble, peel and flake.
  • Mould growth on walls, clothes, and furniture. Fabric, furniture, and furnishings that exposed to condensation will show patches of mould growth, often black, green and white in colour.
  • Musty smell. Another common early sign of condensation is a heavy musty smell in the property. This is due to the high humidity in the air and mould growth. This smell will not be masked by air fresheners or odour removers.

Treating Condensation

As with all problems stemming from excess moisture, the first step is to find and tackle the source. This prevents any further damage from occurring such as black mould and peeling walls. Tackling the source of excess moisture can be as simple as opening windows throughout the day, turning on the extractor fans whilst cooking, and drying clothes outside. More serious condensation issues require professional mechanical treatments. When the condensation has been treated effectively, the only thing required to do after is clean away the black mould with specialist remover.

Health risks of Condensation

Condensation from excess moisture promotes mould growth. The mould is caused by a fungus that releases spores in the air. The spores can trigger respiratory problems in children, the elderly, or those with pre-existing health problems.
