Water drops on glass

How to keep condensation at bay this winter

You may have noticed more condensation on your windows during the winter months, so in this simple blog post we have explained the causes of condensation, along with its effects and preventative measures.

What is condensation?

Condensation is a result of airborne water vapour condensing into a liquid, which is deposited on interior – or exterior – surfaces.

What causes condensation?

Condensation is a result of warm air colliding with cold surfaces, or when there is an excess amount of humidity in your home. Condensation is more common during the colder winter months, when your heating is used more frequently on cold winter mornings and evenings.

What can happen if I don’t prevent condensation?

If you don’t regularly remove condensation, or follow ways to reduce it, a build up can lead to greater problems. Condensation can lead to mould build up around the edges and sills of your windows, and this could eventually damage your walls and furniture.

How can I minimise condensation in my home?

If the biggest cause of condensation is the variation of inside room temperature, this can be controlled by replacing single glazing with energy efficient double or triple glazing, which works to maintain a higher surface temperature of the interior facing glass.

If this isn’t an option – or exterior temperature changes are extreme – condensation and its long term effects can be kept under control through regular removal of the excess water, using a dry cloth to wipe down the surface. Other preventative measures include:

  1. Correct air vents: If you have a washing machine or dryer in your home, ensure that this is correctly vented. Litres of water can be emitted into the air from a single wash, so adequate ventilation is essential to minimise condensation.
  2. Bathroom tip:  When showering or bathing, turn on your extractor fan to eliminate steam and moisture that results from running warm water in a cold environment.
  3. Drying clothes: As drying clothes in the winter isn’t always possible outside, keep wet washed clothes in a bathroom with the adjoining door closed and, ideally, with a window open.
  4. Furniture care: To allow air to circulate fully around the house, when possible, make sure that your furniture is at least 50mm away from walls.

Following these tips should help reduce condensation in your home.
