A quick guide to condensation

Whether you reside in a historic building or a modern new build apartment, dealing with condensation can be a frustrating challenge. While the initial effects may seem minor, if left unchecked, condensation can lead to more severe problems that could damage your property and pose health risks.

This article outlines the causes of condensation, how to prevent it and tips to keep mould and dampness at bay.

What Is Condensation?

Condensation occurs when warm air meets cold surfaces or when there’s an excess of humidity inside a property. This is particularly common during winter, as central heating is often used during the cooler mornings and evenings, creating the warm air which inevitably meets a cold surface in the property.

In addition to heating, daily activities like cooking, showering and drying of clothes, all release warm moisture into the air. When this moist warm air encounters a cold surface, it cools rapidly, causing water droplets to form.

Condensation is generally less of an issue in the summer, but during the colder months, the humidity levels inside homes tend to rise due to increased heating and residents keeping the windows closed. As outside temperatures drop, condensation becomes more prevalent, often appearing on windows and external walls.

While a bit of moisture may seem harmless, untreated condensation over time can lead to the growth of black mould on walls, ceilings, and around windows. This mould is not only unsightly but can also cause health issues such as sinus problems, skin irritations, and even bronchitis.

If you notice black mould around your windows, such as in room corners, on walls and ceilings, behind furniture, or inside cupboards… you may have a condensation problem.

How to Manage Condensation

The first step in managing condensation is to control its presence in your property. For instance to remove water droplets, use a sponge to remove water droplets from windows, mirrors, and glass shower doors. Follow this up with a soft towel to wipe down any remaining moisture on walls and other surfaces.

Once the property is dry, consider these strategies to prevent condensation from returning:

  • Use Dehumidifier: Invest in a dehumidifier to reduce indoor humidity levels. These devices draw in air, remove moisture, and help keep surfaces dry. Place dehumidifiers in rooms where condensation is most common, such as the kitchen and bathroom. You may also want to use one in a bedroom on cold nights to prevent moisture from your breath from condensing on windows and walls.
  • Reduce Moisture Without Extra Cost: Simple habits can help reduce moisture. When cooking, keep lids on pots to minimise steam, and always use the kitchen mechanical extractor fan. If the kitchen or bathroom lacks effective ventilation, try keeping a window open during activities like cooking, using the tumble dryer, or showering. It’s important to keep doors closed when using these rooms to prevent humid air from spreading throughout the property.
  • Evenly Heat The Property: Prevent condensation from forming on cold surfaces by maintaining even heating throughout the property. Set a thermostat to the same temperature in every room. If you have a room that is rarely used, keep the door closed and try to open the windows for a couple of hours each day to reduce the risk of condensation and dampness.
  • Allow Airflow in the Bedroom: If condensation is an issue in a bedroom, consider moving furniture slightly away from the walls to promote airflow and minimise clutter where possible.

Long-Term Solutions for Condensation

Preventing condensation is easier than addressing its consequences. For long-term prevention, consider investing in proper ventilation and insulation.

Effective ventilation is crucial for managing condensation. Since keeping windows open during winter is impractical, it’s advisable to install extractor fans in your bathroom and kitchen if they aren’t already in place. A small fan installed on an external wall can also help when performing tasks like washing up or boiling the kettle. Run the bathroom extractor fan during baths or showers and keep it on afterwards until the room is clear of steam, ensuring the door remains shut.

Responsibilities for Damp, Mould, and Condensation in Leasehold Flats

Addressing issues like penetrating damp or external water leaks typically falls under the responsibility of your freeholder or management company. However, it’s always best to check your lease to be certain of the responsibilities – certain parts of a property will fall under different responsibilities such as the windows.

Condensation, on the other hand, is generally the leaseholder’s responsibility, as it is usually caused by daily living activities within the property.

It’s important to recognise condensation early, and not confuse it with water ingress from outside and ultimately take prompt action to prevent it from becoming an issue or worsening. Quick routine cleaning on a frequent basis of “hot spot” areas, such as those mentioned above, should ensure this issue never has chance to arise.
