Condensation FAQ

Condensation and mould control FAQs

Many properties, especially tenanted flats can suffer from condensation, resulting in black or green mould growth developing on furnishings, clothing and the walls/ ceilings within the property. Based in Witney, our services are available throughout Oxfordshire and surrounding regions.

Why does this happen?

Condensation occurs when the water content of air rises above a level called the ‘dew point’. At such time, water droplets will form on the coldest surfaces e.g. windows, external walls etc. 

On average, a family of four people will produce about two gallons of water vapour per day from activities such as cooking, bathing, breathing and the washing and drying of clothes. 

It is also a fact that nowadays most properties are insulated to prevent warm air from escaping. This reduction in ventilation allows the air contained within the property to reach a higher relative humidity. 

We recommend envirovent ventilation units, ranging from Extractor Fans utilising humidistats to PIV Units. More information on these can be found on their website.

If you would like one of our surveyors to complete an inspection & provide a report & advice regarding condensation, this can be arranged. Please note, these visits are chargeable. Please contact our office for more information.

Tips to help prevent condensation

Though we do recommend the installation of PIV Units & extractor fans with humidistats to control condensation, we always offer the below advice to our customers prior to the installation - potentially you could control condensation and eradicate mould without spending any money.

The key to eliminating condensation is to change the way you live in your property. The most important change is to increase the air circulation to minimise the amount of moisture and to ensure the property is heated adequately.

Try following the condensation control steps below. If you need any advice, please don't hesitate to call our office. Sometimes the below steps do not solve the issue - if that is the case it is worthwhile organising for one of our surveyors to complete a chargeable inspection on the property.

  • Keep your property well ventilated - open windows as regularly as possible to allow moist air to escape.
  • As it is cold air that causes warm air to release moisture, try to keep heating levels within your property at a constant temperature, especially in the winter.
  • If drying clothes, do it outside. If this is not at all possible, put them in a closed room with plenty of ventilation and keep the window open. If using a tumble dryer, make sure the vent pipe runs outside your property or out of a window
  • If cooking or showering, keep the door closed, use extractor fans and open the window when you can.
  • Check to make sure airways within your property are not blocked, such as air bricks or chimneys.
