The symptoms of condensation can cause panic. When water appears on walls and ceilings it can be quite alarming… its must be damp! But not necessarily. So please, check with a Chartered Building Surveyor before you go ahead with a costly damp course.
We often get enquiries from worried house owners who cannot control what seems to be damp. So, we hope this article provides some reassurance that condensation is usually a case of poor ventilation rather than anything sinister, such as rising damp!
Drying laundry inside the house, cooking and steam from the bathroom, etc. will create condensation and if the home doesn’t have adequate ventilation, water in the air gets trapped in the room and with no means of escape it will then be found running down the windows, walls and even dripping from the ceiling.
From the daily routine of showers/baths, boiling kettles, cooking, using a tumble dryer, air drying clothes, breathing and sleeping, a family of 4 will contribute approximately 4 pints of water per person, per day. This is equal to over 100 pints of water vapour a week, which has to go somewhere. Imagine 100 pints of your favourite tipple all lined up each week, that’s a lot of water.
Condensation occurs when warm air collides with cold surfaces, or when there's too much humidity in your home. When this moisture-packed warm air comes into contact with a colder surface, it cools down quickly and releases the water, which turns into liquid droplets on the cold surface.
If left to continue mould appears which is both unsightly and can be bad for health. Plus, it can rot wooden items in the property such as; window frames, floors, furniture and plaster.
Older properties were designed to breathe - given air bricks and fireplaces to draw air through the property taking the moisture out.
We have inspected many properties to find the air bricks are blocked - usually this has been done on purpose to prevent drafts. However, it is precisely these drafts which ventilate the room to prevent damp in the air. Also, fireplaces which have been closed up or blocked can reduce the vital air flow.
Usually there are simple remedies which can return the airflow in the property, ensuring air bricks are blockage free. Also check the washing machine is vented to the outside, clothes are dried outside as often as possible, close the kitchen and bathrooms doors, open windows while cooking and using the shower and cover pans whilst cooking.
Do not let a room get very cold for long periods. Check unused rooms frequently for condensation and keep them heated a little (and ventilated) as even relatively dry air will cause condensation if it is cooled enough.
Remember a ventilated home is much healthier environment to live in too!
