One of the biggest problems we see on property inspections is keeping damp out of your home caused by condensation. If not treated correctly damp could cause real damage to the property and even your health so it is best avoided.

Symptoms of condensation and damp;

  • Water droplets on windows or walls.
  • The appearance of dark mould, particularly on glass or around windows
  • An unpleasant mouldy smell.

Dampness in properties is usually caused by excess moisture building up in the room and having nowhere to go unless property ventilated. Damp can be caused by a number of things from breathing & cooking to showers & bath. The biggest culprits of this damp issue are usually small houses, flats or properties with no outdoor space but larger houses with big gardens are by no means immune to the problems. We notice a large upturn in damp here in the UK through the colder months when its harder to dry clothes outside and to cold to have a window open leaving all the moisture trapped inside.

This chart courtesy of gives an incite in to how much moisture can be produced in your home in just one day and you may be surprised by the results.

Washing clothes 1 pint
Bath and personal washing 2 pints
Two people active for 16 hours 3 pints
Cooking and boiling a kettle 6 pints
Using an un-vented tumble dryer 6lb load 9 pints
Total moisture produced 21 pints


Our check sheet on how to keep damp out of your home and what to do if you get damp.

  • In the morning have a leather shammie to wipe away condensation from the window. Once up close the door and slightly open a window. Just your breathing through the night can over time cause enough water build up to cause damp. If its warm enough sleep with a window open to get air flow through the room. Another more expensive option is to invest in a dehumidifier.
  • If you have a bed, wardrobe or chest of draws that are in a corners we suggest moving them slightly away from the wall to allow for air low. We see the worst cases of damp around beds that have been crammed in to a corners. So, wherever possible, try to avoid putting a bed in the corner of a room.
  • Turn the extractor fan on when cooking and taking a bath or shower. All that steam has to go somewhere and it needs to be outside. If your property doesn’t have these then we suggest opening a window slightly when cooking and opening a window after you have showered with the door firmly closed.
  • Don’t dry clothes in the house unless you have to. If you have to then put them in the bathroom with the door shut and extractor fan on or window open.

If you notice mould on your walls you need to clean it off quickly and properly. Start by cleaning off the mould with spray containing bleach. This will help remove the staining that mould can leave behind. Leave this to dry overnight and then treat the affected area with an anti-fungal wash and leave that to dry. Always follow the manufacturer’s guidelines and consider wearing a face protection when using.
