Hi, I just thought I would post some information regarding the damp problems some people have been experiencing in their homes. I seem recently to have had more and more calls from people who have either “had somebody in” to fix their damp problem which has not worked or from people who have damp in their property who just want it sorted out. Most problems with damp in modern properties in Spain are not caused by water ingress or water penetration. In some cases, there have been issues with leaking pipework on central heating systems or badly sealed patios, doors or windows which I have successfully sorted out, but in the main the problems stem from condensation and lack of ventilation. The average person gives out 1.5 to 2.5 litres of moisture per 24 hour period via breathing and other bodily functions which are best left to the imagination. Add to that boiling kettles, cooking, washing etc. and you have a lot of water vapour released into a property in a day. All of that moisture has got to go somewhere and with windows shut and no natural ventilation it stays in the property and causes damp and consequently mould. The answer is really quite simple. Keep at least one window slightly open or alternatively fit natural draught ventilators. I have fitted so many over the 8 years I have been working in Spain that I have lost count. It is not an expensive fix but they do need to be done properly and you need the correct ones fitted. I am a HVAC engineer, not a builder who remedies the symptoms and does not cure the cause. If you need more detailed free advice I can be contacted via this forum or you can find my details on the Polaris world forum, just put in a search for air conditioning and I'm sure I will come up.
