Thanks for these videos. You've helped me solve (I think) an issue where I was getting 'rising damp' on an internal wall but I think it's due to condensation above the dpc and localised to that wall either due to a high density of pipes or possibly the plaster going too low. Was a mystery to many people I've got in for advice. Root cause = poor drainage at front of house.
Thanks for sharing! 🙌 That’s a great example of how condensation and poor drainage can mimic rising damp. I love a good damp detective story - tell everyone! 🕵️♂️💧 Ironically, the PCA (formerly part of the BWPDA) once recognised high sub-floor humidity and condensation above the DPC as common causes of internal damp, far more than rising damp. But that knowledge has quietly disappeared from their literature. 🤔📚 If you want to know more about the real causes of damp, check out damp.ai for evidence-based advice! 🔗🧠
I am learning a lot from your videos. I currently have a dehumidifier running in our kithcen, as my wife likes to use a traditional airing rack at ceiling height to dry clothes. It seems to be keeping a reading of between 45% and 55%. Is this a good figure to aim for? Thanks.
Glad you're finding the videos helpful! 😊 Typically, a relative humidity reading between 45%-55% is fine for a kitchen. However, humidity is relative to temperature, and what’s more important is the amount of vapour in the air, expressed as the dew point (°C). The dew point should be kept below the outside temperature through targeted ventilation and dehumidification. Check out Dew’s Law here: damp.ai/dews-law If your hygrometer doesn’t display the dew point, you can use this tool: mouldpoint.co.uk Drying clothes indoors without a dehumidifier is rarely good practice. For instance, when drying clothes on an Aga, we always run a 20-litre dehumidifier until the dew point drops below the outside temperature.
