Hi, wondering if anyone can advise me on this please? We have an old house and it's very cold and damp and mound grows in certain places. Our foundations are below the water table so when it rains it fills with water under the house, i think maybe that has a lot to do with the damp? However from what I've read i should hopefully be able to keep it at bay with correct heating and ventilation however I'm unsure when to heat/ventilate. Currently the heating is off all day until around 5pm-9pm. I open all the windows between 9am and 2pm. Does this sound about right? It is freezing in the morning but it seems counter productive and a waste of money to heat the house in the mornings only to let all the heat out the windows later on. However if I knew that doing this would help the damp problem then I wouldn't mind so much. Today I tried to do it the other way round and put the heating on as soon as we woke up until around 11am and also had the dehumidifier blowing (and karcher vacd all the windows as per usual). The house doesn't feel nearly as cold and damp now but when should i ventilate the house today? If I do it now I'll lose the heat! Or maybe I should do it in a couple of hours and then put the heating on for an hour or two after that?!
Any help much appreciated!
