Hi I will be embarking on tackling my small cellar next year. We have lived at the property for 4 yrs now and have come a long way in terms of reducing damp and humidity levels in the house (1750s coach house)
One remaining problem area is the cellar. It is damp down there. Signs of damp such as cardboard boxes soften fairly quickly and previous wood rot from many yrs ago. I plan to take the walls back to brick next Yr. Re point in lime and lime wash the compartment.
I do need some advice on ventilation though. I am aware this is key yo solving and damp/condensation issues as it is all about air changes over time.
My thoughts are to set up a negative pressure system using a tube fan and vent it directly to the outside atmosphere. My hope is this will create a negative pressure thus drawing dryer and fresher air from the house into the cellar. Also this will hopefully create a poultice for the cellar walls to draw out the moisture within and dry them.
The cellar is only small and will only be used for storage not a living space. Dimensions approx 5 x 2 metres. Any advice appreciated 🙏
