Hi all
We have a single walled store room that is adjacent to our downstairs shower room - no DPC . I've noticed that a plasterboard wall in the store which is furthest away from the house is now showing signs of penetration damp and I've been advised that I need some ventilation in the store.
The vent from our shower is currently ducting into the store room but it's not venting out from the store room to the outside however. Hence I think this could be the main cause of the damp - i.e. moist air not escaping in these cold months. So thinking I may need to hire a circular core drill to cut out a 100mm hole for the extraction of the shower vent ...
However for general ventilation in the store, should I use the same core drill and create multiple 100mm holes and cover these with a square/round grill?
Or should I fashion my own air brick by simply drilling holes through the brick work at regular intervals using a bog standard large masonry bit - it's a single walled construction so should be a simple matter?
Finally, where should the air brick/vent be position for maximum effectiveness - high up near the ceiling or down near ground level.
Appreciate any advice here!
