I’ve been dealing with some mould problems in my bathroom. I think this was due to no ventilation apart from a small window. There was also a hidden leak under the bath which has now been fixed. It doesn’t help that the previous owners used cheap paint, but I’m having the room repainted soon with proper stuff.
The outside wall has always had some mould patches, but it seems to have got worse since the fan was installed. I thought the fan was just pulling out all the moisture, so not necessarily a bad thing, but now I’m starting to worry it might be something else. Does anyone have any idea why this could be happening?
The fan is in the ceiling above the shower and goes through the loft, venting the air out through a small vent on the side of the house - photo attached. The electrician knows his stuff (been a sparky for over 20 years) so I have no reason to believe that it wasn’t installed correctly, but I’m confused as to why the mould situation has escalated. Any thoughts or advice please?
