Mould on external walls of first floor flat

Anonymous user 01/03/2024 - 2.52 PM

"I am moving into a new flat (for me) but built in around 1985. It is a first floor flat but on the walls in bedroom 1 and 2 is mould at floor level. It only appears on the external walls. Does this mean bad ventilation and is there an easy way of getting rid of it successfully. Is it treatable without putting air bricks through external wall which I dont think the Management Company would be too keen about."

Are you a tradesperson and able to answer this question?

sounds like condensation problem, increase ventilation by extract or window trickle vents, a piv would sort it out, the mould is aspergilus niger and will need aspecialist mould killer, bleach doesnt work as the spore formers survive
