My mum has mould that appears on the floor and around the skirtings in two corners of her bedroom, it's the ground floor of a block of flats built around 1930s. There is a DPM and DPC course, no problems have occured before, she'd been living there for decades. Have a look at the pictures.
Before I get my moisture meter on it, has anyone any guesses? Leaving aside rising damp/penetrating damp possibilities for now, as there are are signs of this anywhere else... could this possible be related to her having loads of old books + lack of ventilation. I've told her to make sure the trickle vents are cleaned and unblocked, but it's strange this is suddenly occuring.
