My landlord has booked a painter for recurring mould. What should I ask him to investigate?
Housing"Painter booked for Friday," my landlord texted. I replied, "Will anyone check why it keeps coming back?" He sent a thumbs-up, which could mean either question had been answered.
I'm renting privately in England. A patch behind the bedroom wardrobe was cleaned and painted two months ago. It has returned, and I've photographed it before moving the wardrobe away. Both times I noticed it after several wet days, but I don't know whether that points to a leak, condensation or something else. The landlord says he'll lend me a dehumidifier and wants the room looking decent quickly. That is more help than doing nothing; it still leaves me wondering what the painter has been asked to do.
The [government's damp and mould guidance for England](https://www.gov.uk/government/publications/damp-and-mould-understanding-and-addressing-the-health-risks-for-rented-housing-providers/understanding-and-addressing-the-health-risks-of-damp-and-mould-in-the-home--2) says the underlying cause needs addressing alongside removal. I don't want to diagnose the wall myself or leave the mould there while we argue.
Friday is my only day off this week, and I can be home from two. How do I accept prompt help while getting a clear investigation plan, rather than another fresh coat with the same unanswered question underneath?
