I'm currently unable to go home as my rented flat has a mould problem. It's in the shared main entrance and the hallway to my kitchen, and I have a 5 week old baby. The builder says the repairs will take a week however he's been to this particular flat before and the landlord refuses to deal with the mould in the entrance as it doesn't affect anyone. AIBU to think that it can affect my asthma and want it fixed? Or am I being ridiculous and demanding?
