We've been renting this flat for a few years. Until recently no massive problems, contacted the LL in Dec to say the mould in our bedroom has got worse this year despite opening windows and using expensive dehumidifiers. Their answer was to clean the mould with a special agent, use a sealant and re paint, which we did. Last month the mould is back, the windows are sopping wet every morning as they are old with wooden rather than PVC outside layers. Inspection done and agent said windows need replacing. Suddenly LL transfers maintenance to agents and they say LL is unhappy with our garden having one bin bag (full of clothes) in the garden so we assure them it's since been removed, show them pics of our clean and tidy garden. Then they're unhappy with us using the outside storage space, wany to know what we're storing and say its an eyesore for neighbours 🤨. I replied we are storing what we already told them, weights, gym equipment, garden furniture etc there, it was there when we moved in and if they had a problem with it, why build it in the first place? Their answer is we are using it excessively and gave us notice to leave. The only times we have called them previously is when the boiler stops working and instead of replacing they send round an unqualified friend to temporarily fix it. My 2yo DS has an ongoing cough and I'm sure it's related to mould. AIBU or is my LL?
