My landlord is lovely. They are having some work done to the house I rent from them and the work requires scaffolding, which will be up for over a week. I'm a single mum with 3 kids and I have asked for the scaffolding to be alarmed. Apparently that costs a few hundred quid - Am I unreasonable to insist upon it? I don't sleep well at best of times (garden backs into alleyway) but should I just not be so anxious??
