We are moving house next weekend, and I have just had a call from my landlord. She has given me the name of a cleaning company and a quote of £200 for them to clean our 2 bed maisonette when we move. I was going to clean the flat myself to save money, but she turned her nose up at this and said it wouldn't be as clean as if a professional cleaning company did it. She also said that I would need to make sure that there was no mould staining on the wall in our bedroom (one of the reasons we are leaving is the Mold problem). I'm worried that if I clean it, she could still say it wasn't clean enough and demand a company do it at my expense. Can she do this? And what if the mould has stained the paint and I can't get it off?
