We are nearing the end of a major refurb and extension project. I had planned to get professionals in to clean before we moved our stuff and ourselves back in. But we are sooooo far over budget that I don't want to spend any money we don't have to. Is it something we can easily do ourselves? How bad a state do builders leave it in? Right now, as they are mid kitchen fitting, every single kitchen cupboard is full of debris, the dust is unbelievable, and I do not want to even look in our family bathroom which the builders have been using for months (we are living off site). So what is your experience of this?
