Id let her sort it out, she should ring someone to come round to have a look at it and pay them herself without you having anything to do with it. Could easily explain to her that you would like to keep living in the place, hence why you want it all sorted cos you're there for the long run.
We moan like hell about our place, any little niggle, they still asked if we wanted to stay on, but we dont, we just want our flat none smelly, warm and nice.
