Hi don't know if anyone can help about five years ago my mother moved to a new house shortly after she started experiencing a burning smell at first it smell like burnt toast then to a really pungent burning it moved around the room but you could not smell it elsewere in the house, she has since moved again and is still experiencing it. I myself about nine months ago came in from work and the same burning smell I have had this a few times over recent months, and it is usually around eleven at night any ideas as to what this is.
