If you feel you need to clear your home there are things you may try, please do not spend your hard earned cash on these people, whose links I have provided, for educational purposes. Whatever you do is going to be just as effective as any of these people will, or can do, they have no magical powers. There are sites on the Internet that will suggest actions you can take to help you clear your own home. What I have told people is to, show no fear, and tell them to leave, let them know they are not welcomed in your home. There is no guarantee that anyone can clear a home.
" House clearings are completed with the best intentions but performing a house clearing will not guarantee that paranormal activity will cease." (yet they take your money)
