Hi Jenny
Just need to be careful of terraced houses where the cures need to be placed at ground level on each level. As dowsing you get he answer to the question you ask, make sure that you have in mind the whole house or level etc when you ask your questions.
I try to place the cures outside, where possible but walk right around the house to double check as sometimes the weaker stress lines hidden by the stronger ones and can be found on the second lap around the house ;-)
