In any case, the following are good home cleaning techniques.
(1) Bring in a cleaning team and get the house cleaned top to bottom.
(2) Bring in some instruments that will induce repetative vibrations - like tibetan temple chimes. This can just be taped, and play the tape in each room, including basement and attic. This will "erase" vibratory recordings in the house physical structure by "overwriting" them.
(3) Bring in a minister to pray and bless the house. Some pagan traditions, as well as formal religious traditions, have effective techniques. If Christian, the Catholic and Evangelical/Charismatic techniques are optimal.
(4) This may sound unusual, but if the events are poltergeist phenomena (caused by a former and not a current resident) and NOT due to a ghost, you can "love" the house. Make sure the house knows you "love" it and appreciate it, and ask the house to stop the activity. It will. In this case you only have to execute step 1 and this step, neither 2 or 3 are required. You will likely have to do this step several times, but should see a diminishment of the activity.
Caveat - if, however, the activity is due to emotional issues within your family unit, then none of the above steps will work. The house will just keep getting "overwritten" with current problems. And step 3 is useless in this case, because it is not applicable.
