Question – How healing expenditure is decided?

As I believe in vastu without dismantling, as less as possible expenditure is suggested, which is generally very less as compared to vastu with dismantling things, which can cost from 5 lac to more than 25 lac. In certain cases.
Healing will be comprised of energised vastu items or spell busting healings methods.
Therefore Healing fee will be charged according to the intensity of the problems detected in a particular property.

Question – Can all vastu healings  be performed without dismantling?

Yes in majority of cases dismantling can be avoided and other vaastu healings can be done, but there are cases in which it is mandatory to dismantle the things and made new in an appropriate manner.
