Usually, a house is only dismantled if the owner wants to build a new and better structure in the same location. Though even with this in mind, many construction companies are still trying to save the structure as much as possible, believing that it will speed up the completion of new buildings.
These building repairs are usually avoided whenever possible because it is a huge task that has certain requirements that must be met by the construction labour hire to accomplish this task.

Destroy the house when the structure or foundation is no longer strong. This can be due to a number of reasons including the natural movement of the soil, the growth of tree roots, or the fact that the structure is not constructed with good stability. To avoid risk, it is always better to destroy structures than to leave them alone to prevent people from living in them.
Destroy the house when the place is no longer safe. The frequent movement of terrestrial tectonic plates meant that houses were built in areas that were endangered, which was recommended to be demolished as a precaution.
Destroy the house if there is water damage. Excessive and prolonged exposure to moisture can definitely damage the structural integrity of a building. It also promotes the growth of harmful fungi. Repair is usually not sufficient to deal effectively with this type of damage. Construction from below is required, and the dismantling of old structures is also mandatory.
