Demolishing a house can take anywhere from a day to several days. The building is usually pulled down using large hydraulic equipment like an excavator. Wrecking balls are also used but these are less easily controlled and often less efficient than an excavator.

The excavator tears apart wooden floors and sub-flooring during total demolition of a residential structure in just 40 seconds. Granted, the neighbor who captured the tear down sped up the video but it’s still exciting to watch this excavator turn this house to a pile of rubble in under a minute:
