A demolition invoice is used by demolition contractors and companies for quoting or charging customers for the safe and organized destruction of their home or building. Large demolition jobs typically rely on bids, whereas residential homes are often requested by the homeowner; both types of structure are often priced on square footage, with the accessibility of the structure, the age of the building, and the risk all affecting the cost per square foot.

Demolition makes up a set of tasks that, with the help of science, mathematics, and specialized engineering, result in the precise and controlled destruction of commercial buildings and residential homes. A Building is typically demolished if it poses as a structural safety hazard or the land in which the building sits on is required for other purposes.
Types of Demolition
- Interior Demolition – Includes the removal of ceilings, fixtures, walls, and other non-structural building components. Primarily used for small-scale work such as renovation.
- Partial Demolition – Removes sections or entire areas off of buildings while leaving the core structure of the building intact.
- Total Demolition – The complete destruction of the building – often including the foundation. Can be achieved using a variety of methods, including the use of heavy-duty mechanical equipment (high-reach excavators, wrecking balls, skid steers, and concrete crushers), or by implosion (the use of controlled explosives). Deconstruction is another common method of completely removing a building – although not considered a type of demolition due to differing processes.
Implosion is commonly what the general public associate demolition with – however, according to R.Baker & Son, a provider of industrial services in New Jersey, implosion makes up just one percent (1%) of all demolition projects. However, for larger commercial jobs requiring the demolition of large office, apartment, or skyscrapers, implosion is far more commonly employed.
While demolition and deconstruction achieve a similar end-goal, which is the partial or complete removal of manmade structures both large and small, the way the methods achieve said building removal differs greatly.
Demolition focuses on the removal of a building through the most expedited of means, typically foregoing the recycling or reusing of any materials within the building. To salvage part of the building before demolition, workers often soft-strip the building. This involves the selection and removal of valuable items within the building, which can include appliances, doors, fixtures, and other objects.
Deconstruction involves the step-by-step removal of the home or building, taking each material of the building into consideration for recycling or other re-use purposes. The method requires a considerable amount of labor in comparison to demolition due to the piece-by-piece approach it demands for. According to the Delta Institute, up to seventy percent (70%) of a residential home can be recycled during this process. To state it simply, the process of demolition excels in speed and labor efficiency, whereas deconstruction extracts more value from the building, but takes considerably longer to execute.
The best method of locating a reputable demolition contractor is through friends, family, or trusted acquaintances who have had experience with a demolition company first-hand. As a second option, using Google Maps can display nearby demolition companies and their reviews.
