When considering a home renovation or remodelling project, residential interior demolition is often a necessary first step. However, before diving into the demolition process, it’s essential to understand the real cost involved. Residential interior demolition cost can vary significantly based on various factors, and homeowners should be aware of the potential expenses to plan their budget accordingly. In this blog, we will provide a comprehensive breakdown of the real cost of residential interior demolition.

1. Scope of Demolition

The extent of demolition needed is a significant factor that impacts the overall cost. The more extensive the demolition, the higher the expenses. Consider the following aspects when determining the scope of demolition:

  • Partial Demolition: If you are only removing specific walls, fixtures, or features, the cost will be relatively lower compared to a complete interior demolition.
  • Full Interior Demolition: For a complete gutting of the interior, including walls, floors, ceilings, and fixtures, the cost will be significantly higher.

2. Labour Costs

Labour costs make up a significant portion of residential interior demolition expenses. The complexity of the project and the time required for completion play a crucial role in determining the labour costs.

For simple and small-scale demolition projects, the cost may be calculated on an hourly basis. For larger and more complex projects, contractors may provide a fixed quote based on the estimated time and workforce required.

3. Hazardous Materials Removal

Depending on the age of the property, there may be hazardous materials such as asbestos or lead-based paint that need to be removed before demolition. The presence of these materials requires specialised handling and disposal, which can add to the overall cost.

It’s crucial to have a thorough inspection of the property conducted before demolition to identify any hazardous materials and address them appropriately.

4. Waste Disposal

Residential interior demolition generates a significant amount of waste. Disposing of this waste properly is an essential part of the demolition process. The cost of waste disposal varies depending on the volume of waste and the local regulations for waste management.

Dumpster rental fees and landfill disposal costs are factors to consider when budgeting for waste disposal during interior demolition.

5. Structural Changes and Support Removal

If the demolition involves removing load-bearing walls or making structural changes to the property, additional engineering and support measures will be necessary. This can include the installation of temporary supports or reinforcement of other structures, which will add to the overall cost

6. Site Cleanup and Restoration

After the demolition is complete, there will be debris and dust that need to be cleaned up. The site may also require minor repairs and restoration to prepare it for the next phase of the renovation.

The cost of site cleanup and restoration should be factored into the overall budget for residential interior demolition.

7. Permits and Regulations

Depending on the local regulations and building codes, permits may be required for interior demolition. The cost of obtaining permits should be considered in the overall budget for the project.


Residential interior demolition cost can vary based on the scope of demolition, labour costs, hazardous materials removal, waste disposal, structural changes, site cleanup, and permits. Homeowners should obtain multiple quotes from reputable contractors and have a clear understanding of the project’s requirements before proceeding with demolition.

Proper planning residential interior demolition cost will ensure that the process is carried out efficiently and within the expected cost range. By considering all aspects and potential expenses, homeowners can proceed with confidence and embark on a successful interior renovation journey.
