The Comprehensive Guide to Costs for Interior Demolition

Updated 06/02/2024

What is Interior Demolition?

Interior demolition is all about tearing down the inside parts of a building while keeping the outside intact. This could mean ripping out drywall, flooring, internal walls, fixtures, and other components to make way for your new design or layout. It's a crucial step to make sure your remodel goes smoothly. Interior demolition can also include more specialized tasks such as removing built-in cabinetry, taking down load-bearing walls with the help of a structural engineer, and even stripping out old electrical wiring and plumbing systems. It's not just about smashing things apart – but needs to be correctly in a way that sets the stage for the next phase of your project.

Factors Influencing Interior Demolition Costs

Costs can vary based on where you are and what your specific project needs, but here are some key factors that generally affect interior demolition pricing:

  • Size and Scope of the Project: The bigger the area or the more rooms involved, the pricier it gets. Knocking down an entire floor or multiple rooms will take more time, labor, and materials than just one room.
  • Materials Involved: Different materials mean different challenges. For example, breaking down concrete walls is a lot tougher and more expensive than taking out drywall. And if you’ve got hazardous materials like asbestos, that’s going to add to the cost due to added time, preparation and carefulness.
  • Accessibility: If the space you’re demolishing is hard to get to, it could bump up the price. Think narrow stairways, tight workspaces, or no nearby parking – all of these can make the job longer and professionals will often factor this into the job cost.
  • Waste Removal: Getting rid of the debris can add a chunk to your total cost. Some materials can be recycled, which might save some money, while others need special handling and disposal methods.
  • Labor Costs: Labor rates can vary depending on where you live and the expertise of the crew you hire. Skilled workers might cost more, but they can also do the job faster and better, potentially saving money in the long run.

Average Costs of Interior Demolition

When considering the costs, here’s a rough idea of what you might expect to pay for interior demolition:

  • Small projects (e.g., a bathroom or single room): $500 - $3,000. These are smaller jobs with less labor and fewer materials involved. Usually this will be for a client wanting to remodel one space in their home.
  • Medium projects (e.g., multiple rooms or an entire floor): $4,000 - $15,000. More rooms mean more work, hence higher costs. This is the typical range for homeowners doing an entire remodel.
  • Large projects (e.g., multiple floors or dealing with specialized materials): $16,000 and up. Big projects need extensive planning and resources, driving up the price.

Remember, these are ballpark figures. Your actual costs can vary based on the specifics of your project, location and crew you choose to hire.

Preparing for Your Interior Demolition

  • Secure Necessary Permits: Make sure you’ve got all the required permits before you start. Check with local authorities or get a pro to help navigate the permitting process. Skipping this step can lead to fines or legal trouble.
  • Safety First: Ensure the area is safe for work. This includes checking for hazardous materials like asbestos or lead paint. If these are found, you'll need specialized removal to keep everyone safe.
  • Disconnect Utilities: Make sure to shut off all utilities (electricity, gas, water) to the demolition area before work begins. This step is crucial for avoiding accidents, so make sure you're able to test everything properly and have a clear signal before moving on.
  • Consider Recycling Opportunities: Materials like metals can often be recycled, which can reduce your disposal costs. Recycling is also a great way to minimize the environmental impact of your project instead of just having everything thrown in a dump trailer and mixed in with the rest of the project waste.


Interior demolition is usually a big job no matter the size of the project, but with the right planning, tools, and team, it doesn’t have to be overwhelming. By hiring a professional contractor, making a detailed plan, using the right equipment, and handling debris properly, you can keep your project on track and on budget.
