When most people think of demolition, they envision a wrecking ball smashing into the side of the building or explosives imploding a building within seconds. However, there are other subsets of demolition to note as well. One of them is interior demolition - and it's much more common than you may think.


As the name implies, interior demolition consists of demolition that occurs within a building without the end goal of bringing the entire structure down. In this post, we'll discuss everything you need to know about interior demolition - from when it's needed, the process involved, safety risks, types of projects, prospective costs, and more. Read on or contact Alpine Demolition today to learn everything you need to know about interior demolition.

What is Interior Demolition?

Fitting to the name, interior demolition is the practice of demolishing either part or all of a building's interior. Yet, it's more than just tearing things out - it involves careful planning and removal of internal structures to ensure that the building stays structurally intact. Unlike total demolition, which consists of taking down the entire structure, interior demolition is done in a way where just the interior is affected, while the building's outer shell stays unharmed and in place.


Interior demolition also differs from renovation. Renovation often involves removing flooring material, materials, and other building features. An interior demolition often involves all of this too, but the big differentiator is that it consists of altering the structure. In this sense, a renovation or redesign often follows interior demolition. Interior demolition often includes removing flooring, ceilings, and walls to reshape the space and make it suitable for the purpose that is envisioned.

When is Interior Demolition Needed?

Interior demolition is often needed when the structure of a building is still in good shape, but the interior space needs significant updates or improvements. Rather than razing the entire building and starting from scratch, it's often much easier and much cheaper to alter the interior space.


Interior demolition is common in commercial environments, including office buildings, retail, and even some industrial settings. It's also common for a new owner to acquire a building or piece of property and want to repurpose it.

Is Interior Demolition Safer or Riskier than Outside Demolition?

Both interior and full demolition come with their fair share of safety risks. However, in many ways, interior demolition is the more dangerous of the two. This is because workers are operating in more of a confined environment than with a full demolition. Additionally, there's the risk of striking utilities and the potential of a floor collapse if there's structural instability, two major threats that can cause significant injury or potentially even death.


These safety hazards underscore the importance of proper planning when it comes to any type of demolition, and interior demolition is no exception.

Types of Commercial Interior Demo Projects

As we said earlier in this post, interior demolition may be done for several reasons. Some of the most common include:


  • Fitting out new office space
  • Fitting out new commercial retail space
  • Repurposing an existing building
  • Restoring a historical building
  • And more!

The Process of Commercial Interior Demolition

Every interior demolition project starts with a plan. Without a proper plan, you're risking the safety of your workers who will be executing the project as well as the structural integrity of the building. Hence, the first step in any interior demolition process is careful planning.


From there, the process often consists of a few key steps. These are:


  • Flooring: The floors are often the first thing that's demolished. From old carpeting to outdated tiles or simply having to remove the flooring to properly address any issues with the subfloor, it's often the flooring that comes up first.
  • Wall demolition: Open floor plans are popular these days - and one major trend in interior demolition is ensuring that walls come down to facilitate more openness. However, you can't just go into a building with the right tools and equipment and start tearing out walls. This step must be done with planning and care. Ventilation, plumbing, and electrical often run in wall cavities. Some frames even act as support beams. If you don't know what you're doing and start tearing out walls, it could end up being a major problem.
  • Asset removal: Depending on the environment, there may be some key assets that are crucial to the property that you have to delicately dismantle and remove. In other cases, like demolition for a historical renovation, there may be key artifacts that need to be properly handled and removed for preservation purposes.

How Much Does Interior Demolition Cost?

Like any type of demolition project, the cost of interior demolition largely depends on the size and the scope of the project. Generally speaking, interior demolition is estimated to cost anywhere from $4 to $8 per square foot. Again, the cost largely depends on the scope of the demolition and the scale of what's being done.


Compared to a full demolition that involves bringing the entire building down, interior demolition is often much more affordable.
