Interior demolition costs $2 to $8 per square foot or $1,000 to $5,000 for an average demolition project. Obviously, the more you demolish and the greater the difficulty, the higher price. A small or simple demo project may include removing a single wall or the flooring in a room. A large or more complex demo project may include gutting the kitchen or removing a fireplace and chimney.
The final cost of your interior demolition will also be impacted by the labor you hire and the age of your home. Hiring a certified professional is more expensive, but worth the cost to ensure your demo is done safely, especially in an older home that may suffer more damage during demolition.
Finally, as with any project, there may be unforeseen expenses like mold remediation or asbestos removal that can greatly increase the final costs. An experienced demolition contractor is better at inspecting the property and pointing out potential issues than an inexperienced crew or homeowner.
