Other factors to consider
The price of doing an interior demolition will depend on different factors. Homeowners must consider these factors when planning major renovations requiring internal demolition.
- Size: The size of the areas to be demolished significantly impacts the final demolition cost. Since demolition costs $2 - $7 per sq. ft, a bigger space will attract a higher cost.
- Budget: The amount a homeowner is willing to spend can influence demolition as different services have different prices. A budget of $2000 is enough to gut a bathroom completely, but for total demolition of a 1500-square-foot home, you may need at least $10000.
- Age of the home: An older home will likely cost more to demolish due to hidden costs that may arise during the inspection.
- Complexity: Rooms, spaces, and materials that are more difficult to deal with will cost more to demolish. For instance, it costs more to do a demolition job in kitchens and bathrooms because these rooms typically have plumbing, heavy fixtures, and appliance hookups.
- Asbestos costs more to remove from a building because it is hazardous and requires a special team of professionals.
Renovating a home can be exciting, but homeowners must consider demolition costs while planning any major renovations.
