Average demolition cost per room

Living room 

Demolishing a living room costs an average of $4 – $6 per sq. ft.  The costs will go up if fixtures and floors need to be removed in addition to the walls. The presence of fireplaces and hazardous substances like asbestos and lead paint will also drive the costs up.

Kitchen

It costs an average of $500 – $3000 to demo the kitchen of a small-sized home. Interior kitchen demolition costs fluctuate upwards or downwards depending on size, local regulations, materials to be removed, and other associated fees. Remodeling the kitchen requires another $13500 to $38000.

The work to be done may also drive up the costs. For instance, it costs more to demolish a kitchen when the workers are required to be extra careful not to damage pre-existing fixtures and materials. Other factors that may increase kitchen demolition costs are pipe removal, tile removal, and fixture removal.

Bathroom

Interior bathroom demolition costs an average of $550-$1,500, with prices as high as $2300. Bathroom demo jobs are similar to kitchen demo jobs because they may involve fixture removal. Additionally, such jobs may require an inspector to check for lead and asbestos, which increases costs. 

Bathroom demolition costs are higher if the demo workers are required to remove tiles, toilets, bathtubs, showers, sinks, and piping. However, some bathroom fixtures can be recycled or sold to scrap yards to offset some of the demolition costs. Once the demolition is complete, it may cost $6600 – $16500 to remodel a bathroom. 

Bedroom

Basement demolition jobs typically cost more if they require the removal and replacement of concrete flooring. Demolition costs will also be higher if there is structural damage to repair and if the basement floor requires leveling. 

Sewage and mold issues will also drive basement demolition costs, as these require a professional inspection. Removing fixtures such as the HVAC will increase labor, disposal, and recycling costs. 

Interior basement demolition clears the way for a remodeling job which may then cost $12200 to $33000. These costs include demolition, flooring, insulation, carpeting, ceiling updating, and fixture placement. 

Interior wall demolition cost

Knocking down nonbearing interior walls costs an average of $0.30 to $6.40 per square foot, totaling about $1200 – $5000. Homeowners expect to pay approximately $2500 to demolish a 120 sq. ft loadbearing plaster wall (with little or no utility lines). 

The presence of electrical wiring and piping will drive costs up because the job will require more care and time. The final costs will depend on the material used to build the wall.

Recycling costs

The national average cost for recycling materials from demolition is $6 – $8, depending on the service provider. Recycling is important because it helps reduce the number of construction materials in landfills. Recycling can also help homeowners offset some demolition expenses. 

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.

Summary

Renovating a home can be exciting, but homeowners must consider demolition costs while planning any major renovations. The cost of interior demolition varies depending on the size of the area, materials, and complexity of the job. The national average for interior demolition costs is $1000 – $5000, but this price can go up to several tens of thousands.
