Factors That Impact Demolition Cost

Every demolition cost depends on the size and condition of your concrete slab. Understanding these factors helps you set clear pricing and avoid surprises in any project.

Thickness (Height): A thicker slab takes more time to break up and remove, raising removal costs.
Slab Width: A wider slab covers more area, driving up labor and disposal costs.
Reinforced Concrete: Slabs with rebar or mesh need extra tools and effort, adding to your concrete cost.
Concrete Access Challenges: Hard-to-reach demo sites slow crews and increase cost.
Haul Fees: Heavy slabs require more hauling, adding to your cost.

Frequently Asked Questions

How do I estimate concrete removal?
Concrete removal typically costs between $2 and $6 per square foot, with disposal fees running $50–$100 per ton. To estimate, first measure the slab’s area (length × width in feet) to get total square footage. Next, multiply that area by your local removal rate (e.g. 4"-thick slab at $4/ft² costs 100 ft²×$4 = $400). Finally, add disposal: for a 1-ton load, budget another $50–$100. Remember to adjust if the slab is reinforced—expect the higher end of the $4–$6/ft² range for rebar jobs.
How much does it cost to even out concrete?
Concrete leveling (mudjacking or foam) typically starts at $300 for small spots and can run up to $2,000 or more for larger areas. A-1 Concrete reports average stone-slurry grout leveling jobs cost $1,100–$1,500, while foam lifting ranges $5–$25 per square foot. To estimate, outline the repair area, choose your method (grout or foam), and multiply by the per-job minimum or per-ft² rate—and always get at least two quotes to compare materials and access fees.
