Concrete Demo Cost per Square Foot Guide

Understanding Concrete Demo Cost per Square Foot for Trade Professionals

For construction professionals, understanding the concrete demo cost per square foot is crucial for accurate project budgeting. Costs typically range from $3.50 to $10.00 per square foot, depending on factors like slab thickness, reinforcement, and site access. This guide provides detailed insights into these variables, helping you make informed decisions.

Why Square-Foot Pricing Matters

Square-foot pricing offers a standardized method for comparing bids and forecasting budget impacts. It helps contractors align costs with project dimensions, ensuring transparency and accuracy.

Typical Residential Ranges

In Southern California, concrete demo costs generally fall between $3.50 and $10.00 per square foot. Key factors include:

Slab thickness (e.g., 4" patio vs. 8" garage floor)
Reinforcement density (mesh, rebar, or post-tension cables)
Access constraints (tight side yard vs. open driveway)

Breaking Down the Concrete Demo Cost per Square Foot

Component Cost:

Labor: 30-45%
Equipment: 20-35%
Haul-off & disposal: 20-30%
Overhead & profit: 10-15%

CountBricks tracks these categories in real time, adjusting for changes in fuel surcharges and landfill rates.

Key Factors That Shift Pricing

Slab thickness: Each extra inch can add 10-15% to demo time.
Reinforcement: Cutting rebar increases blade costs.
Concrete strength: Older mixes demo faster than newer, stronger slabs.
Embedded utilities: Jackhammering around plumbing adds labor hours.
Site access: Difficult access may require specialized equipment.
