Concrete Contractor Materials — Frequently Asked Questions

Most concrete contractors mark up materials 30—45%. On a job with $1,880 in materials, a 38% markup adds $714 in materials profit. Contractors who order concrete directly from the plant and have trade accounts often receive 10—15% below retail, making their effective markup even higher when they bill at standard rates.
Yes — and it's expected. Concrete, rebar, gravel and forming materials all carry a standard contractor markup. With materials typically representing 40% of a concrete job, a 30—45% markup can add $600—$1,200 in additional profit on a $5,000 job. Volume buying and plant accounts significantly improve this margin.
Materials typically represent 35—45% of a concrete job's value. Ready-mix concrete is usually the largest cost, followed by reinforcement (rebar, mesh) and base preparation (gravel, sand). Jobs with decorative finishes may have lower materials as a percentage since labor and skill account for more of the total value.
Most concrete contractors provide a scope description (e.g., "4" reinforced concrete slab, 400 sq ft, broom finish") without itemising unit costs. This is standard practice. Providing a mix design spec and load count shows professionalism without exposing your supplier pricing. Reserve full itemisation for cost-plus commercial contracts where it's contractually required.
Concrete and rebar prices fluctuate with fuel and steel markets. Keep quotes valid for 14 days maximum and note this clearly. For large pours, get a confirmed price from your plant before submitting the quote. Build a 5—7% contingency into material costs for jobs starting more than 3 weeks out. This protects your margin without overcharging on most jobs.
