Frequently Asked Questions

Why add a waste factor to materials?

Materials are rarely used with 100% efficiency. Cuts, drops, defects, and mistakes happen. Adding a 10-20% waste factor ensures you aren't paying out of pocket for inevitabilities.

What is the difference between markup and risk buffer?

Markup is for overhead and pure company profit. Risk buffer is a contingency fund for this specific job (e.g., discovering rot behind a wall). If the risk buffer goes unused, it's bonus profit.

Accurate Job Costing for General Contractors

Estimating construction jobs accurately is the difference between outlasting the competition and bankruptcy. The biggest mistake new contractors make is forgetting to bill for 'soft costs' like driving time, planning, and inevitable project risks.

Protecting Your Margin

By explicitly separating hard costs (materials and labor) from your risk buffer and markup, you can confidently lower your price if a client pushes back without accidentally eating into your operational costs.
