Frequently Asked Questions
How much should I mark up subcontractors?
Standard GC markup on subs is 10–25%. It compensates for scheduling, supervision, quality control, warranty liability, and payment float — you own the result even though the sub does the work.
Should sub quotes be itemized to clients?
Show scope, not sub pricing. Presenting raw sub quotes invites clients to shop your subs directly and question the markup that pays for your coordination and guarantee.
What should I verify before using a subcontractor's price?
Current license, liability and workers comp certificates, written scope inclusions/exclusions, and schedule commitment. A cheap sub who fails any of those becomes your most expensive line item.
