Frequently asked questions
Frequently asked questions about subcontractor agreement calculator
Retainage (typically 5-10% of contract value) must usually be released within 30-90 days after final completion and acceptance. Some states mandate maximum retainage periods. Disputes over punch list items can extend release timelines.
Pay-when-paid clauses delay your payment until the general contractor is paid, typically adding 30-60 days. Pay-if-paid clauses (less common and unenforceable in some states) mean you only get paid if the GC gets paid, shifting non-payment risk to you.
Subcontracts typically allow prime contractors to terminate for convenience with 7-30 days notice. You are entitled to payment for work completed plus demobilization costs, but not anticipated profits on unperformed work.
Mechanics lien deadlines vary by state but typically range from 60-120 days after your last day of work or final payment request. Missing lien deadlines permanently waives your right to file, so track these dates carefully.
