7 Certificate of Insurance Mistakes That Get Contractors Booted Off Jobs
Published January 2026 6 min read
The seven mistakes
In rough order of frequency:
- Additional Insured by blanket endorsement when the GC's contract requires specific named AI
- Missing Waiver of Subrogation on Workers' Comp
- Primary & Non-Contributory language not on the GL
- Certificate Holder address doesn't match the AI endorsement
- Auto coverage shown but no symbol 1 / Any Auto checkbox
- Aggregate per location / per project not endorsed
- Cancellation notice clause not in line with the contract
How to avoid them
Send us the GC's insurance requirements page before binding. We'll align endorsements at issue — much faster than amending mid-job.
