Start the review with completed operations.
For All Other Specialty Trade Contractors, the saved research highlights completed operations, premises/operations liability at jobsite, employee injuries. Confirm how these arise in the actual operation, what controls are used and whether additional services change the proposed coverage.
Questions to ask
- What specific trade or trades does this contractor perform? (The NAICS code is a catch-all — underwriters will want the actual scope.)
- Is the work primarily residential, commercial, or a mix? What percentage of revenue comes from each?
- Does the operation involve any work at height — scaffolding, steeplejack, crane lifts, or rooftop work?
- Are there any sandblasting, chemical application (sealants, pool chemicals), or abrasive operations?
- Does the contractor own heavy equipment — cranes, lifts, pavers, compactors — and what are approximate values?
- Are subcontractors used, and does the contractor collect certificates and require additional insured status from them?
- What does prior loss history look like, particularly for GL, completed operations, and workers' comp?
- Are there any ongoing or recently completed large commercial or municipal projects with contractual insurance requirements?

Establishments in this class perform specialized construction trades that don't fit neatly into the other specialty trade categories — examples include fence installation, residential and commercial driveway paving or sealing, outdoor swimming pool construction, patio and brick/paver work, sandblasting, scaffold erecting and dismantling, crane rental with operator, steeplejack work, and manufactured home setup. Work may be new construction, additions, alterations, maintenance, or repair. Most operations are performed entirely at client locations with minimal fixed-premises exposure.
