Before the first call
- Describe the job and ask whether it is within their scope and service area.
- Check the credential with its issuing authority and ask what applies where the work will happen.
- Ask about insurance, availability, who will do the work, and a written scope.
- Ask about callout fees, labor or fixed rates, materials, cancellation and any estimate charge.
Verification Overview & Key Takeaways: How to Check Official Credentials
Every listing on HomeCrafto is compiled directly from official state and municipal licensing rosters rather than paid lead-generation feeds. Before signing a work order or paying a deposit, homeowners should confirm that the contractor’s credential number is active, verify that the license classification covers the specific trade scope required for the job, and request a current Certificate of Insurance (COI) directly from the issuing insurance carrier. Independent verification protects your property and ensures compliance with local building codes.
How do you verify a contractor license number and insurance on official portals (FAQ)?
You can verify active license standing and consumer protection rules directly through official government portals, including Washington L&I Contractor Verify, the California Contractors State License Board (CSLB), the Connecticut eLicense Portal, USA.gov State Consumer Protection Offices, and FTC Home Improvement Consumer Guidance. Always confirm municipal permit requirements with your local building department before work begins.
