Check a contractor against the government authority responsible for the exact work at your address, then confirm insurance with the issuing insurer or agent. A license number printed on a truck and a certificate attached to an estimate are starting points, not completed checks. Match the business, the permitted work and the dates before you sign.
This method is for US homeowners and renters who have the landlord’s permission to arrange work. Requirements depend on location and trade. Fixorally provides repair-choice information; it does not verify contractors for you.
Start with the work, not the job title
Write a short description of the proposed work: for example, replacing a bathroom vanity, moving the sink supply and drain, and adding an outlet. That description may involve more than one licensing authority. “Bathroom contractor” does not tell you who is authorized to alter plumbing or wiring.
Ask your state licensing agency and local building department which credentials cover that description. Record whether the requirement applies to the business, an individual tradesperson or both, and whether a specialist subcontractor must perform part of the work. If an agency says no license is required, record its answer and the work described. Do not turn an unsuccessful name search into a conclusion that someone is operating illegally.
License, registration and certification answer different questions
A business registration can identify an entity without establishing permission to perform a regulated trade. A contractor license may have a class or scope restriction. A manufacturer training certificate addresses that manufacturer’s program; it does not establish local legal authority. Ask what each document actually authorizes and which body can verify it. A current license also does not establish workmanship quality, punctuality or suitability for your particular project.
New York City example: use the right lookup
NYC’s DCWP license-status page links to its public Search Business service, which does not require an account. Use it for a Home Improvement Contractor credential. For plumbing or electrical work, also consult the Department of Buildings’ construction-professional directory and license-search links. DOB identifies Master Plumber and Master Electrician licenses and provides disciplinary-record links.
These are separate checks. A remodeling company’s home-improvement credential does not answer who will perform the regulated plumbing. Outside NYC, locate the corresponding state, county or municipal authority rather than applying this agency arrangement nationwide.
Match the record to the party taking your money
Search by both number and business name. Compare the official record with the estimate and proposed contract: legal name, business address, credential type, status and expiration date. If the advertised name differs, ask how it relates to the licensed entity and verify that explanation with the authority. Do not accept another company’s license merely because the salesperson says they work together.
Ask who will supervise and who will actually do specialist work. Record subcontractor names before the job starts. If a status is expired, suspended or unclear, ask the agency what it means for this job. Save the result and check again near the start date if there is a long gap. An application receipt is not the same evidence as an issued credential.
Verify insurance beyond the certificate
The National Association of Insurance Commissioners’ contractor guidance advises obtaining liability and workers’ compensation documentation and calling the insurance company to verify coverage. Ask the contractor to have its insurance representative send current evidence directly to you. Obtain the representative’s contact details independently where possible.
Keep liability and workers’ compensation questions separate. Ask the issuer what protection each policy provides for the proposed operations and people doing the work, including subcontractors. If the contractor claims an exemption from workers’ compensation requirements, ask the responsible state agency what documentation establishes that exemption. Do not decide it from “I work alone.”
A certificate summarizes information; it does not rewrite the policy. New York’s insurance regulator explains this certificate limitation. Ask the issuer about the named insured, policy dates, limits and exclusions relevant to your project. If your building requires additional-insured status, have the insurance representative explain the necessary policy documentation rather than relying on a note added to a certificate. Your own insurer can help identify questions about your property coverage.
Copy this verification sheet
Use one sheet per company. “Awaiting confirmation” is a useful result; it keeps an unanswered question visible.
| Check | Record to complete |
|---|---|
| Job and authority | Address; exact work; agency; official lookup URL; contact; date checked |
| Credential | Legal name; number; class; status; expiration; scope confirmed by agency |
| People doing the work | Supervisor; specialist subcontractors; credentials checked separately |
| Liability insurance | Named insured; insurer; policy reference; dates; limits; relevant operations confirmed |
| Workers’ compensation | Issuer confirmation or agency-verified exemption; people covered |
| Confirmation trail | Issuer contact; date; documents received; questions still open; renewal needed before completion |
Make the next decision
Resolve identity, authorization and coverage gaps before treating a bid as ready to accept. Then assess relevant experience and references separately. Keep your sheet with the contract so a replacement subcontractor or changed start date triggers a fresh check.
