Finding a good contractor is not about discovering a single perfect review. It is a verification process: confirm the provider is appropriate for the work, compare equivalent scopes, document the agreement, and understand how changes and payments will be handled.

Quick Answer: The Wiserlist 10-Point Contractor Check
- Define the project before requesting bids
- Verify the required license and current status
- Confirm the contracting business name matches the license
- Ask about workers' compensation and general liability insurance
- Get multiple comparable written bids
- Check recent, relevant references
- Read the written scope carefully
- Understand permits and inspections
- Use a compliant written contract and payment schedule
- Document changes in writing
1. Define the Job First
Contractor comparisons fail when each bidder is pricing a different job. Write down the desired result, materials/quality level, known problems, and timing before soliciting estimates.
2. Verify Licensing Yourself
In California, licensing is generally required when a project requires a building permit, uses additional workers, or totals $1,000 or more in labor and materials. Verify status directly through CSLB rather than relying on advertising.
Also verify that the classification is appropriate for the work.
3. Check the Business Identity
The name on the proposal and contract should make sense against the CSLB record. If the salesperson, business name, or license holder differs, ask for clarification before signing.
4. Ask About Insurance
Ask whether the contractor carries workers' compensation for employees and general liability coverage. CSLB's consumer prescreening checklist specifically tells consumers to ask about these coverages.
5. Get Comparable Bids
CSLB recommends at least three bids and checking references. Give each contractor substantially the same project description so you can compare scope rather than just totals.
6. Check References the Right Way
Ask about projects similar to yours and recent enough to be relevant. Useful questions: Was the schedule realistic? Were change orders explained? Was the site kept reasonably clean? Did the final price track the contract? How were problems handled?
7. Read the Scope Line by Line
A good contract should specify the work, major materials, payment schedule, permit responsibility, and timing. Ambiguous phrases such as 'repair as needed' can create disputes unless the process and limits are defined.
8. Understand California Payment Rules
For most home-improvement jobs, the down payment is limited to $1,000 or 10% of the contract price, whichever is less, subject to a narrow bond exception. Progress payments should not get ahead of the value of work/materials.
9. Use Written Change Orders
Changes in scope, price, materials, or timing should be documented in writing. Do not rely on a chain of informal verbal approvals for substantial changes.
10. Watch for Red Flags
- Pressure to sign immediately
- Requests for unusually large upfront payment
- License number that does not verify
- Business name mismatch without explanation
- Vague or incomplete scope
- No written contract where one is required
- Refusal to provide references
- Cash-only pressure
- Price dramatically below comparable bids without a scope explanation
- Requests to misstate permit or project information
11. How Realtor Recommendations Add Context
A Realtor recommendation can be useful when the agent has actually observed the contractor's performance in transactions. Wiserlist should show recommendation context—used personally, used for a client, type of job, location, responsiveness, and whether the Realtor would use the provider again.
12. Wiserlist's Opportunity
The strongest Wiserlist profile should combine identity, category, service area, license verification fields, insurance self-reporting/verification status, Realtor-use signals, consumer reviews, project types, photos, and response/availability information.
The Bottom Line
A good contractor is not identified by one rating or one recommendation. Vet the license, business identity, insurance, scope, bids, references, payment terms, permits, and written change process as a system.
