How to Hire a Contractor You Can Actually Trust
A step-by-step guide to verifying credentials, spotting red flags, and protecting yourself before any work begins.
Hiring the wrong contractor is one of the most expensive mistakes a homeowner can make. This guide walks you through every step — from the first call to the final payment.
The 6-Step Hiring Process
Every state requires contractors to hold a valid license for most trade work. Ask for their license number and verify it directly on your state licensing board's website. A legitimate contractor will hand it over without hesitation.
- Ask for the license number before any other conversation
- Look it up on your state's contractor licensing board website
- Confirm the license covers the specific type of work being done
Red Flags to Walk Away From
Questions to Ask Before Hiring
Are you licensed and insured for this type of work in this state?
Who will actually be doing the work — you or subcontractors?
Will you pull the required permits?
What's your estimated timeline and what could delay it?
How do you handle unexpected issues or cost changes?
Do you offer a warranty on your work?
Verify your contractor's license
Check credentials directly with your state licensing authority before any work begins. A valid license, general liability insurance, and workers' compensation coverage are the minimum you should require from any contractor.
Requirements vary by state and change often — the information here may not cover every licensing or insurance requirement that applies to your project. Always confirm current rules with your state agency or local building department.
