Hiring an unlicensed or uninsured concrete contractor to pour your driveway or patio could leave you liable for injuries, defective work, or both. Before signing any contract, you need a straightforward way to verify that your contractor has the credentials and insurance coverage to protect your project. Here's exactly how to do it.
Why License and Insurance Matter for Concrete Work
A concrete contractor's license proves they've met state or local education, testing, and experience requirements specific to their trade. Insurance—especially general liability and workers' compensation—protects you if someone is injured on your property or if the finished driveway cracks prematurely due to poor installation.
Concrete driveways typically cost $4,000 to $12,000 depending on size and finish. That's enough money to warrant serious due diligence before handing over your first payment.
Check State and Local Licensing Requirements
Licensing rules vary widely. Some states require concrete contractors to hold a general contractor's license; others only regulate larger projects over a certain dollar threshold.
Start here:
- Contact your state's contractor licensing board or department of consumer affairs. Search "[your state] contractor license verify" to find the official agency.
- Ask if concrete driveway work requires a license in your area. Some states exempt driveways under $1,000 or certain square footage limits.
- Request the contractor's license number and ask them to spell it out to avoid transcription errors.
Once you have the license number, search the official state database (usually available online). Look for the contractor's name, license type, status (active vs. inactive), and any disciplinary history or complaints. An active license is essential; suspended or revoked status is a hard stop.
Verify Insurance Coverage
Ask the contractor for proof of insurance before work begins. Specifically, request:
- General Liability Insurance: covers third-party bodily injury or property damage (minimum $1 million is standard; $2 million is better for larger jobs).
- Workers' Compensation: required in most states if the contractor has employees; protects you from liability if a worker is injured on your property.
Don't accept a verbal promise or a photocopy. Request an insurance certificate of insurance (COI) issued directly by their insurance company. The certificate should list your address as an "additional insured" for the duration of the project.
Call the insurance company's phone number listed on the certificate to verify the policy is active and current. Scammers sometimes provide fake certificates with outdated expiration dates.
Look Up Contractor Background and Complaints
Beyond licensing, research the contractor's reliability:
- Check the Better Business Bureau (BBB) for their rating and any filed complaints. Concrete work disputes often center on finish quality, drainage issues, or premature cracking—look for patterns.
- Search Google and Yelp for reviews specific to driveway or patio projects. Generic praise is less useful than detailed feedback ("properly graded," "excellent edge finishing," "stood up through three winters").
- Ask for references and actually call them. Ask if the driveway or patio is holding up and whether the contractor was responsive to warranty issues.
Request Written Contract and Warranty Details
Before signing, confirm the contractor's licensing and insurance status one final time. Then insist on a detailed written contract that includes:
- Scope of work (driveway size in square feet, thickness, finish type, drainage plan).
- Timeline and payment schedule (avoid paying the full amount upfront; typical splits are 50% down, 50% on completion).
- Warranty (most quality contractors offer 1-2 years for material defects or settling; longer is better).

Frequently Asked Questions
Q: What if my state doesn't require a license for driveway contractors? A: Request proof of liability insurance regardless. Ask how long they've been in business, check online reviews, and call at least two references. Licensing isn't available, so insurance and history become your verification tools.
Q: Should I pay for concrete work before it's finished? A: No. Use a 50/50 split at minimum—half deposit to cover materials, half on completion after inspection. Some contractors ask for a 10–15% deposit to reserve the date, which is reasonable.
Q: What warranty should I expect for a concrete driveway? A: Expect 1–2 years for material defects or settling; longer warranties (5+ years) for the concrete itself exist but may cost extra. The warranty should cover cracks wider than 1/8 inch and drainage problems.
