Concrete is hard to fix once it sets, so the crew matters more than the lowest number. ConcreteNear doesn’t host star ratings. Here is how to check a contractor yourself.
Check the license
Most states (and some cities) license contractors. Look the company up on your state contractor board’s website and confirm the license is active and matches the business name on the estimate. Many ConcreteNear listings show the license number we found and link the source.
Ask for proof of insurance
Ask for a certificate of general liability insurance and confirm workers’ compensation coverage where your state requires it. If an uninsured worker is hurt on your property, you could be exposed.
Get written estimates you can compare
- Area, thickness and the concrete strength (psi) to be used.
- Base preparation: excavation depth, base rock type and compaction.
- Reinforcement: mesh, rebar size and spacing, or fiber.
- Control-joint layout, finish (broom, stamped, exposed aggregate) and sealer.
- Demolition and haul-off of old concrete if needed — see demolition & recycling.
- Who pulls the permit, and who calls 811.
- Payment schedule, start date and what happens if weather delays the pour.
- Any warranty, in writing.
Red flags
- Pressure to decide today or pay most of the price up front in cash.
- No written contract, or a quote with no thickness or base details.
- “Leftover concrete from another job” offers from crews going door to door.
- Unwillingness to provide a license number or insurance certificate.
Questions worth asking
- How will water drain off the new slab?
- Where will the control joints go?
- How will you cure it, and what do I need to do afterward?
- How soon can we walk on it and drive on it?

Common questions
How do I check if a concrete contractor is licensed?
Search the contractor’s name or license number on your state’s contractor licensing board website. Requirements vary by state; some licensing is handled at the city or county level.
How many estimates should I get?
Getting more than one written estimate with the same scope lets you compare thickness, base, reinforcement and finish line by line, not just the price.
