What to look for
- Photos of driveways, patios or slabs they've poured
- Liability insurance
- Clear specs: thickness, reinforcement and base
- A workmanship warranty
- Reviews that mention few cracks and good drainage
Questions to ask before you hire
- How thick will it be, and what reinforcement will you use?
- How will you prepare and compact the base?
- Where will the control joints go?
- Is removing the old concrete included?
- How long before I can walk or drive on it?
Getting and comparing quotes
Ask every contractor to bid the same size, thickness and finish. Compare reinforcement and base prep, not just the price per square foot.
Red flags
- Won't put thickness or reinforcement in writing
- Skips base prep
- Suggests skipping permits for driveways
- Asks for full payment before the pour
