No honest driveway company should promise that concrete will never crack. What matters is proper preparation, joint planning, drainage, curing, and clear expectations before the work starts.
Questions to ask
Ask how the base will be prepared, where control joints will go, how drainage will be handled, when you can walk or drive on the concrete, and what maintenance the finish needs.
Why expectations matter
Concrete is a natural material. A good contractor reduces risk with preparation and communication instead of making unrealistic promises.
