Most calls about steps start with something you deal with every day. It might be a chipped edge, a step that's settled away from the house, or water pooling on the treads after rain. Behind most of that is the ground the steps sit on and where the water runs, so I look at both before I talk about concrete at all.
The price moves with how many steps you need, whether there's a landing, the finish you pick, how hard it is to get a truck or a machine to your door and whether the steps reach the street. The schedule turns mostly on poured versus precast and on any permit. Your written estimate spells out what's included for your entry.
If you're comparing bids, California's licensing board has a concrete contractor classification for people who form, pour, place, finish and install concrete, and a new set of steps is that kind of work. It's a fair thing to ask any contractor about before anyone starts digging.
