Fixing old concrete steps or replacing them
If your steps sit level, stay tight to the house and only have a chipped edge or two, a repair may be all they need. When they've sunk, tipped toward the house or cracked clean through, the ground under them has usually moved, and patching the top won't fix the ground. I'll tell you which one you've got while we're standing there, and if it's a patch job, I'll say so.
What shapes the cost of concrete steps
The biggest swings come from choosing precast or poured, how many steps there are, how tall and wide the set runs, and whether old steps have to be broken out and hauled away. Base work adds cost you won't see once the job's done. If the budget's tight, that's the last place I'd cut, because a nice finish sitting on a base that settles is a set of steps you'll end up replacing.
