Fixing concrete steps or building new ones
A hairline crack or a chipped corner on otherwise solid steps can often be patched, and I'll tell you if that's all you need. When the steps have sunk, tipped toward the house or broken up across several treads, the trouble is usually underneath, and a patch on top won't hold for long. That's when I'd tear them out and start over with a proper base, because the base is the one part you can't fix later.
