Document the condition
Note the location, when it began, how it's changed, and any past repairs. A few photos and simple measurements help the first conversation.
Read the local context
Look at what is already on the ground before adding to it. Existing walks and drives show how this particular lot has moved, and a consistent pattern of cracking tells you something a soil description cannot. Establish where storm water crosses the property, because new hard surface on a sloping lot redirects it and that is what turns a patio into a neighbor's problem. In the mill-district streets, check what the new work has to tie into, since older walks and foundations were built to earlier practice and rarely match a modern detail.
Ask what will be hidden
Excavation, compacted base, soil condition, thickness, reinforcement, slope, joints, curing, access, and runoff determine performance long after the surface is finished. Insist on a written scope that documents the prep work that will be invisible once the concrete is poured and cured.
Compare complete scopes
Weigh protection, access, materials, permits, testing, cleanup, exclusions, warranty terms, and change-order rules across every Rock Hill proposal.
What official local sources add
The stormwater program is the record that reaches this trade directly, because new flatwork adds impervious surface and changes where runoff goes on a lot that already has a mapped drainage path. Recorded easements are the practical half of that: they frequently run along the side and rear edges where a patio or a widened drive would naturally sit, and a slab inside one can be required to come out. Historic designation reaches concrete only where it is visible on a designated textile-era property, which is a narrow but real case downtown.
