1. Observe and protect
Write down what's showing at the Greenville property -- crack size, door and window behavior, timing relative to rain -- before anything gets covered up or repaired informally.
2. Evaluate the house and site
Piedmont clay swells and shrinks with the seasons more than most soil types, so a Greenville evaluation has to account for how that cycle has already affected the structure, not just the current snapshot.
3. Define a written scope
A solid Greenville scope covers prep, protection, materials suited to expansive clay, access, permits, testing, cleanup, and how any change to the plan gets priced.
4. Compare providers
Two similarly priced Greenville bids can rest on very different assumptions about cause and fix -- read past the total before deciding, and check credentials either way.
5. Inspect closeout
Before treating a Greenville project as finished, confirm test results, a clean site, documentation, warranty terms, and what upkeep is left for the homeowner.
