1. Document and protect
Document symptoms at the Sandy Springs property, limit further damage where it's safe, and collect relevant history.
2. Evaluate house and site together
Unlike the fall-line cities south of it, Sandy Springs sits entirely in the Piedmont: granite outcrops close to the surface, red clay on top, and steep lots along the Chattahoochee where drainage and grading do most of the work a foundation plan has to account for.
3. Put the scope in writing
For Sandy Springs work, clarify preparation, materials, access, permits, testing, and change-order rules.
4. Compare proposals carefully
Compare the reasoning behind each Sandy Springs proposal, not only the total, and verify credentials independently.
5. Confirm before calling it finished
Before calling it finished in Sandy Springs, confirm testing, cleanup, documentation, and remaining maintenance responsibilities.
