1. Observe and protect
Document the Columbia property's symptoms, when they show up, and what's already been tried, and limit damage further where it's safe.
2. Evaluate the house and site
Whether a Columbia basement wall is wet from downspout runoff, poor grading, rising groundwater through sandy fill, a settlement crack, or Sandhills humidity changes what actually needs to be done about it.
3. Define a written scope
For a Columbia project, get prep, protection, materials, access, permits, testing, cleanup, restoration, exclusions, and change-order rules in writing.
4. Compare providers
Look past the total number -- compare how each Columbia proposal reasons through the diagnosis and where it draws its boundaries.
5. Inspect closeout
Before calling a Columbia project finished, confirm testing, cleanup, documentation, warranty terms, and remaining maintenance duties.
