1. Observe and protect
Record what's showing up, limit further damage anywhere it's safe to step in, and gather whatever history exists on the property.
2. Evaluate the house and site
A sound Charleston-area evaluation works through water category, elapsed time, cavities that can't be seen, electrical safety, and material porosity before any plan gets made -- and nothing here promises an emergency-speed response.
3. Define a written scope
Spell out preparation, protection, materials, access, permitting, testing, cleanup, finish restoration, exclusions, and change-order rules -- in writing.
4. Compare providers
Checking credentials is step one; step two is comparing the reasoning behind each Charleston-area proposal and where its boundaries actually fall, not just the number at the bottom.
5. Inspect closeout
Confirm the test results, cleanup standard, paperwork, warranty terms, and whatever maintenance responsibility remains with the homeowner.
