1. Observe and protect
Note the symptoms, avoid making things worse if it's safe to hold off, and pull together the home's relevant history.
2. Evaluate the house and site

3. Define a written scope
Put preparation, protection, materials, access, permits, testing, cleanup, restoration, exclusions, and change orders in writing.
4. Compare providers
Verify credentials, then weigh how each proposal reasons through the job, not just its total.
5. Inspect closeout
Confirm testing, cleanup, paperwork, warranty coverage, and any maintenance left to you.
