1. Observe and protect
Document what you see, avoid worsening it where it's safe to wait, and collect the home's history.
2. Evaluate the house and site
Moisture behind the siding, chalking, failed caulk lines, and sun exposure are what actually dictate preparation and coating choice.
3. Define a written scope
Put preparation, protection, materials, access, permits, testing, cleanup, restoration, exclusions, and change orders on paper.
4. Compare providers
Verify credentials and weigh the reasoning behind each proposal, not just the number at the bottom.
5. Inspect closeout
Confirm testing, cleanup, documentation, warranty terms, and any maintenance that becomes your responsibility.
