1. Observe and protect
Document symptoms, limit further damage where it is safe to do so, and collect relevant history.
2. Evaluate the house and site
Visible growth is only part of the problem. A durable plan addresses water entry, humidity, material condition, containment, and post-work verification.
3. Define a written scope
Clarify preparation, protection, materials, access, permits, testing, cleanup, finish restoration, exclusions, and change-order rules.
4. Compare providers
Verify credentials and compare the reasoning and boundaries behind each proposal—not only the total.
5. Inspect closeout
Confirm testing, cleanup, documentation, warranties, and remaining maintenance responsibilities.
