Step 1 -- document conditions
Record the symptoms, limit any further damage where it's safe, and gather relevant background.
Step 2 -- evaluate the property
The visible growth is one piece; a complete plan also weighs water entry, humidity, material condition, containment, and post-work verification.
Step 3 -- put it in writing
A written scope should cover preparation, protection, materials, access, permits, testing, cleanup, restoration, exclusions, and change orders.
Step 4 -- evaluate proposals
Verify each provider's credentials and compare the reasoning behind their proposal, not simply the bottom line.
Step 5 -- confirm the closeout
Testing, cleanup, documentation, warranty terms, and ongoing maintenance responsibilities should all be verified at the end.
