1. Observe and protect the property
Document the symptoms, limit further damage where it's safe to, and gather relevant history on the home.
2. Evaluate the house and the site
Salt air and humidity make the hidden layers, sheathing, the water-resistive barrier, window flashing, and clearances, matter more here than almost anywhere else, regardless of the finish material chosen.
3. Get the scope in writing
Preparation, protection, materials, access, permits, testing, cleanup, finish restoration, exclusions, and change-order terms should all be explicit.
4. Compare proposals carefully
Verify credentials and weigh the reasoning and boundaries behind each bid, not just the total.
5. Confirm before closing out
Testing, cleanup, documentation, warranties, and remaining maintenance responsibilities should all be confirmed.
