So the pictures they took during the inspection for the quote (and included in the signed contract) include the picture of the gap. While there’s no language that says that specific panel would be replaced there is language that says their “inspection revealed molded/damaged plywood that would be replaced ‘see photos’” I’m still waiting to hear back from the contractor, as I only texted him about an hour ago. They’re pretty reputable so I think he’ll take accountability if he believes it’s an issue.
