Why water, structure, façade, building systems, and documentation gaps can change the diligence conversation.
Water tells a broader story
Staining, sealant failure, roof history, below-grade moisture, and localized repairs can point to an active issue, a prior event, or a larger envelope pattern. Interviews and documents help interpret what the walkthrough reveals.
System age needs operating context
Age alone does not determine remaining life. Maintenance, loading, redundancy, controls, replacement history, and observed operation affect both risk and planning horizon.
Missing information is itself relevant
Absent drawings, incomplete repair records, limited access, and unavailable testing can constrain conclusions. Material limitations should be visible so the client can decide whether to seek more information.
