Check end-grain for checks and rot, probe with an awl, and confirm straightness against a known flat reference. For metals, test with magnets and verify warping. Log defects, load ratings, and repair options so design intent, fabrication choices, and warranties remain confidently aligned.
Use certified kits or lab services for lead and solvent residue, avoiding heat guns or sanding until cleared. Demand disclosure from sellers, and prefer bare or mechanically stripped stock. Seal with low-VOC systems that honor patina yet create cleanable surfaces for hospitality-grade hygiene requirements.
