The Palo Alto check
Older decks here often carry decades of seasonal cycling — wet winters, bone-dry summers — which loosens fasteners and opens butt joints long before the boards themselves fail. A board soft at the screw holes or joints is done; a board that flexes underfoot usually means the joist below, not the board.
Next step
Worst boards straight down, the full deck from a corner, one shot underneath if reachable — send through the form. Board count and access set the price; photos establish both.
