Engineered wood and solid wood after water exposure
Engineered and solid wood floors react more slowly than laminate but can still cup, gap or discolour after prolonged moisture exposure. Cupping, where board edges lift higher than the centre, is often a sign the wood absorbed moisture from below rather than above.
A wood floor that's cupped slightly sometimes recovers as it dries fully and evenly, but boards that have blackened or delaminated at the tongue and groove usually need replacing rather than waiting out.
