Rotting boards can point to moisture damage or wear, but a visual check can’t confirm the cause or how far it extends. Learn what to observe safely and when to contact a deck professional.

What may be causing the rot

Wood that stays damp can decay over time. Aging protective coatings, poor drainage, or limited airflow may contribute, but a professional inspection is needed to assess the boards and anything beneath them.

When to keep people off the deck

From the ground or another stable place, look for visible decay, loose boards, or areas that appear soft or sagging. Don’t step on or test a board that looks damaged. If boards are loose, several areas are affected, or the deck seems unstable, keep people off it and contact a qualified deck professional.
