The chairs come out of the garage. The table gets wiped down. The deck itself deserves a look before it becomes the busiest room in the house.

This is a homeowner observation list, to use from stable ground or another safe vantage point. It is not a reason to crawl beneath an unstable deck, lean hard on a guard, or bounce on the boards to see what happens.

Start where the deck meets the house

Look for a widening gap, staining below the connection, displaced flashing, or a section that appears to be pulling away. Photograph changes from the same position so a professional can compare them. On one spring visit, the homeowner's older photo showed the gap beside the siding had grown; the fresh stain on the deck had made it much harder to notice in person. We kept the deck out of use while the connection was assessed. A photograph with a date was more useful than a guess about how long it had looked that way.

Simpson Strong-Tie's connection guide treats the deck as connected parts, including the ledger, posts, beams, joists, and guards. A sound walking surface does not answer every structural question.

Make one careful circuit

  • Posts: visible leaning, splitting at connections, or deterioration near the base.
  • Hardware: missing fasteners, heavy corrosion, loose brackets, or connections pulling apart.
  • Walking surface: broken boards, raised edges, and changes in level.
  • Stairs and guards: damaged supports, loose components, and an obstructed landing.
  • Water: persistent damp areas and runoff collecting against the house or supports.

Know when the checklist ends

If the deck is visibly shifting, separating from the house, or has a failed support or guard, keep people off it and arrange a qualified assessment. Do not host the party first and book the inspection for Monday.

NADRA's evaluation guide is intended for deck professionals. That distinction matters: concealed decay and inadequate foundations can remain invisible during a tidy-looking walkaround.

Bring useful evidence to the visit

Gather the approximate age, any permit drawings, repair history, and photographs of what changed. Mention a new hot tub, roof, or heavy planter before discussing cosmetic repairs. Include when the movement or noise began, whether it followed winter, and which part of the deck it affects. You don't need to diagnose it or recreate it for a video. Those details help the assessor decide what needs opening up and what records to bring.

You may need a repair rather than a whole new deck. Once the immediate concerns are assessed, the next question is whether the existing frame is worth keeping. That decision is easier before you've fallen in love with a new board colour.
