Decking Checklist: How to Know If Your Deck Needs to Be Replaced

Your deck should be your outdoor sanctuary—a place for morning coffees, weekend BBQs, and evening unwinds. But just like any part of your home, it needs a little attention from time to time. If it’s been a few years since you really looked it over, it might be time to ask: Does my deck need to be replaced?

Here’s a quick decking checklist to help you decide whether a simple repair will do or if it’s time to start fresh.

✅ 1. Wobbly or Loose Railings

Test your railings by giving them a gentle shake. If they move easily, it could be a safety hazard. While loose railings can sometimes be fixed with new fasteners or reinforcements, excessive movement may signal a larger structural issue.

✅ 2. Cracked or Splintering Boards

A few minor cracks are normal with age and weather. But if your boards are deeply cracked, splintering, or feel brittle underfoot, replacement may be your safest (and most comfortable) option.

✅ 3. Rotting Wood

Use a screwdriver to gently press into the wood, especially around the ledger board, joists, and posts. If it sinks in easily, you’re dealing with rot. Wood rot spreads quickly and compromises your deck’s strength—this is often a sign it’s time to replace.

✅ 4. Sinking or Shifting Footings

Are parts of your deck sloping or sinking into the ground? Shifting footings may indicate issues with your soil, drainage, or foundation. A sinking deck isn't just unsightly—it can lead to structural instability.

✅ 5. Rusted or Loose Fasteners

Screws, nails, and brackets that are rusted, corroded, or pulling away from the wood aren’t just an eyesore—they’re a warning. If many of your fasteners are in bad shape, they could be weakening your entire deck.

✅ 6. Mold, Mildew, or Algae

A green film might seem like just a cosmetic issue, but persistent mold or mildew often points to moisture problems. If it’s growing on the surface, it could be lurking underneath too—check joists and support beams.

✅ 7. Unsafe Stairs

Wobbly steps? Cracked treads? Loose railings? Your stairs are one of the most common places for injuries on a deck. If your stairs show signs of major wear or instability, it’s time to act.

✅ 8. It’s Over 15–20 Years Old

Even with regular maintenance, most wood decks have a lifespan of 15–20 years. If your deck is approaching or past this milestone, it’s worth getting a professional inspection—or considering an upgrade to a longer-lasting composite deck.
