Inspect deck for rot and loose fasteners

Difficulty: easyTime: 30 mins

Why it matters

Deck collapses cause hundreds of injuries annually, almost always due to rotted ledger boards or posts that went uninspected. A probe test takes minutes; a deck replacement costs $10,000–30,000.

Stop forgetting to do this.

How to do it

  • 1

    Use a screwdriver and probe the deck boards, posts, and especially the ledger board (where the deck attaches to the house).

  • 2

    Soft spots where the screwdriver sinks in indicate rot.

  • 3

    Check all fasteners for corrosion and loose connections.

  • 4

    Look under the deck at the beam-to-post connections.

  • 5

    Any rot at structural elements warrants a professional evaluation.
