Deck Safety: 5 Warning Signs of an Unsafe Deck

deck safety

Just like your home, your deck can’t be expected to last or keep you safe unless it’s correctly built and maintained. Most experts agree that the average life expectancy of a wood deck is 10 to 15 years, and estimate that millions of decks in the US may be presently unsafe. The good news, however, is attention to deck safety can prevent most deck collapses.

If you’re building a deck or already have one, you should know how to evaluate its construction to make sure it’s structurally sound and safe. Using the proper structural connectors and fasteners (like nails and screws) as well as regular maintenance are the keys to a safe, strong deck. It’s a good idea to inspect your deck annually to make sure all your connections are strong.

5 Warning Signs of an Unsafe Deck

Below are the warning signs you should look out for to determine whether you may need to repair, retrofit or rebuild your deck.

  1. Missing Connections

2. Loose Connections

Issues such as wobbly railings, loose stairs, or ledgers that appear to be pulling away from the home are all causes for concern.

 

3. Corrosion of Connectors and Fasteners

Home Safety Council on Deck Safety

We’ve teamed up with the Home Safety Council to educate families about the importance of deck safety and inspecting your deck once a year. In the following video, Meri-K Appy, president of the Home Safety Council, walks you through the five warning signs of an unsafe deck and shows you what a safe deck should look like.

Repairing or Retrofitting an Existing Deck

If you’ve determined your deck is unsafe, you’ll need to repair or retrofit it or, in some cases, rebuild it altogether. If rebuilding your deck is not feasible, there are improvements you can make on your own if you have the proper tools and hardware. However, some cases may require the professional services of an engineer and contractor. Just be sure that anyone you hire is licensed and has a good reputation. Once the work is done, remember to have it properly checked and inspected on a regular basis.
