Deck safety should be your ultimate deciding factor when building and maintaining your deck.

90% of deck collapses start when the joist of the deck disconnects from its mounting point on the house. Almost all deck collapses happen while the deck is occupied or under the weight of heavy snow. Railing accidents are even more common.

Falls accounted for 36,338 deaths, and 8.59 million nonfatal injuries, in 2017 in the United States.

These are problems that can be solved using the strongest materials and best installation practices known to science. Don't let you or your loved ones fall victim to this mistake. Make sure your deck is built to the highest standards and repaired as neccessary. Make sure you're safe while enjoying your outdoor living space.

"Many decks collapse before they reach their code-required design load... In fact, we're lucky that we don't load the decks to their capacity."

-Don Bender, Director, Composite Materials and Engineering Center WSU

Deck safety is achievable

Building a strong deck can be approached by managing three factors: Design, Materials, and Installation.

  • Design for Success: it all starts with planning your deck blueprints for durability and longevity.
  • Strong, Durable Materials: the sturdier the materials, the more your deck will hold and longer your deck will last.
  • Correct Installation: make sure the job gets done right. Whether you build it yourself or have 3 Brothers Decking provide full or partial deck contracting services. We offer complete deck contractor services, handling all this for you.
