Your deck is the perfect place to enjoy the warm weather with family and friends. And an unsafe deck could possibly collapse, causing serious injuries to you and your guests.
The number of deck failures and resulting injuries has been increasing at an alarming rate. Between 2000 and 2008, there were at least 30 deaths reported as a direct result of deck collapses, and more than 75 percent of people on a deck when it collapses are injured or killed. With 40 million decks in the United States that are more than 20 years old, it's important for homeowners to check their deck.
"The deck is the most dangerous part of the house," warns Dr. Don Bender, a deck safety researcher and director of the Wood Materials and Engineering Laboratory at Washington State University. "However through proper design, construction and maintenance, most deck failures are completely avoidable."

To evaluate the safety of their decks, deck owners should look for five warning signs that a deck is unsafe:
- loose connections like wobbly deck railing and railing balusters
- missing connections — the wood ledger board is not properly fastened to the house
- treated lumber is corroded
- rotted deck boards or deck railing
- cracks in either the deck boards or the supporting structure
The two critical areas in a deck collapse are typically the deck's connection to the house and the railings.
The North American Deck and Railing Association is dedicated to increasing public awareness of the necessity for regular inspection and maintenance of existing lumber decks and synthetic decks among others and proper installation of new decks.
A key element of enjoying your deck for years to come is making sure it is safe and code compliant. NADRA's "
10-Point Consumer Safety Checklist" is an efficient way to take a good look at the different parts of your deck, with an eye to what might need maintenance, repair or replacement. Safety first, fun second -- make sure your deck is safe to enjoy.

You might also consider a professional inspection. "A professional inspection will examine every inch of your deck, provide information on your deck's capacity limits, identify any dangerous problem areas and give you a map of what to keep your eye on in the future. If your deck is older, this might include a regular deck inspection schedule," says Mike Beaudry, executive vice president for NADRA.
Older decks require closer scrutiny. Many of these decks were built before code requirements were in place to protect consumers. Some of these decks may have deck-to-house attachments using only nails. If your deck is older, it is even more important to have it inspected by either a home inspector (NADRA recommends ASHI-certified home inspectors) or a knowledgeable deck builder (see the listing at nadra.org). NADRA member deck builders are required to adhere to a code of ethics and comply with state licensing and insurance requirements.
If you find your deck is not safe to enjoy, NADRA advises taking immediate action to have it repaired or rebuilt as necessary.
