National Deck Safety Month: Why It Matters and How to Keep Your Deck Safe

May is more than just the month when warmer weather arrives—it’s also National Deck Safety Month, a time to check, fix, and reinforce the outdoor space where we relax, barbecue, and create lasting memories. Spearheaded by the North American Deck and Railing Association (NADRA), this annual campaign is about one thing: safety. With millions of aging decks in the U.S., too many are one loose bolt or rotted beam away from a serious accident.

Decks play a bigger role in our lives than we often realize. They serve as outdoor extensions of our homes—spaces where we celebrate birthdays, enjoy quiet mornings, or simply gather with loved ones. But unlike indoor areas that get constant attention, decks are frequently neglected, even though they face the harshest weather. That’s why understanding the risks and embracing proper care is critical. In this guide, we’ll explore why deck safety matters, share expert-backed inspection steps, and show you how to keep your deck sturdy, stylish, and secure.

The Problem: Aging Decks and Overlooked Dangers

It’s easy to assume your deck is safe—until it isn’t. Over time, weather, wear, and neglect can turn a once-solid structure into a hidden hazard. According to NADRA, more than 30 million decks are past their intended lifespan. The Consumer Product Safety Commission (CPSC) reported over 20,000 injuries linked to structural deck failures in just a five-year span. One major culprit? Improper attachment to the home—a failed ledger board connection causes 90% of deck collapses.

Other dangers include loose or rusted fasteners, unstable railing systems, and decayed wood—especially on older decks made from untreated lumber. In regions with heavy rain or high humidity, the chances of rot and warping increase dramatically. Likewise, freezing and thawing cycles in colder climates can weaken critical joints and supports.

The good news: most of these issues are preventable with regular checks and maintenance. National Deck Safety Month exists to help homeowners do just that—and stay ahead of costly, avoidable repairs.

What to Inspect: 10 Key Deck Safety Checks

Performing a basic deck inspection doesn’t require a contractor’s license. Here are 10 key things you can check yourself:

1. Wood Condition: Look for signs of soft spots, cracks, warping, or insect damage in boards, posts, beams, and stairs.
2. Ledger Board & Flashing: Ensure the ledger is securely bolted to the house and properly flashed to prevent water infiltration.
3. Fasteners & Hardware: Replace any rusted, loose, or missing nails, screws, or brackets. Prioritize galvanized or stainless steel.
4. Railing Stability: Push and pull on railings to confirm they’re firmly anchored. They should be at least 36 inches high with baluster spacing under 4 inches.
5. Stairs & Handrails: Inspect for secure treads, strong risers, and graspable handrails. Watch for uneven steps.
6. Surface Cleanliness: Clear debris like leaves, which trap moisture and cause rot. Check for slippery mold, algae, or mildew.
7. Grill & Fire Pit Safety: Use a grill mat or spark screen to avoid scorching or fire. Keep flames a safe distance from railings and furniture.
8. Lighting & Electrical: Test all lighting and outlets. Ensure outdoor outlets are GFCI-protected and fixtures are weather-rated.
9. Furniture & Storage: Anchor tall items and avoid cluttered pathways. Heavy planters or waterlogged storage boxes can cause structural stress.
10. Surroundings: Watch for tree limbs that may fall or debris that could clog drainage. Make sure water isn’t pooling under your deck.

Why Building Codes Matter

Many deck failures happen because they don’t meet modern building codes. Key requirements from the International Residential Code (IRC) include:

• Secure Connections: Use bolts or lag screws—not nails—for attaching ledger boards to the home.
• Load Capacity: Residential decks must support a minimum of 40 pounds per square foot.
• Railing Height & Spacing: Railings should be at least 36 inches tall, and baluster spacing must not exceed 4 inches.
• GFCI Electrical Protection: Required for all outdoor outlets to prevent shock.
• Flashing Requirements: Metal flashing is essential at the ledger board to prevent water infiltration into the home’s frame.

Even if your deck predates these rules, it’s smart to retrofit or upgrade to today’s standards. Not only does it protect your family—it can increase your property value and make it easier to sell down the road.

Routine Maintenance Tips

A safe deck isn’t just about structure—it’s about upkeep. Here’s how to protect yours all year round:

• Clean It Regularly: Sweep off leaves and dirt, and wash the surface with a mild cleaner or oxygen bleach to remove grime. Pressure washing can work well but avoid overdoing it to prevent splintering.
• Seal or Stain Annually: Apply a water-repellent stain or sealer every year (or as needed). This prevents moisture damage and protects against UV rays.
• Check Hardware: Tighten bolts, screws, and connectors. Replace corroded metal parts with galvanized or stainless steel alternatives.
• Inspect After Storms: High winds and heavy rain can shift furniture, pull out nails, or dislodge parts of the railing. Give everything a post-storm once-over.
• Maintain Furniture & Decor: Periodically clean cushions and outdoor rugs, and store them when not in use to avoid trapping moisture that can rot wood underneath.

When to Call a Pro

DIY is great, but some issues are better left to a licensed contractor or certified inspector. Call a professional if:

• Your deck is over 15 years old and hasn’t had a formal inspection.
• You notice major issues like leaning posts, pulling ledger boards, or cracked joists.
• You’re planning to install a hot tub, extend the platform, or increase the load.
• You need help meeting local building codes or pulling permits for large upgrades.

Final Thoughts

Your deck is more than wood and nails—it’s where family and friends gather, memories are made, and comfort meets the outdoors. But without proper care, it can quickly become a hazard. National Deck Safety Month is your reminder to stop, inspect, and protect your space before a fun afternoon turns into a costly mistake.

By investing a little time and effort each year, you’ll enjoy your deck worry-free—and it’ll serve your home well for years to come.
