Is Your St. Louis Deck Safe? St. Louis Deck Safety Checklist

Collapsed stairs in St. Louis Missouri

As a St. Louis homeowner, you need a beautiful outdoor living space that is both functional and structurally sound enough to handle Missouri’s intense freeze-thaw cycles. Because the wear and tear from shifting soil can sneak up on anyone, this seasonal rush is backed by an annual nationwide awareness campaign known as Deck Safety Month [NADRA’s Deck Safety Initiative].

What Is Deck Safety Month?

Deck experts have estimated that over 60 million decks are installed each year and 30 million of those decks are past their useful lifespans. Specifically, these 30 million decks need repairs or total replacement. To counter the rise in preventable deck failures and collapses, the North American Deck and Railing Association (NADRA) established May as deck safety month.

Additionally, after recognizing that millions of aging decks were built before modern, strict building codes were put in place, the NADRA launched this annual public awareness campaign right before peak summer gathering season. Furthermore, the initiative serves as an essential role in public safety by educating homeowners on hidden dangers and providing detailed tools for inspection.

  • Loose or corroded fasteners
  • Outdoor furniture and storage
  • Railings and banisters

How Do I Inspect My Deck for Safety? Your Complete Home Checklist:

As expert deck installers, we recommend contacting one of our professionals at Chesterfield Fence and Deck to guarantee your deck is safe and up to code. However, every homeowner should be aware of any deck safety hazards to prevent deck injuries.

To do your own at-home deck inspection, use the following comprehensive deck safety checklist to inspect your outdoor space.

Split or decaying wood
  • Identify any areas that look concerning to ask our deck experts about.
  • Pay attention to areas that are frequently exposed to water.
  • Check for small holes that could indicate insect infestation.
Loose or corroded fasteners
  • Look for any loose fasteners.
  • If a fastener looks rusted, consider replacement.
    • A corroded fastener can cause deterioration in surrounding wood.
  • Your deck or stairs should not sway or sag.
Outdoor furniture and storage
  • Ensure all furniture is sturdy.
  • Avoid placing seating near the edge of your deck.
  • Consider adding childproof latches to storage containers or benches.
Railings and banisters
  • Ensure all railings and banisters are secure in place.
    • If there is anything loose, call a Chesterfield Fence and Deck expert!
Lighting and Electrical
  • Consider adding lighting to your deck to illuminate the steps and pathways.
  • Make sure all lights are operational.
  • Clean off any lighting to ensure maximum efficiency.
  • Ensure all outlets are up to code and childproof, if needed.
Surrounding trees
  • Trim any overhang so there is no possible danger of tree limbs falling on your deck.
Fire Features
  • Move all fire features away from anything flammable.
  • Utilize non-flammable mats underneath fire features.
Cleanliness
  • Clean off any leaves or debris since they can make your deck slick and support mildew.
    • For mildew, ensure its cleaned off, and you apply a new waterproof coating.
Flashing (installed between the deck and house)
  • Look for any water damage, and call a Chesterfield Fence and Deck expert if you’re unsure.
Stairs
  • Check that any railings or handrails are firmly in place.
  • Keep stair pathways clear of anything that could be a tripping hazard.

Ultimately, the best way to enjoy your outdoor living space is by ensuring you check everything off this ultimate deck safety checklist and call a Chesterfield Fence and Deck expert for all your decking needs.

How Often Should a Homeowner Schedule a Professional Deck Inspection?

According to the NADRA, homeowners should visually inspect their outdoor structures every spring, but a professional deck inspection should be scheduled at least once every three years.

An annual professional assessment is highly recommended by St. Louis deck experts, for structures exceeding 10 to 15 years of age, or properties exposed to harsh seasonal weather.

Why should I get a professional deck inspection?

Professional inspectors look beyond superficial cosmetic wear to evaluate the hidden structural integrity of the deck.

  • They scrutinize critical load-bearing components.
  • They find hidden wood rot or rusted fasteners that a standard visual DIY check might easily miss.

Additionally, this routine schedule is especially critical due to the extreme St. Louis regional weather. In Missouri, decks endure severe winter freeze-thaw cycles, where melted snow seeps deep into porous wood fibers during the day and freezes overnight.

This relentless cycle can cause rapid deck expansion, contraction, splintering, and cracking. Furthermore, St. Louis winters are immediately followed by heavy spring rains and intense summer humidity. This creates a perfect breeding ground for moisture entrapment and aggressive wood rot along unsealed joists.

Over time, these local climate fluctuations warp boards and loosen vital specially coated fasteners, making professional deck inspections necessary to catch structural failures early.
