Deck Safety Inspection Checklist: What Seattle Homeowners Should Look for Before Winter Weather

Don’t Let Winter Weather Catch Your Seattle Deck Off Guard – Here’s Your Essential Safety Inspection Checklist

As Seattle homeowners prepare for another wet winter season, your deck faces months of challenging Pacific Northwest weather conditions. Decks are exposed to harsh weather year-round, from scorching summers to freezing winters, which can weaken their structural integrity over time. The North American Deck and Railing Association (NADRA) estimates there are over 60 million decks in the U.S., with approximately 30 million past their useful life, posing significant safety risks. Before the rain, snow, and freezing temperatures arrive, conducting a thorough safety inspection could save you from costly repairs and dangerous accidents.

Why Pre-Winter Deck Inspections Are Critical

Decks are popular outdoor spaces for relaxation and entertainment, but they require regular maintenance to remain safe. According to the Consumer Product Safety Commission (CPSC), hundreds of people are injured each year because of structural failures or collapses of decks, porches, and balconies. In Seattle’s climate, the wet season can wreak havoc on lumber in Seattle, including your deck, garden structures, and wooden patio furniture. Take the time to waterproof these items and seal them now, so they can withstand the onslaught of rain this fall and winter season.

Addressing these issues now can prevent further damage from freezing and thawing cycles throughout the winter months. If any of these signs of damage are visible, it’s important to fix them before the winter season arrives. Cold, wet, and snowy weather is highly likely to worsen the damage and decrease the life of your deck.

Essential Deck Safety Inspection Checklist

1. Examine the Deck Surface

Wood decking is highly susceptible to water damage and weathering. Splintering and cracks are inevitable, though you can improve your deck’s form and appearance with annual maintenance. Walk across your entire deck surface, looking for:

  • Loose, cracked, or rotting boards
  • Protruding nails or screws
  • Splintering or warping
  • Signs of weathering such as splintering, warping, or excessive fading

2. Test Railings and Balusters

Test guardrails by pushing against them. A 180-pound person should feel secure placing their weight against the railing with little to no movement. Check that:

  • Deck railings should meet local building codes for height and strength. Generally, railings should be at least 36 inches high and able to withstand significant lateral force.
  • All balusters are secure and properly spaced
  • No loose connections or deteriorating fasteners

3. Inspect Stairs and Handrails

The stairs leading up to a deck are often one of the most overlooked areas and pose one of the largest risks. Our company has inspected thousands of homes with decks and approximately 80% of deck stairs that we’ve inspected are not installed or maintained properly. Examine:

  • Stair tread stability and condition
  • Stairs with four or more risers should have a handrail on at least one side. Handrail height should be between 34 and 38 inches measured vertically from the sloped plane adjoining the tread nosing.
  • Secure attachment of stringers to the deck

4. Check Structural Components

The joists, rim boards, ledger boards, and blocking create a deck frame, which supports the deck’s surface, occupants, and furniture. Deck frames are typically wooden and vital to the safety and comfort of a deck, so it’s important to inspect for rot often. Look for:

  • Signs of rot or decay in support posts
  • Rotted wood feels soft and spongy, and may be dark or show cracks. Check for wood rot by prying a chunk of wood away with a screwdriver or other probe. If it splinters, the wood is healthy. If the break splits in chunks without splinters, it may be rotted.
  • Secure ledger board attachment to your home
  • Foundation and footing stability

5. Evaluate Flashing and Drainage

Flashing is a steel sheet installed over vital connections like the ledger board to prevent water and debris from reaching the wood. Flashing tape also prevents moisture damage and is easy to attach to wood joists. Ensure proper water management by checking:

  • Flashing around ledger boards
  • Proper deck slope for water runoff
  • Clear drainage between deck boards

When to Call Professionals

Lesh recommends having your deck professionally inspected every few years. “Your deck is in weather all year long, and there’s no protection. There’s no ‘check engine light’ on a deck,” he explains. Routine professional assessments can catch problems before they become serious, ensuring that your deck remains a safe place for relaxation and entertainment.

If you discover significant structural issues, extensive rot, or loose connections during your inspection, it’s time to contact a professional. Furthermore, it is highly recommended that any deck over 10 years old be inspected by a building professional with knowledge of current code. As building code evolves, new techniques and materials aimed at making sure decking projects are safe may need to be implemented.

Preparing Your Deck for Seattle’s Winter Weather

Once your inspection is complete and any necessary repairs are made, take these additional steps to protect your investment:

  • Applying a protective sealant or stain is a great way to safeguard your deck from winter weather. Traditional Wood Decks: Consider applying a waterproof sealant to protect the wood from moisture. This will help prevent water from seeping in and freezing, which can cause cracks or warping.
  • Clear all debris, leaves, and standing water
  • Remove or properly store outdoor furniture
  • Remove snow: Your driveway and sidewalk aren’t the only places that need to be snow-free this winter. When you’re outside shoveling, make sure you clear off your deck! To avoid ruining your paint or finish, brush the snow off in the same directions your boards run, and never lay down salt or a similar ice melter.
