Top 5 Signs Your Deck Needs Repair or Replacement in Spokane, WA
Top 5 Signs Your Deck Needs Repair or Replacement in Spokane, WA
Most decks last between 10–20 years, depending on how well they were built and maintained. With Spokane’s seasonal weather—including heavy snow, rain, and strong summer sun—decks in Spokane, WA can experience significant wear over time.
If your deck is more than 10 years old, regular inspections are important to ensure it remains safe. Below is a checklist homeowners in Spokane and surrounding areas can use to determine whether a deck needs repair or replacement.
1. Decaying Wood
The condition of the structural components of your deck—such as the ledger board, joists, beams, and posts—is crucial to the strength and longevity of the structure.
Common signs of wood decay include:
- Dark spots or discoloration
- Mushy or spongy sections
- A musty smell underneath the deck
Spokane’s moisture from snow and rain can accelerate wood rot, especially on older decks. If you notice any of these issues, it may be time to start planning a repair or replacement.

2. Loose or Worn Railings
Deck railings are a critical safety feature. If your railings feel loose or unstable, it may indicate that other parts of your deck are also deteriorating.
Sometimes the solution is simple, such as tightening or adding fasteners to strengthen the posts. However, it’s important to check the condition of the railing posts themselves—especially if they are wooden or appear to be leaning out of plumb.
3. Sagging or Uneven Decking
Sagging or uneven decking often signals structural problems. In some cases, the issue may be caused by footings that were installed too shallow or undersized.
With Spokane’s freeze-thaw cycles, poorly installed footings can shift or sink over time, causing the deck to become uneven. If you notice sagging areas, the problem should be addressed quickly to prevent further structural damage.
A professional deck contractor can inspect the deck and determine whether repairs or new footings are needed.
4. Cracked or Splintered Deck Boards
Deck boards are exposed to constant weather conditions such as UV rays, rain, snow, and temperature swings. Because of this exposure, deck boards often wear out faster than the structural components.
Cracked, splintered, or heavily weathered boards are a common sign that your deck may need repairs or resurfacing.

5. Rusted or Popped-Out Fasteners
Rusted or popped-out fasteners can compromise the safety of your entire deck. Fasteners hold the structure together, and if they fail, the deck may weaken prematurely.
Signs to watch for include:
- Rusty streaks on joists, posts, beams, or the ledger board
- Rusted brackets or connectors
- Nails or screws backing out of the wood
Spokane’s moisture and seasonal weather can accelerate fastener corrosion over time.
