The Most Common Deck Problems in Winnipeg and How to Fix Them

1. Rotting or Decaying Wood

Cause: Winnipeg’s harsh winters and spring thawing can cause moisture buildup on your deck, leading to rot and decay.

Fix:

• Replace any rotted boards with fresh, durable wood.
• Apply a waterproof sealant or stain to prevent further moisture damage and keep your deck looking great.

Pro Tip: Regularly inspect the underside of your deck for moisture accumulation. This helps catch issues before they spread.

2. Wobbly Railings or Loose Fasteners

Cause: Over time, screws and fasteners can loosen due to temperature fluctuations and the shifting foundation beneath your deck.

Fix:

• Tighten all loose screws and bolts in your railings.
• Reinforce with new, sturdier bolts if necessary for added security.

Pro Tip: Prevent future issues by using corrosion-resistant fasteners, especially in areas exposed to moisture.

3. Cracked or Warped Boards

Cause: Winnipeg’s significant temperature changes—from freezing winters to hot summers—can cause wood to expand and contract, leading to cracks and warping.
Fix:

• Replace any damaged boards to restore the deck’s integrity.
• Use a UV-resistant stain to prevent sun damage and fading, helping to maintain the boards’ strength.

Pro Tip: Choose composite or PVC decking if you’re looking for a material that resists warping over time.

4. Sinking or Uneven Deck Structure

Cause: If the footings were not installed properly or the soil shifts over time, your deck may start to sink or become uneven.

Fix:

• Relevel the deck by adjusting the foundation and supports.
• Reinforce the footings to ensure the deck stays level.

Pro Tip: Consider using concrete or gravel footings for added stability.

5. Mold, Mildew, and Slippery Surfaces

Cause: High humidity, lack of sunlight, and poor drainage can lead to mold and mildew growth on your deck, creating slippery surfaces.

Fix:

• Power wash your deck regularly to remove dirt, algae, and mold.
• Apply an anti-slip treatment to prevent accidents and keep the deck safe to walk on.

Pro Tip: Regular cleaning and ensuring proper drainage will help prevent mold growth.
