What to Do in October to Prep Your Fence and Deck for Winter

As the leaves fall and the temperatures drop, October is the perfect time to prepare your fence and deck for winter. A little maintenance now can prevent costly damage later and help your outdoor spaces look great year-round.

Whether your fence is wood, vinyl, or chain link, and your deck is big or small, these simple steps will protect your investment through the cold months ahead.

1. Inspect for Damage and Wear

Before winter sets in, walk the perimeter of your yard and check your fence and deck for loose boards, nails, screws, or wobbly posts. Fall moisture and freeze-thaw cycles can worsen even small issues, so it’s best to fix them now.

👉 Pro tip: if your posts are leaning or soft at the base, it could be a sign of rot or poor drainage. MM Posthole Digging can help assess and secure those before frost hits.

2. Clean Away Dirt, Leaves, and Debris

Fallen leaves and damp debris can trap moisture and speed up rot or mildew growth. Sweep, blow, or rinse away buildup from your fence line and deck surface. For wood decks, a gentle scrub with deck cleaner helps lift grime before it sets in for winter.

3. Protect Wood with a Fresh Seal or Stain

October is your last chance to apply a weatherproof sealant or stain before cold temperatures arrive. A protective coating keeps out water and prevents cracking, warping, or splitting caused by freezing moisture.

Look for a product rated for Canadian winters for the best results.

4. Check Gates and Hardware

Cold weather can make metal components shrink or seize. Make sure hinges, latches, and screws are tightened and properly lubricated. A few minutes of care can save you from dealing with frozen gates in January!

5. Keep Snow and Ice at Bay

Once winter arrives, try to avoid piling snow directly against your fence or deck. The extra weight and moisture can weaken posts or boards. If you use de-icer near your deck, choose a pet- and plant-safe formula that won’t damage wood or metal.
