How to Care for Decks in the Snow and Cold

Decks are probably one of the least used parts of your house during the winter. So why are we talking about them in this month’s article? Well, although you may not be using it as much over the next few months, it doesn’t mean that decks aren’t a valuable extension of your home, especially if we recently repaired or replaced yours. They provide a comfortable space to relax and entertain. However, winter weather—especially snow, ice, and freezing temperatures—can take a toll on your deck’s structure and appearance. Proper care and maintenance during the colder months are crucial to protect your investment and ensure your deck remains in great condition when warmer weather returns. Here are some tips from your friends at Innovative Builders on how to care for your deck in the snow and cold.

Keep Your Deck Clear of Snow and Ice

Allowing snow and ice to accumulate on your deck can lead to excess moisture exposure, which may cause warping, cracking, or mildew growth. To prevent these issues:

• Shovel regularly: Use a plastic shovel rather than a metal one to avoid scratching or damaging the deck boards. Always shovel in the direction of the boards to prevent gouging.
• Avoid heavy snow buildup: If snow piles up, remove it in layers instead of trying to clear it all at once to prevent strain on the deck.
• Sweep light snowfalls: A broom can be effective for removing light snow accumulations before they turn to ice.

Use the Right Ice Melt Products

While it’s important to keep your deck ice-free for safety, some de-icing products can be harmful to wood, composite materials, and hardware:

• Avoid rock salt: Traditional rock salt can cause corrosion and discoloration on your deck and fasteners.
• Opt for calcium chloride: This is a safer alternative for wood and composite decks, as it melts ice effectively without causing damage.
• Check manufacturer recommendations: If you have a composite or PVC deck, refer to the manufacturer's guidelines for approved ice melt products.
• Use sand for traction: If you're concerned about using chemical de-icers, applying sand can provide grip without causing damage.

Protect Your Deck from Moisture Damage

Winter moisture can seep into the deck’s wood, causing it to expand and contract with freezing temperatures. This can lead to cracks, splinters, and rot over time:

• Apply a water-repellent sealant: Before winter hits, apply a high-quality sealant to protect your deck from moisture penetration.
• Check for standing water: Inspect the deck after snow melts to ensure water isn't pooling, which could lead to damage if it refreezes.
• Install proper drainage: Make sure gutters and downspouts are directing water away from the deck to prevent constant exposure to moisture.

Inspect and Repair Before Winter Hits

Preventive maintenance before winter begins can help you avoid costly repairs in the spring:

• Check for loose boards or fasteners: Ensure everything is secure to prevent further damage from expanding and contracting due to temperature fluctuations.
• Inspect for rot or mold: Address any signs of decay before they worsen in the damp winter months.
• Re-stain or reseal if necessary: If your deck’s finish is looking worn, applying a fresh coat of stain or sealant before winter can add an extra layer of protection.

Be Cautious with Winter Furniture and Decor

Heavy winter decorations, furniture, and grills can put unnecessary stress on your deck during the colder months:

• Store furniture indoors: If possible, store furniture, planters, and other large items to prevent them from trapping moisture against the deck surface.
• Use protective pads: Place pads under heavy furniture that remains outside to avoid scratching or damaging the deck surface.
• Lift furniture instead of dragging: When repositioning items, lift them to avoid scraping the deck boards.

Regular Winter Inspections

Regularly checking your deck during winter can help you catch potential issues early:

• Look for signs of mold or mildew: Even in colder weather, mold and mildew can develop in moist areas.
• Check for cracks or splinters: Address minor damage before it worsens due to the freeze-thaw cycle.
• Monitor structural integrity: Pay attention to any sagging or bending that might indicate deeper structural problems.

Plan for Spring Maintenance

Taking care of your deck during winter will make spring cleanup easier and extend the life of your deck:

• Schedule a deep cleaning: Plan to wash and reseal your deck in early spring to restore its appearance and protection.
• Inspect for winter damage: Evaluate your deck for any issues caused by snow and ice and address them promptly.
• Consider upgrades: If your deck needs refinishing or repairs, spring is the perfect time to take on those projects.
