Year-End Deck Maintenance Checklist: Essential Deck Care for Denver Homeowners

As the year comes to a close, it’s crucial to prepare your deck for the winter months and ensure it remains in good condition for the next year. Denver’s weather, with its mix of snowfall, freezing temperatures, and occasional sun, can take a toll on your deck if it’s not properly maintained. Performing year-end maintenance can prevent costly damage, prolong the life of your deck, and ensure it’s ready to use when warmer weather returns.

At Centennial Custom Decks, we specialize in helping homeowners care for their custom decks year-round. Here’s a comprehensive year-end deck maintenance checklist to keep your deck in top shape through the winter and beyond.

Clean Your Deck Thoroughly

Before winter sets in, a deep clean is essential to remove debris, dirt, and buildup that can cause long-term damage. Moisture, especially when combined with dirt and leaves, can lead to mold, mildew, and rot during Denver’s snowy season. By cleaning your deck thoroughly, you prevent these issues and maintain its appearance.

Sweep away leaves, dirt, and debris. Regularly sweep your deck, especially after fall when leaves and twigs tend to collect. This prevents them from decomposing and causing stains or trapping moisture against the deck’s surface.

Power wash or scrub the deck. Use a deck cleaner or a mixture of mild soap and water to scrub your deck. For tougher stains, especially if your deck has mold or mildew, use a cleaning solution designed for decks. If using a power washer, set it to a lower pressure to avoid damaging the wood or composite materials.

Inspect for mildew. Pay special attention to areas that receive less sunlight, as they’re more likely to develop mildew. If you spot any, treat the area with a deck cleaner or a solution of water and oxygen bleach.

Thorough cleaning sets the foundation for the rest of your year-end maintenance, ensuring your deck is ready for the winter months.

Inspect for Damage or Wear

After cleaning, take the time to inspect your deck for any signs of damage or wear. Catching issues early prevents small problems from becoming major repairs later on, especially as Denver’s winter conditions can exacerbate existing damage.

Look for loose or damaged boards that may need to be repaired or replaced. Tighten screws or nails that have popped up over time, as loose fasteners can be dangerous, especially with snow or ice present.

Cracks or splits in the wood are another concern, especially with wooden decks. Cold temperatures can worsen these cracks, so be sure to seal them with a wood filler or sealant to prevent further damage from moisture.

Examine the deck for any signs of rotting or decayed wood, which appears as soft spots or discoloration. This is especially important for untreated wood. Any rotting boards should be replaced immediately to prevent structural issues.

Inspect railings and stairs for safety. Make sure everything is secure and free of damage, tightening any loose bolts or screws and replacing weakened or damaged railings.

Protect Your Deck with a Sealant or Stain

Denver’s winters, with their freezing temperatures and heavy snowfall, can cause significant wear and tear on an unprotected deck. Applying a high-quality sealant or stain is essential for shielding your deck from moisture, snow, and ice. Sealing your deck helps prevent water from penetrating the wood, which can lead to warping, cracking, and rotting.

Start by choosing the right product for your deck material. Wood decks benefit from a weatherproof sealant that protects against moisture while also providing UV protection. Composite decks may require less maintenance but can still benefit from a protective layer to guard against stains and fading.

Make sure your deck is completely dry before applying the sealant or stain. Fall in Denver often brings unpredictable weather, so plan to apply the product during a stretch of dry, mild days. Focus on applying an even coat, paying special attention to cracks, joints, and end grains where moisture tends to accumulate.

A properly sealed deck will not only look better but will also last longer and be more resistant to the harsh winter elements.

Clear Furniture and Accessories

One often overlooked aspect of year-end deck maintenance is clearing away outdoor furniture, planters, and other accessories. Leaving these items on your deck through the winter can lead to discoloration, trapped moisture, and surface damage, especially after snow and ice accumulate.

Store lightweight furniture, cushions, and outdoor rugs indoors or in a sheltered area to prevent them from being damaged by winter weather. For heavier furniture that remains outdoors, such as metal or stone tables, use weatherproof covers to protect them from the elements.

Also, consider removing any decorative items, such as planters, lanterns, or bird feeders, as these can trap moisture beneath them, leading to mold or mildew growth on the deck surface. If you have permanent features like built-in benches or pergolas, ensure they are clean and properly covered where necessary to prevent damage.

Taking the time to clear your deck of accessories ensures that your deck’s surface remains protected and helps you avoid unnecessary wear or damage.

Ensure Proper Drainage

As part of your year-end maintenance, it’s important to ensure that your deck has proper drainage to prevent water buildup during snowmelt. Pooling water can seep into the wood, leading to rot and other moisture-related damage over time.

Inspect your deck for areas where water tends to collect, such as around the posts or near the house. If you notice standing water, consider making adjustments to improve drainage. This may include adding a slight slope to the deck surface to allow water to flow off naturally or installing gutter systems to direct water away from the deck.

Clearing gutters and downspouts that are connected to the deck or the area surrounding it is also essential. Clogged gutters can cause water to overflow onto the deck, which can lead to water damage and ice formation.

By ensuring your deck has proper drainage, you can reduce the risk of moisture-related damage during Denver’s freeze-thaw cycles.

Perform Regular Winter Maintenance

While year-end maintenance sets the stage for a well-protected deck, regular upkeep throughout the winter is just as important. Heavy snowfall, ice, and fluctuating temperatures can cause wear and damage if left unchecked, so plan for regular maintenance during the colder months.

Clear snow and ice from your deck regularly. Use a plastic snow shovel rather than a metal one to avoid scratching the deck surface, and shovel in the direction of the deck boards to minimize damage. Avoid using traditional rock salt, as it can be harsh on wood and composite decking materials. Instead, opt for a deck-safe ice melt, such as one made from calcium chloride, to prevent slips and falls without causing damage.

Inspect your deck periodically throughout the winter for signs of damage, such as cracking, warping, or rotting. Address any issues immediately to prevent them from worsening under the harsh winter conditions.

By following these simple steps, you’ll keep your deck safe and in good condition until spring.
