Winter Deck Maintenance
Harsh snowstorms and ice buildup can cause your once-beautiful deck to suffer from wear and tear and lead to long-term damage if not addressed. You've invested in your outdoor living space, and it's frustrating when it no longer functions as it once did. We understand these winter woes. Read on to learn how to prepare a deck for winter.
Preparing and Protecting Your Deck for Winter
Getting your deck ready for winter can prevent long-term damage. A little preparation now can save you a lot of headaches later. Here's how to winterize your deck:
Inspect Your Deck
Check your deck for any loose nails, screws or signs of damage. Once identified, tighten loose screws or nails, address cracks or splinters in the wood and ensure railings are secure.
Improve Drainage and Ventilation and Remove Debris
Promoting proper drainage and ventilation while keeping the surface clear of dirt, leaves and debris go hand in hand because buildup can obstruct water and airflow. Sweep away leaves and dirt from the surface of your deck and clean out any gaps between boards. Remember to trim overhanging branches to prevent more leaves from falling on your deck throughout winter.
If your deck is built close to the ground, make sure the area beneath is debris-free to prevent mold and mildew growth. Additionally, confirm that any built-in drainage outlets function properly and aren't clogged.
Move Furniture and Potting Plants Indoor
Water can pool under the furniture legs or plant pots, leading to moisture buildup. Bringing these items indoors protects them from the harsh winter elements and prevents damage to the wood. If moving large furniture isn't an option, place protective mats or covers under and over them.
Wash the Deck
Giving your deck one final wash before winter can help remove grime and dirt that might otherwise settle into the wood fibers. Follow these steps to clean your deck:
- Clear the surface: Remove any furniture or potted plants.
- Sweep off loose dirt and debris: Use a soft broom to sweep away dirt. Make sure to get into the gaps between the boards to remove trapped materials.
- Choose your cleaning solution: Use a store-bought deck cleaner that's compatible with your deck material or make a simple and effective cleaner by mixing a cup of dishwashing liquid with 2 gallons of warm water.
- Scrub or pressure wash: For a more controlled and gentle cleaning, use a long-handled soft-bristled brush or deck scrubber to apply the cleaning solution. Scrub following the wood grain to avoid scratches. If you choose to pressure wash, use the lowest setting to avoid gouging the wood or removing any protective layers. Hold the nozzle about 6 inches from the surface and move it in long, smooth strokes.
- Rinse thoroughly: Rinse the deck with a garden hose or pressure washer on a gentle setting.
- Allow the deck to dry completely: Your deck needs to dry completely before you apply any sealant or cover it with a tarp.
Apply Sealant or Stain
Applying a sealant or stain prevents moisture from seeping into the wood and reduces the chances of an insect infestation. Ideally, you should do this step before the temperature drops too low. But if you're in a pinch, you can apply it as long as the temperature is above freezing.
Staining enhances the color of your deck while offering moisture protection. Sealants provide a clear protective layer that focuses on water repellency without altering the deck's appearance. If you want to maintain the natural look of the wood while protecting it from moisture, a sealant is the way to go. But if your goal is both aesthetics and protection, a stain might be a better option.
Regardless of your choice, use oil-based solutions because they seep deeper into the wood pores and offer superior protection against cracking, splitting and general wear and tear.
Add Protection for High-Traffic Areas
Winter conditions can wear down high-traffic areas on your deck more quickly. To protect these spots, lay down water-resistant mats or outdoor rugs. These provide an extra layer of protection against moisture, snow and ice while also helping prevent slipping.
Cover Your Deck With a Tarp
If your deck won't be used much during the winter months, cover it with a tarp. Ensure the tarp is secure but allows for airflow to prevent moisture from getting trapped underneath.
Deck Maintenance and Upkeep During the Winter
Ongoing winter deck maintenance ensures your outdoor space stays in good shape. Here are some winter deck care tips:
Avoid Using Salt
Ice on your deck can be dangerous, but avoid reaching for salt. Salt is corrosive and can cause the wood to dry out, crack or discolor. It can also damage metal components that hold the deck together. Look for de-icing products labeled safe for wood or your specific decking material.
Remove Snow Regularly
Snow left for extended periods can lead to warping and increased pressure on the deck's surface. It's best to remove snow regularly, especially after each heavy snowfall. Waiting until the snow melts naturally can make the deck slippery. When removing snow, use a plastic shovel instead of a metal one to avoid scratching or damaging the wood. Be gentle as you shovel and try to push the snow in the direction of the boards.
Inspect the Deck
Regular inspection throughout the season helps you catch problems before they worsen. Look for the following:
- Cracks or splits
- Spongy or soft wood
- Discoloration or dark spots
- Loose boards or nails
Keep It Clean
Even in winter, it's important to keep your deck clean. After shoveling snow, take a few minutes to brush away any remaining ice or debris. Regularly sweeping it will help prevent moisture traps.
5 Signs Your Deck Has Winter Damage
Despite proper upkeep, cold temperatures, snow and moisture can still take a toll on your deck. Here are some common indicators of winter damage:
1. Evidence of Insects
Check for small holes in the wood, frass (wood-like termite droppings) or visible insects like termites or carpenter ants. These pests are attracted to damp wood, and their presence may indicate that winter moisture has created a conducive environment for infestations. If you notice signs of infestation, it's best to contact a pest control professional for effective treatment.
2. Wood or Beam Rot
If areas of your deck feel soft or spongy underfoot, this is a clear sign of wood rot. You can test this by pressing on the wood with your foot — solid, healthy wood should feel firm. Look for discoloration, dark spots or a musty smell. Check the support beams because these are vulnerable to moisture accumulation. Rotting wood compromises the structural integrity of your deck and can pose safety hazards, so it's best to replace the affected boards or beams to prevent further deterioration.
3. Loose Railings
Inspect the railings for any wobbling or loose connections. If you can shake or move the railing with minimal effort, they may need tightening or replacement. Loose railing can pose a safety risk. if you notice this issue, you can often tighten the connections yourself.
4. Cracked Wood
Examine the wood for visible cracks or splinters, especially at the ends or along the grain. if the cracks are deep, they may compromise the board's strength. If the cracks are shallow, you may be able to fill them with a wood filler or sealant. However, deeper cracks might require replacement to prevent further damage.
5. Mold or Mildew
Mold and mildew can affect your deck's appearance, weaken the wood and pose health risks to individuals with allergies or respiratory issues. Inspect your deck for signs of infestation, which usually appear as black, gray or white spots on the surface. Use a mixture of water and dish soap and a soft brush to scrub away fungal growth. For tougher spots, use a specialized cleaner.
