Composite decking is often praised for its low-maintenance appeal compared to traditional wood, but does that mean it requires no upkeep at all? The answer is no. While composite decking certainly requires less work than wood, some maintenance is still necessary to keep your deck looking its best and performing well. Neglecting these tasks could not only affect the appearance and longevity of your deck but may also void the manufacturer’s warranty.
What Maintenance Does Composite Decking Require?
Unlike wood, composite decking doesn’t need to be sanded, stained, or sealed. However, regular cleaning is still important to prevent the buildup of dirt, grime, mold, and mildew. Here are some key maintenance tasks:
- Regular Cleaning: Manufacturers typically recommend cleaning your deck with a hose or power washer (on a low setting) to remove dirt, dust, and debris. It’s important to use a mild soap or a composite decking cleaner approved by the manufacturer to avoid damaging the boards. A soft brush can help clean crevices and remove stubborn stains.
- Removing Stains: Stains from food, drinks, and other materials should be cleaned as soon as possible. While composite decking is stain-resistant, prolonged exposure to certain substances can cause discoloration if not treated quickly.
- Mold and Mildew Prevention: Composite decking materials, especially those with a wood-plastic blend, can still harbor mold or mildew if water and debris are allowed to sit for long periods. Regular cleaning and ensuring proper drainage are key to preventing this issue.
- Snow and Ice Removal: In colder climates, it’s recommended to use a plastic shovel to remove snow. Avoid using metal shovels or sharp objects, as they can damage the surface of your decking. For ice, it’s best to use rock salt or a calcium chloride-based ice melt that’s safe for composite decking. Always check you manufacturers recommended ice removal products before applying them to your deck.
Why You Must Follow Manufacturer’s Maintenance Guidelines
Each composite decking brand provides specific instructions on how to care for their products. Following these guidelines is critical, not just for ensuring the longevity of your deck, but for maintaining your warranty coverage.
Not adhering to the manufacturer’s recommended maintenance schedule and techniques can void your warranty. Most composite decking brands offer warranties ranging from 20 to 50 years, covering issues like fading, staining, or structural failure. However, if you neglect to follow their care instructions—such as using the wrong cleaning agents or failing to remove debris and standing water—your warranty claim could be denied.
How Often Should You Perform Maintenance?
While composite decking requires less maintenance than traditional wood, it still benefits from routine care. A general rule of thumb is to clean your deck at least twice a year—typically in the spring and fall. You may need to do so more frequently if your deck is under trees or in an area with heavy foot traffic.
Conclusion
Composite decking offers significant advantages over traditional wood when it comes to maintenance, but that doesn’t mean it’s maintenance-free. Regular cleaning and following the manufacturer’s care instructions are essential to preserving the beauty and longevity of your deck. Remember, failing to follow these guidelines can void your warranty, costing you more in the long run. By investing a little time in proper maintenance, you can enjoy a stunning and functional composite deck for years to come.
