Composite decks are a popular choice for homeowners because they are durable, low-maintenance, and offer a beautiful, natural appearance. However, like any outdoor structure, composite decking requires some upkeep to ensure it stays in top condition. Regular maintenance will not only keep your deck looking great but also extend its lifespan. In this guide, we'll walk you through the essential steps to properly maintain a composite deck.
1. Regular Cleaning
One of the best ways to maintain a composite deck is to clean it regularly. Dirt, leaves, and debris can accumulate on the surface, which may cause staining or mold growth over time. To prevent this, sweep your deck regularly and wash it down with water. For a more thorough cleaning, use a mild soap and a soft-bristle brush to scrub the surface.
2. Avoid Harsh Chemicals
When cleaning your composite deck, avoid using harsh chemicals like bleach or ammonia, as they can damage the deck’s surface. Instead, stick to gentle, eco-friendly cleaning products designed for composite materials. These will effectively remove dirt and grime without causing harm to the decking material.
3. Remove Stains Promptly
While composite decks are resistant to many stains, it’s still important to clean up spills as soon as possible to prevent staining. This is especially true for food, grease, and oil spills. Use warm, soapy water and a soft cloth to clean the affected area. For tougher stains, a specialized composite deck cleaner may be required.
4. Prevent Mold and Mildew
Mold and mildew can grow on composite decks if moisture is trapped in shaded or covered areas. To prevent this, make sure your deck gets enough sunlight and airflow. You can also periodically wash your deck with a mold cleaner to prevent any growth. It's a good idea to remove leaves and organic debris regularly as they can hold moisture.
5. Check for Damage
Although composite decks are durable, they can still suffer from wear and tear over time. Periodically inspect your deck for any signs of damage, such as cracks, loose boards, or other structural issues. If you find any problems, repair them as soon as possible to prevent further damage.
6. Protect Against Heavy Furniture
Heavy outdoor furniture can cause dents or scratches on your composite deck. To avoid this, use protective pads under furniture legs or avoid dragging heavy objects across the surface. This will help prevent unnecessary damage and keep your deck looking new.
7. Power Washing – Use with Caution
While power washing can be an effective way to clean your deck, it should be done carefully. If the water pressure is too high, it can damage the surface of the composite decking. Use a power washer on a low setting (below 1,500 psi) and keep the nozzle at least 8-10 inches away from the surface to avoid any damage.
8. Maintain Proper Drainage
Composite decks can trap water if proper drainage isn't in place, leading to mold and mildew growth. Make sure that water flows off the deck freely and doesn’t pool in any areas. Clean out the gaps between the decking boards to ensure proper drainage and airflow.
9. Cover the Deck When Not in Use
To extend the life of your composite deck, consider using furniture covers or a deck cover when the deck is not in use, especially during winter or in extreme weather. This will help protect it from the elements, reducing the chances of damage from UV rays, rain, or snow.
10. Refinish or Seal – Not Always Necessary
Unlike wood decks, composite decks typically don’t need to be stained, sealed, or painted. However, if your deck starts to lose its color or shine over time, there are some refinishing products designed for composite materials. Consult with the manufacturer to find the appropriate product for your deck.
11. Avoid Metal Shovels in Winter
If you live in an area with snow, avoid using metal shovels to clear your deck. The metal can scratch or damage the surface of the composite material. Instead, use a plastic shovel or a broom to gently remove snow without causing harm to the deck.
12. Keep Plants and Trees Trimmed
If you have trees, plants, or bushes around your deck, keep them trimmed to prevent debris from accumulating on the surface. Overhanging branches can drop leaves and dirt onto the deck, leading to more frequent cleaning. Maintaining the surrounding landscape can help keep your deck cleaner for longer.
Maintaining a composite deck is relatively easy compared to traditional wood decks. With regular cleaning, inspection, and a few simple precautions, you can keep your composite deck looking beautiful for years to come. Whether you're preparing for summer or keeping it in top shape during the winter months, these tips will help ensure your deck stays in great condition.
