Regular power washing can help remove dirt, grime, and other buildups that can damage the wood. By keeping your deck clean and free of debris, you can help to ensure that it will last for years to come. So next time you think about deck maintenance, remember to give it a good power wash.

2. Protect your deck from the elements

Composite decks are durable, but they can still be susceptible to damage from the wind and rain. Covering your deck when bad weather is forecast can help protect it from the elements and keep it looking good longer. So next time you’re expecting a storm, be sure to take some time to cover your deck. Otherwise, your deck might not make it through the season.

3. Keep your deck clean clean

In addition to power washing, sweep your deck regularly to remove dirt, leaves, and other debris. If you have trees nearby, you may also want to hose off your deck occasionally. This will prevent sap or bird droppings from staining the surface.

3. Keep your deck clean clean

When cleaning your deck, be sure to use a gentle cleanser and a soft brush to avoid damaging the wood. So your deck will look good and last longer.

4. Be careful with furniture over deck

If you’re not careful with your furniture, you could end up doing serious damage to your composite deck. Composite decks are a mixture of wood and plastic, making them long-lasting and easy to care for.


However, they can be scratched or damaged by heavy furniture. So before you drag that chair across the deck, think about how you can protect your investment.

5. Don’t use harsh chemicals to clean your deck

If your deck is made of composite materials, you might inadvertently damage it whenever you reach for the hose. That’s because many composite decks are sensitive to harsh chemicals, including those in some household cleaners. Harsh chemicals are more acidic in nature and will break down the composition of the deck, leading to costly repairs down the road.

When these chemicals come into contact with the surface of a composite deck, they can break down the material, causing it to become discolored and dingy. Over time, this damage can shorten the lifespan of your deck and make it more difficult to maintain.

So next time you reach for the hose, think twice about using harsh chemicals on your composite deck. Your deck will thank you for that.

6. Fix any damage to your deck

While composite decks are tough, they’re not invincible. If you notice any damage, such as cracks, splits, or loose boards, take care of it immediately. This will help you prevent further damage and extend the life of your deck.

7. Store materials properly

If you’re storing any materials on your deck (lumber, grilling supplies, etc.), be sure to keep them off the ground and away from the edge of the deck. This will prevent them from scratching or damaging the surface of your deck.

8. Don’t let it grow mold or mildew

Don’t let mold or mildew ruin your composite deck. Taking a few simple steps to prevent and remove mold will extend the life of your deck and make it look great for years to come. Composite decks are still susceptible to mold and mildew growth, especially in humid climates.

Mold and mildew not only damage the appearance of your deck but can also lead to premature decay. To prevent mold and mildew growth on your composite deck, sweep the deck regularly to remove debris, dirt, and leaves.

If you live in a humid climate, consider installing a dehumidifier to keep the air dry. If mold or mildew grows on your deck, don’t worry. There are plenty of effective cleaners on the market that will safely remove mold and mildew without damaging your deck.

With a little care and attention, you can keep your composite deck looking new for years to come.

9. Protect your deck from the sun

When sunlight directly hits composite decking, it causes the material to heat up. This can cause the color of your deck to fade over time.

To protect your deck from the sun, add shade with an umbrella or pergola. This will help keep your deck cooler and prevent the color from fading. If you don’t have space for a shade structure, you can try adding some plants to the area around your deck. This will provide natural shade and can make your deck more comfortable to spend time on.
