    One of the most challenging parts of designing outdoor space is selecting the suitable deck material, amongst several options, such as wood, composite material, and laminates. Investing in the best deck is worth the time, money, and energy as it adds visual appeal and ensures longevity.

    Out of multiple deck material options, composite decking is the best choice due to its durability (it is a blend of recycled wood fibers and plastic) and capability to withstand the elements along with other qualities. The best feature is its prolonged durability of 25-30 years or more. If you are in search of an answer to "How Long Does Composite Decking Last?", read the article to know more about it.

    Why is Composite Decking Preferred Over Other Deck Material?

    The composition of the composite decking makes it a preferred choice. It is made with a mixture of recycled wood and plastic, which is layered with a sturdy plastic shield, giving it strength and durability.

    Some of the other features that raise the demand for composite decking over wood and other materials are as follows:

    Longevity

    It handles the exposure to the elements and prolonged exposure to sun and UV rays, can withstand extreme weather conditions (hot, cold, snow, and rain), and doesn't splinter, warp, crack, or rot after a cycle of freeze and thaw. It can last between 15-25 years and more.

    Easy Maintenance

    Wood composite decking, a star of outdoor spaces, demands surprisingly little upkeep. Unlike traditional wood decks, which require regular sanding and staining, this modern alternative saves you plenty of time and effort. It's resistant to fading, scratching, and even the harshest weather conditions, leaving you more time to enjoy your outdoor oasis rather than work on it.

    The durability of the composite material ensures easy upkeep. All you have to do is clean it with soap and water or gently pressure clean it twice a year.

    Resistance to Water and Moisture

    Composite decking is more resistant to water and moisture because it is made with compress technology that creates a strong bond between the cap and core. There's no need to worry about moisture infiltration and sealant.

    Resistance to Termites

    Composite decking is termite resistant because termites won't get cellulose to eat, unlike wood decking.

    Resistance to Mold and Rot

    Mold can't grow on the composite decking surface, avoiding rotting, so there's no chance of any damage to the deck, adding more life to it.

    No Discoloration

    The durability of the composite decking keeps it structurally sound, which saves it from discoloration and fading. The color in the composite deck goes through the board, so it won't chip off. The fact is that all the manufacturers give color warranties to their buyers.

    Saves Time and Money

    Low maintenance and durability of the composite material save you time, energy, and money. These decks are cleaned merely with mild soap and water, requiring minimal cost and less time.

    Environment-Friendly

    It is an eco-friendly material because it is made with recycled material using earth-friendly processes. No chemical is used in the manufacturing of composite materials.

    Extended Warranty Period

    Most of the manufacturers give an extended warranty of 25-50 years on their products and an additional warranty of 25 years on stains and fading. The manufacturers are able to give such warranties because of the process and the material used to manufacture composite decking.

    The composite decking lasts between 15-25 years or even more. It ages like wine and looks great even after many years. It's difficult to believe that it can last for even 40 years, but it has a proven track record of many years of its lifespan. The reason is composite decking is made from recycled plastics that protect it from wear and tear, unlike traditional timber decking, which is prone to warp, rot, and splitting.

    Ways to Keep Your Composite Decking Longer

    Regular Maintenance

    Wipe the deck every one or two weeks to clean dust and debris and clean it with water as and when required. Scrub the deck with a broom using warm water and floor cleaner for thorough cleaning at least once a year.

    Don't Use Harsh Chemicals

    Avoid using cleaners with harsh chemicals for deck cleaning because it may harm the protective coating of the deck material. A mild soap is sufficient to clean it.

    Avoid Using Salt and Sand to Deal With Ice

    Though ice is a rare occurrence, it's good to know about it. Don't use salt and sand to deal with ice because they can damage the deck with frequent use.

    Avoid Scratches

    Avoid dragging heavy furniture around the composite deck to protect it from scratches. Some of the other reasons affecting the visual appeal of the deck are pets and changing the place of furniture, which leaves marks on the deck's surface. It won't affect the longevity of the deck, but the aesthetic.

    Conclusion

    Multiple features of composite decking ensure a long life, helping you spend more time with your friends and family and less time painting decks, fixing nails, replacing warped boards, and sanding.
