How Long Does Composite Decking Last?

Composite decking has become a popular alternative to traditional wood due to its low maintenance and long lifespan. Made from a blend of wood fibers and plastic, composite decking is designed to withstand the elements and resist issues like rot, splintering, and insect damage.

But how long does it really last, and what kind of warranty can you expect from top brands like Trex, TimberTech, and Deckorators?

The Lifespan of Composite Decking

When properly installed and maintained, composite decking can last 25 to 50 years or more, far exceeding the lifespan of traditional pressure treated wood decking, which typically requires replacement every 10-15 years. Factors such as climate, exposure to sunlight, and how well the deck is maintained will influence how long it lasts, but composite decking’s durability and resistance to weathering give it a clear advantage over natural wood.
