Benefits of Composite Decking

One of the biggest advantages of composite decking is its low-maintenance nature—no need for yearly bleaching, staining, or sealing like traditional wood decks. A quick rinse with a garden hose once or twice a year is all it takes to keep your deck looking great.

Built for long-lasting durability, composite decking resists fading, splintering, and rotting while being completely insect-proof. Unlike wood, composite boards can be manufactured in longer lengths, reducing seams and simplifying installation for a cleaner, more seamless look.

Frequently asked questions

How long does composite decking last?

The lifespan of composite decking varies by brand, but high-quality options like Trex can last 25 to 30 years with minimal maintenance. While composite decking may have a higher upfront cost compared to pine or other wood options, its exceptional durability, resistance to rot, and low maintenance requirements make it a cost-effective, long-term investment. With no need for staining, sealing, or frequent repairs, composite decking offers lasting beauty and value for your outdoor space

What is Composite Decking made of?

Composite decking is an eco-friendly choice, crafted from recycled or reclaimed plastics combined with wood fibers, bamboo fillers, PVC, and other durable materials. By repurposing these materials, composite decking reduces landfill waste and minimizes environmental impact, making it a sustainable alternative to traditional wood decking. Enjoy a beautiful, long-lasting deck while contributing to a greener planet!

How do I clean Composite Decking?

Keeping your composite deck clean is simple and requires minimal effort—just once or twice a year! To maintain its beauty and longevity, follow these easy steps:

  1. Rinse the deck with a garden hose to remove surface debris like leaves, pollen, and dirt.

  2. Scrub gently using a soft-bristle outdoor broom and a mild soap-and-water solution to lift any stubborn grime.

  3. Rinse thoroughly to remove any soapy residue, then let your deck air dry.

With no need for staining, sealing, or sanding, composite decking offers a hassle-free, low-maintenance solution for a pristine outdoor space all year round.
