The Durability of Composite Decking: How Long Does It Last? 

As outdoor living spaces become more integral to home design, the demand for durable decking materials has risen. Composite decking stands out as a top choice, praised for its longevity and easy maintenance. Choosing the right material for your deck involves weighing several factors, with durability being one of the most important. In this blog, we look into the durability of composite decking, exploring how long it lasts and what homeowners can expect from this innovative material.

Ten Reasons Why Composite Decking Lasts Longer Than Wood

Composite decking has gained popularity for its durability and low maintenance, often outlasting traditional wood decking. Here are ten reasons why composite decking tends to last longer than wood:

1. Resistance to Rot and Decay

Composite decking is made from wood fibers and plastic, making it highly resistant to rot and decay. Unlike wood, which can break down over time due to moisture and fungal growth, composite materials remain intact.

2. Insect Resistance

Wood decks are vulnerable to damage from insects like termites and carpenter ants, which can compromise their structural integrity. Composite decking, on the other hand, is impervious to insect damage, ensuring a longer lifespan.

3. Moisture Resistance

Composite decking is water-resistant, preventing moisture from penetrating the material. This resistance lessens the possibility of swelling, cracking, and warping, common problems with wood decking exposed to the weather.

4. Low Maintenance Requirements

One of composite decking’s main benefits is its low maintenance. Unlike wood, which requires regular staining, sealing, and painting to protect against weathering, composite decking needs only periodic cleaning, saving time and effort and prolonging its life.

5. UV Resistance

Exposure to UV rays can cause wood to fade, crack, and splinter over time. UV inhibitors are frequently used in composite decking production to shield the material from sun damage and prolong its ability to maintain its structural integrity and color.

6. Consistent Quality

Wood decking can vary in quality, with knots, grain inconsistencies, and other imperfections affecting its durability. Composite decking is manufactured to consistent standards, ensuring uniform quality and performance, which contributes to its longevity.

7. Mold and Mildew Resistance

The organic nature of wood makes it susceptible to mold and mildew growth, especially in damp conditions. Composite decking is less prone to these issues due to its non-organic components, maintaining a cleaner, safer surface over time.

8. Splinter-Free Surface

Over time, wood decks can develop splinters, which can be a hazard, especially for barefoot traffic. Composite decking provides a smooth, splinter-free surface throughout its lifespan, enhancing safety and comfort.

9. Environmental Stability

Composite decking materials withstand various environmental conditions, from extreme heat to freezing temperatures. This stability helps prevent the material from expanding, contracting, or deteriorating, which can be a problem for wood decking.

10. Long-Term Warranty

Many composite decking manufacturers offer extended warranties, often up to 25-30 years, reflecting their confidence in the product’s durability. These warranties cover common issues such as fading, staining, and structural integrity, providing homeowners with peace of mind and underscoring the longevity of composite decking.

The Superior Longevity of Composite Decking

Compared to traditional wood decking, composite decking has many advantages, especially regarding longevity and durability. Its resistance to rot, insects, moisture, UV damage, low maintenance requirements, and consistent quality make it a superior choice for long-lasting outdoor spaces. Homeowners can enjoy a beautiful, durable, and worry-free deck for many years by investing in composite decking.

Installing Composite Decking

Composite decking has become popular among homeowners looking for a long-lasting, low-maintenance solution for their outdoor spaces. Installing composite decking can be a straightforward process, but it requires careful planning and attention to detail to ensure a successful and long-lasting result.

Planning and Preparation

Thorough planning and preparation are essential before beginning the installation process. Begin by measuring the area where you plan to install the decking. Accurate measurements will help you determine the amount of decking material needed and reduce waste. Ensure the ground is level and stable, and make any necessary adjustments to create a solid foundation.

Choosing the Right Materials

Selecting high-quality composite decking materials is essential for a successful installation. Consider the color, texture, and style best complement your home and landscape. In addition to the decking boards, you’ll need joists, fasteners, and any trim pieces required for your design. Many manufacturers offer matching components to create a cohesive look.

Preparing the Site

Begin by clearing the installation area of any debris, vegetation, or obstacles. If you’re installing an existing structure, ensure it’s in good condition and capable of supporting the new decking. Consider laying a weed barrier for ground-level installations to prevent unwanted growth beneath the deck.

Installing the Frame

The frame is the foundation of your decking, so it’s essential to build it correctly. Use pressure-treated lumber or metal for the joists, spaced according to the manufacturer’s recommendations, typically 12 to 16 inches apart. Secure the joists to the house and each other using appropriate fasteners. Ensure that the frame is square and level before proceeding.

Laying the Decking Boards

Begin laying the composite decking boards from the outer edge of the deck, working your way inward. Use hidden fasteners or screws designed for composite materials to secure the boards to the joists. Leave a small gap between each board to allow for expansion and drainage. Follow the manufacturer’s instructions regarding spacing and fastening to ensure optimal performance.

Finishing Touches

Once all the decking boards are in place, add any trim pieces or fascia to give the deck a finished appearance. Install railing systems, stairs, and other features according to your design plan. Finally, clean the deck to remove any dirt or debris from the installation process.

Achieving a Professional Finish

Installing composite decking requires careful planning, precise execution, and attention to detail. By following these steps and using high-quality materials, you can achieve a professional finish that will enhance the beauty and functionality of your outdoor space.

Composite Decking Maintenance

Composite decking is prized for its durability and low maintenance, but it still requires some care to keep it looking its best and to ensure its longevity. Regular maintenance can prevent minor issues from becoming major problems and keep your outdoor space attractive and functional. Here’s a comprehensive guide to maintaining your composite decking.

Regular Cleaning

Keeping your composite decking clean is essential to maintaining its appearance and preventing dirt, debris, and mildew buildup. Sweep the deck regularly to remove leaves, dirt, and other debris. Use a mild soap and water solution, a soft-bristle brush, or a pressure washer set to a low setting for a deeper clean. Avoid harsh chemicals or abrasive cleaners, as these can damage the surface of the decking.

Stain and Spot Removal

Despite its staining resistance, composite decking can still get occasional spots from food, drink, or organic matter. To remove stains, act quickly by blotting up spills with a soft cloth. Use a composite deck cleaner or a homemade solution of vinegar and baking soda for tougher stains. Apply the cleaner, let it sit for a few minutes, then scrub gently with a soft brush and rinse thoroughly.

Mold and Mildew Prevention

Composite decking is resistant to mold and mildew but is not entirely immune, especially in shaded or damp areas. To prevent mold and mildew growth, ensure good airflow around the deck by trimming plants and clearing debris. If mold or mildew does appear, clean it with a composite decking cleaner designed to tackle these issues.

Avoiding Scratches and Damage

While composite decking is more scratch-resistant than wood, taking precautions is still important to avoid damage. Place protective pads under furniture legs and avoid dragging heavy objects across the deck. If scratches do occur, they can often be minimized with a heat gun or by gently sanding the area, but be sure to follow the manufacturer’s recommendations.

Inspecting for Damage

Regularly inspect your composite decking for signs of damage, such as cracks, splits, or loose fasteners. Any issues should be addressed as soon as possible to avoid them worsening. Tighten any loose screws or rivets and replace any damaged boards according to the manufacturer’s guidelines.
