Composite decking has gained immense popularity over the years due to its durability, low maintenance, and eco-friendly attributes. However, like any building material, it has its challenges.
This comprehensive guide will explore twelve common problems homeowners may encounter with composite decking and provide practical solutions and tips to address them.
By understanding and proactively managing these issues, you can ensure that your composite deck remains a beautiful and long-lasting addition to your outdoor space.
Common Problems with Composite Decking and Solutions
Fading and discoloration
Problem: One of the primary concerns with composite decking is fading and discoloration over time. Exposure to sunlight, especially in regions with intense UV rays, can cause the deck’s color to fade, making it appear dull and less appealing.
Solution: To minimize fading, select composite decking products with UV inhibitors or protective coatings. Additionally, consider using lighter-colored composite boards, which fade less than darker shades. Regularly clean your deck to remove dirt and debris, which can contribute to discoloration.
Scratches and Scuffs
Problem: Although composite decking is highly durable, it can still be susceptible to scratches and scuffs, especially in high-traffic areas or when moving furniture.
Solution: Place furniture pads or coasters under heavy items to prevent scratches. Avoid dragging furniture across the deck’s surface when moving furniture or other objects. If scratches occur, lightly sand the affected area, blending it with the surrounding surface.
Always follow the manufacturer’s guidelines for repair and maintenance to avoid further damage.
Mold and Mildew Growth
Problem: Despite being resistant to rot and moisture, composite decking can still develop mold and mildew, particularly in areas with high humidity or poor ventilation.
Solution: Regularly clean your deck to remove organic matter, which can provide a breeding ground for mold and mildew.
Use a mild detergent or a composite deck cleaner with a soft brush to scrub away any signs of growth. Ensure proper ventilation around the deck to reduce moisture accumulation.
Staining
Problem: Stains from spills, grease, or other substances can mar the appearance of your composite deck, leaving unsightly marks.
Solution: Act quickly to clean up spills to prevent staining. Use a composite deck cleaner or a mixture of mild detergent and water for stubborn stains. Avoid harsh chemicals or abrasive tools, which can damage the deck’s surface.
Heat Retention
Problem: Composite decking can retain heat, making the surface uncomfortable to walk on during hot summer days.
Solution: Choose lighter-colored composite boards, which absorb less heat than darker shades. Consider using outdoor rugs or mats in high-traffic areas to reduce direct exposure to the hot deck surface.
Expansion and Contraction
Problem: Like all materials, composite decking expands and contracts with temperature changes, leading to gaps or warping over time.
Solution: Follow the manufacturer’s installation guidelines to ensure proper spacing between deck boards.
Use the recommended fasteners to allow for natural expansion and contraction. Additionally, avoid installing composite decking in areas with extreme temperature fluctuations.
Structural Integrity
Problem: In some cases, composite decking may experience sagging or structural issues, especially if the substructure must be fixed or installed correctly.
Solution:Ensure a sturdy and well-supported subframe for your composite deck. Use pressure-treated lumber or composite joists and correctly secure them to the support posts.
Regularly inspect your deck for any signs of sagging or structural problems and address them promptly.
Warping and Bowing
Problem: Composite decking can experience warping and bowing over time, especially in areas with extreme temperature variations or inadequate substructure support.
Warping and twisting can lead to an uneven and unattractive deck surface, compromising its functionality and aesthetics.
Solution: Proper installation is vital to preventing warping and bowing. Construct the subframe with the correct spacing between joists and securely anchor it to support posts. Use the manufacturer’s recommended fasteners to allow for expansion and contraction.
Regularly inspect the deck for signs of warping and address any issues promptly. If distortion occurs, consult a professional to determine the best course of action for correction or replacement.
Slippery Surface
Problem: Composite decking, like any outdoor flooring material, can become slippery when wet, posing a safety hazard, especially in regions with frequent rain or high humidity.
Solution: Consider using non-slip deck coatings or adding slip-resistant strips to high-traffic areas to enhance traction on your composite deck. Regularly clean your deck to remove algae or mildew, which can contribute to slippery surfaces.
Alternatively, opt for composite decking products with textured surfaces or embossed patterns to provide a better underfoot grip.
Edge Fading
Problem: Some composite decking boards may experience edge fading, where the color appears lighter at the edges due to sun exposure.
Solution: Choose composite decking with protective caps or wraps that extend over the entire board, providing extra protection against edge fading. Alternatively, you can use a stain marker or touch-up pen that matches the color of your deck to minimize the appearance of faded edges.
Environmental Considerations
Problem: Although composite decking is eco-friendly in using recycled materials, the production process and disposal of composite boards can still have environmental impacts.
Solution: Look for composite decking brands that prioritize sustainable practices and use environmentally friendly production methods.
Some manufacturers use renewable energy sources or have recycling programs for old composite decks. When the time comes to replace your deck, explore options for recycling or repurposing the old materials.
Proper Cleaning and Maintenance
Problem: Neglecting routine cleaning and maintenance can intensify the problems associated with composite decking, leading to more significant issues over time.
Solution: Implement a regular cleaning schedule to keep your composite deck in top condition. Sweep away debris and dirt regularly and hose down the surface with water.
Use a composite deck cleaner and a soft brush for more thorough cleaning. Avoid using pressure washers at high settings, as they can damage the deck’s surface.
Address any issues promptly and follow the manufacturer’s maintenance guidelines to ensure your composite deck’s longevity.
Conclusion
While composite decking offers numerous advantages, understanding and addressing its potential problems is essential to maintaining a beautiful and functional outdoor space.
You can proactively manage and mitigate potential issues by being aware of the common problems and implementing the solutions and tips in this guide.
Choose high-quality composite decking products, follow proper installation techniques, and maintain your deck regularly to preserve its beauty, functionality, and durability for years.
