Proper Ways to Take Care of Your Composite Wood Fence or Deck

While composite wood structures are durable and low-maintenance, proper care extends their lifespan and keeps them looking beautiful. This guide provides comprehensive maintenance tips for homeowners with composite fences and decks.

Understanding Composite Wood

Composite wood comprises wood fiber, plastic, and binding agents that are heated and compressed to create weather-resistant structures. Unlike traditional wood, composite materials resist splintering and rot, but they still benefit from regular care.

Seasonal Maintenance Guidelines

Spring & Summer Care

1. Remove furniture and decorations from the surface
2. Sweep with soft-bristled brushes to remove debris
3. Clean using mild soap or specialized composite cleaner
4. Rinse thoroughly with a garden hose
5. Allow to air dry completely

Fall & Winter Care

• Clear leaves and debris regularly to prevent mold growth
• Use plastic shovels for snow removal—avoid metal tools that may scratch surfaces
• Keep drainage areas clear

Regular Inspections

Monitor your composite fence or deck for:

• Loose boards or fasteners
• Discoloration or staining
• Mildew spots (especially in shaded areas)
• Structural integrity issues

Stain & Scratch Management

For stains, apply soap and water first. For stubborn stains, consider specialty composite cleaners. Always test cleaning solutions on a hidden area before widespread use. For minor scratches, a wire brush can gently buff the affected area.

Protection Strategies

• Ensure proper water drainage
• Keep surfaces debris-free
• Use furniture pads under heavy items
• Keep yards pest-free
• Trim vegetation that contacts the fence or deck

When to Call Professionals

Contact a professional for severe stains that don't respond to cleaning, deep scratches affecting the surface integrity, structural damage or warping, and any repairs beyond routine maintenance.
