Your Fiberon deck is an investment worth protecting. While composite decking is designed to be low maintenance compared to traditional wood, a bit of regular care will keep it looking beautiful and performing well for decades.
Does Composite Decking Need Maintenance?
Composite decking offers significant advantages over wood — it won't rot, split or warp, and you'll never need to sand, stain or seal it. That said, "low maintenance" doesn't mean "no maintenance." The good news? Upkeep is surprisingly easy. By following these simple composite decking maintenance tips, you'll enjoy your deck for years to come.
Basic Cleaning Routine
Weekly Sweeping
A quick weekly sweep removes fallen leaves, dirt and debris before they can decompose on your deck surface. This simple habit prevents organic material from causing staining or promoting mold growth.
Clean up Spills Quickly
Address spills as they happen. Whether it's barbecue sauce from your summer cookout or sunscreen from a pool day, wiping spills immediately with warm, soapy water and a soft-bristle brush prevents stains from setting in.
Monthly Cleaning
Once a month (weather permitting), give your deck a more thorough cleaning with mild dish soap diluted in warm water. A gentle scrub with a soft brush followed by a garden hose rinse will keep your deck fresh and clean. Don't forget to clean between deck boards where debris often accumulates, potentially blocking drainage channels. Corner areas and spaces under furniture also need regular attention to prevent buildup.
Proper Cleaning Tools
Use the right tools to protect your composite deck:
- Soft-bristle brushes for general cleaning
- Microfiber cloths for drying or detail cleaning
- Plastic snow shovels for winter (never metal)
- Rubber or plastic scrapers for stubborn spots
Seasonal Maintenance Guide
Spring
As the weather warms, it's time for a post-winter inspection:
- Check for any loose fasteners or boards that may have shifted during freeze-thaw cycles.
- Deep clean to remove winter grime and spring pollen using a composite-specific deck cleaner.
- Look for any damage that may have occurred during the winter months.
Summer
Summer brings heavy deck usage and unique challenges:
- Use protective barriers under grills to catch grease drips before they stain your deck.
- Apply protective pads under furniture legs to prevent scratching.
- Pay extra attention to high-traffic areas that may need more frequent cleaning.
Fall
Autumn preparation helps protect your deck through winter:
- Stay on top of leaf removal to prevent staining and moisture retention.
- Clean gutters and downspouts to ensure proper drainage away from your deck.
- Clear debris from between boards to prevent water accumulation.
- Consider a thorough cleaning before winter arrives.
Winter
Even in the cold months, some maintenance helps to protect your investment:
- Use plastic snow shovels only to avoid gouging the surface.
- Choose calcium chloride or rock salt for ice, avoiding products with colorants.
- Try not to pile snow repeatedly in one area, which can cause uneven weathering.
- Remove ice and snow when possible to reduce moisture.
Important Do's
DO use manufacturer-approved cleaning products.
DO maintain proper ventilation and airflow under and around your deck to prevent moisture buildup and potential mold issues.
DO conduct regular inspections of structural elements, including the substructure, fasteners and board connections.
DO ensure proper drainage both on and around your deck to prevent standing water, which can lead to staining and structural issues over time.
DO use protective mats under furniture, especially those with metal feet, but choose breathable options that won't trap moisture.
Important Don'ts
DON'T use pressure washers exceeding 2,500 psi and always maintain a distance of at least 12 inches from the deck surface when using one. Better yet, opt for standard garden hose cleaning when possible.
DON'T use metal shovels, sharp-edged tools or abrasive scrubbers that can scratch and damage the protective cap of your composite boards.
DON'T place solid rubber mats on your deck surface. These trap moisture and can lead to discoloration or mold growth. Choose breathable options instead.
DON'T apply harsh chemicals, chlorine bleach or solvent-based cleaners that can break down the composite material and cause permanent damage.
DON'T attempt to paint, stain or seal your Fiberon composite decking. Unlike wood, it doesn't require these treatments.
Troubleshooting Common Composite Deck Issues
Surface Scratches
Minor scratches often weather away naturally over time. For deeper scratches, a light sanding with fine-grit sandpaper followed by careful heat application (such as from a heat gun) can help blend the area.
Managing Fading
Some degree of lightening is normal for composite decking in its first year. To minimize UV-related fading:
- Use patio furniture covers to provide shade
- Consider breathable outdoor rugs in high-sun areas
- Rotate furniture
Mold and Mildew
If you notice mold or mildew:
- Clean with a commercial deck cleaner containing a mildewcide
- Improve airflow around affected areas
- Ensure proper drainage to eliminate standing water
- Trim nearby vegetation to increase sunlight exposure
Fixing Loose Boards
Periodically check and tighten any loose fasteners. For hidden fastener systems, consult your installation guide for proper adjustment techniques.
Long-term Deck Protection Tips
Furniture Rotation
Rotate the placement of heavy furniture periodically to prevent uneven weathering. Always use furniture protectors under legs, especially metal ones.
Drainage Solutions
Ensure proper slope away from your house (¼ inch per foot is recommended). Consider additional drainage improvements if water tends to pool near your deck.
Professional Assessment
Consider having a deck professional inspect your structure every two to three years to identify any potential issues before they become serious problems.
Fire-Rated Composite Decking Maintenance
If you've invested in Fiberon's fire-rated composite decking for added safety, the good news is that maintenance remains largely the same as standard composite decking. Fire-rated composite boards contain special flame-retardant additives that help resist ignition and slow flame spread. To maintain these important safety properties:
- Keep your fire-rated deck clean of leaves, pine needles and other flammable debris
- Be especially vigilant about cleaning between boards where combustible materials can accumulate
- Never use accelerants like lighter fluid near your deck
- Maintain proper clearance between your deck and any fire features or grills
With minimal but consistent care, your Fiberon composite deck will remain beautiful and functional for decades. The small investment in regular cleaning and seasonal maintenance protects your larger investment in your outdoor living space.
