How to Maintain Composite Decking in the Fall: Keep Your Deck Looking Its Best

What Makes Composite Decking a Top Choice

If you’re considering building a composite deck or have just put one in, it helps to know what sets it apart. Composite decking combines wood fibers with recycled materials, creating a deck that’s designed to be durable and easy to care for. Unlike traditional wood, it resists rot, fading, staining, and insect damage, so you get all the beauty of wood without the high maintenance. For homeowners looking for a long-lasting, low-maintenance option, explore our composite decking collection for options that bring both style and functionality to any outdoor space.

To keep your composite deck looking its best this fall, a little seasonal care can go a long way. Here are a few simple tips to help maintain that fresh, just-installed look year-round.

Establish A Regular Cleaning Routine

Fall leaves might look picture-perfect on your deck, but letting them pile up can lead to trouble. As the season brings more fallen leaves and debris, it’s a good idea to make cleaning a regular ritual. Grab your trusty broom or leaf blower and give your deck a quick sweep each week. A broom works great for those nooks and crannies, while a leaf blower makes clearing the whole deck a breeze.

Give Your Deck A Wash

Fall is an excellent time for cleaning composite decking and washing away any grime that may have built up over the summer. While it can be tempting to power wash composite decking, always check the manufacturer’s guidelines first, as some materials may require gentler methods to avoid surface damage.

• If power washing is approved for your deck type, use a low setting to protect the surface

• Alternatively, use a hose or a bucket of soapy water with a soft-bristle brush to scrub the surface

• After cleaning, rinse thoroughly with clean water to remove any soap residue

Regular cleaning—whether by hand or by power wash if suitable—will help maintain the appearance and integrity of your composite decking throughout the fall.

Fall Lighting Tips for Your Deck

As daylight hours get shorter, deck lighting becomes even more essential for safety and ambiance. Check all outdoor lights for functioning bulbs and clean off any dirt or cobwebs that may have collected. If you’re considering an upgrade, LED deck lighting offers energy efficiency and longevity. For a welcoming and cozy glow, explore our selection of deck lighting options, which includes options for railings, stairs, and post caps to enhance both aesthetics and functionality on your deck.

Preventing Mold and Mildew on Composite Decking

Fall weather brings increased humidity and moisture, which creates ideal conditions for mold and mildew. To combat this, use a composite deck cleaner designed for removing mold and mildew. Composite decks are easier to clean compared to traditional wood decks, making them a low-maintenance and durable alternative for homeowners. Always follow the manufacturer's instructions, and rinse thoroughly after cleaning to prevent residue from lingering.

In addition to cleaning, trim back any nearby vegetation or landscaping that may obstruct airflow around your deck. Overhanging branches can drop leaves or sap onto your composite deck, causing issues over time. By taking these preventive steps, you can keep your composite decking looking pristine and extend its lifespan.

Protect Against Stains

Fall’s outdoor gatherings are made for cozy cups of hot cocoa and chili cookouts, but these moments come with the risk of accidental spills. To keep your deck looking its best, consider adding a few protective touches where food and drinks are served. An outdoor rug can do wonders—just make sure it’s safe for composite decking to avoid any color transfer.

• Wipe up spills as soon as they happen to prevent staining.

• Place a deck-safe outdoor rug in high-traffic areas where food or drinks are served.

• Avoid rubber-backed mats, as some contain substances that may discolor or lighten the decking surface.

• Keep metal items from staying wet on the deck to avoid rust stains, which can be tough to remove.

Inspect and Repair Damage

Before winter arrives, give your composite decking a thorough inspection to catch any signs of wear. Check for loose boards, cracks, or scratches that might need attention, and examine fasteners, screws, and metal connections. Pay special attention to guardrails and the ledger board to ensure everything is secure. Tighten any loose screws or bolts, and replace rusted or damaged fasteners to maintain stability. For added peace of mind, gently tap metal bolts—if secure, they’ll sound solid, while a loose bolt may produce a hollow ring.

If you notice any damaged boards or fittings, replace them promptly to uphold the structural integrity of your deck. Our hardware collection offers a range of durable fittings and fasteners to keep your deck secure and in top shape year-round.
