Composite Decking Care and Maintenance Tips for Colorado Homeowners.
Composite decking like Trex and TimberTech has become one of the most popular alternatives to natural wood decking - and for good reason. Made from a mix of recycled wood fibers and plastics, composite boards are designed to be durable, low-maintenance, and long-lasting.
Unlike traditional wood, composite decking won’t splinter, requires very little upkeep, and is available in a wide variety of colors and textures that mimic the look of real wood grain.
That said, while composite decking is much easier to care for than wood, it isn’t completely maintenance-free. A little attention goes a long way in helping your deck keep its “like-new” look, especially in our challenging Front Range area climate.

8 Tips To Clean and Maintain your Composite Deck.
1. Avoid Standing Water.
Composite decking resists moisture better than wood, but standing water can still lead to mold or mildew growth—especially with Colorado’s mix of warm days and cool nights. Keep your deck free of puddles by regularly sweeping away leaves and debris that can trap water.
2. Allow Airflow Underneath.
Good ventilation helps your deck dry out quickly. Aim for at least six inches (preferably more) of open space beneath your deck so air can circulate freely. This airflow is especially important in shaded yards or areas where snow tends to linger.
3. Redirect Downspouts.
Don’t let roof runoff pour directly onto your deck. Make sure gutters and downspouts are directed away from the surface to reduce excess water exposure.
4. Choose Breathable Rugs.
Rubber-backed mats trap moisture and can leave marks on composite decking. Instead, opt for woven rugs or mats that allow the surface underneath to breathe. Even better, avoid rugs or mats which can potentially be a slip hazard.
5. Watch Dryer Vents Exhaust.
If your dryer vents near your deck, redirect it if possible. Dryer exhaust carries warm, moist air that can raise deck surface temperatures and encourage organic growth.
6. Limit Mulch Against the Deck.
Organic mulch may look tidy, but it holds moisture. Keep mulch away from direct contact with your deck boards. If you need ground cover around or under your deck, choose gravel or inorganic mulch instead.
7. Handle Spills Promptly.
If you spill grease or oil, clean it right away with a gentle detergent designed to cut through grease. Quick and thorough action will help prevent staining.
8. Stick to a Cleaning Routine.
Composite decking resists stains, but it’s still a good idea to clean it regularly. Sweep your deck often—especially in the fall—to prevent leaves, grass, and dirt from clogging board gaps. If debris builds up, gently use a plastic spatula or putty knife to clear it, then rinse the deck with a garden hose.
For tougher dirt or salt residue (common in Denver winters), use a soft scrub brush, mild soap, and water. Avoid harsh chemicals or metal brushes that could damage the surface.

Composite Decking FAQs for Colorado Homeowners:
Is composite decking good for Colorado’s climate?
Yes. Composite decking is designed to handle moisture, temperature swings, and strong sunlight better than natural wood. With regular cleaning and proper installation, it can last decades in Metro Denver’s climate.
Does composite decking get hot in the sun?
Like any outdoor surface, composite decking will get warm under direct sun—especially at higher altitudes. Lighter colors tend to stay cooler, and proper ventilation underneath helps regulate surface temperatures.
How long does composite decking last?
Most composite decking products last 25–30 years or more with minimal maintenance, making them a long-term investment compared to traditional wood decking. Composite decking brands all carry long-term warranties.
Can I shovel snow off composite decking?
Yes—just be sure to use a plastic shovel instead of metal to avoid scratching the surface. You can also use rock salt sparingly, but be sure to rinse off residue in the spring.
Do I need to stain or seal composite decking?
No. Unlike wood, composite decking does not require staining, painting, or sealing. Routine cleaning is usually all that’s needed to keep it looking great.
