Composite wood decks are a popular choice for homeowners seeking beauty, durability, and low maintenance. But “low maintenance” doesn’t mean no maintenance. Over time, composite decks can accumulate dirt, mold, mildew, algae, and stains—dulling their appearance and potentially creating slippery, unsafe surfaces.

If you’ve noticed your deck isn’t looking as fresh as it once did, or if you’re simply trying to protect your investment, regular professional cleaning should be part of your exterior maintenance plan.

What Makes Composite Decks Unique?

Unlike traditional wood, composite decking is made from a blend of recycled wood fibers and plastic. This combination resists rot and insect damage, but it can still collect:

• Organic material like leaves and pollen
• Mold and mildew, especially in shaded or damp areas
• Surface stains from food, drink, or grill grease
• UV damage that causes fading

When these issues go untreated, they not only degrade your deck’s appearance—they can shorten its lifespan.

The Risk of DIY Cleaning

While many homeowners attempt to clean their decks themselves, improper pressure washing techniques can cause more harm than good.

The wrong pressure or nozzle can gouge or scratch the surface. Some chemical cleaners can damage composite materials or leave a chalky residue.

That’s where our professional services come in.

How Often Should You Clean a Composite Deck?

We recommend a full professional cleaning at least once a year, ideally in the spring or early summer—before the deck gets heavy use. For shaded or moisture-prone areas, twice a year may be necessary to prevent slippery buildup.
