Composite Deck Maintenance 101: Everything You Need To Know

Composite decks are favored by homeowners for their minimal maintenance needs. That being said, any composite deck is a hefty investment. To get the most bang for your buck, you’ll want to make sure you take care of it over time. Here are some composite deck maintenance tips to keep your space looking and performing great for years to come. 

Does Composite Decking Need Maintenance?

Trex composite decks are made from a mixture of recycled wood fibers and plastic. TimberTech AZEK’s is made from high-quality PVC. Both of these composite decking materials are top-notch wood alternative materials for decks.

Builders and homeowners alike rave about the fact that they’re both long-lasting, don’t splinter, and requires minimal maintenance and care. 

That being said, you might be asking yourself, “Does composite decking need maintenance at all?” The simple answer is “yes.” Caring for your deck is always important so you can increase longevity and maintain the appearance as much as possible. Don’t worry – composite deck maintenance is easy when you follow our tips! 

Tips To Prevent Composite Decking Damage

  • Avoid standing water – Although composite decking is designed to resist water and rot, you should still do whatever you can to minimize liquid sitting on the material for long periods. This will help to prevent mold and mildew growth. 
  • Redirect rainspouts – It’s not ideal to have rainwater runoff splashing down on your deck. Avoid this by pointing rainspouts away from your deck so the material isn’t exposed to excess moisture. 
  • Ventilate the underside of your deck – Your deck will dry faster when air can circulate underneath it. Therefore, you should make sure the surface of the deck sits at least six inches above the ground. 
  • Minimize mulch – Organic mulch can be damaging to your deck. Opt for inorganic mulch or gravel instead. 
  • Don’t trap moisture – Welcome mats with rubber backing can trap moisture. Purchase woven rugs instead since they breathe better. 

How To Maintain Your Composite Decking

  • Unclog board gaps – It’s common for leaves, grass, and other debris to get stuck in the gaps between your composite deck boards. If you notice buildup, use a spatula or knife to get them out and spray the area with a garden hose. 
  • Sweep your deck – Sweeping regularly is one of the best and easiest ways to prevent dirt and debris from getting caught in the deck gaps, especially during the fall months. 
  • Remove dirt and salt – Our shoes are constantly tracking dirt (and rock salt during wintertime) wherever we walk. Clean the area by sweeping. If that doesn’t do the trick, use a soft-bristled scrub brush with warm soapy water.  
  • Avoid oil and grease – If you ever spill food on your deck, you must clean it up right away to help prevent stains. When there is a grease stain, wash the affected area with a mild detergent to cut through the oils.

Can You Pressure Wash a Composite Deck?

If you think your deck could use some sprucing up, you can pressure wash it. However, you must use a pressure washer that is no greater than 3100 psi and has a fan attachment. 

Spray the surface with soap and gently scrub each deck board with a soft bristle brush. Then, spray/rinse each individual board with a fan tip (don’t get closer than 8 inches). Be sure to rinse the area thoroughly to avoid a film developing. 

Are There Specific Composite Deck Cleaners?

One of the biggest pros of owning a composite deck is that you can conveniently maintain and clean it with household products. However, if you’re interested in composite deck cleaners that’s an option as well. 

Before using one of these composite cleaners, be sure to consult the deck manufacturer. They will let you know if it’s safe to use on your deck or not. 

For example, Trex recommends using a composite deck cleaner semi-annually, but only with their early generation composite products.
