Advantages of Composite Decking


Less maintenance

We’re all busy these days. People are hustling around the clock but wish they could spend some more time with family and friends. Hence, it is indeed valuable to have an outdoor space that requires only minimal maintenance. 


In contrast, wood decking is prone to rot and mold, leading to lots of maintenance. With composite decking, you don’t have to worry much about this aspect as they are resistant to rot and easy to maintain. Beyond that, composite decks do not require resealing and repainting. However, we still suggest you clean your composite deck regularly, which can be done with soap and water.

Durability & Lifespan

Every homeowner aims to have every part of their house as durable as possible. This is why composite decking makes an excellent choice. They make a durable option as they are made of plastic and wood. Wood decking can last up to 10-15 years, whereas composite decks can last up to 30 years or more. Furthermore, they do not stain or fade, making them a good option for families with children and pets.


It’s Environmentally friendly

Since composite decking is made of recycled plastic and wood, it is considered to be an environmentally friendly option. This means less energy and waste go into manufacturing when building this material. You can have the outdoor space of your dreams without worrying about harming the environment.


Disadvantages of Composite Decking


Hot Decking

Some homeowners complain about the temperature of their composite decks. The truth is, composite decks retain and absorbs heat when exposed to direct sunlight. It’ll take hours for the boards to cool down before you can comfortably walk on them. Aside from preventing you and your loved ones from enjoying your investment on a sunny day, scorching decks can put your pets and kids at risk of burns.


Expansion and Contraction Leads to Damage

Composite decks have a higher rate of contraction and expansion caused by temperature swings. They move in great distances compared to traditional wood. The tendencies are your deck boards may bend, twist, and peel as soon as they expand. Damaged composite decks must be replaced immediately.


Susceptible to Mold

Most composite decking manufacturers label their products to be totally “mold-resistant,” but since they contain wood, they still have the tendency to moist and rot. Uncapped composite decks leave the primary ingredients vulnerable to rotting. Fully encapsulated composite boards, on the other hand, offer more protection. Still, moisture can enter the boards through their holes. Mold develops either inside or on the surface, especially when the boards are wet and when boards cannot dry out immediately.


Not Intended For Structural Support

If you wish to have a composite decking for your outdoor space, be reminded that in order to maximize its lifespan, you will need to have it pressure treated. Otherwise, your composite deck’s lifespan will decrease because it is initially made of wood and will rot underneath the boards. Ensure that your deck contractors won’t skip this step by using natural wood with a water-resistant stain.
