Composite Decking Vs. Traditional Wood

Deciding between composite decking and traditional wood decking can be difficult for many homeowners. Each type of material has its own set of advantages and disadvantages. Most of these factors balance each other out, making the choice a matter of personal preference when it comes to the appearance of the deck. Choose the material before laying the framework for the deck, as composite decking requires the support beams to be placed closer together to handle the extra weight.

Materials

Wood decking is generally made out of a hardwood like redwood, cedar or pine. The wood is pressure-treated to improve its resistance to water and pests. Composite decking is made from a blend of synthetic materials such as vinyl or PVC and recycled wood fiber. Blending the wood fiber into the mix gives composite decking a natural appearance without sacrificing durability.

Durability

The main advantage of composite decking over wood is its durability. Because the composite is primarily made up of synthetic material, it is not susceptible to damage from termites and will not rot from exposure to moisture. Composite decking also does not crack or splinter like traditional wood. However, staining and scratching can be a problem when using composite decking. Depending on the color of the composite decking, it may become faded after prolonged exposure to the sun.

Maintenance

Wood requires far more maintenance than composite decking. Composite material only needs to be cleaned periodically to keep it from looking dirty or washed out. Traditional wood must be stained and treated with a waterproofing sealant every year or two so that it remains protected from the elements.

Cost

Composite decking costs more than traditional wood. When averaged out over the life of a deck, it is often less expensive to use composite material because it lasts so much longer than wood. A wooden deck may need to be replaced several times before a comparable deck made from composite. Consider how long you intend to keep the home when deciding if the added cost of composite is worth it to you. If you will be selling the home in five years or less, you probably will not receive any benefit from the composite's longer life.

Appearance

Wood remains the preferred choice for decking because of its appearance. The natural grain and rich color of the wood still cannot be replicated by a composite material. However, the quality of composite decking has improved over the years, giving today's consumer a variety of choices that are very similar to the look of natural wood. Colored composite decking is also available, allowing homeowners to use their outdoor deck as a way to accent the color of the home.
