Composite Decking Vs. Treated Lumber

Composite decking has a uniform look.

Depending on the size and complexity of the design,building a deck can be a major undertaking. The type of decking material you choose is more than a minor consideration. Be aware of the advantages and disadvantages of each before you make your final choice.

Composite

Composite decking is made from wood and recyclable plastic materials. Composite decking wins with a homeowner who wants a deck that is easier to maintain. Composite decking is water resistant and doesn't require staining and varnishing. It's also a good choice for decking near a swimming pool.

Treated Lumber

Treated lumber is all natural and durable. These fundamental qualities, combined with wood's aesthetic appeal, make it a favorite for many homeowners. Treated lumber requires a fair degree of annual maintenance and weather proofing. However, by doing so, the deck can last well over 20 years.

Similarities

Both composite decking and treated lumber may be used to create a deck surface that is flat, level and able to support a great deal of weight without chipping or crumbling, like masonry or stone. Both pose environmental concerns: Wood decking uses lumber from forests, and composite decking contains plastic.

Differences

Matching replacement boards is harder with treated lumber decks. Composite decking boards are relatively uniform in appearance. In terms of cost, treated lumber decks are less expensive to install.
