Use the Pro’s and Con’s accordian below to help you make the right choice for your next decking project

Pressure Treated Decking

Pros

  • No. 1 decking material sold in the U.S.
  • Most pressure treated (PT) decking is milled from Southern Yellow Pine
  • Chemically treated to resist rot, fungus and wood-boring bugs
  • Common sizes used in New England are 5/4″ x 6″. 5/4″x4″ is also available

Cons

  • Not very dimensionally stable
  • Has a tendency to crack, split and warp
  • Routine maintenance is necessary to prolong the life and look of the deck
Cedar Decking

 

Pros

  • Prized for its rich color and natural beauty
  • Dimensionally stable, resistant to cupping and twisting
  • Contains tannins and oils that makes it naturally resistant to rot, decay and insects
  • Weathers to a soft silvery gray when no finish is applied

Cons

  • Higher cost than pressure treated decking
  • Must be low-pressure cleaned every year to maintain natural cedar color
  • Clear water-repellent wood preservative should be applied yearly
Hardwood Decking

Pros

  • Exotic rich-grained woods
  • Available in 5/4″x4″ or 5/4″x6″ widths
  • Hard and durable, naturally resistant to rot and insects.
  • Will weather to a soft silvery color if not stained

Cons

  • Relatively expensive when compared to Pressure Treated decking
  • Use an oil-based penetrating stain specifically formulated for hardwood decking,
  • Allow the wood to weather one to three months before finishing, so that excess oils can leach out
  • Finish should be applied to both ends of every board as extra protection against checking
  • Should at least apply a UV-blocking clear wood preservative every three to four years.
Composite and PVC Decking

Pros

  • Extremely low-maintenance, never need to be sanded or refinished
  • Composites and plastic lumber come in sizes similar to wood decking, including 2 “x 6″ and 5/4″ x 6”
  • Most products are made from polyethylene or polyvinyl chloride, and come in a wide range of colors and finishes
  • Composites like Trex are composed primarily of wood fibers and recycled plastic – the result is an extremely weather and stain resistant board that won’t splinter, warp, rot or split
  • Plastic lumber like Azek Deck is made from 100 percent plastic (recycled and/or virgin), contains no wood fibers, and is also highly resistant to staining and decay
  • Most decking manfacturers also offer a line of handrails, balusters, fascias and other decorative trim

Cons

  • Composites and plastic lumber decks are low maintenance, NOT maintenance-free
  • Mold and mildew can grow in shaded, damp areas of the deck
  • Some composites can eventually show signs of decay as they are partly wood

Since 1996, Trex has invented, defined and perfected the composite deck category with a lineup of low-maintenance, high-performance, eco-friendly products that fundamentally change the way we live outdoors.
