The cost of Trex decking can vary, with most prices averaging twice the amount of pressure-treated wood. However, Trex is also a composite material that requires very little maintenance once it has been installed. Since pressure-treated wood decking requires staining and sealing on a yearly basis, the Trex decking may be the more cost-effective over time. Still, those consumers who are focused on a lower up front installation cost, may prefer to opt for the pressure-treated wood decking and worry about maintenance charges later.
Pressure-treated wood decking usually carries no warranty other than the one that is offered by the installation company, but composite decking commonly includes a warranty from the manufacturer itself. In fact, companies that manufacture composite decking, boast of its durability and resistance to warping and rotting. Therefore, company's like the manufacturer of Trex, cover their building materials for periods of approximately twenty-five years from the date of purchase. However, Trex is only one of several manufacturers' of composite decking materials, so warranties will vary by company.
Trex decking offers a skidproof surface that will decrease the likelihood of injuries due to slips and falls after heavy rain or around the pool area. Unfortunately, the same can not be said for pressure-treated wood decking. Yet another advantage that Trex has over pressure-treated wood is that it won't break, split, or splinter. Homeowners will not have to worry about painful injuries while walking barefoot during the summer months.
For those who are concerned about environmental issues such as, the number of trees that are harvested for construction purposes, including the manufacture of pressure-treated wood decking materials, Trex may be a satisfying alternative. Comprised of fifty percent recycled materials, which include the use of plastic bags and leftover sawdust, Trex decking offers the look of real wood, with a less harmful effect on the environment.
