When planning an outdoor bench project, the cost comparison between plastic lumber (or composite) and traditional wood is a crucial first step. At first glance, traditional woods like pressure-treated pine or cedar often have a lower initial price per linear foot. Plastic lumber composites, however, typically come with a higher upfront cost.
But the true cost picture emerges over time. Traditional wood requires regular staining, sealing, or painting to prevent rot, insect damage, and weathering. These materials and labor add up year after year. Plastic lumber, made from recycled plastics and wood fibers, demands almost no maintenance—no splinters, no rotting, and no need for annual sealants. This means significant long-term savings.
Durability is another cost factor. A well-maintained wood bench may last 10-15 years, while a high-quality plastic lumber bench can last 20-30 years with minimal upkeep, effectively offering a better lifespan return on your investment.
For the environmentally conscious, plastic lumber often uses recycled materials, but its end-of-life recyclability can be complex. Sustainably sourced traditional wood is a renewable resource. Ultimately, your choice balances initial budget versus long-term value. If you prefer low upkeep and are willing to pay more initially, plastic lumber is cost-effective over decades. If you enjoy maintenance and have a tight immediate budget, traditional wood remains a beautiful, classic option.
