Building a deck is a popular way to enhance outdoor living space, but choosing the right material can be confusing. Two common options are Trex decking and pressure-treated wood. Both have their advantages, but they differ significantly in cost, maintenance, and longevity. This post breaks down the costs of Trex decking compared to pressure-treated wood and highlights the benefits of each to help you make an informed decision.

Comparing Initial Costs
When planning a deck, the upfront cost is often the first consideration. Trex decking is a brand of composite decking made from recycled wood fibers and plastic. It is known for durability and low maintenance but comes with a higher price tag.
Trex decking material cost: On average, Trex decking costs between $30 and $45 per square foot, including materials and installation. The price varies depending on the style and finish chosen.
Pressure-treated wood cost: Pressure-treated wood typically costs between $15 and $25 per square foot, including materials and installation. This makes it a more budget-friendly option initially.
The difference in upfront cost can be significant. For a 300-square-foot deck, Trex could cost between $9,000 and $13,500, while pressure-treated wood might range from $4,500 to $7,500.
Long-Term Cost Considerations
While pressure-treated wood is cheaper initially, it requires more maintenance over time. Trex decking, though more expensive upfront, can save money in the long run.
Maintenance Costs
Pressure-treated wood: Needs regular sealing, staining, or painting every 2 to 3 years to prevent rot, warping, and insect damage. These maintenance tasks can cost $500 to $1,000 every few years, depending on deck size and labor costs.
Trex decking: Requires minimal maintenance. Cleaning with soap and water once or twice a year is usually enough. No sealing or staining is necessary.
Durability and Lifespan
Pressure-treated wood: Typically lasts 10 to 15 years before major repairs or replacement may be needed.
Trex decking: Can last 25 years or more with proper care, resisting fading, splintering, and insect damage.
Over time, the maintenance and replacement costs for pressure-treated wood can add up, potentially surpassing the initial savings compared to Trex.
Environmental Impact
Trex decking is made from recycled materials, including plastic and wood fibers, which helps reduce waste. Pressure-treated wood comes from harvested trees and is treated with chemicals to resist decay.
Choosing Trex supports recycling efforts and reduces the demand for new lumber. However, some homeowners prefer the natural look and feel of real wood, which pressure-treated wood provides.
Appearance and Comfort
Trex decking offers a consistent, polished look with a variety of colors and finishes that resist fading. It also stays cooler in direct sunlight compared to some other composite materials.
Pressure-treated wood has a natural wood grain and can be customized with stains or paints. However, it may develop splinters and cracks over time, which can affect comfort and safety.
Installation Differences
Both materials can be installed by professionals or experienced DIYers, but Trex decking requires specialized fasteners and tools designed for composite materials. Pressure-treated wood uses standard nails or screws, making it easier for some to install.
Summary of Key Points
Feature | Trex Decking | Pressure-Treated Wood |
Initial Cost | $30–$45 per sq. ft. | $15–$25 per sq. ft. |
Maintenance | Low (cleaning only) | High (sealing, staining needed) |
Lifespan | 25+ years | 10–15 years |
Environmental Impact | Made from recycled materials | Uses treated natural wood |
Appearance | Consistent, fade-resistant colors | Natural wood grain, customizable |
Installation | Requires special fasteners | Uses standard nails/screws |

Making the Right Choice
Choosing between Trex decking and pressure-treated wood depends on your budget, maintenance willingness, and aesthetic preferences.
If you want a low-maintenance, long-lasting deck and are willing to invest more upfront, Trex decking is a strong choice.
If you prefer a lower initial cost and enjoy regular upkeep or want the natural wood look, pressure-treated wood may suit your needs.
