- Permits & Local Labor: City permits and local labor rates can also impact your budget.
Comparing Trex Decking Cost to Other Materials
When evaluating your Trex decking cost, it helps to compare it with other popular decking materials. While Trex often has a higher upfront price, it offers a longer lifespan and less maintenance than many alternatives:
- Pressure‑treated wood: Lower initial cost but requires frequent staining, sealing, and repairs over time.
- Cedar or redwood: Attractive natural look but higher maintenance needs and shorter lifespan compared to Trex.
- PVC decking: Similar low‑maintenance benefits, but often comes at an even higher cost per square foot.
By looking beyond the initial cost and factoring in long‑term maintenance, durability, and aesthetic value, many homeowners find that investing in Trex decking delivers better overall savings and satisfaction.
Why Trex Decking Is Worth the Investment
- Even with a higher upfront trex decking cost, Trex remains popular because it offers:
- Low Maintenance: No annual staining or sealing.
- Durability: Resistant to rot, warping, and pests.
- Sustainability: Made from recycled materials.
- Long-Term Value: Adds curb appeal and can boost home resale.
