If you are planning to build or replace a deck, one of the first questions you will ask is: how much does it cost? A deck is more than just a platform in your backyard. It is an extension of your home, a place for gatherings, relaxation, and increasing your property value.
When it comes to materials, many homeowners find themselves choosing between traditional wood and Trex® composite decking. Trex® is the world’s leading brand of composite decking, and for good reason. It offers unmatched durability, low maintenance, eco-friendly materials, and warranties that protect your investment for decades. But what about the cost?
This guide will break down the installation costs of Trex® composite decking, including material prices, labor rates, factors that affect overall expenses, and how Trex® compares to wood. By the end, you’ll know exactly what to expect when budgeting for your new deck.
Why Choose Trex® Composite Decking?
Before diving into costs, it is important to know why Trex® is such a popular choice among homeowners. Compared to wood decking, Trex® offers:
- Durability: Resistant to rot, mold, and insect damage.
- Lifespan: 25 to 50 years depending on the product line.
- Low Maintenance: No sanding, staining, or sealing required.
- Eco-Friendly Materials: Made from 95% recycled plastic and reclaimed wood fibers.
- Warranty Protection: 25-, 35-, or 50-year limited residential warranties depending on the product line.
For North Carolina homeowners especially, where humidity and weather fluctuations wreak havoc on wood decks, Trex® is a proven long-term solution.
Material Costs for Trex® Composite Decking
Trex® offers three primary product lines, each at different price points:
Trex® Product Line | Material Cost (per sq ft) | Warranty | Description |
Trex Enhance® | $12–$15 | 25 years | Affordable, practical option for budget-conscious homeowners. |
Trex Select® | $15–$18 | 35 years | Mid-tier decking with balanced performance, richer colors, and improved style. |
Trex Transcend® | $18–$22 | 50 years | Premium, luxury-grade decking with the highest durability and longest lifespan. |
Labor Costs for Installation
Labor is often the largest variable in deck construction. On average, Trex® deck installation labor costs between $15 and $40 per sq ft, depending on:
- Deck size and design complexity
- Ground-level vs elevated deck
- Site conditions (grading, demolition of old deck, etc.)
- Custom features such as railings, lighting, and stairs
A straightforward 12×20 Trex® Enhance® deck may cost $7,200 to $10,000 installed, while a custom Trex® Transcend® deck with railings and built-in seating could exceed $15,000 to $20,000.
Cost Comparison: Trex® vs Wood
Wood decks are cheaper upfront, typically costing $15–$25 per sq ft installed. However, they require frequent staining, sealing, and repairs. Over 20 years, wood decks often cost more than Trex® once maintenance is factored in.
Feature | Trex® Composite Decking | Wood Decking |
Initial Cost | $30–$80 per sq ft installed | $15–$25 per sq ft installed |
Maintenance | Occasional cleaning only | Staining, sealing every 1–3 yrs |
Lifespan | 25–50 years | 10–15 years |
Warranty | 25–50 years | None |
Over time, Trex® is the more cost-effective option, despite higher upfront costs.
Factors That Affect Trex Deck Installation Cost
Several factors can raise or lower your final project cost:
- Deck Size: Larger decks require more material and labor.
- Product Line: Enhance® is cheapest, Select® is mid-range, Transcend® is premium.
- Design Complexity: Multi-level decks or curves increase costs.
- Railing Options: Railings cost $20–$250 per linear foot.
- Stairs: More stairs = more materials and labor.
- Permits: Building permits in North Carolina vary by county.
- Demolition: Removing an old deck adds to labor costs.
- Add-Ons: Lighting, seating, pergolas, or custom features raise the price.
Long-Term Value of Trex® Composite Decking
While Trex® costs more upfront, it is important to look at long-term value:
- Lower Maintenance Costs: No sealing or staining.
- Extended Lifespan: Lasts 2–3 times longer than wood.
- Better Resale Value: Buyers see Trex® as a premium feature.
- Warranty Protection: Peace of mind for decades.
In short, Trex® pays for itself over time.
DIY vs Professional Installation
Some homeowners consider taking the DIY route when building a Trex® deck because they want to save on labor costs. At first glance, it looks like an affordable option. However, building a composite deck is much more complex than laying boards on a frame. Mistakes during installation not only compromise the safety of the structure but can also void the Trex® warranty.
Common DIY Risks
- Improper Joist Spacing: Trex® requires specific joist spacing to prevent sagging. Incorrect spacing leads to uneven boards and unsafe walking surfaces.
- Ledger Attachment Errors: If the deck is attached to your home incorrectly, it can allow water intrusion or even lead to structural collapse.
- Wrong Fasteners: Using non-approved fasteners causes corrosion and weakens the structure, especially in North Carolina’s humid climate.
- Lack of Permits: DIY decks often skip proper permitting, which can lead to fines, failed inspections, or even removal orders.
- Hidden Costs: Many homeowners underestimate the cost of tools, hardware, and the time required, turning a “budget” project into a money pit.
Advantages of Professional Installation
Hiring licensed contractors familiar with North Carolina building codes guarantees:
- Code Compliance: Decks are built to local regulations and pass inspections.
- Structural Safety: Correct footing depth, load-bearing capacity, and framing ensure your deck is safe for decades.
- Warranty Coverage: Trex® warranties are only valid when installed per manufacturer guidelines. Professionals ensure compliance so your warranty stays intact.
- Quality Finish: A professional deck builder delivers consistent spacing, seamless railings, and the polished look homeowners want.
- Time Savings: Instead of weeks of trial and error, you get a completed deck in days.
