Trex is a composite decking made from recycled wood and plastic. In Jacksonville, installed Trex runs about $28 to $42 per square foot, which makes composite the highest-priced decking tier we build. People pick it because it holds up well to our heat, sun, and humidity, and it never needs sanding, staining, or sealing.
- Installed cost: $28 to $42 per square foot (composite is our top tier).

Trex is a composite decking made from recycled wood fibers and plastic. In Jacksonville, installed Trex runs about $28 to $42 per square foot. That puts composite at the top of our pricing tiers, but a lot of Northeast Florida homeowners decide it is worth it. The boards stand up to our heat, sun, and humidity, and you never have to stain, sand, or seal them.
| Decking material | Installed cost (per sq ft) | Maintenance | Best for |
|---|---|---|---|
| Composite (Trex, MoistureShield) | $28–$42 (highest tier) | None — just rinse | No-maintenance, long-term value |
| AZEK PVC | $20–$30 | Very low | Premium material, stays cool |

| Pressure-treated wood | $20–$30 | Stain/seal every 1–2 years | Lowest upfront cost |
| Pavers / aluminum | Priced by project | Low | Patios / waterfront structures |
This guide breaks down what Trex actually costs here, how it handles the coastal climate, what colors look best, and what to ask before you build. Plain English, no sales pitch.
What Trex decking is
Trex boards are made from a mix of recycled wood and recycled plastic film. The good lines have a hard plastic shell wrapped around the core. That shell is what fights stains, fading, and moisture.
The result is a board that looks like wood from a few feet away but does not act like wood. It will not rot. It will not splinter. Bugs leave it alone. And you will never spend a Saturday sanding and re-staining it.
If you want to compare Trex against the other composite brands we install, our composite decking in Jacksonville page lays out the full lineup, including MoistureShield.
How Trex holds up in Northeast Florida
Our climate is hard on decks. Long hot summers, strong UV, heavy rain, and salt air near the coast all wear down a wood deck fast. Trex was built for exactly this kind of abuse.
Heat and sun
The capped surface resists fading, so the color stays close to what you picked for years. One honest note: dark composite boards get hot in direct Florida sun, just like any decking. If your deck bakes in the afternoon, lean toward lighter colors. They stay cooler underfoot.
Humidity and rain
Trex does not absorb water the way wood does, so it will not warp, cup, or rot when our summer storms roll through. That alone solves the biggest headache homeowners have with old wood decks here.
Coastal salt air
Near the beaches and the Intracoastal, salt air corrodes hardware and chews up untreated wood. Trex boards shrug off salt air. We pair them with coastal-rated, stainless or coated hardware so the whole structure lasts.
Wind
Northeast Florida sits in a high-wind zone, and the Florida Building Code requires decks to handle 130 to 150 mph winds depending on where you live. We build the framing and connections to meet that code. The Trex boards sit on top of a frame engineered to stay put.
What Trex costs in Jacksonville
Here is the part everyone wants. These are real installed prices for Northeast Florida, per square foot, including labor and materials.
Composite, which includes Trex and MoistureShield, is our most expensive decking. You are paying up front for a deck that costs almost nothing to maintain over its life. For a lot of homeowners, that math works out.

Trex vs. other decking options
Trex is great, but it is not the only good choice. Here is how it stacks up against the materials we build most.
Pressure-treated wood ($20 to $30/sq ft installed) is the budget pick. It costs less to install, but you will be staining and sealing it every year or two to keep it from graying and rotting. Over ten years, that upkeep adds up. See our wood decks in Jacksonville page for the full picture on real wood.
AZEK PVC and Ipe hardwood ($20 to $30/sq ft installed) are premium materials at a competitive price. AZEK is a pure-PVC board that stays cool and resists stains well. Ipe is a dense tropical hardwood that lasts for decades and looks stunning. Both land below composite on price while still giving you a high-end deck.
Pavers and aluminum are priced by the project, since the design drives the cost. Pavers suit ground-level patios. Aluminum suits docks and structures right on the water.
The short version: Trex is the no-maintenance choice, AZEK and Ipe are the premium-material values, and pressure-treated is the budget option you keep paying for in upkeep.
Trex colors and styles
Trex comes in a wide range of colors, from light gray driftwood tones to warm browns to deep espresso. For Florida homes, we usually steer people toward lighter and mid-tone boards. They stay cooler and they hide pollen and dust better, which matters a lot during our heavy pollen season.
You can also mix in a border board or a contrasting color for the stairs and edges. It is a small upgrade that makes a deck look custom instead of plain. We keep current-season Trex samples on hand so you can see the real boards in your own light before you decide.
How a Trex deck gets built
Knowing the steps helps you plan and ask the right questions.
- Free consultation and quote. We come out, measure, talk through how you use the space, and give you a clear installed price.
- Design and material selection. You pick your Trex color, railing, and layout. We finalize the plan.
- Permits. We pull the permits with your county so the build is fully legal and inspected.
- Build. We frame to Florida wind code, install the Trex boards, and finish the railings and stairs.
- Final walkthrough. We inspect everything with you and make sure you are happy before we call it done.
One thing to know up front: we do new builds and full deck replacements only. We do not do repair or maintenance visits. If your old deck is past saving, we replace it the right way.
Permits and code in NE Florida
Every new deck in Duval, St. Johns, Nassau, and Clay counties needs a permit and has to meet the Florida Building Code, including the wind requirements. This is not optional, and skipping it can cause problems when you sell your home. We handle the entire permit process for you, so you do not have to call the county or schedule inspections yourself.
