For most Jacksonville homeowners, capped composite (like Trex or MoistureShield) is the best all-around deck material because it handles NE Florida's heat, humidity, salt air, and 130-150 mph wind code without the rot, splinters, or yearly sealing that wood needs. If budget is tight, pressure-treated wood is the cheapest way to get a deck. If you want a premium look at a competitive price, AZEK PVC and Ipe hardwood are strong picks.
- Composite (Trex/MoistureShield) runs $28-42 per sq ft installed and resists rot, mold, and insects in our humid coastal climate.
- Pressure-treated wood is the lowest-cost option at $20-30 per sq ft installed but needs regular cleaning and sealing.
- Every deck we build in Duval, St. Johns, Nassau, and Clay counties is engineered to meet Florida's 130-150 mph wind code.
The deck material you pick decides how much you spend, how much work you do later, and how long it lasts in Florida heat and humidity. For most Jacksonville homeowners it comes down to four choices: composite (Trex, MoistureShield), PVC (AZEK), pressure-treated wood, and hardwood flooring like Ipe or cedar. This guide breaks down each one in plain terms so you can match the material to your budget and how you use the space.
| Material | Installed cost (per sq ft) | Upkeep | Holds up in FL heat & salt air | Best for |
|---|---|---|---|---|
| Pressure-treated wood | $20-30 | High — clean and seal regularly | Good with maintenance | Tight budgets, simple builds |
| Composite (Trex / MoistureShield) | $28-42 | Low — wash occasionally | Excellent — resists rot, mold, insects | Most homeowners wanting low upkeep |
| AZEK PVC | $20-30 | Low — wash occasionally | Excellent — fully synthetic, moisture-proof | Premium look at a competitive price |
| Ipe hardwood | $20-30 | Medium — oil to keep color | Excellent — dense, naturally durable | Natural wood lovers wanting longevity |
| Pavers / aluminum | Priced by project | Low | Excellent | Custom and ground-level designs |
We have built decks across Jacksonville and NE Florida since 2013, and the questions are almost always the same: What holds up here? What will I have to maintain? And what does it really cost? Here is the honest answer.
Why deck material matters more in Jacksonville
Our climate is hard on a deck. Hot summers, high humidity, heavy rain, salt air near the coast, and the occasional hurricane wear materials down faster than they would up north. The wrong material can warp, gray out, grow mold, or rot in a few seasons. Two things matter most here:
- Moisture and mold resistance. Humidity and rain mean boards that hold water are a problem. Materials that shed water and resist mold last longer with less work.
- Heat underfoot. Dark boards get hot in direct Florida sun. If you go barefoot or have kids and pets, surface temperature is worth thinking about.
Composite decking (Trex, MoistureShield)
Composite is a blend of wood fibers and recycled plastic. It is the most popular choice for Jacksonville homeowners who want a deck that looks good and stays low-maintenance for decades.
Pros
- No staining, sealing, or refinishing. You clean it with soap and water.
- Strong mold, rot, and insect resistance, which matters a lot in our humidity.
- Holds its color and finish for years in the Florida sun.
Cons
- Higher upfront cost than wood.
- Darker boards can get warm in direct sun.
Cost: roughly $28 to $42 per square foot installed, depending on the line and design. Composite is a great fit for families who want to spend weekends on the deck, not working on it. See more on our composite decking in Jacksonville page.
PVC decking (AZEK)
PVC is all plastic, no wood fiber. It sits at the top end for performance and is the best pick if heat and moisture are your top concerns.
- Coolest underfoot. AZEK runs about 30 degrees cooler than dark composite, which is a real difference around a pool or on a sunny deck.
- Top-tier moisture resistance. Because there is no wood in it at all, it will not absorb water, rot, or feed mold.
- Lightweight and long-lasting, with a clean, consistent look.
The trade-off is price. PVC is usually the most expensive option, but for a pool deck in Jacksonville where bare feet and constant water are part of daily life, many homeowners feel it earns its cost.

Pressure-treated wood
Pressure-treated pine is the classic, budget-friendly deck board. It is treated to resist rot and insects, and it is what a lot of Jacksonville decks are still built from.
Pros
- Lowest upfront cost by a good margin.
- Easy to work with and widely available.
- Looks like real wood because it is real wood.
Cons
- Needs regular upkeep. In our climate that means cleaning and re-sealing every year or two to fight graying, splitting, and moisture.
- Shorter lifespan than composite or PVC if it is not kept up.
Cost: roughly $20 to $30 per square foot installed. If your budget is tight or you are comfortable maintaining the deck yourself, pressure-treated wood is a solid, honest choice. Learn more on our wood decks in Jacksonville page.
Hardwood flooring (Ipe and cedar)
For homeowners who want the warmth and grain of natural wood with more staying power than treated pine, Ipe and cedar are worth a look as deck flooring.
- Cedar is naturally resistant to rot and insects, smells great, and runs cooler than many materials. It still needs sealing to keep its color in the Florida sun. Roughly $20 to $30 per square foot installed.
- Ipe is a dense tropical hardwood that is extremely tough, beautiful, and long-lasting. It is the premium natural-wood option and is priced to match.
Both reward homeowners who love the look of real wood and do not mind some upkeep to keep it looking its best.
How to match the material to your budget and use
Here is the short version we give most homeowners:
- Lowest cost, do not mind upkeep: pressure-treated wood.
- Set-it-and-forget-it, family deck: composite (Trex, MoistureShield).
- Pool deck or you go barefoot a lot: PVC (AZEK), for the cooler surface and moisture resistance.
- Love the look of real wood: cedar or Ipe flooring.
A common 12x12 deck typically runs about $2,900 to $6,000 depending on the material you choose. Composite and PVC cost more upfront but save you years of staining and sealing, while wood saves money now and asks for more of your weekends later.
Repair vs. replace
If your current deck is sagging, rotting, or pulling away from the house, you may be weighing whether to fix it or start over. As a rule, once the structure or framing is compromised, a full replacement is the safer, longer-lasting move. We focus on new builds and complete deck replacements, engineered for the way Florida weather behaves.
Built for Florida weather
Whatever material you pick, the structure underneath matters just as much as the boards on top. We engineer every deck to Florida 130 to 150 mph wind codes, with hurricane-rated metal connectors and concrete footings. The boards are the part you see; the framing is the part that keeps your deck standing through storm season.
If you are also thinking about a covered space, a pergola in Jacksonville or a screened porch can extend how much you use the deck through our hot, rainy months.
