For most Jacksonville and NE Florida homes, Trex and MoistureShield composite are the best all-around picks — both are wood-plastic boards built to shrug off our heat, humidity, and salt air, and Jacksonville Deck Builders is an authorized contractor for both. AZEK is a solid PVC alternative if you want the lightest, fully synthetic board. Here is how to choose:
- Trex or MoistureShield composite — best for buyers who want a proven, low-maintenance deck and don't mind the highest material cost ($28-42 installed per sq ft).
- AZEK PVC — a fully synthetic, lighter board offered as a premium material at a competitive price ($20-30 installed per sq ft).
- All three resist rot, moisture, and fading better than wood, and all can be built to meet Florida's 130-150 mph wind code across Duval, St. Johns, Nassau, and Clay counties.
For most Jacksonville homes, the best low-maintenance deck comes down to your budget. Trex and MoistureShield are both solid, mid-priced composite boards that handle our heat and humidity well. AZEK is full PVC, sits in the premium material, and stays the coolest underfoot, which makes it a favorite for pool decks and sunny backyards.

The quick version
All three brands give you a deck you do not have to stain, sand, or seal. That is the whole point of going low-maintenance in Florida. Here is the short take on each:
- Trex — A capped composite. Wood fibers wrapped in a tough plastic shell. Great looks, strong warranty, fair price. We are an authorized Trex contractor.
- MoistureShield — Also a capped composite, but the core is built to handle water and even ground contact. A smart pick near the river, the marsh, or low spots. We are an authorized MoistureShield contractor too.
- AZEK — Full PVC. No wood at all. The lightest, coolest, and most weather-resistant of the three. It is premium, and it costs the most.
What "composite" really means
Composite decking is a board made from a mix of recycled wood and plastic, then wrapped in a hard outer layer. That wrap is what fights stains, fading, and scratches. Trex and MoistureShield both work this way.
AZEK is different. It has no wood inside at all. It is solid PVC, which is the same family of plastic used in piping. That is why people group all three together when they shop, even though AZEK is technically its own thing. If you want a deeper walk-through of how these boards are built, see our composite decking in Jacksonville page.
Heat: which one is coolest underfoot?
This matters a lot here. A dark deck in full Florida sun can get hot on bare feet. AZEK runs the coolest of the three because PVC holds less heat than wood-plastic blends. Trex and MoistureShield both offer lighter colors and heat-reducing lines that help a lot too.
The simple rule: lighter colors stay cooler, no matter the brand. If your deck bakes in the afternoon sun in Mandarin or Nocatee, go lighter, or step up to AZEK.
Water and humidity
We live in a wet, salty place. Storms, humidity, and sprinklers all test a deck. All three brands shrug off normal rain and moisture far better than real wood.
MoistureShield has an edge in the wettest spots. Its core is rated for tough, damp conditions, so it is a strong choice for waterfront homes, shaded yards that stay damp, or anything close to the marsh. AZEK, being solid PVC, also does not absorb water. Trex handles humidity well with its capped shell.
Around a pool, water and heat both come into play. That is why we often steer pool clients toward AZEK or a lighter composite. You can read more on our pool decks in Jacksonville page.
Looks
All three have come a long way. You can get rich wood-grain looks, gray driftwood tones, and warm browns in every brand. AZEK tends to have the most realistic grain and the widest premium color range. Trex and MoistureShield both look great and offer plenty of colors most homeowners love.
Honestly, in a side-by-side on a finished deck, most people cannot tell which brand they are standing on. Color choice matters more than brand here.

Wind and our building code
Florida wind code in our area runs 130 to 150 mph depending on your exact location. A deck is only as strong as its frame and fasteners, not just the boards on top. As a licensed Florida general contractor, we build every deck to meet local code and pull the right permits. That is true whether you pick Trex, MoistureShield, AZEK, or a wood deck.
Cost: what you will actually pay
Here are honest installed ranges for Northeast Florida. These cover materials and labor, per square foot:
- Pressure-treated pine — about $20 to $30. The budget option. It needs regular sealing and will not last as long.
- Composite (Trex and MoistureShield) — about $28 to $42. The sweet spot for most homeowners. Low upkeep, long warranties, great value.
- AZEK PVC and Ipe hardwood — the premium material, at a competitive $20–30 per sq ft. AZEK for the best PVC performance, Ipe for a true hardwood look.
Your real number depends on deck size, height, railings, stairs, and site access. Two decks of the same size can price differently. That is why a quote off the internet is never accurate. Our free in-home estimate gives you a real estimate, not a guess.

So which composite is best?
There is no single winner. It depends on you:
- Pick Trex if you want a trusted, mid-priced composite with strong looks and a great warranty.
- Pick MoistureShield if your yard stays wet, you are near the water, or you want a core built for tough, damp conditions.
- Pick AZEK if you want the coolest, lightest, most weather-resistant board and you have room in the budget for the premium material.
Any of the three will outlast and out-perform a wood deck with far less work. The best choice is the one that fits your yard, your sun, and your budget. We will help you sort that out in person.
