In Jacksonville and across NE Florida, a custom deck typically runs about $20 to $42 per square foot installed, so most homeowners spend roughly $6,000 to $17,000 for a standard deck. The exact number depends mostly on the decking material, the size of the deck, and your site. Jacksonville Deck Builders, a Coastal Outdoor Construction brand, has built 500+ decks across Duval, St. Johns, Nassau, and Clay counties since 2013.
- Pressure-treated wood is the most budget-friendly at $20 to $30 per square foot installed, while composite like Trex and MoistureShield is the highest tier at $28 to $42 per square foot.
- AZEK PVC and Ipe hardwood are premium materials we offer at a competitive $20 to $30 per square foot installed; pavers and aluminum are priced by the project.
- Every deck is built by a FL-licensed general contractor to the Florida wind code (130-150 mph in our region), and we do new builds and full replacements only.
Most custom decks in Jacksonville run somewhere between $20 and $42 per square foot installed. The wide range comes down to one thing: the material you pick. Pressure-treated wood sits at the low end, cedar in the middle, and composite or PVC at the top. Below is an honest breakdown so you can ballpark your project before anyone steps on your property.
| Decking material | Installed price per sq ft | Best for |
|---|---|---|
| Pressure-treated wood | $20-$30 | The most budget-friendly option for a classic wood deck |
| Composite (Trex & MoistureShield) | $28-$42 | Lowest-upkeep, longest-lasting decks; our highest tier |
| AZEK PVC & Ipe hardwood | $20-$30 | Premium materials at a competitive price |
| Pavers & aluminum | Priced by project | Custom ground-level patios and specialty builds |

Deck Cost by Material in Jacksonville
Material is the biggest single factor in your price. Here is what each one typically costs, installed, in our area.
Pressure-Treated Wood: ~$20 to $30 per sq ft
This is the most affordable way to get a real deck. Pressure-treated pine holds up well in Florida when it is built right. It does need upkeep over the years, and our service is new builds and full replacement, not maintenance. If you want the lowest entry price, this is it. See our wood decks page for more.
Cedar: ~$20 to $30 per sq ft
Cedar gives you a warm, natural look and a softer feel underfoot. We use cedar as deck flooring for homeowners who want real wood with more character than pine. It sits in the middle of the price range.
Composite (Trex, MoistureShield): ~$28 to $42 per sq ft
Composite is the most popular choice we install. The boards are made to resist Florida sun, moisture, and bugs, and they do not need staining or sealing. The price range is wide because the entry lines and the premium lines are very different products. Most homeowners land in the middle. Learn more on our composite decking page.
AZEK PVC: top of the composite range
AZEK is full PVC, not wood-composite. It is the most weather-resistant option we offer and it runs about 30 degrees cooler underfoot than dark composite, which matters a lot on a Jacksonville afternoon. It costs more, but for bare feet around a pool or a sunny back deck, it is worth a serious look.
What a 12x12 and a 14x16 Deck Usually Cost
Square-foot math is useful, but homeowners think in real sizes. Here is what common deck footprints tend to run.
- 12x12 deck (144 sq ft): commonly $2,900 to $6,000, depending on the material. Pressure-treated lands near the bottom; composite and AZEK push toward the top.
- 14x16 deck (224 sq ft): a larger, more usable footprint. As a rough guide, multiply the per-square-foot range for your material by 224. A mid-grade composite build, for example, sits well above the 12x12 numbers.
These are starting ranges for a straightforward build. Railings, height, and the other drivers below can move the final number.

The Real Cost Drivers
Two decks of the same size and material can still come in at different prices. These are the things that move the number, and a good builder will walk you through every one.
Size
Bigger decks cost more in total but often a little less per square foot, since some setup costs are fixed no matter the size.
Height off the ground
A low ground-level deck is simpler and cheaper. A raised deck needs taller posts, more framing, and stairs, which all add cost. An elevated pool deck or a second-story deck is more involved than a deck that sits a step off the patio.
Railings
Railing is one of the most underestimated line items. Plain wood railing is affordable. Composite, metal, or cable railing costs more, sometimes a lot more on a deck with a long perimeter.
Footings and permits
Florida is serious about wind. We engineer every deck to 130 to 150 mph wind codes with hurricane-rated metal connectors and concrete footings. That is not optional and it is part of doing this right. Permits in Duval, St. Johns, Nassau, and Clay counties carry fees and inspections, and we handle that paperwork for you.
Site access and demo
A flat, open backyard is easy to work in. A tight side yard, a steep slope, or a fenced lot with no gate access takes more time and labor. If you have an existing deck that needs to come out first, that is demolition and removal, which we do for free as part of a replacement.
Why an In-Home Estimate Beats an Online Guess
A lot of homeowners get a one-line "estimate" over the phone and assume it is the price. Then the number climbs once work starts. We do it differently.
We come out, measure, and listen to what you actually want. Then we put together a paid design plan so you can see your deck before we build it. That design fee is credited back to your project when you build with us. Once the design is set, you get a real estimate in writing, usually within about a week. No surprises mid-project.
That up-front clarity is the whole point. You know the number, you know the material, and you know the timeline before anyone picks up a saw.
