How Much Does a Trex Deck Cost? Complete 2026 Pricing Guide Per Square Foot, by Product Line & Installation
A Trex deck is an investment, and the first thing every homeowner wants to know is the price. The honest answer is that it depends, mostly on the product line you choose, the size of the deck, and how complex the design is. The good news is that those factors are predictable, so once you understand them, you can build a realistic budget before you ever call a contractor.
This guide breaks Trex pricing down per square foot, by product line, and by deck size, using current 2026 numbers. It also covers what drives the cost up, how Trex compares to wood over time, and the smartest ways to save. By the end, you will know roughly what your project should cost and where the money goes.
The Short Answer: Average Trex Deck Cost
Most Trex decks cost between $30 and $60 per square foot installed in 2026, including the boards, framing, fasteners, and labor. A typical mid-size Trex deck lands somewhere around $12,000 to $20,000. A small, simple deck in the entry-level line can come in under $10,000, while a large deck in the premium line with upgraded railing can climb past $30,000.

Those ranges are wide because no two decks are the same. The three biggest levers are the product line, the size, and the design. Let us look at each one.
One quick note on the numbers you will see online. A lot of low Trex prices floating around are material-only costs, which leave out the labor, the framing, and the permit. Those are the costs that turn a pile of boards into a finished deck, and they often double the material price. The ranges in this guide are installed costs, which is what you will actually pay a contractor.
Trex Cost by Product Line
The Trex line you choose is one of the biggest cost factors. Enhance is the entry-level, budget-friendly line. Select is the mid-range step up. Transcend is the premium flagship. The chart below shows typical installed costs per square foot for each.
| Trex line | Installed per sq ft | What you get |
|---|---|---|
| Enhance | $30 to $50 | The entry-level line. Lowest price, 25-year warranty, scalloped board. |
| Select | $35 to $55 | The mid-range pick. Full shell, more colors, 35-year warranty. |
| Transcend | $45 to $65+ | The premium flagship. Best looks and durability, 50-year warranty. |

If you are comparing contractor quotes, always check which Trex line each one specifies. A quote built on Enhance and a quote built on Transcend are not the same deck, even at the same size. Asking every bidder to price the same line is the only way to compare them fairly.
Within the Transcend family, the newer Lineage collection sits at the top of the range. It adds heat-mitigating technology that helps the boards stay cooler in direct sun, which is worth considering for a deck that bakes in the afternoon. Expect it to price near the high end of the Transcend range.
Trex Deck Cost by Size
Size is the other big lever. A larger deck needs more boards, more framing, and more labor. Here are realistic 2026 ballparks for common deck sizes in mid-range Trex, so you can match a number to the footprint you have in mind.
One thing to keep in mind is that smaller decks often cost more per square foot, because fixed costs like the permit, mobilization, and stairs do not shrink with the deck. A 20 by 20 deck spreads those costs over more square footage, so the price per foot drops even as the total rises.
Where Your Trex Budget Goes
It helps to know what you are actually paying for. People often see only the board price and get surprised by the total. In reality, the cost splits fairly evenly between materials and labor, with the rest going to extras.
On most builds, materials run a little under half the total, labor a little under half, and extras like railing, stairs, the permit, and demolition make up the rest. The boards alone cost about $5 to $15 per square foot, but installation, framing, and fasteners are what turn that into the full price. This is also why a complex design costs more, since angles, curves, and multiple levels all add labor hours.
Labor for composite is also a bit higher than for wood, because the boards call for precise spacing, hidden fasteners, and extra framing support. That is not wasted money. Correct installation is exactly what protects the look and keeps the Trex warranty valid, so the labor line is part of what you are buying.
What Drives Trex Deck Cost Up
Beyond line and size, a handful of choices and site conditions move the number. Knowing them helps you understand a quote and decide where to spend.
- Railing. One of the biggest add-ons. Composite railing runs roughly $50 to $120 per linear foot, and cable or glass systems cost more.
- Stairs. Labor-intensive and material-heavy. Each step adds cost, and a full staircase can add several hundred to a couple thousand dollars.
- Height and footings. A raised deck needs taller posts and deeper footings. In the Chicago area, footings must reach below the frost line, which adds digging and concrete.
- Tearing out an old deck. Demolition and hauling away an existing deck adds a few dollars per square foot before the new build even starts.
- Design complexity. Curves, diagonal or herringbone board patterns, picture-frame borders, and multiple levels all increase waste and labor.
- Permits. Most decks need a permit, which can run from around one hundred to several hundred dollars depending on your town.
Common Add-On Costs
These are the upgrades that most often get added to a base deck price. None are required, but each one changes the total, so it helps to know roughly what they run.
| Add-on | Typical cost | Notes |
|---|---|---|
| Composite railing | $50 to $120 / linear ft | Cable and glass railing cost more. |
| Stairs | $50 to $120 / step | A full staircase adds up quickly. |
| Hidden fasteners | $1 to $2 / sq ft | A clean, screw-free surface. |
| Deck lighting | $500 to $2,000 | Stair, post, and step lights. |
| Permit | $100 to $500+ | Varies by town and project size. |

Cost to Replace a Wood Deck with Trex
Many Trex projects are not new decks at all. They are wood decks being replaced with composite. If your existing frame is still solid, the crew can often reuse it and simply swap the old boards and railing for Trex, which keeps the cost down. If the framing is rotted or was not built to carry the slightly heavier composite boards, it has to be rebuilt, and that adds labor and lumber to the job.
As a rough guide, resurfacing an existing deck with Trex, meaning new boards and railing on a sound frame, costs less than a full tear-out and rebuild. A full replacement that includes new framing lands in the same range as a brand-new deck of the same size. The only way to know which camp your project falls into is to have a builder check the condition of the existing structure first.
Trex vs. Other Composite Brands on Price
Trex is not the only composite brand, and price is one reason it stays popular. At each tier, Trex tends to sit slightly below comparable premium brands like TimberTech and AZEK, while offering similar low-maintenance performance. PVC boards from those brands can cost more, especially at the high end. For most homeowners comparing composite options, Trex lands in the sweet spot of strong performance at a more approachable price, which is part of why it is the most widely chosen composite deck material in the country.
Is a Trex Deck Worth the Higher Cost?
Trex costs more than wood up front. The boards run two to three times the price of pressure-treated lumber, so the sticker shock is real. The case for Trex is what happens after the build. A wood deck needs staining or sealing every couple of years, plus board replacement as pieces warp or rot, and it still wears out in 10 to 15 years. A Trex deck skips all of that and lasts 25 to 50 years.
Over time, those maintenance costs close the gap. Most estimates put the break-even point where Trex becomes cheaper than wood at somewhere around year 8 to 12, depending on how diligently the wood deck is maintained. If you plan to stay in your home, Trex usually wins on total cost, not just on convenience.

How to Save on a Trex Deck
You can bring a Trex budget down without giving up the things that matter. The trick is to cut in the right places.
- Choose a simpler line. Enhance or Select gets you a real Trex deck for less than Transcend, with most of the same low-maintenance benefit.
- Keep the shape simple. A clean rectangle is far cheaper than curves, angles, or multiple levels, and it still looks great.
- Reuse solid framing. If your existing deck frame is sound, building on it instead of rebuilding saves on labor and lumber.
- Pick standard colors. Premium and exclusive colors add to the material cost. Standard tones cost less and still look sharp.
- Get three quotes. Prices vary between contractors. Comparing a few itemized quotes for the same line keeps everyone honest.
It also pays to know where to buy. Comparing board prices and lengths at local deck supply stores can help you understand the material side of a quote before you sign.

Does a Trex deck add value to my home?
A quality deck is one of the stronger home improvements for resale, and a low-maintenance composite deck appeals to buyers who do not want yearly upkeep. The durability and clean look both help when it is time to sell.
How can I get an accurate Trex deck price?
Use the ranges here to set a budget, then get written quotes from a few local builders. A quote factors in your exact size, line, railing, and site, which a general estimate cannot.
The Bottom Line
A Trex deck costs what it costs for clear reasons: the product line, the size, and the design.
