If you are pricing a deck in Dallas, the first numbers you see online rarely match the quotes you get. Some sites quote board prices, some quote installed prices, and some mix national and local data without saying so. This guide keeps them apart, labels every figure as Dallas or national, and names the source for each figure. If you want a builder to price your own yard, see our page on custom composite and wood decks from a Dallas deck builder.
How much does it cost to build a deck in Dallas in 2026 per square foot?
In Dallas, a new deck costs roughly $15 to $30 per square foot installed in pressure-treated wood and $25 to $50 per square foot in composite (Block Renovation, 2026 Dallas guide). Those are installed prices: boards, framing, hardware and labor together.
National figures sit in the same range. Fixr's national cost guide (2023) lists pressure-treated decks at $15 to $25 per square foot installed and composite at $28 to $40. Advantage Lumber, a decking retailer, puts a professionally built deck in 2026 at $25 to $60 per square foot installed nationally, or $8,000 to $14,000 for a typical project.
Dallas also comes in a little under the national average on full deck projects. In Remodeling's 2025 Cost vs Value report, a wood deck addition in Dallas cost $15,841 against $18,263 nationally, and a composite deck addition cost $23,519 against $25,096 nationally. The report does not publish the size of those decks, so treat them as typical project totals, not a per-foot price.
How much does composite decking installation cost per square foot in Dallas TX in 2026 (labor and materials)?
Composite decks in Dallas run $25 to $50 per square foot installed (Block Renovation, 2026 Dallas guide). The boards and framing are only part of that number. Labor, railing and stairs make up the rest.
Materials: what the boards and framing cost
Trex estimates the material cost of a composite deck at $15 to $30 per square foot, counting the substructure, decking, hardware and fasteners but not its top Signature line (Trex FAQ). Trex also says materials make up as much as one third of the total cost of a professionally installed deck. That is why a lumberyard quote and a builder quote for the same deck can be far apart.
Board line matters too. Advantage Lumber's 2026 retail prices for standard composite boards start around $2.30 per linear foot for Trex Enhance Basics, $4.45 for Trex Select, $7.15 for Trex Transcend and $9.96 for Trex Signature. TimberTech starts around $3.43 per linear foot for Prime+, $6.12 for Reserve and $7.36 for Legacy. Those are prices per linear foot of board, not per square foot of deck, and the retailer notes they are subject to change.
Labor: what the crew costs
Nationally, deck labor runs $10 to $35 per square foot depending on the material (Fixr, 2023), and Advantage Lumber puts it at $15 to $35 per square foot in 2026. Neither source gives a Dallas-only labor rate.
Installed: higher-end composite
Advantage Lumber's 2026 national guide puts a standard installed composite deck at $40 to $70 per square foot, and $70 to $100 or more once you add premium railing, lighting or custom stairs. It puts an installed Trex deck at $45 to $70 per square foot. Those national figures run above the Dallas range from Block Renovation, so ask any builder which board line and railing a quote assumes.
Pressure-treated wood vs composite: Dallas deck building cost and pricing side by side
Pressure-treated wood is the cheapest deck to build in Dallas, while composite costs more up front and needs less upkeep. The table puts the sourced numbers next to each other. Each column comes from a different source, so read across a row, not down a column.
| Material | Dallas installed, per sq ft (Block Renovation, 2026) | National installed, per sq ft (Fixr, 2023) | Boards only, per sq ft (Trex comparison) |
|---|---|---|---|
| Pressure-treated pine | $15 to $30 | $15 to $25 | $2.50 to $4.50 |
| Cedar | Not in the 2026 guide ($26 to $29 in a 2021 Dallas estimate from HomeBlue) | $19 to $29 | $8.50 to $20 |
| Composite | $25 to $50 | $28 to $40 | $4.60 to $13.60 (Trex composite) |
The gap between the last column and the first two is the materials-versus-installed difference. Board prices leave out framing, footings, fasteners, railing and labor.
Upkeep is where composite claws some of that back. Trex says a wood deck can cost up to $400 a year in stain and sealant, against as little as $10 a year for a Trex deck. That is the manufacturer's own claim. Block Renovation's Dallas guide also notes that composite handles UV better than wood, which matters in Texas sun.
Resale tells a different story. In Remodeling's 2025 Dallas data, the wood deck addition recouped 99.8% of its cost and the composite one 92.1% (see the resale section below). A full composite-vs-wood comparison for Texas heat is a topic of its own. If you are torn, a builder can price both on the same footprint.
What does a 12x12, 16x20 or 20x20 deck cost?
For every common size from 10x10 to 20x30 in pressure-treated, cedar and composite, see the full deck cost by size guide. The short version is below.
Size is the biggest driver of the total: a 12x12 deck runs a few thousand dollars, while a 20x20 can pass $20,000 nationally. Fixr's 2023 national guide gives these installed ranges across materials:
| Deck size | National installed range (Fixr, 2023) | Dallas pressure-treated (calculated from Block Renovation's $15 to $30) | Dallas composite (calculated from Block Renovation's $25 to $50) |
|---|---|---|---|
| 12x12 (144 sq ft) | $2,160 to $7,920 | Not calculated | Not calculated |
| 16x20 (320 sq ft) | $4,800 to $17,600 | Not calculated | Not calculated |
| 300 sq ft | Not listed | $4,500 to $9,000 | $7,500 to $15,000 |
| 20x20 (400 sq ft) | $6,000 to $22,000 | $6,000 to $12,000 | $10,000 to $20,000 |
The Dallas columns are simple multiplication: square footage times Block Renovation's 2026 Dallas per-foot range. They do not include railing, stairs or demolition, which are covered below. For comparison, Fixr puts a typical national deck project at $9,000 to $20,000, with a national average of $14,000.
What does an elevated deck with stairs cost?
A raised deck costs more per square foot than one at ground level, because it needs taller framing, railing and stairs. Block Renovation's Dallas guide notes that elevated decks cost more because of the framing, and that they are less common in DFW's generally flat terrain.
No source gives a Dallas-only price for elevated decks, so these figures are national. Fixr (2023) lists installed costs of $25 to $50 per square foot for a raised deck, $30 to $60 for a two-story deck and $30 to $75 for a multi-level deck. Stairs add $75 to $450 per stair with labor included, according to Fixr, and Advantage Lumber's 2026 guide puts them at $150 to $300 per step.
A raised deck also needs railing on every open edge, which is the next cost to plan for.
How much do railings, stairs and a cover add to a deck?
Railing is often the biggest add-on, and cable and glass cost several times more per foot than wood. Fixr's 2023 national guide lists installed railing at these prices per linear foot:
| Railing type | National installed, per linear foot (Fixr, 2023) |
|---|---|
| Wood | $30 to $50 |
| Metal | $45 to $85 |
| Composite | $80 to $165 |
| Cable | $115 to $175 |
| Glass | $140 to $210 |
Advantage Lumber's 2026 guide gives a lower general range of $20 to $50 per linear foot for railings, without breaking it out by type. Stairs, as above, run $75 to $450 per stair nationally (Fixr).
A roof over the deck changes the price most. Fixr lists covered decks at $40 to $100 per square foot installed nationally. If you want shade, you can add a pavilion or pergola over the deck as part of the same build. A covered structure also usually means a permit (see the permit section below).
Does Dallas heat and clay soil change the price of a deck?
Dallas sits on shrink-swell clay and gets full sun, so footings and board color matter more here than in many markets. The Blackland Prairie runs from north of Dallas to south of San Antonio, and its clays swell when wet and shrink and crack when dry. The Soil Science Society of America notes that construction on this soil is often plagued by cracking. For a deck, that makes the footings and posts the part not to skimp on.
No source puts a dollar figure on what clay soil adds to a Dallas deck, so be wary of any quote that adds a vague "soil fee" without explaining the footing plan.
Heat is the other local factor. Trex says composite gets hot in direct sun, and the darker the color, the hotter the deck will feel. It suggests lighter colors or its SunComfortable boards in hot climates. Composite does handle UV better than wood, according to Block Renovation.
Do you need a permit for a deck in Dallas, and what does it cost?
Covered structures and elevated decks typically need a permit. The City of Dallas permit fee schedule (effective July 1, 2025) has no flat deck fee: a residential permit carries a plan review fee of $0.046 per square foot or $577, whichever is greater, plus a base permit fee and a $125 inspection fee per trade. Ask the City of Dallas or your builder before you budget. Nationally, Fixr says a deck permit starts at $100 to $500, depending on the area.
Suburbs set their own fees and rules, so the answer differs in Plano, Frisco, McKinney, Richardson, Garland and Rockwall from Dallas itself. If you have an HOA, check it too. Block Renovation notes that HOA rules commonly cap the height of patio covers and pergolas and require setbacks, often 5 to 15 feet from rear and side boundaries.
Does a deck pay for itself at resale in Dallas?
In Remodeling's 2025 Dallas data, a wood deck recouped 99.8% of its cost and a composite deck recouped 92.1%. The wood deck addition cost $15,841 and added $15,813 in resale value. The composite deck addition cost $23,519 and added $21,658.
Both beat the national figures in the same report, where a wood deck recouped 94.9% and a composite deck 88.5%. One caution from Block Renovation's Dallas guide: the outdoor projects that underperform at resale are typically the ones overbuilt for the neighborhood. Build for how you will use the deck, sized to fit the house.
How do you choose the best deck builder in Dallas TX? (reviews, portfolio, licensed and insured)
Texas does not require general contractors to be licensed or bonded at the state level, so check insurance, references and finished work yourself, and get the price in writing. Our full guide, how to choose a deck builder in Dallas, covers Dallas contractor registration, insurance checks, the questions to ask and what a written deck quote should include. You can see finished Archetex decks and patios on our work page.
How to get an accurate deck quote in Dallas
Get every quote for the same scope (size, board line, railing, stairs and demolition) so the numbers actually compare. Small differences in those choices move the price a lot. A cable railing can cost several times more per foot than wood, and stairs run $75 to $450 per stair nationally (Fixr, 2023). Composite boards range from about $2.30 to $9.96 per linear foot across the Trex lines, by Advantage Lumber's 2026 retail prices.
If an old deck is coming out first, budget for that too. Fixr's national guide says tearing out an old deck adds $5 to $15 per square foot.
Before you call anyone, write down:
- The rough size, or the space you want to fill.
- Ground level or raised, and how many steps down to the yard.
- Wood or composite, and whether you want to see both priced.
- The railing style you like.
- Whether you want shade now or later.
- Whether an old deck or patio has to come out.
Archetex does not publish set prices, because the yard, height and materials change every job. Matthew gives a free site visit and a written price. If the deck is one piece of a bigger plan, we can also plan the deck as part of a full outdoor living space. You can contact us to book a visit, or start on the Dallas deck builder page.
