The first question almost every DFW homeowner asks me when they look at the calculator is which material they should actually pick. Almost always it’s a choice between pressure-treated — the North Texas budget default — and capped composite, which has become the standard upgrade for first-time builds since about 2020. The sticker prices look very different. The five-year cost of ownership, once you factor in 100-degree Augusts, is closer than most people expect.
I’ll walk through what each material actually costs at install in DFW in 2026, what you spend on it over the first five years, and which one wins on resale. Everything below is for an installed deck in the Dallas–Fort Worth metroplex; numbers are in USD before state sales tax.
What you actually pay at install
For a 14×16 (224 sq ft) deck with a 36″ aluminum railing on three sides and three steps to grade, installed in 2026 across DFW:
- Pressure-treated lumber:$7,200–$10,800. The variance is mostly board grade (premium kiln-dried vs standard green-treated) and the contractor’s margin.
- Capped composite (mid-tier — Trex Enhance, TimberTech Edge, Fiberon Sanctuary):$11,800–$16,800.
- Premium capped composite (Trex Transcend, TimberTech Legacy, Fiberon Concordia):$14,500–$20,400.
Pressure-treated undercuts mid-tier composite by roughly $4,000–$6,000 at install on this size of deck. The gap is real but the five-year math closes it more than you’d expect because of how North Texas weather treats PT.
The first five years: pressure-treated in DFW
PT lumber in North Texas takes a beating that PT in milder climates doesn’t. The combination of 100+ degree Augusts, humid summer thunderstorms, dry winters, and clay-soil movement under the footings makes the board surface check, twist, and grey faster here than anywhere outside the Gulf Coast. Realistic annual maintenance for a 224 sq ft PT deck in DFW:
- Year 1:Wait six months for the boards to dry (they’re shipped wet from the treatment process), then clean and apply a penetrating water-repellent stain in fall. ~$200–$340 DIY (cleaner, stain, two days of effort) or $650–$950 contracted.
- Years 2–5:Clean every spring; restain every 18 months because DFW UV burns through stain faster than northern climates. Annualized: $180–$320 DIY, $550–$900 contracted.
Add the install price and you’re looking at, very roughly:
- PT DIY-maintained 5-year cost: $8,000–$12,400 total.
- PT fully-contracted 5-year cost: $9,950–$15,300 total.
The DIY path is the only way PT stays meaningfully cheaper than composite, and it costs you about a weekend a year — usually in October, which is the only comfortable working weather in DFW for most of the calendar.
The first five years: composite
Composite’s pitch is that maintenance is essentially zero. That’s mostly true but not entirely, and the one thing it introduces in DFW is the heat-underfoot question. Realistic annual maintenance on a 224 sq ft capped composite deck:
- Year 1: Nothing. The boards arrive sealed and finished.
- Years 2–5: Spring rinse with a garden hose and a mild detergent; occasional touchup for berry or wine stains. $0 in materials. ~1 hour of effort.
- One-off:If a board ever needs replacement (rare on capped composite within five years), you’re looking at $80–$140 per board plus a couple of hours of labour. Match the original lot number if you can or expect a slight colour variation.
Composite 5-year cost: essentially equal to install. Mid-tier: $11,800–$16,800. Premium: $14,500–$20,400.
The Texas heat tax
Worth calling out separately: dark-colour composite boards run hotter than PT in DFW summer sun. By 2 PM in July, a black or espresso composite board can hit 165°F surface temperature; barefoot contact is uncomfortable within seconds. Light-tone composite (sand, weathered teak, beach dune) runs 20–30 degrees cooler than the dark options. PT in the same conditions runs in the 140s. PVC (Azek-tier) runs the coolest of any synthetic, usually 10–15 degrees below capped composite. None of this is a deal-breaker but it’s a real consideration for any DFW deck that’ll get afternoon sun — lean toward lighter composite colours or accept that the deck is a sandals-required space May through September.
Putting them side by side
Total 5-year cost of ownership for the same 14×16 deck:
- PT, DIY maintained: $8,000–$12,400
- PT, contractor maintained: $9,950–$15,300
- Mid-tier capped composite: $11,800–$16,800
- Premium capped composite: $14,500–$20,400
DIY PT wins on absolute cost, comfortably — and only if you actually do the maintenance. Contracted PT maintenance creeps right up against mid-tier composite over five years. Premium composite is more expensive than either PT path, but you get a 25- to 30-year warranty and the deck looks the same in year five as it did at install — which is not a claim PT can make in Texas heat.
Where each material wins
Pressure-treated wins on:
- The cost in year one.Real if you’re stretching to afford a deck at all and you’re prepared to do the maintenance work yourself.
- Repairability. A damaged PT board is a 20-minute fix with a saw, a screwdriver, and a $15 board from any DFW lumberyard.
- Heat underfoot. PT runs cooler than dark-tone composite in DFW summer sun. Not a huge gap, but real.
Composite wins on:
- Time saved. Five years of fall restaining and maintenance adds up. If your time is worth $30 an hour, composite starts to pay for itself by year four or five.
- Resale appeal.DFW real-estate listings disclose deck material; capped composite is treated as a value-add in a way PT isn’t.
- UV tolerance. DFW UV is brutal on stain finishes. Composite holds its colour through the full warranty window; stained PT needs refreshing every 18 months.
What I’d actually pick
For a primary deck off the kitchen on a home you’re planning to live in for more than five years, in DFW, in 2026, I’d pick mid-tier capped composite in a light or mid-tone colour. The five-year cost is within $1,500–$2,500 of contracted PT maintenance, the look-after-itself factor is real, and the resale story is cleaner. Texas heat punishes PT finishes hard enough that even diligent owners spend more time and money on the deck than they’d expect.
For a smaller secondary deck, a rental property, or a homeowner who genuinely enjoys the fall restaining ritual — PT still earns its place. Just budget for the maintenance honestly. The cheapest PT deck in DFW is the one where you never get around to restaining it, and that’s a deck that’ll grey out and check within three summers.
