Wood is cheaper on day one. That is the entire case for wood in 2026. Every other line of the comparison — lifespan, maintenance, warranty, structural integrity at year ten, resale value, color stability — favors composite, and in Utah's climate the gap is wider than almost anywhere else in the country. This is the comparison we walk every Wasatch Front homeowner through before they sign a contract.
We build both. About 92% of our 2025 builds were Trex composite, but we still do pressure-treated and cedar for the right homeowner. Here is when each one actually makes sense.
What Utah's climate does to a deck
Utah is one of the harshest deck climates in the lower 48. We average 120+ freeze-thaw cycles a year along the Wasatch Front — water gets into a board, freezes overnight, expands roughly 9%, then thaws by noon and the cycle repeats. We also get extreme UV at altitude (Salt Lake sits at 4,200+ feet, Park City at 7,000), low humidity that pulls moisture out of wood fibers, and snow loads that sit on the deck surface for weeks at a time.
Pressure-treated southern yellow pine — the cheapest and most common Utah deck wood — is designed for the southeastern US, not for high-altitude freeze-thaw. Cedar holds up better but splits under the same UV and snow conditions. Composite is unaffected by all of it.
Realistic lifespan, side by side
| Material | Surface life | Structural life | Maintenance |
|---|---|---|---|
| Pressure-treated pine | 5–8 years | 12–15 years | Stain every 2–3 years |
| Western red cedar | 8–12 years | 15–20 years | Stain every 2–4 years |
| Ipe / tropical hardwood | 20–30 years | 30+ years | Oil annually |
| Trex Enhance | 25–30 years | Same as framing | Wash twice a year |
| Trex Select | 30–40 years | Same as framing | Wash twice a year |
| Trex Transcend | 40–50+ years | Same as framing | Wash twice a year |
"Surface life" is when the boards start to splinter, cup, or look bad enough to replace. "Structural life" is when the joists, beams, and ledger need significant work. The two are decoupled on composite because the boards outlast almost any reasonable framing — which is why we over-engineer composite framing as if it has to last 50 years, because it does.
True 20-year cost of ownership
Comparing a wood deck to a composite deck on day one is the wrong math. The right math is the 20-year total: build cost plus maintenance plus repairs plus eventual replacement. Here is what a typical 14×20 deck actually costs over 20 years in Utah.
| Cost line | PT wood | Cedar | Trex Select |
|---|---|---|---|
| Initial build (2026) | $12,500 | $17,000 | $24,000 |
| Staining (every 2.5 yrs avg, $1,400/cycle) | $11,200 | $11,200 | $0 |
| Board replacement at year 7 (~30% of boards) | $3,200 | $2,400 | $0 |
| Full structural rebuild at year 14 | $11,500 | $13,000 | $0 |
| 20-year total | $38,400 | $43,600 | $24,000 |
Wood is roughly 60% more expensive than composite over 20 years in Utah, and the wood deck spends most of those years looking worse. The case for composite is the cost case, not just the looks case.
When wood still makes sense
We are not anti-wood. There are three scenarios where we will recommend it:
- Rental properties you plan to sell inside 5 years. The lower upfront cost matters more than the 20-year math.
- Historic homes where composite would look out of place. A craftsman bungalow in the Avenues often deserves cedar, period.
- Homeowners who genuinely enjoy maintaining a deck. A few of our clients love the annual stain cycle. If that's you, cedar will outlive pressure-treated by years.
Three myths about composite we hear every week
Myth 1: "Composite gets too hot to walk on." Modern Trex (Enhance gen 2 and up) runs 5–8°F cooler than the old generation. On a 95°F Utah afternoon a dark composite board is still hot, but it is no hotter than a stained dark wood board in the same sun. Lighter color choices solve the problem entirely.
Myth 2: "Composite looks fake." True of 2008 composite. Not true of 2025 Trex Select or Transcend. We have a sample board kit in the truck — half the homeowners on our site walks cannot tell which sample is composite and which is hardwood until we point it out.
Myth 3: "Composite is bad for resale." Wasatch Front MLS data from the last 36 months shows the opposite — homes with composite decks under 10 years old sell 4–11 days faster than comparable homes with wood decks, and appraisers consistently assign higher contributory value to composite. Buyers do not want to inherit a stain schedule.
- Utah's 120+ annual freeze-thaw cycles destroy pressure-treated wood at the 12–15 year mark.
- Trex composite costs roughly 40% less than wood over a 20-year ownership window in Utah.
- Composite is the right call for almost every primary-residence build along the Wasatch Front.
- Wood still makes sense for short-hold rentals, historic homes, and owners who actually enjoy maintenance.
Frequently asked questions
+Does Trex really hold up in Utah's cold winters?
Yes. Trex is rated and warrantied for freeze-thaw climates and we have decks in our portfolio built in 2015 that still look new after ten Utah winters with zero structural or surface issues. Snow can sit on Trex indefinitely without causing damage.
+How often does a wood deck need to be re-stained in Utah?
Every 2–3 years for pressure-treated pine, every 2–4 years for cedar. Utah's UV at altitude is brutal on stain, and most homeowners we meet have let the cycle slip to 4–5 years by accident — which is when the boards start to crack and gray out permanently.
+Will composite decking fade in Utah's sun?
Modern Trex (2018 and later) fades roughly 5% in the first 12–18 months as the surface settles, then is essentially color-stable for the rest of its life. The 25/50-year warranty explicitly covers fading and staining.
