Buying decking involves weighing cost, longevity, and maintenance. The Trex versus Pressure-Treated Wood Cost comparison highlights how upfront price, per-square-foot pricing, and long-term expenses shape the final total. This guide uses practical USD ranges and clear assumptions to help a U.S. shopper budget accurately.
Assumptions: standard 500 sq ft deck, Midwest to Southeast labor, typical 1×6 boards, standard fasteners, 4–5 inch board widths, and normal access.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Material cost (per sq ft) | $2.50 | $5.00 | $7.50 | Trex vs pressure-treated wood pricing gap. |
| Total decking installed (500 sq ft) | $1,250 | $2,500 | $3,750 | Excludes framing and railing. |
| Labor (per sq ft) | $1.50 | $3.00 | $4.50 | Includes framing prep for PT and composite. |
| Delivery/Haul-away | $100 | $250 | $500 | Assumes typical supply drop and waste handling. |
| Maintenance (annual, per sq ft) | $0.10 | $0.25 | $0.50 | Sealing, staining, or cleaning for PT vs Trex. |
Trex versus Pressure-Treated Wood Cost per Square Foot
Material price per square foot is the single biggest difference in the upfront cost. Trex typically runs higher at $3.50–$7.50 per sq ft installed when including standard boards, hidden fasteners, and basic trimming. Pressure-treated wood commonly lands at $2.00–$4.50 per sq ft, with the potential for discounts on bulk orders. The gap reflects both the composite’s manufacturing and longer warranty versus the lower initial PT price.
Major cost components in a decking quote
Pricing is driven by materials, labor, and fasteners. The following table breaks out common cost components for both Trex and PT decks.
| Component | Trex (Low) | Trex (High) | PT (Low) | PT (High) |
|---|---|---|---|---|
| Materials | $2.50 | $5.50 | $1.80 | $3.50 |
| Labor | $1.50 | $4.00 | $1.20 | $2.80 |
| Hidden fasteners/trim | $0.30 | $1.00 | $0.20 | $0.50 |
| Delivery/Disposal | $60 | $180 | $60 | $180 |
| Sealing/Stain (optional) | $0 | $0.60 | $0 | $0.60 |
Key drivers that shift Trex and PT quotes
Board length and profile directly impact material waste and cost. Longer 12-foot boards reduce seams but increase waste for irregular shapes. For PT, choosing 5/4 nominal boards versus 2×6 boards changes both price and install complexity. A mid-scale project with clean lines and standard 1×6 boards typically leans toward Trex at the higher end, while a budget-friendly PT layout stays in the lower range.
Maintenance and long-term cost differences
Ongoing upkeep drives long-term value in pricing comparisons. Trex decks generally need less maintenance, with costs near $0.10–$0.50 per sq ft annually for basic cleaning and occasional resealing ideas (though Trex itself is often low-maintenance). Pressure-treated wood requires periodic sealing or staining every 1–3 years, adding $0.10–$0.30 per sq ft annually in maintenance costs. Over 15 years, this can narrow the initial material gap but not erase it entirely.
Regional price variations within the United States
Location matters for both materials and labor. West Coast markets can push Trex prices 10–20% higher than national averages due to supply and labor, while rural areas may see PT decks priced 5–15% below metro rates. For a 500 sq ft deck, expect Trex to land in the $2,250–$6,000 range depending on profile and region, versus PT’s $1,500–$3,750 range with standard installations.
Scenario: upgrading a typical suburban deck now vs planning a replacement later
Short-term choice affects a future budget cycle. If the plan is to maximize longevity with minimal maintenance, Trex will cost more upfront but may avoid reseal costs. A PT deck offers lower upfront price but higher long-term maintenance and replacement risk, especially in climates with heavy sun or moisture. A 20-year plan could show incremental maintenance costs that approach or exceed the Trex premium, depending on climate and care.
Ways to reduce costs without sacrificing stability
Scope control and material choices matter more than coupons. Choose standard 12-foot boards with hidden fasteners instead of premium profiles, and limit trims and decorative railings. Consider a PT base frame with a Trex surface in high-traffic zones to balance cost and durability. Scheduling work in mild months and bundling deliveries can shave delivery fees and labor surcharges.
Practical quote comparison: interpreting a real-world snapshot
Seeing actual numbers helps budget confidently. A mid-sized suburban deck project might present these example quotes: Trex decking at $4.50 per sq ft with $0.50 per sq ft annual maintenance after year one; PT decking at $2.80 per sq ft with $0.25 per sq ft annual maintenance and a one-time staining cost. For 500 sq ft, total installed costs could range $2,500–$6,000 for Trex and $1,600–$4,000 for PT, excluding railing and framing upgrades.
What to request in a contractor quote
Ask for itemized line items and ranges. Ensure the quote lists materials, labor hours, per-unit pricing, fasteners, delivery, and any optional maintenance packages. Request a scenario that includes a 1-year maintenance plan and a 15-year material warranty for Trex to compare against PT’s staining and sealing needs.
