Deck Installation Cost Per Square Foot in 2026
Deck installation cost per square foot in 2026 runs $25–$70 installed for a typical professionally built deck, depending on the decking material. Pressure-treated wood anchors the low end at $25–$40 per sq ft, cedar and redwood sit in the middle at $35–$50, composite runs $40–$60, and PVC tops the common range at $50–$70. Premium hardwoods like ipe can reach $60–$80 per sq ft installed. These per-foot figures cover the complete deck — framing, boards, footings, fasteners, and labor — not just the boards.
Quick-answer table (typical 2026 deck installation cost per square foot, professionally installed):
| Material | Per sq ft (installed) | 200 sq ft deck | 400 sq ft deck |
|---|---|---|---|
| Pressure-treated wood | $25–$40 | $5,000–$8,000 | $10,000–$16,000 |
| Cedar / redwood | $35–$50 | $7,000–$10,000 | $14,000–$20,000 |
| Composite | $40–$60 | $8,000–$12,000 | $16,000–$24,000 |
| PVC | $50–$70 | $10,000–$14,000 | $20,000–$28,000 |
| Ipe (Brazilian hardwood) | $60–$80 | $12,000–$16,000 | $24,000–$32,000 |
The per-foot rate is the fastest way to sanity-check a contractor quote: multiply the quoted rate by your deck’s square footage and compare it against these ranges. If a quote lands far outside, ask exactly what is included — railings, stairs, and permits are the usual gaps. For worked examples at common sizes, see our guides to how much a 20×20 deck costs and how much it costs to install a 12×12 deck.
Deck Installation Cost Per Square Foot by Material
| Material | Materials only / sq ft | Labor / sq ft | Installed total / sq ft | Lifespan |
|---|---|---|---|---|
| Pressure-treated wood | $8–$12 | $8–$15 | $25–$40 | 10–15 years |
| Cedar / redwood | $12–$20 | $8–$15 | $35–$50 | 15–20 years |
| Composite | $15–$28 | $8–$15 | $40–$60 | 25–30+ years |
| PVC | $20–$35 | $8–$15 | $50–$70 | 30–50 years |
| Ipe | $24–$40 | $12–$20 | $60–$80 | 40–75 years |
Note that materials-plus-labor alone does not add up to the installed total: footings, railings, stairs, fasteners, permits, and contractor overhead make up the difference. That is why a boards-only price from a home-improvement store always looks far cheaper than a real quote — it leaves out half the project.
Pressure-treated wood at $25–$40 per sq ft is the budget benchmark, but add maintenance: staining and sealing every 1–2 years runs roughly $1–$2 per sq ft per treatment, which adds $400–$800 over a decade on a 200-square-foot deck.
Composite at $40–$60 per sq ft costs more upfront but needs only soap-and-water cleaning, and most capped-composite lines carry 25-year warranties. PVC at $50–$70 per sq ft is the longest-lived synthetic option and holds color best, though it can feel hot underfoot in direct sun. Ipe at $60–$80 per sq ft reflects specialist labor — the dense hardwood needs pre-drilling and stainless fasteners — plus a 40+ year lifespan.
What’s Included in the Per-Square-Foot Price
A legitimate per-square-foot quote should cover the complete structure. Here is how the $25–$70 per sq ft installed range typically breaks down on a mid-range composite deck:
| Component | Share of per-sq-ft price | Notes |
|---|---|---|
| Decking boards | $15–$28 | Depends on material |
| Framing (joists, beams, posts) | $4–$8 | Pressure-treated; steel framing costs more |
| Footings / concrete | $2–$5 | Deeper footings in cold climates (frost line) |
| Fasteners, hardware, flashing | $1–$3 | Hidden fasteners at the high end |
| Labor | $8–$15 | Framing, decking, railing, stairs |
| Railings (amortized) | $3–$10 | Wood at the low end, cable/glass at the high end |
| Stairs (amortized) | $1–$5 | Depends on runs and height |
| Permits, overhead, profit | $3–$8 | Contractor’s business costs |
If a quote is dramatically below these ranges — say $15 per sq ft installed — something is missing. Common omissions: railings, stairs, permits, old-deck removal, and cleanup. Always ask for an itemized quote and confirm the scope in writing before comparing per-foot rates.
Cost Drivers That Push the Per-Foot Price Up
| Driver | Effect on per-sq-ft price | Notes |
|---|---|---|
| Deck height | +$5–$25 | Second-story decks need taller posts, bigger footings, longer stairs |
| Shape and levels | +$5–$15 | Multi-level, curved, or angled designs add labor and waste |
| Railings | +$3–$15 | Glass or cable railings cost far more than wood |
| Stairs | +$1–$5 amortized | Each extra run adds structure and railing |
| Site conditions | +$2–$8 | Slope, rock, poor drainage, tight access |
| Old deck removal | +$2–$4 amortized | Haul-away and disposal |
| Small deck size | +$3–$8 | Fixed costs (permits, mobilization) spread over fewer sq ft |
| Local labor market | ±25% | Metro and coastal markets run higher |
Two effects surprise homeowners most. First, small decks cost more per square foot than large ones: a 12×12 deck carries the same permit, mobilization, and stair costs as a much bigger deck, spread over 144 square feet instead of 400. Second, height is expensive: a second-story deck can cost 20–60% more per square foot than the same deck at ground level.

Deck Installation Cost Per Square Foot: DIY vs Hiring a Pro
| Factor | DIY (materials only) | Professional (installed) |
|---|---|---|
| Pressure-treated wood | $12–$20 per sq ft | $25–$40 per sq ft |
| Composite | $20–$35 per sq ft | $40–$60 per sq ft |
| PVC | $28–$45 per sq ft | $50–$70 per sq ft |
| Labor saved | Your time (6–10 hrs per 100 sq ft) | — |
| Permits / inspection | You handle it | Usually handled for you |
| Risk | Footing, ledger, and joist mistakes are structural | Licensed, insured, warranty-backed |
| Best for | Ground-level wood decks, experienced DIYers | Elevated decks, composite/PVC, tight timelines |
DIY saves the labor portion — roughly $8–$15 per sq ft — plus some overhead, but you still pay for boards, framing, footings, fasteners, railings, and stairs, and you need tools (a miter saw, impact driver, post-hole digger or auger, and a level at minimum). On a 200-square-foot pressure-treated deck, DIY typically runs $2,400–$4,000 in materials versus $5,000–$8,000 installed. The savings are real, but the ledger board connection to the house and the footing depth have to meet local code — get the plans and permit approved first and have the framing inspected before you lay boards.
Money-Saving Tips
- Keep the shape simple. A plain rectangle costs less per square foot than an L-shape or multi-level design — fewer cuts, less waste, faster labor.
- Compare per-foot quotes on equal scope. Two quotes at $45 and $55 per sq ft are not comparable if one includes railings and stairs and the other does not — demand itemization.
- Choose entry-level capped composite. At $40–$50/sq ft installed, it delivers the low-maintenance benefit without the premium-line price.
- Build in the off-season. Late fall and winter bookings run 10–15% lower than spring in most markets.
- Do the demo yourself. Tearing out an old deck saves roughly $2–$4 per sq ft in removal and disposal.
- Skip the extras for now. Built-in seating, lighting, and planters can be added later without re-doing the structure.
- Order 10% extra material. Waste from cuts runs about 10%; a mid-project lumber run costs time and delivery fees.
Frequently Asked Questions
What is the average deck installation cost per square foot?
The average deck installation cost is $25–$70 per square foot installed in 2026, depending on material: pressure-treated wood $25–$40, cedar/redwood $35–$50, composite $40–$60, PVC $50–$70, and ipe $60–$80. A typical 200-square-foot deck therefore runs $5,000–$14,000 depending on material.
How much does a 200 sq ft deck cost?
A 200-square-foot deck costs roughly $5,000–$8,000 in pressure-treated wood, $7,000–$10,000 in cedar, $8,000–$12,000 in composite, and $10,000–$14,000 in PVC. Add $500–$1,500 if an old deck must be removed first.
Does the per-square-foot price include railings and stairs?
A complete per-square-foot quote should include basic railings and one stair run, but not every quote does. Railings alone can add $3–$10 per sq ft amortized across the deck, and stairs $1–$5 per sq ft. Always confirm in writing what the per-foot rate covers before comparing bids.
Why do per-square-foot deck prices vary so much?
Material is the biggest factor (a $15 per sq ft spread from wood to PVC), followed by deck height, shape complexity, railing choice, site conditions, and local labor rates. Small decks also run higher per square foot because fixed costs spread over fewer square feet.
How much does labor cost per square foot for a deck?
Deck installation labor typically costs $8–$15 per square foot for a straightforward build, or roughly 30–40% of the installed total. Complex, elevated, or multi-level decks push labor toward the high end; simple ground-level rectangles sit at the low end.
The Bottom Line
Deck installation costs $25–$70 per square foot installed in 2026 — pressure-treated wood at $25–$40 for budget builds, composite at $40–$60 as the best value for most homeowners, and PVC at $50–$70 for maximum lifespan and minimum maintenance. Use the per-foot rate to sanity-check quotes, but always compare itemized all-in totals: a low per-foot rate that excludes railings, stairs, and permits is not a bargain. Get three written, itemized quotes and pick based on total scope — not the headline number.
Prices are typical 2026 US ranges gathered from contractor pricing data, manufacturer list prices, and industry sources; your actual cost depends on decking material, deck height and shape, railings, stairs, site conditions, old-deck removal, permits, and regional labor rates. Always get at least three written, itemized quotes from licensed, insured contractors before committing.
