How Much Does a Deck Installation Cost? A Complete 2026 Breakdown
Most homeowners ask one question before signing a contract: how much does a deck installation cost? The honest answer is that it depends on the size of the deck, the material you choose, and where you live. Across the United States, a professionally built deck typically runs between $15 and $40 per square foot, including labor, which puts the majority of projects somewhere between $4,000 and $15,000.
On average, homeowners spent roughly $7,800 to have a standard 350-square-foot pressure-treated wood deck built in 2025, according to cost data compiled by Angi and HomeAdvisor. Composite and PVC decks run higher upfront, often $30 to $60 per square foot, but demand far less sanding, staining, and sealing over the decades you own them.
The range is wide because no two decks are alike. A 10-by-12 ground-level platform with no stairs sits at the bottom of the scale; a 16-by-20 multi-level deck with stairs, railing, built-in benches, and a weatherproof covering sits near the top. This guide breaks the numbers down by material, size, and labor so you can price your project realistically and recognize a lowball bid before it becomes a headache.
Average Deck Installation Costs at a Glance
Before choosing materials, it helps to know the overall shape of the market. The figures below reflect total project cost, including both materials and labor, for a typical residential deck in the continental U.S.
| Deck Type | Cost Per Sq Ft | Average Total for 350 Sq Ft |
|---|---|---|
| Pressure-treated pine | $15–$25 | $5,250–$8,750 |
| Cedar / redwood | $25–$40 | $8,750–$14,000 |
| Composite (Trex, TimberTech) | $30–$60 | $10,500–$21,000 |
| PVC / capped polymer (Azek) | $35–$70 | $12,250–$24,500 |
| Tropical hardwood (ipe, cumaru) | $40–$80 | $14,000–$28,000 |
Wood is the cheapest to buy but the dearest to keep. Composite and PVC flip that equation: you pay more now and less every spring for the rest of the deck’s life.
How Much Does a Deck Installation Cost by Material?
The single biggest pricing lever is the decking board itself. Here’s what each option actually costs, including hidden expenses like fasteners, sealers, and long-term upkeep.
Pressure-Treated Pine ($15–$25 per sq ft)
Pressure-treated southern yellow pine is the workhorse of American decks. It resists rot and insects, goes in quickly, and keeps a 300-square-foot deck under $6,000 in most markets. The trade-off is maintenance: you’ll restain or reseal it every two to three years, and it’s prone to warping and splintering as it dries.
Cedar and Redwood ($25–$40 per sq ft)
Cedar and redwood cost more but offer a warmer, premium look and stronger natural rot resistance. They’re softer than composite, so a dropped grill or a dog’s claws will leave marks. Expect to seal them annually to keep the color from fading to gray.
Composite and PVC ($30–$70 per sq ft)
Composite boards from brands like Trex and TimberTech blend recycled wood fibers with plastic; PVC boards such as Azek are pure polymer. Both shrug off stains, fading, and mold, and neither needs sanding or sealing. Installers often charge slightly more for composite because it demands specific fastening systems and careful gapping for expansion. If you plan to stay in the home ten years or more, this is usually the better value.
Hardwood ($40–$80 per sq ft)
Ipe, cumaru, and other tropical hardwoods are gorgeous and incredibly dense; ipe can last 40 years or more. But that density is also why installers quote a premium: the boards dull saw blades and require pre-drilling for screws. Hardwood is best reserved for smaller, high-visibility decks.
What Drives the Final Price?
Material is only part of the story. These five factors move a quote more than most homeowners expect.
Deck Size and Footprint
A bigger deck means more boards, more joists, more footings, and more days on site. A 12-by-12 deck (144 square feet) might cost $3,000 to $6,000 in pressure-treated pine, while a 16-by-20 deck (320 square feet) can pass $10,000 in the same material. If you want to price a specific footprint, our guide to how much a 12×12 deck costs walks through the math.
Height and Foundation Work
A ground-level deck skips stairs and tall posts, which keeps the job fast. Anything raised more than a few feet needs footings dug below the frost line, posts, beams, and often a permit plus an inspection. Ledger-board attachment to the house, flashing, and waterproofing all add labor hours.
Railings, Stairs, and Built-Ins
The decking boards are the cheap part; the framing and finishing are where money hides. Railings, especially aluminum or cable systems, run $25 to $75 per linear foot on their own; see our breakdown of deck railing cost per foot. Stairs, benches, planters, and a pergola each add a line item.
Labor Rates in Your Area
Labor accounts for roughly 50% to 65% of most deck quotes. In high-cost metro areas, experienced deck builders charge $35 to $50 per hour or more, while rural markets run closer to $20 to $35. A complex composite deck can take a two-person crew two to three weeks; a simple pine platform can be done in four to six days.
Permits and Site Prep
Most municipalities require a permit for an attached or raised deck, typically $150 to $500. Tearing out an old deck, leveling a sloped yard, or removing tree roots pushes the price further. Always ask whether the quote includes demolition, haul-away, and permit fees.
Labor vs. Materials: Where the Money Goes
Roughly half to two-thirds of a deck budget is labor, which surprises first-time buyers who assume the boards dominate the invoice. Here’s how a $10,000 composite deck typically splits:
- Decking and railing materials: $3,800–$4,500
- Framing lumber, footings, and hardware: $1,200–$1,800
- Labor (framing, install, cleanup): $4,000–$5,000
- Permit and site prep: $300–$800
That split explains why the cheapest bid is rarely the best deal. A contractor quoting material-only prices on labor is either underpaying a crew or planning to skip steps like flashing and proper joist spacing.
Wood vs. Composite: Total Cost Over Time
The sticker price isn’t the real cost. Over a 20-year span, the maintenance burden shifts the math.
| Factor | Pressure-Treated Pine | Composite (Trex) |
|---|---|---|
| Upfront cost (350 sq ft) | $5,250–$8,750 | $10,500–$21,000 |
| Refinishing schedule | Every 2–3 years | None |
| Average annual maintenance | $250–$600 | $50–$100 (cleaning) |
| Lifespan | 15–25 years | 25–30+ years |
| Resale appeal | Standard | Strong |
Composites typically recoup their premium in a decade of skipped staining and sealing, and they hold up better in the resale appraisal. If you’re planning to sell soon, though, a well-built pine deck still returns most of its cost, and it’s why many sellers ask how much it should cost to replace a deck before listing.
How to Keep Your Deck Project on Budget
Pricing a deck accurately is half the job. These steps keep surprises off the final invoice.
- Get three itemized bids. Require every quote to break out materials, labor, permit, and disposal. Vague one-line bids hide markups.
- Price material fluctuations. Lumber and composite prices move with supply chains. Lock in material pricing in writing before work starts.
- Choose the right material for how long you’ll stay. Pine wins for a short horizon; composite wins beyond ten years.
- Simplify the design. Every extra level, stair run, and curve adds labor. A clean rectangular footprint costs less and wears trends better.
- Ask about off-season discounts. Many builders discount fall and winter jobs to keep crews busy.
- Verify licensing and insurance. A save of a few hundred dollars isn’t worth an uninsured crew or an unpermitted structure.
Frequently Asked Questions
How much does it cost to install a 12×12 deck?
A 12-by-12 deck (144 square feet) usually runs $2,500 to $5,500 in pressure-treated pine and $4,000 to $9,000 in composite, depending on height, railing, and local labor rates.
Is a deck or a patio cheaper?
A concrete or paver patio is generally cheaper, often $8 to $20 per square foot installed. A deck costs more but adds usable elevated space and tends to add more resale value on sloped lots.
Do I need a permit to build a deck?
Usually, yes, especially for a deck attached to the house or raised above a certain height (commonly 30 inches). Permits typically cost $150 to $500, and skipping one can complicate a future sale.
How long does a deck installation take?
A simple ground-level deck takes a crew about four to six days. A large composite or multi-level deck can take two to three weeks, plus a week or two for permitting and inspections.
Can I build a deck myself to save money?
You can save 50% or more on labor, but framing, footings, and flashing mistakes are expensive to fix and can be dangerous. Most homeowners are better off handling demolition or staining and leaving the structure to a licensed pro.
The Bottom Line
How much does a deck installation cost? In 2026, plan on $15 to $40 per square foot for most materials, with a typical 350-square-foot deck landing between $7,000 and $12,000 all-in. Wood keeps the entry price low; composite and PVC cost more now and far less over the life of the deck.
The best way to get a real number for your yard is to gather three itemized bids and compare them line by line, not just on the final figure. Once you’ve priced the boards and the labor, you can size the rest of the project with confidence and know exactly what your money is buying before the first board is cut.
