Decking materials typically cost $2-$18 per square foot, while a professionally installed deck often totals $20-$65 per square foot before major site work. Board type, deck size, labor, railing, and removal of an old deck drive the final quote; this decking material cost comparison separates material prices from installed costs.

|---|---|---|---|---|
| Pressure-treated pine boards | $2/sq ft | $3.50/sq ft | $6/sq ft | Boards only; grade and region affect price |
| Cedar or redwood boards | $4/sq ft | $7/sq ft | $12/sq ft | Species and board grade vary |
| Composite boards | $5/sq ft | $9/sq ft | $15/sq ft | Midrange capped boards cost more |
| PVC boards | $8/sq ft | $13/sq ft | $18/sq ft | Premium synthetic decking |
| Installed deck project | $20/sq ft | $38/sq ft | $65/sq ft | Basic platform through complex builds |
What decking materials cost for a 300-square-foot deck
For boards alone, a 300-square-foot surface generally costs $600-$5,400, depending on material. A typical project using pressure-treated pine boards may spend $1,050 on decking, while composite boards at $9 per square foot come to about $2,700. These figures exclude framing, labor, railing, stairs, and demolition.
A straightforward new deck with standard pressure-treated framing and basic access often costs $6,000-$11,400 installed at $20-$38 per square foot. Composite or PVC installations with upgraded framing, hidden fasteners, or detailed edges can reach $12,000-$19,500. Board-only prices are not comparable to full installation quotes.
Assumptions: 300-square-foot ground-level rectangle, standard residential board widths, ordinary access, and midrange U.S. labor rates. Material prices reflect broad retail and contractor ranges, not a guaranteed local quote. Lumber markets, freight, sales, and seasonal inventory can move a bid beyond these estimates.
How boards, labor, framing, and fasteners shape the quote
A deck quote includes more than the visible boards. Framing lumber, joists, posts, connectors, fasteners, stairs, and railings can equal or exceed the decking material expense. Labor commonly accounts for 35%-60% of an installed project, especially when the site is raised, sloped, or difficult to reach.
| Quote component | Typical price | Unit or scope | What changes it | Budget note |
|---|---|---|---|---|
| Decking boards | $2-$18 | Per sq ft | Species, grade, cap, profile | Usually excludes waste |
| Framing lumber | $4-$10 | Per sq ft | Height, joist spacing, spans | May need structural upgrades |
| Installation labor | $8-$25 | Per sq ft | Board type, layout, access | Intricate patterns cost more |
| Fasteners and connectors | $1-$4 | Per sq ft | Hidden clips, corrosion rating | Composite clips can add expense |
| Delivery and disposal | $150-$1,500 | Per project | Distance, old deck volume | Confirm haul-away in writing |
Contractors may quote labor by square foot or by crew hours. As a rough check, a two-person crew working 24-40 hours at a combined billed rate of $100-$180 per hour implies $2,400-$7,200 in labor, though actual production depends on stairs, cuts, and framing condition. Ask the estimator to separate decking, structure, fasteners, and labor.
Which deck size, board grade, and joist spacing shift pricing?
Deck size affects both total spending and unit price. A compact 120-square-foot landing may cost $3,000-$7,800 installed because stairs, mobilization, and railing do not shrink in proportion to area. A simple 400-square-foot platform may run $8,000-$20,000, with a lower per-square-foot rate when its shape is uncomplicated.
Board grade and profile also matter. Common pressure-treated boards cost less than clear, appearance-grade cedar; premium cedar can add $3-$6 per square foot over basic pine. Composite with a protective cap often costs $2-$5 per square foot more than an uncapped entry-level product. Wider boards and specialty colors can carry additional product premiums.
Joist spacing must match the manufacturer’s requirements. Standard wood decking is often installed over joists 16 inches on center, while some composite products require 12-inch spacing, particularly when laid diagonally. Tightening spacing from 16 to 12 inches can add roughly 15%-25% to framing material and labor. Check the board warranty and installation specification before comparing prices.
Elevated decks cost more than ground-level platforms because posts, bracing, stairs, and guardrails increase. A deck 6 feet above grade may add $15-$35 per square foot compared with a similar low platform, depending on engineering and access. Irregular angles, curved borders, picture-frame edges, and diagonal layouts raise cutting time and waste.
Which choices cut decking costs without sacrificing durability?
Keeping the footprint rectangular and using standard board lengths reduces cuts, waste, and labor. A simple layout can save 5%-15% compared with a design involving several corners or diagonal rows. Where practical, align the deck size with readily available board lengths to limit offcuts and avoid special orders.
Compare material quotes on the same basis: board thickness, cap construction, warranty, color, and required joist spacing. Entry-level composite may be a false bargain if it needs closer framing or costly clips not included in the estimate. Pressure-treated pine can lower the initial bill, but the homeowner should include periodic cleaning, sealing, and board replacement in the comparison.
Retaining sound framing can save money when replacing only the deck surface, but a contractor should inspect joists, ledger attachment, posts, and flashing. Reusing compromised framing can create safety and warranty problems. Cut scope through simple geometry and verified reuse, not by skipping structural repairs.
Request at least three itemized bids using the same square footage and material specification. Check whether each price includes tax, delivery, disposal, permit fees, railing, stairs, and cleanup. Scheduling during a contractor’s slower period may improve availability, but weather and local demand make discounts unpredictable; compare the complete written totals rather than a claimed percentage off.
Where regional labor and delivery change deck material prices
Material prices are not uniform nationwide. In high-cost coastal metros and areas with elevated freight charges, delivered decking and labor can run 10%-25% above a broad national estimate. Rural locations may have lower hourly labor but higher delivery or travel charges, particularly for specialty composite or PVC boards.
In the Midwest and South, pressure-treated pine is widely available and often sits near the lower end of its range. Cedar and redwood are more accessible in parts of the West and Northwest, where local supply can reduce freight. In regions where those species are shipped long distances, prices may approach $10-$15 per square foot for higher grades.
Labor rates and building requirements can outweigh material differences. A contractor in a large metropolitan area may charge $75-$125 per worker-hour, while smaller markets may fall nearer $45-$85. Permit rules, snow loads, coastal corrosion exposure, and wildfire-resistant construction requirements can also change framing and connector specifications. Local quotes should identify delivery, tax, and code-related upgrades separately.
Three 300-square-foot deck quotes with different board materials
These examples show how similar project sizes can produce different totals. Each assumes a new, uncomplicated platform with basic stairs and railing, standard pressure-treated framing, and no unusual grading or utility relocation. Local labor and code requirements can move the final amount.
| Example | Material and scope | Boards | Other work | Estimated total |
|---|---|---|---|---|
| Budget pine | Pressure-treated, 300 sq ft | $900-$1,500 | Labor, frame, fasteners, basic rail $5,400-$8,000 | $6,300-$9,500 |
| Midrange composite | Capped composite, 300 sq ft | $2,400-$3,600 | Labor, frame, clips, rail $7,000-$10,500 | $9,400-$14,100 |
| Premium PVC | PVC boards, 300 sq ft | $3,600-$5,400 | Labor, upgraded frame, rail $8,000-$12,000 | $11,600-$17,400 |
For the pine example, a two-person crew might spend 30-45 hours on demolition-free construction, billed at an effective combined rate of $100-$160 per hour. Composite installation may take 35-50 hours because of clip systems, layout, and finish detailing. These crew-hour estimates are illustrative, not a promise of job duration.
Removing an existing deck, rebuilding stairs, or adding a high guardrail can raise any example by thousands of dollars. A quote that appears much lower may exclude framing, permits, or disposal. Compare identical scope and material specifications before treating one total as the best price.
How wood and composite compare over ten years of upkeep
Pressure-treated wood is usually the lowest-cost purchase, but it needs routine care. Cleaning and resealing may cost $1-$3 per square foot per service when hired out, generally every two to three years depending on exposure and finish. Over ten years, three treatments on 300 square feet can add roughly $900-$2,700, excluding repairs or owner-supplied labor.
Cedar and redwood avoid some chemical-treated appearance but still require periodic cleaning and protective finish if color retention matters. Unfinished wood weathers naturally; restoring its original appearance later can require sanding and more labor. Local sun, rain, snow, and shade affect both maintenance schedules and service life.
Composite and PVC typically need washing but not staining. Professional cleaning may cost $150-$450 per visit for a modest deck, while routine owner cleaning usually costs less. Their higher initial board price can be partly offset by less finishing work, but damaged boards, fading, heat retention, and warranty terms should be considered. Compare ten-year upkeep using the finish schedule actually intended for the deck.
No material has a guaranteed lifespan in every setting. Proper drainage, ventilation, fastening, and framing protection matter as much as the board choice. Composite warranties often cover defined product defects but may exclude installation errors, structural framing, or unusual wear; read the coverage conditions rather than treating warranty length as a service-life promise.
What stairs, railing, and old-deck removal add to the budget
Basic railing often adds $40-$100 per linear foot installed for standard wood, while metal or composite rail systems may cost $60-$160 per linear foot. A 30-foot perimeter can therefore add about $1,200-$4,800. Cable, glass, custom metal, and code-required guardrail designs are generally at the top end or above it.
Stairs commonly cost $300-$1,200 per flight for simple wood construction; multiple landings, wide stairs, or composite treads can push the charge to $1,500-$4,000. Confirm whether handrails, footings, and excavation are included. On a raised deck, stairs and railing can rival the cost of the surface boards.
Deck demolition and disposal often range from $5-$15 per square foot, or $1,500-$4,500 for a 300-square-foot structure. Cost rises with multiple levels, difficult access, heavy framing, or disposal restrictions. Delivery may add $75-$300 for standard local lumber orders, with longer distances or crane placement costing substantially more.
Permits and inspections vary by city and project height. A straightforward permit may cost $100-$500, while engineered plans or complex reviews can add $500-$2,000 or more. Verify permit responsibility and debris hauling before accepting a fixed-price bid.
