TimberTech composite decking typically costs $15-$30 per square foot installed, with a 300-square-foot deck often totaling $4,500-$9,000 before major structural repairs. Board collection, deck size, labor rates, railing, and demolition have the biggest effect on the final price.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed deck | $4,500 | $6,750 | $9,000 | 300 sq ft; boards and basic installation |
| Decking boards only | $1,500 | $2,700 | $3,900 | $5-$13 per sq ft |
| Installed price per sq ft | $15 | $22.50 | $30 | Excludes extensive framing repairs |
| Railing | $40 | $70 | $120 | Per linear foot, depending on system |
Assumptions: 300-square-foot, ground-level deck with standard access and sound framing; prices vary by region and collection.
What TimberTech Costs for a 300-Square-Foot Deck
For a straightforward 300-square-foot project, expect roughly $4,500-$9,000 for decking and basic installation. A midrange budget is about $6,750. This estimate assumes existing framing can be reused and excludes premium railing, stairs, permits, and disposal of an old deck.
TimberTech board pricing varies by product line, color, and retailer. As a planning range, composite boards commonly run $5-$13 per square foot before labor. Premium capped composite and PVC collections may cost more; check whether a quote covers only decking boards or includes trim, fasteners, and waste.
For a basic project, the installed square-foot range is more useful than a board-only price. Complex shapes and elevated decks can exceed it because they need extra framing, access work, and labor.
How boards, labor, and framing shape the quote
A contractor’s estimate may combine materials, installation, and site work. The breakdown below gives practical budgeting ranges for a 300-square-foot deck; the rows are not a fixed national rate card.
| Quote component | Low | Average | High | Pricing basis |
|---|---|---|---|---|
| TimberTech boards | $1,500 | $2,700 | $3,900 | $5-$13 per sq ft |
| Labor | $1,800 | $2,700 | $3,600 | $6-$12 per sq ft |
| Fasteners and trim | $250 | $500 | $900 | Hidden clips, fascia, edge details |
| Framing corrections | $0 | $600 | $1,800 | Limited repairs or added support |
| Removal and disposal | $300 | $750 | $1,500 | Existing deck and haul-away |
Material waste can add about 5%-10% to board orders, especially on diagonal layouts or decks with many corners. Labor is often estimated by area, but stairs, picture-frame borders, and detailed fascia work take additional time.
Ask the contractor to separate boards, labor, framing, and removal so competing quotes can be compared on the same scope.
Deck size, collection, and layout change the price
Deck area is a major cost driver: at $15-$30 installed per square foot, a 200-square-foot deck may cost $3,000-$6,000, while a 400-square-foot deck may run $6,000-$12,000. Small projects can have a higher per-square-foot rate because mobilization and setup costs are spread across less area.
Collection choice affects the material budget. Entry-level capped composite generally lands toward the lower end of the board range, while higher-end finishes, colors, and PVC options can push materials above $13 per square foot. Confirm the exact product name and whether the price includes matching fascia and stair boards.
Layout also matters. A simple rectangular deck needs fewer cuts than a curved or angled design. Stairs, multiple landings, and picture-frame borders add boards and installation hours. If the deck is more than about 30 inches above grade, local rules may require guardrails, adding material and labor.
For a 300-square-foot deck, upgrading the board selection or adding complex borders can move the quote by hundreds to several thousand dollars.
Labor hours and access can raise installation charges
A two-person crew may spend roughly 3-5 workdays installing decking on an uncomplicated 300-square-foot frame. Replacing boards on sound framing is usually faster than rebuilding the deck. Elevated structures, tight side-yard access, and extensive stair work can lengthen the schedule and raise the labor charge.
Regional labor rates are not uniform. Quotes in high-cost metro areas may run about 10%-25% above a comparable rural or lower-cost market; remote locations may also incur travel or delivery charges. Obtain local bids rather than treating national ranges as guaranteed prices.
Access and structural condition often matter more to labor than the deck’s area alone. Have the estimator inspect joists, ledger connections, and drainage before pricing a board-only replacement.
Removal, stairs, and railing add separate charges
Old decking removal and disposal commonly adds $300-$1,500 for a 300-square-foot project, depending on material, fasteners, and haul-away distance. New railing may add $40-$120 per linear foot. Stairs are often priced separately because stringers, treads, landings, and handrails need additional fitting.
Framing repairs can change the estimate substantially. Replacing a few damaged joists may add several hundred dollars, while widespread rot or an unsafe ledger connection can require a larger rebuild. A quote should identify any allowance for concealed damage instead of treating uncertain repairs as included.
Confirm whether the total covers demolition, disposal, stairs, railing, fascia, and tax before comparing bids.
Three TimberTech quote examples at different scopes
| Project | Scope | Estimated total | Approximate rate |
|---|---|---|---|
| Small replacement | 200 sq ft; basic boards; reusable framing | $3,600-$5,600 | $18-$28 per sq ft |
| Typical midrange | 300 sq ft; midrange boards; light trim work | $6,000-$8,400 | $20-$28 per sq ft |
| Detailed elevated deck | 400 sq ft; premium boards, stairs, railing, some repairs | $10,000-$16,000 | $25-$40 per sq ft |
These examples include installation but are budgeting estimates, not manufacturer-set prices. The detailed project exceeds the basic installed range because railing, stairs, and framing work add scope.
Match each estimate by square footage, collection, demolition, railing length, and repair allowance. A lower total may simply omit work that appears in another contractor’s bid.
Ways to lower the TimberTech decking bill
Keeping a structurally sound frame can avoid a costly rebuild, but it should be inspected for rot, proper spacing, and compatibility with the installation instructions. A simple rectangular layout, standard board lengths, and fewer decorative borders can reduce cuts and labor without changing the basic product.
Compare at least three itemized local quotes and ask whether the contractor can price a lower-cost TimberTech collection alongside the preferred one. Buying boards during a retailer’s seasonal promotion may help, but confirm quantities, delivery, color availability, and return terms before ordering.
Do not cut costs by skipping required railing, fasteners, flashing, or structural repairs. The most reliable savings come from controlling design complexity and avoiding unnecessary replacement work, not from leaving essential safety or installation items out.
