Millboard decking price per m2 typically works out to about $140-$240 for boards and $250-$450 for a professionally installed deck in the United States. The final quote depends on imported-product availability, deck size, substructure, site access, and whether old decking must be removed.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Millboard boards | $140/m2 | $185/m2 | $240/m2 | Approx. $13-$22 per sq ft; modeled landed-material budget |
| Installed decking | $250/m2 | $335/m2 | $450/m2 | Approx. $23-$42 per sq ft; typical uncomplicated project |
| 20 m2 installed deck | $5,000 | $6,700 | $9,000 | Before unusual structural work or extensive removal |
Assumptions: U.S. estimates are budget ranges, not a published nationwide Millboard price list; imported supply, freight, local labor, and project scope can change quotes substantially.
What a 20 m2 Millboard deck usually costs
For a straightforward 20 m2 deck, plan on roughly $5,000-$9,000 installed, with about $6,700 as a practical midpoint. This estimate covers Millboard boards, ordinary fasteners and trims, a sound existing or new substructure, and standard installation. It does not assume major grading, new stairs, railing, structural repairs, or complicated geometry.
At the midpoint, the installed rate is about $335/m2, or $31 per sq ft. Board material alone is modeled at $140-$240/m2. Those figures reflect a premium imported composite product and a U.S. landed-cost allowance; the exact amount must be confirmed with a dealer or importer serving the project location.
For comparison, a 10 m2 balcony-sized platform might cost $2,500-$4,500 installed, while a 40 m2 deck could run $10,000-$18,000 before add-ons. Larger projects may reduce labor cost per m2 when the layout is simple, but total material and freight charges rise with area.
Millboard is a molded, resin-mineral composite board with a wood-grain surface, rather than conventional timber. Product lines, board profiles, colors, clips, and finishing accessories can differ in availability and price. A quote should identify the exact product and accessories rather than listing only “composite decking.”
How boards, framing, and labor shape the quote
The boards are only one part of the installed price; framing, installation, and import logistics can add a comparable amount. The table gives typical planning allowances per square meter for a standard project. These are broad U.S. estimates and should not be added mechanically when a contractor provides a single bundled rate.
| Cost component | Typical range | What it may include | Pricing basis |
|---|---|---|---|
| Millboard boards | $140-$240/m2 | Deck boards and landed product cost | Product, profile, freight, availability |
| Labor | $55-$110/m2 | Layout, cutting, fastening, finishing | About $45-$90 per crew-hour equivalent |
| Substructure materials | $25-$70/m2 | Joists, supports, connectors, blocking | Depends on framing condition and spacing |
| Equipment and delivery | $10-$35/m2 | Local delivery, handling, tool use | Distance, order size, access |
| Removal and disposal | $15-$55/m2 | Taking up existing boards and haul-away | Not included in a new-build estimate |
| Permits and overhead | $5-$25/m2 | Permit allowance, insurance, contractor overhead | Local rules and quote structure |
Labor estimates vary with crew size and layout. A basic 20 m2 installation may require roughly 20-35 crew-hours, while complex edges, picture framing, steps, or concealed fastener details can increase the time. is a useful way to check whether an itemized labor allowance matches the quoted crew rate and expected hours.
Why board profile, deck height, and framing change the price
Deck area alone does not predict the quote: profile choice, joist condition, and elevated construction can shift the total by thousands of dollars. The following thresholds help explain why two decks with the same floor area may receive very different estimates.
-
Board profile and finish: Premium or less commonly stocked profiles can cost 10%-25% more than a standard available selection. A special order may also involve a higher minimum purchase or longer freight route.
-
Joist spacing: If existing joists are more than 16 inches on center, a contractor may need to add framing or rebuild the substructure to meet product requirements. Reinforcing a 20 m2 deck can add about $400-$1,400, depending on access and lumber prices.
-
Height and supports: A ground-level platform on sound framing is generally less costly than a deck raised 3 feet or more. Taller structures may need additional posts, bracing, stairs, and railing, adding $1,000-$5,000 or more to a small-to-medium project.
-
Shape and perimeter detail: A rectangular deck with few cuts installs faster than one with curves, angled corners, or multiple borders. Detailed picture framing can add roughly $20-$60 per linear foot for labor and extra trim, depending on the design.
-
Order size and freight: Small orders can have higher delivery charges per m2 than a full pallet. If the product is not stocked locally, import handling and shipping can add 10%-30% to the materials allowance.
Local building code requirements also matter. A deck attached to a home, raised above grade, or fitted with stairs may require permits, guardrails, inspections, or structural upgrades. Contractors should separate required work from optional upgrades in the estimate.
What U.S. labor and installation time add
Installation labor commonly accounts for about $55-$110/m2 on a simple Millboard project, before costly framing repairs or detailed trim work. Regional contractor rates, job minimums, and the availability of installers familiar with the product can move the figure outside that range.
A small 10 m2 job may not cost half as much as a 20 m2 project. Mobilization, material handling, and scheduling create minimum charges, so a compact deck can carry a higher per-m2 labor rate. For a standard 20-30 m2 surface, a crew of two or three might need two to four working days, including layout and finishing; demolition and framing can extend the schedule.
In higher-cost metropolitan markets, labor can run 15%-30% above a broad national planning allowance. Rural areas may have lower hourly rates but higher travel or delivery charges, particularly when the contractor must source specialty boards from a distant supplier.
Ask whether the quote covers substructure inspection, board cutting, fascia, edge details, cleanup, and final waste removal. A low labor price that excludes those tasks can appear cheaper but leave substantial costs outside the contract.
How quotes differ between coastal cities and smaller markets
Location changes both the installation rate and the landed price of an imported board. In large coastal metros, the combined installed estimate may be 15%-30% above the ranges shown here because labor, insurance, access restrictions, and delivery costs tend to be higher.
In lower-cost inland or suburban markets, a straightforward installation can land around 5%-15% below the midpoint if a contractor can obtain the boards efficiently and reuse a suitable frame. That discount is not guaranteed: limited local supply can erase labor savings through freight, special-order handling, or longer scheduling delays.
Remote locations may face a different cost pattern. A contractor could charge a travel fee or delivery surcharge of $150-$600 or more, especially for a small order. Ask whether the supplier quote is ex-works, delivered to the driveway, or includes carrying materials to the deck; those terms affect the true installed budget.
Because Millboard availability varies, a local estimate should name the supplier, delivery location, board model, and currency basis. U.S. prices converted from overseas retail listings may omit import costs, domestic taxes, distribution margin, and warranty-service considerations.
Removal, stairs, and borders that can raise the total
Extras can add $500-$4,000 or more to a modest deck, so they should appear as separate line items. Removing and disposing of old decking often costs $15-$55/m2. Rotted joists, damaged ledger boards, or unstable footings are not ordinary deck-board replacement and may require a separate repair allowance.
Stairs are priced by design and width, not only by floor area. A basic short stair run may add $500-$1,500, while wider stairs with landings, guards, or difficult access can exceed $2,500. Railings can add roughly $80-$200 per linear foot, depending on material, height, and code requirements.
Fascia, edge boards, and border details may add $20-$60 per linear foot when material and labor are combined. Hidden clips or specialty fasteners should be listed in the material schedule. If a contractor includes a contingency for concealed damage, the estimate should state its percentage and how unused funds are handled.
Delivery and minimum order charges deserve attention on small decks. Request both the board quantity and the assumed waste allowance; a straightforward layout may need about 5%-10% extra, while diagonal patterns or complex borders can require more.
Three sample Millboard deck quotes by project size
These examples show how scope—not just square footage—sets the budget. They use the modeled U.S. ranges above and assume no major permit complications or structural rebuild beyond the stated scope.
| Project | Scope and labor | Material rate | Estimated total |
|---|---|---|---|
| 10 m2 ground-level platform | Two-person crew, about 18-25 crew-hours; existing frame checked and reused | $175/m2 boards; $45/m2 framing allowance | $2,800-$4,000 |
| 20 m2 standard deck | Two- or three-person crew, about 25-40 crew-hours; new basic framing | $185/m2 boards; $45/m2 framing allowance | $5,500-$8,000 |
| 30 m2 raised deck | Three-person crew, about 45-65 crew-hours; stairs, railing, and added supports | $205/m2 boards; $65/m2 framing allowance | $11,000-$17,000 |
The first example has a higher per-m2 total than a larger simple platform because delivery and crew setup are spread over less area. The raised-deck example includes components that are not part of a basic deck-surface price, so it should not be compared directly with a board-only quote.
Millboard compared with wood and other composite boards
Millboard’s higher upfront price can be compared with lower-cost wood and stocked composite options, but the products are not identical. Pressure-treated wood decking may cost about $25-$60/m2 for boards, while common composite boards often run roughly $50-$130/m2 before installation. Millboard’s modeled $140-$240/m2 board allowance reflects its premium product positioning and U.S. import uncertainty.
A low-priced wood surface can require periodic staining or sealing, while composite products generally avoid that specific upkeep. Actual maintenance depends on exposure, cleaning instructions, and the manufacturer’s care requirements. Compare the warranty terms, installation details, and replacement-board availability rather than relying on a broad “maintenance-free” claim.
For an existing deck with sound joists, replacing only the surface may avoid a full frame replacement, but the selected product must be compatible with the framing and support spacing. If the joists are deteriorated or incorrectly spaced, installing new boards over them can create performance and warranty problems. Obtain a written inspection and compare surface-only work with a complete rebuild.
Ways to trim a Millboard quote without cutting corners
The most reliable savings come from simplifying the layout, confirming the frame before ordering, and avoiding unneeded structural or decorative work. A rectangular design with standard board lengths reduces cuts and waste. Keeping stairs, borders, and railing to the required scope can prevent extras from overtaking the surface budget.
-
Have the contractor inspect joist spacing and condition before material is ordered. Reusing a compliant frame can avoid a $25-$70/m2 substructure allowance, but only when it is sound and compatible with product requirements.
-
Choose a readily available profile and color rather than a special-order option. Ask the supplier whether a larger combined order can reduce delivery cost per m2.
-
Compare at least three itemized quotes using the same product, board quantity, waste allowance, framing scope, and delivery terms. A quote that omits disposal or edge finishing is not directly comparable with a complete installation price.
-
Schedule removal and installation together when practical, and clear access to the work area before the crew arrives. This can reduce handling time and avoid separate mobilization charges.
-
Keep a written allowance for concealed damage instead of approving an unspecified open-ended contingency. Require a photo and price approval before extra repairs begin.
Do not reduce costs by ignoring required joist spacing, drainage, fastening instructions, or local guardrail rules. A technically compliant installation protects the product warranty and can prevent premature repairs that outweigh the initial savings.
