Concrete form boards price ranges from about $2 to $8 per linear foot for common lumber, while a contractor may charge $6 to $18 per linear foot to set and remove basic forms. Total cost depends on pour dimensions, board size and condition, labor, access, and whether stakes, bracing, or removal are included.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| New form lumber | $2 per linear ft | $4 per linear ft | $8 per linear ft | Common 2-by boards; grade and length affect price |
| Basic installed forms | $6 per linear ft | $11 per linear ft | $18 per linear ft | Setting and stripping; ordinary access |
| Small slab formwork | $250 | $650 | $1,500 | Typical small residential pour perimeter |
| Reusable form rental | $1.50 per linear ft | $3.50 per linear ft | $7 per linear ft | Rental period, deposit, and delivery may be extra |
What concrete form boards cost by linear foot
For a straightforward slab edge, buyers commonly budget $2-$8 per linear foot for new boards and about $6-$18 per linear foot for installed formwork. A small 10-by-12-foot slab has 44 linear feet of perimeter, putting basic installed forms near $264-$792 before unusual site work or delivery. Contractors may set a minimum charge even when the perimeter is short.
Budget around $11 per linear foot for an ordinary installed form, then adjust for lumber grade, board height, and site conditions. The estimate assumes common lumber, a simple rectangular layout, standard residential labor, and no major excavation or engineering. Assumptions: Midwest labor rates, standard materials, normal access, and a basic slab edge.
How lumber, stakes, and labor appear in a formwork quote
A quote may separate the boards from the work needed to brace, align, and strip them. Ask whether listed lumber is purchased or rented, and whether the contractor credits reusable boards after the pour. The following ranges describe typical basic work, not specialized foundation forming.
| Cost item | Typical price | What changes the charge |
|---|---|---|
| 2-by form boards | $2-$8 per linear ft | Width, grade, length, and new versus reused |
| Stakes and bracing | $0.50-$2.50 per linear ft | Stake spacing, soil, and concrete pressure |
| Labor to set and strip | $3-$9 per linear ft | Layout, corners, access, and crew productivity |
| Equipment and delivery | $50-$300 per job | Distance, loading, and equipment needs |
| Removal and disposal | $1-$4 per linear ft | Reuse, cleanup, and debris volume |
Labor and lumber together usually make up most of a basic forming bill. Form-setting labor often runs $45-$85 per hour per worker; a two-person crew working 4-8 hours may therefore account for $360-$1,360 before lumber and other charges.
Board height, slab thickness, and corners change the estimate
Most flatwork uses 2-by-4 or 2-by-6 lumber, but the right form height depends on the planned concrete depth and finished grade. A 4-inch slab edge usually needs less bracing than a 6- or 8-inch edge. Taller forms, steps, curves, and frequent corners take longer to align and may need stronger stakes or additional blocking.
Expect higher rates when a form is over 6 inches tall or the layout has more than four corners. Slopes and uneven ground can add roughly $1-$5 per linear foot for leveling and extra bracing. Long runs also matter: a perimeter above 150 linear feet may require more material handling, though a larger project can sometimes lower the per-foot labor rate.
How crew hours affect installed form board prices
A small rectangular patio may take a two-person crew 4-8 hours to measure, cut, stake, and level forms. A driveway or foundation perimeter can require 1-3 workdays, especially if the site needs grading or has multiple elevations. At $45-$85 per worker-hour, the crew rate can change the total substantially even when lumber prices are similar.
Confirm that the labor allowance includes both setup and stripping after the concrete cures. Some bids price only installation and charge separately to remove forms, clean reusable boards, or haul away damaged lumber. Concrete curing time is not usually billed as continuous labor, but scheduling a return visit may affect the contractor’s minimum charge.
Regional lumber and labor rates shift the total
Urban markets with high wages and delivery costs can run 10%-25% above a typical national estimate. Rural areas may have lower labor rates but higher delivery fees if lumber yards or contractors are far away. Areas with active construction demand can also see higher charges during busy seasons.
Compare local installed rates, not lumber prices alone. A low board price may be offset by a delivery fee, minimum labor charge, or limited reuse. Request pricing by linear foot and a separate total for delivery, stripping, and disposal so quotes can be compared on the same scope.
Three sample budgets for concrete form boards
These examples use ordinary residential conditions and show why perimeter and scope matter. Actual quotes vary with local labor, lumber availability, and access.
- Small patio: A 10-by-12-foot slab has 44 linear feet of edge. At $3 per foot for boards, $1 per foot for stakes, and 6 crew-hours at $60 per hour, the estimate is about $484 before delivery or disposal.
- Two-car driveway: A 20-by-20-foot area has 80 linear feet of perimeter. At $4 per foot for boards, $1.50 per foot for bracing, and 12 crew-hours at $65 per hour, the estimate is about $1,100 before site leveling.
- Long shed pad: A 12-by-30-foot slab has 84 linear feet of perimeter. At $5 per foot for boards, $1.50 per foot for stakes, and 10 crew-hours at $70 per hour, the estimate is about $1,265 before delivery.
Assumptions: New standard lumber, simple layouts, ordinary access, and labor rates within the stated examples.
Where buying, renting, or reusing boards saves money
For a one-time small pour, compare the cost of buying boards with a rental quote that includes delivery, pickup, and deposit terms. Reusing straight, undamaged lumber can lower material expense, but warped boards may create uneven edges or require extra labor. Used boards are less suitable where the finish depends on a clean, consistent slab edge.
Control the scope before choosing the cheapest lumber. Provide accurate dimensions, mark steps and curves, and clear the form line before the crew arrives. Ask whether the quote includes stakes, stripping, and disposal, and get at least three bids with matching specifications. Avoid paying for upgraded form systems unless the slab height, concrete pressure, or layout requires them.
