A 1x4x8 pressure treated board typically costs $4-$10, with an average near $6.50 at U.S. home improvement stores. Price varies with treatment level, grade, local lumber supply, and whether the board is sold individually or in a bundle.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| One 1x4x8 treated board | $4 | $6.50 | $10 | Common treated pine, before tax |
| Price per linear foot | $0.50 | $0.81 | $1.25 | Board price divided by 8 feet |
| Ten-board purchase | $40 | $65 | $100 | Before delivery and tax |
What an 8-foot pressure treated 1×4 usually costs
For a standard ground-contact or above-ground treated pine board, buyers commonly pay about $4-$10 each. A typical shelf price is around $6-$7, or roughly $0.75-$0.88 per linear foot. Select or straighter boards and specialty treatment can cost more; local promotions or bulk purchases may bring the unit price down.
Assumptions: U.S. retail pricing, one board, common treated pine, standard access, and no delivery charge. The “1×4” is a nominal size: actual dimensions are usually about 3/4 inch thick by 3 1/2 inches wide. It is generally used for light outdoor trim, fencing details, garden projects, and other non-structural work.
Budget about $6.50 per board before tax for a typical retail purchase. The treatment rating should match the intended exposure, and the lumber label should be checked rather than relying on the board’s appearance.
How treatment, labor, and delivery shape a lumber quote
A material-only purchase is often the full cost for a small DIY project. For installed work, labor and setup can exceed the lumber bill, especially when the job requires cutting, fastening, removal, or difficult access. A contractor may also include hardware and a minimum service charge.
| Quote component | Typical price | What changes it |
|---|---|---|
| Treated 1x4x8 board | $4-$10 each | Grade, treatment, retailer, and region |
| Exterior-rated screws | $8-$20 per small pack | Coating, length, and quantity |
| Carpenter labor | $50-$100 per hour | Local rates and job complexity |
| Delivery | $25-$100 per order | Distance, order minimum, and retailer |
| Cutting or removal | $10-$40 per board or task | Shop service or site labor and disposal |
A simple installation may take 10-20 minutes per board, but measuring, layout, and setup add time. Ask whether a quote includes fasteners, delivery, cutting, and cleanup before comparing totals.
Which board dimensions and treatment ratings change the price?
Length and width affect the total bill: an 8-foot 1×4 is usually less expensive than longer or wider stock, while a 10- or 12-foot board may carry a higher unit price and be harder to find. Compare price per linear foot when lengths differ. A bowed or heavily checked board can also reduce usable material, so inspecting each piece matters for visible trim.
Treatment category is another key distinction. Above-ground lumber is intended for installations with adequate airflow and no soil contact. Ground-contact rated lumber is designed for more severe exposure and may cost roughly 10%-30% more, depending on retailer and market. The treatment label and use instructions take precedence over a general price estimate.
Pay for the required exposure rating, not an upgrade that the project does not need. For structural or load-bearing use, confirm the grade and building requirements; a 1×4 is not a substitute for appropriately sized framing lumber.
Ways to lower the cost of a small treated-lumber project
Measure the project and make a cut list before buying. An 8-foot board can yield multiple shorter pieces, but saw kerf and end trimming reduce the usable length. Buying only the needed quantity avoids leftovers, while purchasing a bundle can reduce the per-board price if the boards will be used soon and can be stored flat and dry.
Compare the same treatment category and grade across stores, and calculate the delivered price rather than comparing shelf tags alone. Pick straight boards in person when possible; a low-cost warped board can create extra cutting waste or replacement expense. For a one-board repair, pickup is often cheaper than paying a delivery minimum.
Keep the spec consistent when comparing quotes, then remove avoidable delivery, waste, and labor charges. Use fasteners rated for treated lumber, since incompatible hardware can corrode and lead to repairs.
How regional lumber prices differ across U.S. markets
Retail prices vary with freight, local inventory, and competition. As a rough planning allowance, a small-market or remote-area price may run 5%-20% above a well-stocked metro store, while areas with strong supplier competition may be 5%-10% below a national retail midpoint. These are comparison ranges, not guaranteed regional price lists.
Seasonal outdoor-project demand can also tighten inventory in spring and early summer. A particular grade or treatment rating may be temporarily unavailable, making a substitute more expensive. Call ahead for the exact board specification and confirm whether the quoted price is per piece, per bundle, or for a contractor-supplied order.
Use local store quotes as the deciding evidence because lumber costs are regional and inventory-sensitive. Delivery distance can outweigh a small difference in the sticker price.
Three project totals using 1x4x8 treated boards
A short garden edging or trim repair using two boards at $5 each costs about $10 for lumber. Add $8-$15 for a share of exterior-rated fasteners, and the DIY material total is roughly $18-$25 before tax, assuming pickup and no special cuts.
A 10-board outdoor detail project at $6.50 per board costs about $65 for lumber. With $15-$25 in hardware and $25-$50 delivery, the materials-and-delivery total is approximately $105-$140 before tax. This assumes straightforward access and minimal cutting.
A contractor installing 20 boards may charge $100-$200 for lumber, $20-$40 for fasteners, and about 3-5 labor hours at $50-$100 per hour. The estimated total is $270-$740 before tax or disposal, depending on layout and local labor. For installed work, labor scope—not the board price—is often the largest source of quote variation.
When a different board or repair makes more sense
For a dry interior location, untreated pine may cost less, often around $3-$7 for an 8-foot 1×4, but it is not an equivalent choice for exposed outdoor use. Cedar or other naturally durable species may cost roughly $8-$18 or more per board, depending on grade and market. The higher material cost may be worthwhile for appearance or specific project requirements, but it should be compared on the same dimensions.
If only one short section is damaged, replacing that piece can cost less than rebuilding an entire assembly. However, a repair may not solve rot or movement caused by water exposure, poor drainage, or failed supports. Check surrounding material before pricing a small patch, and use treatment appropriate to any freshly cut ends as directed on the product label.
Choose the least expensive material that meets the project’s exposure and strength requirements, not simply the lowest shelf price.
