Homeowners and contractors typically pay for 6x6x12 pressure treated posts in the low to mid-range for basic yard or fencing projects. Main cost drivers include wood species, treatment level, grade, quantity, and delivery. The following figures reflect typical U.S. pricing in USD and assume ground contact, standard grade, and common retail distribution channels.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| 6x6x12 Pressure Treated Post | $18 | $32 | $60 | Ground-contact PT pine or fir; common #2 grade |
| Delivery (Pro/Drop-Off) | $20 | $35 | $60 | Varies by distance |
| Installation / Labor (optional) | $0 | $12 | $40 | Per post if installed by a pro |
| Warranty / Overhead | $0 | $5 | $15 | Includes basic warranty |
| Taxes & Permits (where applicable) | $0 | $6 | $15 | Depends on jurisdiction |
Overview Of Costs
Cost ranges for a single 6x6x12 pressure treated post typically fall between $18 and $60, depending on grade and treatment, with delivery and installation adding to the total. For projects with multiple posts, per-post price generally decreases due to bulk shipping and supplier pricing. Assumptions: region, specs, labor hours.
Cost Breakdown
The following table illustrates common cost components and how they contribute to the overall price. The numbers assume a standard 12-foot post and ground-contact treatment.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials | $18 | $32 | $60 | Wood, treatment, and typically #2 grade |
| Labor | $0 | $12 | $40 | Assumes optional installation by a pro |
| Delivery/Disposal | $20 | $35 | $60 | Delivery to site; disposal of waste may apply |
| Permits / Taxes | $0 | $6 | $15 | Jurisdiction dependent |
| Overhead / Warranty | $0 | $5 | $15 | Basic warranty on post integrity |
What Drives Price
Treatment level and wood species are primary price levers; longer post life or rot resistance adds cost. Length and diameter directly impact material weight and price. A 12-foot, 6×6 post is at the upper end for residential fence or deck framing. Heavier grades or specialty species can push prices higher. Additionally, bulk purchases and supplier proximity to the project reduce per-post transport costs.
Ways To Save
Strategies to reduce the cost of 6x6x12 posts include buying in bulk, selecting common yard-stock sizes, and coordinating pickup rather than delivery. Assess site access to avoid extra handling fees. If installation is not required, purchasing only posts and performing labor in-house can cut costs.
Regional Price Differences
Prices vary by market: urban, suburban, and rural regions show different ranges due to labor costs and shipping. Urban areas often have higher delivery fees and taxes but greater availability; Suburban markets typically offer a balance of price and convenience; Rural regions may incur higher freight but lower material premiums. Expect +/- 10–25% deltas across these regions for similar post specifications.
Labor & Installation Time
When labor is included, a pro may charge by the post or by project, with typical rates around $15–$40 per post for simple installs. For a crew performing multiple posts, time per post decreases due to efficiency. Installation time and crew size influence total costs and may add to delivery scheduling complexities.
Real-World Pricing Examples
Three scenario cards illustrate typical quotes for common project scales. Assumptions: region, specs, labor hours.
Basic Post Purchase
Specs: 6x6x12 PT post, standard grade; no delivery. Labor: none. Total: $18–$32 per post. Per-post price reflects materials only.
Mid-Range Project
Specs: 8 posts, mix of basic and higher-grade PT; delivery included; minimal installation. Total: $320–$420. Includes delivery and modest overhead.
Premium Setup
Specs: 12 posts, ground-contact rated, expedited delivery, basic installation and warranty. Total: $600–$900. Higher-grade materials and service add-ons drive the cost.
Maintenance & Ownership Costs
Over a typical 10–15 year horizon, PT posts may require re-treatment or replacement due to ground contact wear or damage. A lifetime cost of ownership for a small fencing section can run $1,000–$1,800 when maintenance, replacement posts, and occasional reinforcements are included. Expect periodic inspections and occasional reapplication of protective coatings, if applicable.
