Half round posts typically cost $8-$35 each for common fence sizes, while installed prices often reach $25-$75 per post depending on length, wood treatment, soil, and labor. Half round posts price estimates also change with order quantity, delivery distance, post spacing, and whether old fencing must be removed.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Post only | $8 | $18 | $35 | Common 6-8 ft treated post |
| Post per linear foot | $1.25 | $2.50 | $4.50 | Depends on wood, diameter, and length |
| Installed post | $25 | $45 | $75 | Setting only, ordinary soil and access |
| 100-ft fence materials | $250 | $550 | $1,000 | Posts only; spacing and post size vary |
| 100-ft fence installed | $1,000 | $2,200 | $4,000 | Posts and basic rails, no major grading |
Assumptions: U.S. retail pricing, typical treated softwood, standard access, and no unusual delivery or ground conditions.
What half round fence posts cost by size
Most buyers pay about $8-$35 per half round post, with a typical 6- or 7-foot post landing near $12-$22. Smaller 4-5-foot pieces for garden edging or light paddock use can cost $5-$14, while 8-10-foot posts commonly run $20-$45. Hardwood, large diameters, and specialty treatment can push prices above that range.
For rough budgeting, expect $1.25-$4.50 per linear foot. A 6-foot post at $15 works out to $2.50 per linear foot, but length alone does not determine the quote: a thicker post uses more timber and may be graded for heavier fencing. Half round posts have one flat face and one curved face, so quoted dimensions can describe the rounded diameter rather than a square post width.
A practical starting budget is $15-$25 per post for a durable, treated 6-8-foot fence post before delivery and installation. Prices assume a common softwood product sold individually or in a modest bundle, rather than reclaimed timber or a custom-cut order.
A fence line uses fewer posts when spacing is wider, but spacing must suit the fence design and expected load. At 6-8-foot centers, a straight 100-foot run typically requires roughly 14-18 line posts, plus stronger end and corner posts. Gates and changes in direction add posts, and many projects need heavier pieces at those points.
How timber, labor, and delivery shape the quote
A post-only price is just one part of a fence estimate. Retailers may quote the timber separately from treatment, freight, cutting, and the work of digging and setting each post. Contractors may instead give a linear-foot installation price that includes posts, rails, fasteners, and labor, so the estimate should be checked for what is actually included.
| Quote item | Typical price | What changes it | Common billing unit |
|---|---|---|---|
| Half round posts | $8-$35 each | Length, diameter, species, treatment | Each or per linear foot |
| Rails and fasteners | $3-$12 per fence foot | Rail count, lumber grade, hardware | Per linear foot |
| Installation labor | $15-$45 per post | Soil, access, layout, crew productivity | Per post or $50-$100 per hour |
| Equipment and hole digging | $3-$12 per post | Auger access, rock, hole depth | Per post or job fee |
| Delivery and disposal | $50-$250 per order | Distance, load size, old fence removal | Flat charge or trip fee |
| Concrete or gravel | $3-$15 per post | Setting method and local material price | Per hole |
A crew spending 12-20 hours at $60-$90 per hour would add approximately $720-$1,800 in labor, before equipment or materials.
Labor and site preparation can equal or exceed the price of the posts themselves. Ask whether the quote includes digging, post setting, leveling, rails, hardware, cleanup, and disposal. A low quote that covers only post placement is not directly comparable with a complete fence installation.
Length, diameter, and treatment change post prices
Length and thickness are major price drivers because longer, heavier pieces require more timber and cost more to handle and ship. A 4-5-foot post may be adequate for a low garden boundary, while a 7-8-foot post is more common where a fence needs meaningful height and embedment. Posts longer than 8 feet often cost $20-$45 each, with large or premium pieces reaching $50 or more.
Diameter affects strength and appearance. A light 3-4-inch post may suit a decorative boundary, but a 5-6-inch post is often selected for a sturdier fence or heavier rails. Larger posts can add $5-$20 each compared with a small equivalent, and they may require wider holes, more gravel or concrete, and extra handling time.
Treatment and species also matter. Pressure-treated pine generally costs less than cedar or durable hardwood, while untreated timber may have a lower checkout price but is more vulnerable to decay where it contacts soil. Cedar or other naturally durable choices may cost 20%-60% more than standard treated softwood. Verify that the product is rated for its intended ground-contact use; a surface treatment is not necessarily equivalent to pressure treatment.
Ground conditions shift the installed price as much as the product specification. Loose, workable soil allows fast digging; roots, buried rubble, clay, or rock can add $10-$40 or more per post in labor and equipment. A 24-inch-deep hole is easier and cheaper than a deeper hole, though required depth depends on post height, local conditions, and fence design.
Compare posts with the same length, diameter, species, and ground-contact rating. A per-post comparison is misleading if one quote includes a 4-inch untreated piece and another includes a thicker pressure-treated post intended for burial.
How long does half round post installation take?
For a straightforward 100-foot fence, a two-person crew may need 1-2 days to lay out the line, dig approximately 14-18 post holes, set posts, and install basic rails. That schedule assumes open access and ordinary soil. A smaller repair involving three or four posts may take 2-5 hours, although travel and minimum charges can make a short service call relatively expensive.
Contractors may charge $50-$100 per hour for general fence labor, or quote $15-$45 to set each post. Per-post rates are easier to compare when the number and depth of holes are clear. Hourly billing can be reasonable where conditions are uncertain, but the estimate should state the expected crew size and hours or explain how extra digging time will be priced.
Post setting may use tamped soil, gravel, or concrete. Gravel can drain well and is quick to use in some soils; concrete adds material and handling costs and can make future removal harder. The right method depends on the fence and ground, so a contractor should specify the setting method rather than leaving it as an unexplained line item.
Allow extra time and money when access prevents an auger from reaching the fence line. Hand-digging, hauling posts through a narrow gate, or working near utilities can slow installation and add labor. Before digging, underground utility locations should be checked through the appropriate local service.
Three half round fence quotes for real project sizes
A small garden boundary is a relatively inexpensive use of half round posts. For 40 feet with 4-foot posts spaced about 6 feet apart, a buyer might need eight posts at $8-$14 each, or $64-$112 for posts. Basic rails and fasteners could add $120-$300, with $250-$600 in labor and digging. A realistic total is approximately $450-$1,000, excluding a gate.
A typical 100-foot yard fence might use 16 posts, 6-7 feet long, priced at $12-$24 each. Posts would total $192-$384; rails and hardware may cost $300-$800, and installation labor and digging could add $700-$1,600. With $75-$200 for delivery or equipment, the overall estimate is about $1,300-$3,000, assuming no removal, major grading, or premium lumber.
A more substantial 200-foot paddock line using 8-foot posts of roughly 5-6 inches in diameter could require 27-30 line posts, plus reinforced corner and gate posts. At $22-$40 per standard post, the line posts alone may cost $594-$1,200. Rails, hardware, corner bracing, and labor can bring the project to roughly $4,000-$9,000. Rocky ground or heavy-duty specifications may exceed that range.
These examples are budgeting scenarios, not fixed national quotes. They assume posts around 6-8 feet apart; closer spacing raises the count, and gate openings or corners change the layout. Confirm whether the contractor’s linear-foot price includes every post and rail, since some quotes exclude end assemblies and gates.
Regional price differences for delivered timber and labor
Material prices vary with local timber supply, retailer competition, and freight. In areas near sawmills or timber-growing regions, standard posts can fall 5%-15% below a broad U.S. retail estimate. In dense coastal cities or remote communities, delivery and handling can put comparable materials 10%-25% higher. These are useful planning adjustments, not guarantees; a local supplier’s written quote is more reliable.
Labor rates often produce a larger regional difference than the posts. A rural crew may charge 10%-20% less than a contractor in a high-cost metro market, while urban access restrictions, parking, and disposal fees can add 10%-30% to the installed total. Long distances from the supplier can also make a small order expensive because delivery is charged per trip rather than per post.
Climate and local ground conditions affect specifications too. Wet areas and frequent soil contact increase the importance of proper ground-contact treatment; frozen ground may limit winter scheduling, while dry, hard soil can slow excavation. The quote should identify the post treatment and setting depth rather than relying on a generic description such as “treated timber.”
Use a regional adjustment on labor and freight, not on every line item equally. For example, a $500 materials order may stay close to the supplier’s price while installation in a high-cost market adds several hundred dollars compared with a rural job.
Removal, gates, and difficult soil add extra charges
Removing an old fence can add $3-$10 per linear foot for basic dismantling and hauling, or more when posts are set in concrete. Contractors may charge $10-$30 to extract an individual old post, with disposal and concrete breakup billed separately. Ask whether the estimate includes recycling or landfill fees and whether the old material must be cleared before new holes are dug.
A gate requires more than two ordinary line posts. Heavier gate posts, hinges, latch hardware, and bracing can add $100-$500 or more per opening, depending on gate width and materials. Corner posts and terminal posts may also need greater diameter or deeper setting, so a quote based only on the total number of identical posts can understate the project.
Delivery minimums commonly add $50-$250, especially for a small order or a supplier far from the job. Rush delivery, difficult unloading, or a second trip can add another $25-$150. If the supplier charges a flat freight fee, consolidating posts, rails, and hardware into one delivery may reduce the total.
Get separate prices for fence removal, gate hardware, difficult holes, and delivery. Separate line items make it easier to spot a high charge and to compare bids that include different levels of preparation. If digging reveals rock or buried concrete, agree on the extra-work rate before the crew proceeds.
How to lower the half round post project price
Start by setting the fence length, height, post spacing, and gate locations before requesting bids. A clear layout helps prevent overordering and makes contractor estimates comparable. Avoid reducing spacing or post size simply to cut the initial quote; undersized posts can flex or fail, turning a small saving into an early repair expense.
Compare at least three local quotes using the same post length, diameter, treatment, rails, and setting method. Request both a material-only price and a complete installed price where practical. Check whether tax, delivery, old-fence removal, disposal, gate hardware, and cleanup are included. A bid that is $300 lower but excludes removal or rails may not be the less expensive option.
Buying a full bundle can lower the per-post price, but only if the order matches the final layout and the buyer has a dry, secure place to store unused timber. Ask the supplier about quantity discounts and delivery minimums. Standard lengths and common treated softwood are usually less costly than custom cutting, premium species, or unusual dimensions.
Site preparation can reduce paid crew time. Clear brush, mark the fence route, and confirm access for the delivery vehicle and digging equipment, while leaving utility marking and excavation safety to the proper process. Schedule during a contractor’s less busy period when available, but do not delay urgent repairs if a damaged fence creates a safety or livestock-containment problem.
The most dependable savings come from a precise scope and a fair comparison, not from choosing the cheapest untreated post. Keep essential post strength and ground-contact protection, and remove optional upgrades only after confirming they are not required for the fence’s load, local conditions, or intended lifespan.
