You need a ranch, split-rail, or agricultural fence and you want it built by someone who's actually set posts on the eastern plains, not a crew that only does 6-foot privacy panels in tract-home backyards. I'm Julian Lopez. I own J.A's Privacy and Perimeter, I'm licensed and insured in Colorado, and I've spent 15+ years and 500+ projects building fence across the Denver metro, from Wash Park clay to the open parcels east of I-25. Rail fencing is a different animal than privacy fencing, and the crew that quotes you is the crew on the job.

Most ranch-fence pages in Denver give you a stock photo of a white three-rail and a phone number. That's not useful when your real question is whether two-rail or three-rail is right for your line, how deep the posts go in Thornton's newer subdivisions versus the sandy loam out toward eastern Aurora, whether the county lets you top a run with barbed wire, and whether Colorado's shared-fence statute means your neighbor owes half. I'll answer all of it on this page, because on an agricultural parcel the wrong call costs you a whole run of fence when the first open-range wind comes down off the plains.

I build two-rail and three-rail ranch fence in #1 Grade Western Red Cedar and pressure-treated pine, split-rail in cedar, and ranch-three-rail in aluminum-reinforced vinyl when you want the look without the re-stain schedule. I set every post to frost depth, 36 inches minimum and 42 in heavy clay, with a gravel-and-concrete footing. Barb-wire toppers go on commercial and agricultural jobs where the county allows it.

Ranch Fencing: What It Is and When It's the Right Call

Ranch fencing is open-rail fence, two or three horizontal rails between posts, with no solid infill. It marks a boundary, contains livestock or horses, and lets wind, sightlines, and snow pass straight through instead of treating the fence like a sail. That last part is why it's the right material out on the eastern plains where a solid privacy panel would get flattened by the first hard chinook.

Where ranch fence wins. Acreage and agricultural parcels east of I-25, horse properties, the borders of large lots in Thornton's Todd Creek and North Creek master plans where the covenant wants an open rural look, front-boundary runs on rural residential lots, and any line where you want definition without blocking the view of the Front Range.

<aside class="my-6 rounded-md border border-border bg-card p-4 text-sm">Open-plains fact: Wind on the parcels east of I-25 regularly runs 60+ mph with nothing to break it. A three-rail open fence sheds that load through the gaps. A 6-foot solid fence in the same spot needs steel posts and full concrete just to survive the winter, which is why ranch rail is the honest call on exposed acreage.</aside>

Not for you if this is the situation

Don't put in a ranch fence if what you actually need is privacy or a dog that stays in the yard. Open rail contains horses and cattle; it does not contain a determined dog and it screens nothing. If a neighbor's window looks into your yard, or you're keeping a small breed in, rail is the wrong material and I'll tell you that on the site walk instead of selling you a fence you'll rip out in two years. Look at privacy fence installation or chain link for dog containment instead. A ranch fence is for a boundary and for large livestock, nothing more, and I'd rather lose the rail job than sell you the wrong one.

Two-Rail vs Three-Rail Ranch Fence: How to Choose

Short answer: three-rail contains horses and large livestock and reads more finished; two-rail marks a boundary and costs less per foot. The rail count is a containment and budget decision, and the post spacing and footing depth don't change between them. Here's how I think it through at the site walk.

Three-rail ranch fence

Three horizontal rails, typically at roughly 16, 32, and 48 inches, on posts spaced 8 feet on center. The tighter rail spacing is what actually holds a horse, a horse leans and pushes, and a two-rail gap is wide enough for a leg to go through. Three-rail is the standard for any property with animals, and it's the look most Todd Creek and North Creek covenants have in mind when they call for "ranch-style" or "open-rail" fence. It's also what most people picture when they say white ranch fence.

Two-rail ranch fence

Two rails, usually at 24 and 44 inches. Less material per foot, faster to build, and the right call when the fence is marking a boundary rather than containing animals. Good on a rural residential front line, a driveway border, or a garden and pasture divider where nothing's leaning on it. If you add livestock later, a third rail can be retrofitted onto the same posts.

<blockquote class="my-6 border-l-4 border-primary pl-4 italic text-foreground/85">"The rail count follows the animal, not the budget. If you're keeping horses, it's three-rail, full stop, a two-rail line is a vet bill waiting to happen. If you're marking a boundary, two-rail saves you real money per foot and does the job."</blockquote>

For a rail fence that never needs staining, ranch-three-rail is available in aluminum-reinforced vinyl, covered on the vinyl and PVC fencing page. Want a line-item quote that breaks out rail count, post spacing, and footing depth? Get a free on-site estimate and I'll itemize it.

Split Rail Fence Installation: Cost Variables and What You're Paying For

Split-rail is the rustic cousin of ranch fence: split cedar rails set into mortised or routed posts, two or three rails high, with a hand-hewn look instead of milled uniformity. It's a favorite on rural residential lots and acreage borders where the goal is a natural, Colorado-ranch character. I don't publish a per-foot price because the number is driven by variables that only a real site walk pins down, and any quote that skips these is a guess.

Rail count. Two-rail split-rail uses less cedar per foot than three-rail. Same perimeter, different material total. Don't compare a two-rail bid to a three-rail bid and assume someone's overcharging.
Cedar grade. #1 Grade Western Red Cedar with tight knots and no pith costs more than #2 and lasts longer under our UV. On split-rail the grade shows, because you see the raw wood.
Post count and spacing. Split-rail posts sit 8 to 10 feet on center depending on rail length. Corners, ends, and gate posts carry more load and get upsized.
Footing depth and soil. Denver's frost line is 36 inches. Heavy bentonite clay lots get 42-inch footings with a deeper gravel base. More concrete and excavation per post than a market that doesn't freeze.
Terrain and grade change. A level parcel installs faster than a lot that steps down toward a drainage. Split-rail steps cleanly on a slope, but each step is custom.
Gates and access. Walk-gates, a 12-foot double-drive farm gate for equipment, or a wider run for a truck. Each has its own hardware and heavier gate posts.
Barb-wire or mesh add-ons. A welded-wire or field-fence backing to hold in smaller animals, or a barbed strand on top where the county allows it. Both add material and steps.
Demo and haul-away. Pulling an old failed rail line and disposing of it is real labor and gets line-itemed, not buried.

Two split-rail runs of identical footage can land at meaningfully different numbers based on the list above, which is why a square-foot ballpark over the phone routinely misses by a wide margin.

3-Rail Wood Fence: The Post and Footing Spec That Actually Holds

A 3-rail wood fence lives or dies on the posts, not the rails. The rails are the easy part. The reason rail fences lean, sag, and drop rails after a few winters is almost always a shortcut in the footing, and out on exposed acreage that shortcut shows up fast because there's nothing breaking the wind.

Posts and material

I build 3-rail in #1 Grade Western Red Cedar and in pressure-treated #2 Southern Yellow Pine when budget calls for it. Cedar's natural oils resist ground-line rot and it holds up better under our elevation UV; pine is the budget option and needs a shorter maintenance cycle. Line posts sit 8 feet on center for a horse-containment three-rail. Corner, end, and gate posts step up in size because they carry the pull of the whole run.

Footings, because this is where fences fail

36-inch minimum depth to Denver's frost line. On windy plains lots and any run carrying gate load, I go 42 inches. A rail post shallower than frost depth heaves the first spring, and once it heaves the rails pull out of the next post.
Gravel-and-concrete footing, not dry-pack. A gravel base breaks the water column at the bottom of the hole so meltwater doesn't freeze against the post and jack it upward. Bentonite clay along the western metro holds water against a post like a sponge, which is exactly why the gravel matters here more than in a dry-soil market.
Domed concrete crown above grade. Concrete brought above finished grade and shaped to shed water away from the post. Flat crowns pool water at the base and rot the ground line.
Hot-dip galvanized or stainless hardware. Every bracket and fastener. Cheap electroplated screws bleed rust down the rail face by year three.

<blockquote class="my-6 border-l-4 border-primary pl-4 italic text-foreground/85">"On the open parcels east of I-25 the wind never stops, so I set rail posts the same way I set gate posts, deeper footing, deeper gravel, domed crown. A rail fence that survives one calm summer can still get pulled apart by the first sustained plains wind if the posts were set shallow."</blockquote>

If a contractor quotes you a 3-rail wood fence and doesn't ask about your soil or name a footing depth, you're paying for a fence that won't clear a Front Range winter. Get a free on-site estimate and I'll name the post grade, spacing, and footing depth in writing.

Agricultural Fencing Across the Denver Metro and Eastern Plains

Ranch and agricultural fence installation looks different city to city because the soil, the wind exposure, and the covenant rules all shift as you move east. Here's where I work and what changes from one line to the next. This is the part that matters for agricultural fence installation in Thornton, CO and the plains parcels around Westminster, where the demand is real but almost nobody has a dedicated crew for open-rail work.

Ranch and agricultural fence in Thornton. Thornton's newer subdivisions and the Todd Creek and North Creek master plans run strict Architectural Review Committee specs, and Todd Creek's ACC review window is 15 business days. Many of those covenants actually call for an open rural rail look, so three-rail cedar or ranch-vinyl usually clears the committee cleanly. I submit the ARC packet before scheduling so the run passes the first time.
Agricultural fencing in Westminster. The plains parcels and larger lots on the north and east edges catch open wind with little to break it, so I set rail posts to full frost-depth footings and orient the run to shed the prevailing load. HOA open-space borders in Promenade and Hyland Village want coordinated height and material, which I match to what's already approved next door.
Ranch fence in Aurora. Aurora's geology is split, bentonite clay on the west around Tollgate, stable sand-gravel and sandy loam on the east around Saddle Rock and Painted Prairie. That means I set footing depth by address: 42 inches in the western clay, closer to 30 in the stable eastern substrate. The newer master plans east of E-470 also run heavy HOA review.
Rail fencing in Denver. Expansive clay in Capitol Hill and Wash Park means every rail post goes 36 inches to frost line, no exceptions. Denver's front-yard rule caps fences over 4 feet at less than 50 percent solid, and an open two- or three-rail fence passes that rule easily where a solid panel wouldn't.
Ranch and split-rail in Lakewood. The defining variable is grade. Lots near Green Mountain and Bear Creek run 4 to 8 feet of change, so I step the rail line cleanly down the slope rather than letting rails float out of level.
Rail fencing in Arvada. A mix of historic Olde Town lots and newer master plans like Candelas and Leyden Rock, so the right build changes block to block. I verify the local rule for your specific address before quoting.

I've set posts in Wash Park clay and stretched fence across Green Valley Ranch gravel. Wherever your line runs, the crew that quotes you is the crew on the job. Call <a href="tel:7206096094">720-609-6094 or book a free on-site estimate.

Frequently Asked Questions

How deep should ranch fence posts go in Colorado clay?

Denver's frost line is 36 inches below finished grade, so that's the minimum depth on every rail post I set. On heavy bentonite clay lots along the western metro, and on any post carrying gate load or full plains-wind exposure, I go 42 inches. The footing is a gravel base topped with concrete and a domed crown above grade, not dry-pack. Clay holds water against the post, so the gravel breaks the water column and keeps meltwater from freezing against the post and heaving it. A rail post set shallower than frost depth heaves the first spring, and once it heaves the rails pull out of the next post.

Do you install barbed wire fence on agricultural or commercial properties?

Yes, on commercial and agricultural jobs where the county allows it. A barbed strand or two on top of a rail or field-fence line is common on working acreage for livestock control. It's regulated at the county and municipal level, so what's permitted on an agricultural parcel east of I-25 may not be allowed on a residential lot inside a city limit or in an HOA. I verify the rule for your specific address and zoning before quoting, and I don't top a residential fence with barbed wire where code or covenant prohibits it. On commercial perimeter work, barbed wire and razor ribbon toppers are installed to ASTM F567.

What's the difference between two-rail and three-rail ranch fence?

Three-rail has tighter rail spacing (roughly 16, 32, and 48 inches) and is the standard for containing horses and large livestock, because a two-rail gap is wide enough for a leg to go through. Two-rail (usually 24 and 44 inches) uses less material per foot and is the right call when you're marking a boundary rather than containing animals. Post spacing and footing depth don't change between them, so the choice is a containment and budget decision. A third rail can be retrofitted onto the same posts later if you add livestock.

How much does split rail fence installation cost?

I don't publish a per-foot rate because the number is driven by real variables: rail count (two vs. three), cedar grade (#1 vs. #2), post count and spacing, footing depth (36 inches standard, 42 in heavy clay), terrain and grade change, gate count and size, any welded-wire or barbed-wire add-ons, and demo of an old line. Two runs of identical footage can land at meaningfully different numbers based on that list, which is why a phone ballpark routinely misses by a wide margin. Call 720-609-6094 for a free on-site measurement and I'll write you an itemized, line-by-line quote.

Does Colorado's shared fence statute apply to my ranch fence?

It can, and it's worth knowing before you build. Colorado's fence law (the state's fence and partition-fence statutes, including the rangeland provisions that govern who is responsible for livestock fencing) treats agricultural and rangeland fences differently than an ordinary residential yard fence. On a shared agricultural boundary, cost-sharing and maintenance responsibility between adjoining owners can be governed by statute rather than left to a handshake, and whether the fence is a legal partition fence affects who owes what. This is a legal question tied to your parcel's zoning and use, so I build to the correct spec for an agricultural boundary and recommend you confirm the cost-sharing details with the county or an attorney before assuming your neighbor owes half. I'll build it right; the statute question is one to verify for your specific line.

Can a 3-rail wood fence hold up to the wind on the eastern plains?

Yes, and that's actually where open rail fence belongs. The gaps between rails let 60-plus mph plains wind pass straight through instead of loading the fence like a sail, which is why a three-rail line survives on exposed acreage east of I-25 where a solid 6-foot privacy panel would need steel posts and full concrete just to make it through winter. The catch is the posts: on open plains lots I set rail posts to 42-inch footings with a deeper gravel base and a domed crown, the same way I set gate posts. A rail fence fails on the plains when the posts were set shallow, not because the rails caught wind.

What wood do you use for ranch and split-rail fencing?

#1 Grade Western Red Cedar with tight knots and no pith is the standard. Cedar's natural oils resist ground-line rot and it holds up better under our elevation UV, and on split-rail the grade shows because you see the raw wood. Pressure-treated #2 Southern Yellow Pine is the budget option; it costs less but warps more and needs a shorter maintenance cycle under our UV load. If you want a rail fence with no re-stain schedule at all, ranch-three-rail is available in aluminum-reinforced vinyl. I'll walk you through the trade-offs at the estimate so you're choosing on real information, not a sales pitch.

Do you install ranch and agricultural fencing in Thornton and Westminster?

Yes. Ranch, split-rail, and agricultural fencing across Thornton and Westminster is a core part of this work, along with Denver, Aurora, Lakewood, and Arvada. In Thornton, master-planned communities like Todd Creek and North Creek run strict ACC specs and often call for an open rural rail look, so three-rail cedar or ranch-vinyl usually clears the 15-business-day review cleanly. On the plains parcels around Westminster, the open wind exposure drives full frost-depth footings and careful run orientation. I submit the HOA Architectural Review packet before scheduling so the run passes the first time. Call 720-609-6094 for a free on-site estimate.
