How a Fence Is Installed, Step by Step

A fence install is a two-act job: set posts in concrete, then hang everything on them. Professionally, that's 1–3 days of on-site work spread around a 24-hour concrete cure, following the same six steps regardless of material. Here's what happens, in order — and where your money goes, since labor is roughly half of the installed price you see in our fence cost calculator.

The 30-second answer

Crews confirm the line and get utilities marked (811), stake and string the layout, auger post holes about 10 inches wide and 2 ft deep, set posts in concrete and let it cure, then attach rails and panels, hang the gates, and clean up for inspection. Post spacing is what changes with material — 8 ft for wood, 10 ft for chain-link, 6 ft for vinyl, aluminum, and composite — and the concrete cure in the middle is why even a small fence isn't a one-day job.

Step 1: Layout and utility marking

Before anything gets dug, two things must be true: the fence is on your property, and nothing buried is in its path.

• The line. The crew works from your survey stakes or plat — not from the old fence or the neighbor's hedge. If the boundary is uncertain, this is the moment to fix it; see fence permits and property lines for why building even a foot over costs thousands.
• 811. Someone files a locate request a few business days ahead, and utilities mark gas, electric, water, and cable with paint and flags. Free, and legally required in every state.
• Stakes and string. Corners and gate openings get staked, and a taut string line defines the exact path. Every post will be aligned to this string, so it's the accuracy step for the whole project.

Step 2: Dig the post holes

Post holes are augered along the string — powered auger on a normal yard, a tracked machine or hand digging where access is tight. Standards:

• Diameter: about 10 inches, leaving room for concrete around a 4-inch post.
• Depth: roughly one-third of the post height — 2 ft is standard for a 6-ft fence — or below the local frost line in cold climates, whichever is deeper.
• Spacing: 8 ft on center for wood, 10 ft for chain-link, 6 ft for vinyl, aluminum, and composite panels. On a 150-ft run that's roughly 16–26 line posts, plus corners and gate posts.

This is the step your soil taxes. Rocky ground slows augers badly (about +20% on the job), heavy clay adds ~8%, and a steep yard — where each hole is measured to step the fence downhill — adds up to 30%. When a quote is higher than the national ranges, it's usually this step the installer is pricing.

Step 3: Set the posts in concrete

Each post goes in its hole, concrete is poured around it (pre-mixed bags mixed on site for most residential jobs), and the post is plumbed with a level and aligned to the string before the mix stiffens. Gate and corner posts get the most concrete — they carry the load.

Then everything stops: the concrete needs to cure at least 24 hours (longer in cold weather) before panels load the posts. This pause is why a fence takes two site visits, and rushing it is how you get a leaning fence line a year later.

Step 4: Rails and panels

With the posts solid, the fence appears fast — usually the most satisfying day:

• Wood: horizontal rails (typically two or three) between posts, then pickets nailed or screwed one by one, or pre-built 8-ft panels hung whole. Board-on-board and shadowbox styles take longer than a basic stockade.
• Vinyl and composite: rails and panels lock or slide into routed posts — fast, but unforgiving of post-spacing errors, which is why spacing is exactly 6 ft.
• Chain-link: top rail is fitted, then mesh fabric is unrolled, stretched tight with a come-along, and tied to the rails and posts.

On slopes, panels are either stepped (each panel level, dropping in increments) or racked (panels parallel to the grade) — a design choice worth settling before the quote, since it affects labor and looks.

Step 5: Hang the gates

Gates get their own step because they're the only moving part and the first thing to fail on a cheap install. Hinges and latches mount to the beefed-up gate posts, the gate is hung and adjusted for smooth swing and a reliable latch. Pool-enclosure gates must be self-closing and self-latching by code in most states. Cost-wise, gates are per-opening line items — about $350 for a walk gate, $800 for a double, $1,500 for a driveway gate at mid-range.

Step 6: Cleanup and inspection

The crew hauls spoil dirt and packaging, grades around the posts, and walks the line checking plumb, level, and latch operation. If your permit requires a final inspection, it gets scheduled now — the inspector typically checks height, setbacks, and (for pool barriers) gate hardware. Keep the passed-inspection record; it matters when you sell.

DIY or hire it out?

Labor is roughly half the installed price — on a mid-range 6-ft wood fence at $33/lf, that's ~$16/lf you could theoretically keep, about $2,400 on a 150-ft yard. The honest trade: an auger rental, a weekend of digging, roughly a ton of concrete in 80-lb bags, and the skill of keeping a long run straight. Chain-link and basic wood are genuinely DIY-able; routed vinyl and composite systems punish imprecise post spacing and are better left to pros. Material choice math is in wood vs. vinyl.
