Quick answer: To build a wood fence, first call 811 to mark underground utilities and confirm your property lines and any permit rules. Set 4x4 posts in concrete, spaced a little under 8 feet apart, buried about a third of the post's length and below your frost line. Let the concrete cure, attach horizontal rails (commonly at three heights), then fasten the pickets. It is a doable but physically demanding weekend-plus project. For long runs, sloped ground, or hard digging, post the job free on Qiggz and let a local pro quote it.
A fence looks simple from the curb: posts, rails, boards. The reason a straight, plumb, long-lasting fence is harder than it looks is everything that happens before the first picket goes on. Posts that are too shallow heave in winter. Posts spaced wrong waste lumber. A line that ignores the property boundary turns into a dispute with a neighbor. Get the layout and the posts right, and the rest is repetition.
This is a buildable DIY project for a homeowner who is comfortable with tools and does not mind the digging. It is also one of the most physical jobs on the home-improvement list, so be honest about the labor before you commit a weekend (or two) to it.
Here is the full sequence: the prep that protects you, the tools and materials, the numbered build, a realistic read on difficulty, and when handing it to a pro is the smarter call.
Before you dig: the steps that protect you
Do not skip this part. It is the difference between a clean project and an expensive mistake.
- Call 811 first. In the United States, calling 811 (the "call before you dig" service) gets your underground utilities located and marked for free. Hitting a gas, power, or water line is dangerous and costly, and digging without calling can be illegal in many places.
- Find your property pins and lines. Build inside your boundary. Locate your property pins or have the line confirmed so the fence does not cross onto a neighbor's land, which is a common and avoidable source of conflict.
- Check permits and rules. Many cities and counties require a permit for a fence and limit its height, especially in front yards. Homeowners associations often have their own rules. Confirm both before you buy materials, because requirements vary by location.
- Talk to your neighbor. A quick conversation about a shared boundary fence saves a lot of grief later.
Why 811 is non-negotiable: the service is free, and it protects you from striking buried utilities. Make the call (or the online request) several business days before you plan to dig, and wait for the marks.
Is building a fence a good DIY project?
It can be, with a clear-eyed view of the work involved.
- Difficulty: intermediate. The skills are basic, but accuracy matters. Posts must be plumb and in a straight line, and rails must be level.
- Effort: high. Digging post holes by hand is hard work. Renting a power auger helps a lot, but the project is still labor-heavy.
- Time: a fence is rarely a single-day job. Setting posts in concrete adds a built-in wait, since the concrete needs time to cure before you load the posts with rails and pickets.
- Where it gets hard: sloped or rocky ground, very long runs, hard or clay-heavy soil, and gates (a gate that sags or sticks is the most common fence complaint).
If any of those describe your yard, read the "when to hire a pro" section before you buy a single board.
Tools and materials you will need
Exact materials depend on your fence style and length. A standard wood privacy or picket fence uses posts, horizontal rails, and pickets.
Materials - 4x4 posts (pressure-treated is common for ground contact; cedar is a popular rot-resistant pick for the visible parts) - 2x4 lumber for the horizontal rails - Fence pickets or boards - Concrete mix for setting the posts - Gravel for the bottom of each post hole (helps drainage) - Exterior-rated galvanized or coated screws or nails - Gate hardware (hinges and a latch) if you are adding a gate
Tools - A post-hole digger, and ideally a rented power auger - A shovel and a digging bar for roots and rock - A tape measure, string line, and stakes for the layout - A level (and ideally a post level) - A speed square and a pencil - A drill or impact driver, or a nail gun - A circular saw or handsaw - A wheelbarrow for mixing concrete - Work gloves and eye protection
How to build a wood fence, step by step
Step 1: Lay out the fence line
After you have called 811 and confirmed your lines and permit, mark the corners and ends of the fence with stakes. Run a taut string line between them to define a straight, level reference for the whole fence. This string is what keeps your posts in a clean line.
Step 2: Mark and space the posts
Mark each post location along the string. A common spacing is a little under 8 feet on center, which lets standard 8-foot lumber span between posts for the rails with room to attach. One contractor guide cites 7 feet 8 inches as a working number, adjusted for slope and obstructions. Set your corner, end, and gate posts first, then the line posts between them.
Step 3: Dig the post holes
Dig each hole deep enough to set the post about a third of its total length into the ground, and deep enough that the base sits at least 6 inches below your local frost line so winter freezing does not heave the post. A power auger makes this dramatically easier than a hand digger.
Step 4: Set the posts in concrete
Add a few inches of gravel at the bottom of the hole for drainage, then stand the post so its outside face just touches the string line. Pour in concrete (a common rule of thumb is about one 60-pound bag per hole, depending on hole size), and plumb the post in both directions with a level. Brace it so it cannot shift.
Step 5: Let the concrete cure
Let the concrete set before you hang anything on the posts. Setting posts is the step most worth patience, because rushing it is how you end up with a leaning fence. Follow the concrete product's cure guidance.
Step 6: Mark and attach the rails
Mark the rail positions on each post so the rails line up across the run. A common three-rail layout marks heights at 6 inches, 30 inches, and 54 inches above the ground. Cut the rails to span between posts and fasten them with exterior-rated screws or nails, keeping each rail level.
Step 7: Trim the posts to height
Once the rails are on and the line is set, cut the tops of the posts to a consistent height (or your chosen decorative profile) so the fence reads as one clean line.
Step 8: Fasten the pickets
Attach the pickets or boards to the rails with a nail gun or screws. Use a spacer block for consistent gaps (for a picket fence) or butt the boards tight (for a privacy fence), and check vertical with a level every few boards so the fence does not drift.
Step 9: Build and hang the gate
Build the gate square and brace it diagonally so it does not sag, then hang it on sturdy hinges and add the latch. A well-braced gate is the single biggest factor in whether a fence still works smoothly in a few years.
Step 10: Finish and protect
Depending on your wood, seal, stain, or paint the fence to protect it from moisture and sun. Pressure-treated lumber often needs to dry out before it takes a finish, so check the product guidance.
When to hire a pro
Plenty of fences get built by homeowners, but some yards and styles tip the math toward hiring out. Consider a pro if:
- Your ground is sloped, rocky, or heavy clay that makes hand-digging brutal.
- The run is long, and the days of digging and hauling add up fast.
- You want a level, professional line on uneven terrain, which takes experience.
- The fence material is heavy (some metal, masonry, or composite systems) or the design is complex.
- You are not confident about property lines, permits, or hitting utilities.
A landscaper or carpenter who builds fences regularly owns the augers and tools, reads slope quickly, and sets posts that stay plumb. For many homeowners, the labor saved is worth the cost.

The bottom line
Building a fence is mostly about doing the unglamorous parts right. Call 811, confirm your property line and permit, space and set your posts correctly (about a third of the post buried, below the frost line, plumb in concrete), and let that concrete cure before you load it. Rails and pickets are the fast, satisfying finish once the bones are right.
If your yard fights back with slope, rock, or a long run, that is your cue to bring in help rather than lose two weekends to it. Post your fence project free on Qiggz and let local pros quote it, with no lead fees and no commissions. Find a local pro or hire a landscaper.
Frequently asked questions
How far apart should fence posts be?
A common spacing is a little under 8 feet on center, which lets a standard 8-foot rail span between posts. One contractor guide uses 7 feet 8 inches as a working figure, adjusted for slope and obstacles. Corner, end, and gate posts get set first, with the line posts spaced evenly between them.
How deep should fence posts go?
A common guideline is to bury about a third of the post's total length, and to make sure the base sits at least 6 inches below your local frost line so freezing soil does not heave the post in winter. Deeper, well-set posts are what keep a fence standing straight for years.
Do I need a permit to build a fence?
Often yes. Many cities and counties require a permit and limit fence height, especially in front yards, and homeowners associations may add their own rules. Requirements vary by location, so confirm with your local building department before you buy materials.
Do I really need to call 811 before digging?
Yes. In the United States, calling 811 gets your underground utilities located and marked for free, which protects you from striking a gas, power, or water line. Digging without it is dangerous and can be illegal in many areas. Make the call several business days before you dig.
How long does it take to build a fence?
A wood fence is rarely a one-day job. Beyond the digging and assembly, setting posts in concrete adds a required curing wait before you can attach rails and pickets. Plan on a multi-day project, longer for difficult soil, long runs, or sloped ground.
Is it cheaper to build a fence yourself?
Doing it yourself mainly saves on labor, since you still buy posts, rails, pickets, concrete, and hardware. The trade-off is significant physical effort and the risk of a leaning or crooked fence if the posts are not set well. For tough yards, a pro's result can be worth the cost.
