How to Estimate Fencing Jobs: Wood, Vinyl, and Chain Link
Fencing is a linear-foot business, which makes the math simple — and makes it dangerously easy to quote off a satellite photo. The difference between profit and loss on a fence job is what the ground does between the corners. Here's how to estimate fencing the right way.
Step 1: Measure the Run and Count the Posts
Walk the line and wheel-measure it — don't trust the plat map or the aerial. Then:
Posts = (run ÷ post spacing) + 1, plus one extra post per corner, end, and gate side
Standard spacing is 8 ft for wood and chain link, 6–8 ft for vinyl (follow the manufacturer).
Example — 150 ft of 6 ft cedar privacy with one gate:
- Line posts: 150 ÷ 8 + 1 = 20
- Gate adds a second hinge/latch post: +1
- Two corners: +2 → 23 posts
Step 2: Material Takeoff by Fence Type
Wood privacy (per 8 ft section): 1 post, 3 rails (2×4), ~16 pickets at 5.5" wide, one 60–80 lb concrete bag per post (two in soft soil), plus fasteners. Cedar pickets and pressure-treated posts are the standard combo.
Vinyl: sold as panel kits — count panels, posts, caps, and brackets. Order 5% extra; field-cutting vinyl panels wastes whole sections.
Chain link: fabric by the roll, line posts, terminal posts (heavier), top rail, tension bands, ties, and tension wire. Terminal posts and hardware are where new estimators under-order.
Typical installed price ranges (materials + labor):
| Fence Type | Per Linear Foot Installed |
|---|---|
| Chain link (4 ft) | $15–30 |
| Wood privacy (6 ft) | $35–70 |
| Vinyl privacy (6 ft) | $40–80 |
| Aluminum / ornamental | $50–100 |
Your market sets the number — but your cost sets your floor. Build it bottom-up and check it against the range.
Step 3: Price the Ground, Not Just the Line
Same fence, wildly different labor:
- Rock or caliche — auger refusal means digging bars, jackhammers, or core drilling. Add 50–100% to post-setting labor where you hit it.
- Slopes — stepped or racked panels take longer and waste material. Add 15–30% on graded runs.
- Tear-out — old fence removal and disposal: $3–8 per linear foot plus dump fees.
- Access — backyards with no gate access mean hand-carrying every post and bag of concrete.
- Utilities — call 811 before you dig. Hand-digging near marked lines is slow; price it.
Step 4: Gates Are Their Own Line Item
A gate is not 4 feet of fence. It's hinge hardware, a latch, a frame (or steel gate kit), heavier posts set deeper, and adjustment time. Price walk gates at $150–400+ and double drive gates at $400–1,200+ depending on material. Automated gates are a different trade — sub it or charge accordingly.
Step 5: Assemble the Bid
- Materials with 5–10% waste
- Labor: a 2-person crew sets 25–40 posts/day in normal soil, then hangs 150–250 lf of wood fence/day
- Concrete: bags × price (don't forget it — 23 posts is a pallet)
- Tear-out, haul-off, dump fees
- Gates, each
- Overhead and profit: 20–35% markup
Note your assumptions in the bid: "Price assumes normal soil conditions; rock encountered at post holes billed at $X/hole." That single sentence has saved more fence contractors than any tool in the truck.
Common Fencing Estimating Mistakes
Quoting from satellite photos. Aerials hide slopes, rock outcrops, old footings, and the neighbor's shed on the line.
Forgetting property lines. Make the homeowner confirm pins or order a survey — fence disputes are expensive to fix in concrete.
Pricing gates as fence footage. Every gate is hardware + labor + callbacks if it sags.
One soil assumption. Dig a test hole on the walkthrough if you have any doubt. Two minutes with a digging bar beats eating 23 jackhammered holes.
