Professional fence installation typically costs $20–$50 per linear foot when you hire a contractor, but tackling it yourself can cut that in half. If you've got a weekend, basic tools, and patience for measuring twice, a DIY fence build is absolutely doable—and you'll actually know the job was done right. This guide walks you through the real steps, costs, and pitfalls so you can decide if DIY fencing makes sense for your property.
Assess Your Site and Get Permits
Before you buy a single post, walk your property line with a tape measure and stake markers every 6 feet. Mark any slopes, rocks, tree roots, or drainage issues—these affect post placement and material choices more than anything else.
Check your local building codes and HOA rules. Most municipalities require fence permits ($50–$300), setback distances from property lines (typically 6–12 inches), and height limits (usually 4–6 feet residential). Call your city's planning department or check their website; skipping this step can result in fines or a forced removal.
Choose Materials That Match Your Budget and Climate
The material choice drives both cost and longevity.
Wood (Pressure-treated or cedar): $8–$20 per linear foot for materials. Cedar looks nicer and weathers better but costs more upfront. Pressure-treated pine is budget-friendly but requires staining every 3–5 years. Wood suits most residential settings but demands ongoing maintenance.
Vinyl: $20–$40 per linear foot. Lasts 20–30 years with minimal maintenance—just occasional cleaning. Best for humid or coastal climates where wood rots faster. More expensive initial investment but lower lifetime cost.
Metal (Steel or aluminum): $15–$35 per linear foot. Aluminum is lighter and rust-resistant; steel is stronger but needs rust treatment. Good for contemporary aesthetics or high-wind areas.
Composite: $25–$50 per linear foot. Combines wood fibers and plastic for durability without constant upkeep. Overkill for most budgets unless longevity is your priority.
For a 100-foot run, wood might cost $800–$2,000 in materials alone; vinyl could run $2,000–$4,000. Factor in concrete, hardware, and tools on top.
Calculate Post Spacing and Foundation Depth
Posts should be spaced 6 feet apart for most fencing styles. For a 100-foot fence, you'll need roughly 17–18 posts. In areas with heavy frost, bury posts 3–4 feet deep; in milder climates, 2–3 feet is standard. A loose rule: bury 1/3 of the post length.
You'll need:
- Concrete mix (80-lb bags): roughly 2–3 bags per post
- 4x4 or 6x6 posts (depending on fence height and material)
- Post-level tool (essential—wonky posts ruin the whole job)
- Digging tool: rented power auger ($40–$80/day) saves your back on rocky soil
Gather Tools and Estimate Labor Time
Beyond materials, you need basic tools. If renting:
- Power auger: $40–$80/day
- Post-hole digger (manual): $15–$30 purchase
- String line, levels, tape measure, circular saw, drill, adjustable wrench, safety glasses
A typical DIY installation takes 3–5 days for a 100-foot fence, working alone. If you have a helper, cut that by 25–40%. Post installation alone takes about 1 day; panel hanging takes the rest.
Installation Order: Posts First, Panels Last
- Mark and dig post holes using your stakes. Use a string line to keep posts in a straight line.
- Set posts in concrete using a level on two perpendicular sides. Let concrete cure 24–48 hours.
- Attach rails (horizontal support boards) between posts once concrete sets.
- Install panels or boards starting from one end, working toward the other.
Take your time on post alignment—crooked posts make panel installation miserable and the fence looks unprofessional.
Know When to Hire a Pro
If your property has major slopes, rocky soil, or poor drainage, or if the fence spans more than 200 linear feet, professional installation saves headaches. Mercoly helps you compare trusted fencing providers in your area, so you can get quotes and see which jobs are better suited for contractors.
Frequently Asked Questions
Q: Do I need a permit for a backyard fence? Yes, most municipalities require permits for residential fencing. Check local codes before starting; costs range $50–$300 and usually take 1–2 weeks to approve.
Q: What's the best time of year to install a fence? Spring and fall offer mild weather and lower contractor availability if you hire out, but any season works for DIY as long as the ground isn't frozen or waterlogged.
Q: Can I install vinyl fencing myself, or do I need special tools? Vinyl is very DIY-friendly—it requires the same basic tools as wood, though you'll need a hacksaw or circular saw with a fine-tooth blade to cut vinyl panels cleanly.
