Why a Fence
A fence serves multiple purposes: privacy (blocking views from neighbors and passersby), security (keeping children and pets safely in the yard), property definition (marking boundaries), noise reduction (solid fences reduce street noise), wind protection (blocking prevailing winds in exposed areas), aesthetics (enhancing curb appeal and landscape design), and increased property value (a well-maintained fence can add 2-5% to home value). Fencing is one of the most common home improvement projects. The choice of material, style, and height depends on your primary goal (privacy, security, decorative), local building codes and HOA requirements, budget, and desired maintenance level.
Materials
Wood (pressure-treated pine): The most popular fencing material in the US. Affordable, versatile, and available in many styles. Pressure treatment resists rot and insects (but does not prevent them entirely). Lifespan: 15-20 years with maintenance (stain or seal every 2-3 years). Cost: $12-$25 per linear foot installed (6-foot privacy fence).
Wood (cedar): Naturally rot-resistant and insect-resistant (no chemical treatment needed). Beautiful natural color (ages to silver-gray without stain). More expensive than pressure-treated pine but longer-lasting. Lifespan: 20-30 years. Cost: $15-$35 per linear foot installed.
Wood (redwood): Premium natural wood with excellent rot and insect resistance. Beautiful red-brown color. The most expensive wood fencing. Lifespan: 25-35+ years. Cost: $25-$50 per linear foot installed.
Vinyl (PVC): Maintenance-free. Never needs painting, staining, or sealing. Will not rot, warp, or attract insects. Available in white, tan, gray, and wood-grain finishes. Higher upfront cost but lower lifetime cost (zero maintenance). Lifespan: 20-30+ years. Cost: $20-$40 per linear foot installed.
Composite: A mix of wood fibers and plastic. Looks like wood but with near-zero maintenance. Available in many colors and wood-grain textures. Cost: $25-$45 per linear foot installed.
Chain link: The most affordable fencing. Durable and low-maintenance. Provides boundary definition and security but no privacy (unless privacy slats are added). Common for back yards, dog runs, and commercial applications. Lifespan: 20-30+ years. Cost: $8-$18 per linear foot installed (4-foot height).
Aluminum/wrought iron: Decorative, open-style fencing. Elegant appearance. Used for front yards, pool enclosures, and decorative purposes. Provides boundary definition but no privacy. Lifespan: 20-50+ years (aluminum does not rust). Cost: $20-$50 per linear foot installed.
Fence Styles
Privacy fence (board-on-board, stockade): 6-foot tall solid fence with no gaps between boards. The most popular residential fence style. Provides complete visual privacy.
Semi-private: Boards with small gaps (1/4-1/2 inch) that allow air flow while limiting visibility. Slightly less material cost and a more open feel than a solid privacy fence.
Picket fence: Short (3-4 feet), with spaced vertical boards (pickets) and decorative tops. Classic American look. For front yards and gardens. Provides boundary definition, not privacy.
Split rail: Horizontal rails in a zigzag or straight-line pattern. Rustic, open look. Common in rural areas and large properties. No privacy or security. Very affordable.
Shadowbox (alternate board): Boards alternate on each side of the rails, creating a pattern that looks finished from both sides. The premium privacy fence style (good neighbor fence — looks equally good from both sides).
Installation
Posts: Set posts every 6-8 feet. Posts should be buried 1/3 of their total length (a 6-foot fence needs 9-foot posts buried 3 feet deep, or 8-foot posts in 2-foot holes with concrete). Concrete-set posts are the strongest (use ready-mix concrete, 1-2 bags per post).
Rails: Horizontal boards that connect the posts and support the fence boards. Typically 2x4 pressure-treated lumber. Two rails for 4-foot fences, three rails for 6-foot fences.
Fence boards: Attached vertically to the rails with screws or nails. Standard dog-ear boards are the most common and affordable.
Gate: Build the gate frame from 2x4s with a diagonal brace (from bottom hinge side to top latch side) to prevent sagging. Use heavy-duty hinges and a self-closing hinge if code requires it (pool fences).
DIY difficulty: Moderate. The hardest part is digging post holes (rent a two-person post hole auger for $50-$100/day) and setting posts straight and at consistent height. Time: 2-4 days for 150-200 linear feet with 2 people.
