Planning Your Fence

A well-built fence adds privacy, security, and curb appeal to your property. Before installing a fence, check your local zoning ordinances and HOA rules for height restrictions, setback requirements, and material limitations. Most residential fences are limited to 6 feet in the backyard and 3-4 feet in the front yard. You may also need a building permit. Check with your local building department before purchasing materials.

Property lines must be accurately identified before building. A professional survey is the most reliable method. Many homeowners mistakenly assume their fence is on the property line when it is actually 1-2 feet off. This can lead to disputes with neighbors and costly relocation. Once the property line is confirmed, mark it with stakes and string. Use our Fence Calculator to estimate materials and costs.

Choosing Fence Materials

Pressure-treated wood is the most popular fence material because of its low cost and natural appearance. Cedar and redwood offer superior rot resistance without chemical treatment but cost more. Vinyl fencing is more expensive upfront but requires no painting or sealing and lasts 20-30 years. Chain-link fencing is the most economical option for large areas and provides security without privacy. Aluminum and steel fencing offer a decorative option for front yards.

Wood fences require maintenance every 3-5 years (staining or sealing) and have a lifespan of 15-20 years depending on the species and maintenance level. Vinyl fencing requires only occasional cleaning with soap and water. Chain-link fencing lasts 15-20 years with no maintenance but provides limited aesthetic appeal. Your choice depends on your budget, desired appearance, and how much maintenance you are willing to perform.

Fence installation

Installation Basics

Post placement determines the quality of the entire fence. Set corner and end posts first, then run a string line between them to align the remaining posts. Posts are typically spaced 6-8 feet apart. Dig post holes at least 36 inches deep (below the frost line in cold climates) and 8-12 inches in diameter. Set posts in concrete for maximum stability, using at least one 80-pound bag per post hole.

Plumb each post in both directions and brace it while the concrete sets. Use a string line and level to ensure all posts are aligned at the same height. After the concrete cures (24-48 hours), attach the rails (horizontal members) between posts. For a 6-foot fence, use three rails evenly spaced. Finally, attach the pickets, maintaining consistent spacing using a spacer board.

Gate Construction

Gates are the weakest point of any fence because they are suspended from one side. Use 4x4 posts for gate posts (rather than the standard 2x4 or 3x4) and set them in extra-deep concrete footings. The gate frame should be braced diagonally to prevent sagging. Anti-sag hardware (a tension rod or cable system) can be added later if the gate begins to droop. Position gate latches at a comfortable height (typically 36-42 inches from the ground) and make sure the gate swings freely without binding on the frame.
