Common Fence Mistakes

Common Mistakes to Avoid When Installing a Fence

Putting in a fence might seem straightforward, but even small missteps can lead to big headaches down the line. Whether you’re building for privacy, security, or curb appeal, here are some of the most common fence installation mistakes—and how to avoid them.

1. Not Checking Property Lines

One of the biggest (and most expensive) mistakes is installing a fence on your neighbor’s property. Always check your survey or hire a professional to mark the property lines before you dig.

2. Skipping the Permit

Some areas require permits for fences over a certain height, or they may have rules about materials, placement, and visibility. Failing to get a permit can lead to fines or forced removal. Call your city or county before starting.

3. Poor Post Installation

Fence posts are the foundation of your entire structure. Setting them too shallow or without proper concrete can lead to leaning, sagging, or complete collapse over time. Most posts should be buried at least one-third of their height and set in gravel and concrete.

4. Ignoring the Grade

If your yard isn’t flat, you’ll need to decide between stepping or sloping the fence. Ignoring the slope can leave unsightly gaps or uneven panels, compromising both looks and function.

5. Choosing the Wrong Wood

Using untreated or low-quality wood to save money can backfire. Cheap wood is more prone to rot, insects, and warping. Always choose a wood suitable for outdoor use—like cedar, redwood, or pressure-treated pine.

6. Not Planning for Gates

It’s surprisingly common to finish a beautiful fence—only to realize there’s no convenient access point. Plan where gates will go, and ensure they’re wide enough for things like lawnmowers or trailers.

7. Poor Fastening

Using the wrong screws or nails can lead to rust, loose boards, or splitting wood. Use exterior-grade fasteners and space them evenly for both strength and aesthetics.

8. No Room for Expansion

Wood expands and contracts with the weather. If you install boards too tightly together, they can warp, crack, or buckle. Leave small gaps to allow for movement.

A well-built fence adds value and function to your home, but cutting corners or skipping details can cost you. Plan carefully, use the right materials, and follow local regulations to make your fence a long-lasting success.
