What Am I Missing?

Over the years, we at Buy Direct Vinyl Fence have seen it all. From answering countless questions to helping homeowners fix fence installation disasters, one thing has become clear: Many of the biggest problems come down to skipping important steps during installation. The truth is, vinyl fencing is one of the most durable, beautiful, and low-maintenance options out there, but only when installed correctly. That’s why we provide step-by-step instructions, how-to videos, and expert coaching to help our customers do it right the first time. Still, we see common mistakes pop up again and again. Let’s break them down so you can avoid them on your own project.

Installation Mistakes

Skipping Layout and Measurements

One of the worst mistakes is simply “eyeballing it.” If you don’t take the time to use string lines, stakes, and spray paint to properly mark your layout, your fence can end up looking uneven, crooked, and unprofessional.

Improper Post Depth or Spacing

Posts are the backbone of your fence. They should be set 24–36 inches deep and spaced 72” or 96” in the center. Shallow or unevenly spaced posts will lead to leaning, sagging, and instability.

Not Calling 811 to Mark Utility Lines

This step is not optional–it's a safety requirement. Call 811 at least 2–3 days before digging. Hitting a gas or electrical line can result in costly repairs, liability, or even serious injury.

Not Checking Property Lines or Permits

Installing a fence on your neighbor’s property can lead to legal battles and expensive removal costs. Always check with your city or HOA before starting.

Inconsistent Post Height

Without a string line at the top and bottom of your fence run, your posts will end up uneven. This makes your entire fence line look crooked and sloppy.

Incorrect Concrete Setting

Concrete should be poured just below ground level and given time to fully cure before assembly. If it’s rushed, your posts will loosen, causing sagging.

Privacy Fence U-Channel Mistakes

We provide three screws for every U-channel to keep panels locked in place. Skipping this step allows panels to warp or pop out.

Measurement & Alignment Errors

Not Accounting for Expansion and Contraction

Vinyl expands and contracts with temperature changes. Without a ¼” gap between rails and U-channels, your fence will warp or buckle.

Failing to Keep Posts Plumb

Even a small tilt becomes a big problem across long fence runs. Misaligned posts also interfere with gate operation.

Not Following Manufacturer Spacing Guidelines

Our fences are designed for 72” or 96” spacing. Ignoring this can lead to poor fit or structural issues. If panels are too tight, trim them—don’t force them.

Component Issues

Improper Rail Insertion

Our Route-Loc® system uses notched rails that fit into routed posts. If not fully seated or locked, panels will eventually pull out. For added strength, add a high-top screw inside the post.

Poor Gate Installation

Gates are often the first thing to fail. To prevent sagging, gate posts must be set at least 24” deep with a stiffener or concrete reinforcement. Proper hardware is also essential for smooth operation.

Mixing Brands or Components

Not all vinyl fence parts are interchangeable. Mixing brands can lead to gaps, mismatches, and weak connections. Always stick with Buy Direct Vinyl Fence components for the best fit and durability.

Environmental Oversights

Ignoring Slope or Grade Changes

Flat panels on a slope will leave large gaps at the bottom. Our panels are designed to rack up to 5% (5 inches per 8 feet) without modification. Steeper grades require trimming and enlarging post holes.

Setting Posts in Wet or Poor Soil

Poor soil leads to leaning posts over time. Always add gravel and ensure proper drainage in the base of your holes.

Planning & Maintenance Oversights

Not Reading Instructions

This one is simple: Read the instructions. We provide written guides, videos, and expert advice from our team to help you succeed. Skipping instructions often leads to preventable mistakes.

No Maintenance Plan

While vinyl fences are low-maintenance, it still benefits from occasional cleaning and inspection, especially after storms. A quick rinse can keep your fence looking brand new for years.
