Why Most Fence Projects Fail Before They Start
You’d think putting up a fence would be straightforward. Dig some holes, set some posts, attach the panels. Done, right? Not even close. I’ve seen homeowners spend thousands fixing problems that should’ve never happened in the first place.
Here’s the thing — fence installation mistakes don’t always show up right away. Sometimes it takes a year. Maybe two. Then one morning you wake up to leaning posts, sagging gates, or worse, an angry neighbor claiming you’re three feet into their property.
If you’re considering Fence Installation in Porterville CA, knowing these common pitfalls could save you serious money and headaches. Let’s break down what goes wrong and how to avoid it.
Mistake #1: Shallow Post Holes
This one kills me. People dig post holes maybe 18 inches deep and call it good. Then they’re shocked when their fence starts wobbling after the first big windstorm.
The general rule? Your post should be buried about one-third of its total length. For a 6-foot fence, that means digging down at least 2 feet. In areas with freeze-thaw cycles, you might need even deeper to get below the frost line.
Why It Gets Expensive
Fixing shallow posts means digging them up completely, removing old concrete, and starting over. We’re talking $50-100 per post just in labor, plus materials. A 100-foot fence could easily have 15-20 posts. Do the math — that’s ugly.
Mistake #2: Skipping the Property Survey
You think you know where your property line sits. Your neighbor thinks they know too. Turns out, you’re both wrong. And now there’s a brand new fence sitting partially on their land.
According to property survey guidelines, boundary disputes are among the most common reasons for fence removal and reinstallation. Legal fees, surveyor costs, and rebuilding can easily hit $5,000 or more.
The Simple Fix
Spend $300-500 on a professional survey before you build anything. That investment looks pretty smart compared to tearing down and rebuilding an entire fence line.
Mistake #3: Wrong Concrete Mix or Curing Time
Concrete isn’t just concrete. Using the wrong mix or not letting it cure properly creates weak anchor points. I’ve seen posts pull right out of the ground because someone got impatient and started hanging panels too soon.
Standard concrete needs at least 48-72 hours to set properly. Fast-setting mixes cut that time, but you still need to follow the instructions. Skipping this step basically guarantees problems down the road.
Mistake #4: Ignoring Drainage Patterns
Water and fences don’t play nice together. If you install a solid fence that blocks natural drainage, you’re creating a dam. Water pools, soil erodes, posts rot faster, and your neighbor’s yard floods.
What Actually Happens
- Wood posts saturated in standing water rot within 3-5 years
- Metal posts in waterlogged soil rust from the bottom up
- Soil erosion undermines fence stability
- Neighbor complaints about redirected water flow
Gate Installation Services in Porterville CA professionals often recommend gaps at ground level or French drains along fence lines to manage water flow properly.
Mistake #5: Incorrect Post Spacing
Trying to save money by spreading posts further apart is tempting. But there’s a reason standard spacing exists — usually 6 to 8 feet depending on material type.
Go wider and your panels sag. Wind loads stress connection points. The whole structure becomes weaker. For wood fences, 8 feet is pretty much the max. Chain link can sometimes handle more, but not by much.
Mistake #6: Using the Wrong Hardware
Galvanized screws in coastal areas? They’ll corrode in a couple years. Regular steel brackets in wet climates? Rust city. Undersized hinges on heavy gates? Good luck with that.
McCool Welding Inc. recommends matching hardware to both your fence material and local environmental conditions. Stainless steel costs more upfront but outlasts cheaper alternatives by decades.
Hardware Problems to Watch For
- Zinc-coated hardware failing in salt air environments
- Wood screws splitting fence boards
- Hinges too small for gate weight
- Mismatched metals causing galvanic corrosion
Mistake #7: Poor Gate Alignment
Gates get the most abuse of any fence component. They swing open and closed thousands of times. Kids hang on them. Wind catches them. And if they’re not aligned perfectly from day one, problems multiply fast.
A gate that drags on the ground wears out faster. One that doesn’t latch properly becomes a security issue. Gate Installation Services in Porterville CA specialists know that proper alignment during installation prevents 90% of future gate problems.
Mistake #8: Forgetting About Expansion and Contraction
Wood expands when it gets wet. Vinyl moves with temperature changes. Even metal shifts slightly between seasons. Install a fence without expansion gaps and you’ll see buckling, warping, and cracked panels.
Most materials need about 1/8 to 1/4 inch gap between panels. It’s not much, but it makes a huge difference over time.
Mistake #9: Not Checking for Underground Utilities
You know what’s really expensive? Hitting a gas line. Or slicing through buried electrical cables. Or puncturing a water main.
Call 811 before digging. It’s free, and utility companies will mark underground lines. Skipping this step isn’t just expensive — it’s genuinely dangerous. Plus, you’re liable for any damage you cause.
Mistake #10: DIY When You Shouldn’t
Look, some projects are perfect for DIY. A small garden fence? Sure. But a 200-foot privacy fence on sloped terrain with multiple gates? That’s different.
Fence Installation in Porterville CA involves more than most people realize. Ground conditions vary. Slopes require stepped or racked panels. Heavy gates need reinforced posts. Sometimes hiring professionals actually costs less than fixing DIY disasters.
When to Call for Help
- Property has significant slope changes
- You need gates over 4 feet wide
- Soil is rocky or has high clay content
- HOA or local codes have strict requirements
- You’ve never installed fencing before

Frequently Asked Questions
How deep should fence posts be buried?
Generally, bury about one-third of the total post length. A 6-foot fence needs posts buried at least 2 feet deep. In areas with freezing temperatures, dig below the frost line to prevent heaving.
Do I need a permit for fence installation?
Most areas require permits for fences over a certain height, usually 6 feet. Even shorter fences may need permits if they’re near property lines or in front yards. Check local building codes before starting.
How long does concrete need to cure before attaching fence panels?
Standard concrete needs 48-72 hours minimum. Fast-setting mixes can reduce this to 4-6 hours, but full strength takes about a week. Don’t rush this step — it’s the foundation of your entire fence.
What causes fence posts to lean over time?
Common causes include shallow installation, inadequate concrete, poor drainage, soil erosion, and using undersized posts for the fence weight. Frost heave also pushes posts out of alignment in colder climates.
Is it cheaper to repair or replace a damaged fence?
Depends on the damage extent. If more than 30-40% needs work, replacement often makes more financial sense. Patching old, weathered fencing with new materials also creates mismatched appearance and potential structural issues.
