What Homeowners Don't Know About DIY Fence Installation (And Why It Usually Costs More)

Every spring, Lancaster County homeowners head to the big box store, load up a trailer with fence panels and posts, and spend a weekend trying to install their own fence. Some pull it off. Most end up with a fence that leans, shifts, or has to be redone within a few years — and spent more than they expected getting there.

We're not going to tell you not to DIY. But we do want you to go in with clear eyes about what's actually involved, because most of the surprises aren't obvious until you're already mid-project.

1. Digging Post Holes Is Harder Than It Looks in Central PA

Lancaster County's terrain is beautiful — and brutal for post holes. If you've never driven a post through Lancaster County soil before, here's what you may be dealing with:

• Limestone and shale bedrock — common throughout the region, sometimes just 12–18 inches below the surface. A standard rental auger will stop dead when it hits it.
• Tree roots — mature trees have root systems that can extend 20–30 feet from the trunk. Roots that size don't move for a hand digger or a light auger.
• Clay soil — heavy clay doesn't release an auger easily, and it expands when wet and contracts when dry, which causes posts to heave over time if not set deep enough with the right concrete mix.
• Rocky fill areas — older properties especially can have decades of fill dirt with rubble, old concrete, and debris just below the surface.

Professional installers carry equipment designed for these conditions — hydraulic augers, breaker bars, and the experience to know when to change approach. A rental auger from Home Depot is built for the easy jobs.

2. You'll Pay Retail — We Don't

This is the one most homeowners don't fully appreciate until they price out materials. When you buy fence panels, posts, concrete, hardware, and gates at a big box store, you're paying retail markup on every item. We buy materials wholesale through a dealer account, which means we pay a fraction of what's on the shelf at Lowe's.

That cost difference often closes — or eliminates — the labor gap between DIY and professional installation. In many cases, your all-in cost for a DIY fence is close to or higher than what we'd charge for a professional installation with a warranty.

3. No Warranty — On Anything

When Shepherd Fencing installs your fence, every installation comes with our 2-year workmanship warranty. If a post shifts, a panel cracks, or a gate sags due to installation error, we come back and fix it. No questions, no charge.

When you DIY, there's no workmanship warranty — because there's no contractor. And the manufacturer warranty on fence materials typically covers defects in the product itself, not installation issues. A post that wasn't set deep enough isn't a product defect. Neither is a panel that pulled out of a rail because the fit wasn't tight.

A fence that lasts 20+ years is one that was set properly from the start. That's harder to guarantee when you're doing it yourself for the first time.

4. The Equipment List Is Longer Than You Think

A proper fence installation requires more than posts, panels, and a post hole digger. Here's what a professional crew shows up with that most homeowners don't have:

• Hydraulic or gas-powered auger (and the truck to haul it)
• Breaker bar and digging bars for rocky soil
• Transit level or laser level for consistent post height
• String line and batter boards for straight runs
• Concrete mixer or mechanical mixing equipment
• Post driver for temporary bracing during cure
• Proper saw setup for cutting panels to fit

You can rent some of this. But rental fees add up, transport takes time, and using unfamiliar equipment on a job with a narrow margin for error adds risk.

5. The Permit and Property Line Issues

Most Lancaster County municipalities require a permit for fence installation. Homeowners doing their own work often skip this step — and end up with a fence that fails inspection or has to be moved. We pull permits on every job we do, and we verify property lines before we set the first post.

Installing a fence even 6 inches over your property line can create legal issues with neighbors and force a costly removal. We use your property survey and, where needed, coordinate with a surveyor to make sure every post goes in the right place.

So When Does DIY Make Sense?

We'll be straight with you: some DIY fence projects do work out fine. A simple split rail fence on flat, open ground with easy soil is a reasonable weekend project for a capable homeowner. A 4-post garden enclosure with basic picket fence panels — also manageable.

Where DIY tends to go sideways: long privacy fence runs, sloped terrain, rocky or rooted soil, vinyl or aluminum that has to be cut to fit, and anything requiring a permit. Those are the jobs where the gap between a DIY result and a professional result is most visible — and most expensive to fix.
