6 Common Fence Installation Mistakes (and How to Avoid Them)

Build It Right the First Time

A fence looks simple from the curb — posts, rails, pickets, done. But a lot can go wrong between the dig and the last picket, and in North Texas the consequences show up fast. Within a few seasons you’ll see whether the crew that built your fence understood our soil and our heat, or just put up boards and moved on. The good news is that almost every common failure traces back to a short list of avoidable mistakes. Here are the six we see most often across North Dallas — what each one is, why it fails here, and how it should be done instead.

1. Driven or Shallow Wood Posts in Expansive Clay

The most damaging mistake happens entirely below the ground line: wood posts driven straight into the dirt or buried in shallow, undersized holes. North Dallas sits on Blackland Prairie expansive clay, which the Texas A&M AgriLife Extension notes swells when wet and shrinks when dry — the same force that cracks home foundations. A buried wood post does two things wrong in that soil: it rots at the ground line where moisture sits, and it gets heaved out of plumb every time the clay moves. The fix is to take wood out of the ground entirely. We set hidden U-channel steel posts wet-set in concrete: steel doesn’t rot, the wet-set footing anchors it in the clay, and the cedar still mounts over the top like a normal wood fence. If you want the full breakdown, see our guide on steel vs. wood posts.

2. Using Green or Wet Lumber

Cedar that goes up still green or soaked with moisture is a problem waiting to happen. As that lumber dries out in the Texas sun, it loses water unevenly — and that’s when boards twist, cup, and pull their fasteners loose. The result is a fence that looked perfect on install day and looks wavy by mid-summer. The same thing happens with the wrong species: treated pine is especially prone to it, which we cover in why treated pine warps. The fix is to build with high-quality cedar that’s properly dried before it goes up, so the boards have already done most of their shrinking and stay flat through our seasonal swings.

3. Skimpy or Dry-Packed Footings

Even with the right post, the footing can sink the whole job. Two shortcuts show up constantly: holes that are too small or too shallow, and concrete that’s dry-packed — poured in as dry bag mix and left to cure on ground moisture instead of being mixed first. Both leave you with a weak, inconsistent anchor, and in expansive clay a weak footing gets heaved and twisted out of plumb in a few seasons. The fix is a properly sized, wet-set footing: concrete mixed to the right consistency and poured around the post so it cures into one solid block. We break down exactly why this matters in North Texas soil in dry-pack vs. wet-set fence posts.

4. Skipping the Permit and HOA Approval

It’s tempting to just start building, but skipping the paperwork can cost you a teardown. Many North Dallas cities require a permit for a new fence, and most neighborhoods have an HOA with rules on height, materials, and setbacks. Build without checking, and you risk a stop-work order, a fine, or being told to take it down and start over. The City of Celina publishes its permit and right-of-way requirements, and other cities have their own. The fix is to handle the paperwork before the first hole is dug. We help homeowners navigate permits and HOA approval as part of the job — our fence permit guide walks through what’s typically required.

5. Cheap Gate Hardware and Unbraced Frames

The gate is the hardest-working part of any fence, and it’s usually the first thing to fail. A gate frame with no diagonal bracing slowly racks under its own weight until it drags on the ground; pair that with flimsy hinges and a bargain latch, and you’ve got a gate that sags, sticks, and won’t close within a year. We dig into the mechanics in why your fence gate sags. The fix is to build the gate like it’s meant to last: steel-reinforced, properly braced frames with quality hinges and hardware sized for the gate, so it swings true and latches cleanly for years.

6. Hiring the Lowest Bid

The cheapest quote almost always hides one of the mistakes above — wood in the ground, a dry-packed footing, green lumber, or a gate thrown together without bracing. Those corners are invisible the day the fence goes up and obvious a few seasons later, which is exactly why they get cut. The fix isn’t to chase the highest price; it’s to vet the contractor. Make sure they’re licensed and insured, ask specifically how they set their posts (you want steel set in concrete, not wood in dirt), confirm they build gates with bracing and real hardware, and ask what warranty backs the work. At Picket Pros, every fence is built on hidden steel posts wet-set in concrete and backed by a 1-year workmanship warranty. You can see how we approach a build on our fence installation page.

The Bottom Line

None of these mistakes are exotic — they’re the everyday shortcuts that make a fence cheaper to build and faster to fail. Avoid all six and you end up with the same thing every time: a straight, solid fence that shrugs off North Texas clay and heat for decades. When you’re comparing quotes across North Dallas, ask the hard questions about what happens below the ground line and inside the gate frame. The answers tell you everything about how long the fence will last.
