7 Mistakes You’re Making with Fence Installation in Montgomery County (and How to Fix Them)
When you decide to put up a fence around your home in Clarksville, TN, you usually have one of three things in mind: privacy, keeping the dog from chasing squirrels into the neighbor's yard, or just marking what’s yours. It seems straightforward enough. You buy some panels, dig some holes, and call it a day. But here’s the deal: I’ve seen more "simple" fence jobs turn into expensive headaches than almost any other home project.
In Montgomery County, we deal with rocky soil, sticky summer humidity, and some very specific local codes that catch people off guard. If you get it wrong, you aren't just looking at a wobbly gate. You might be looking at a legal notice from the city or a very angry neighbor. I want to help you avoid the frustration of having to tear down work you just finished.
Here’s what you need to know about the most common fence installation mistakes I see in our area and how to get it right the first time.
1. Eyeballing the Property Line
This is the king of all fencing mistakes. I can't tell you how many times someone has told me, "I just followed the old fence line" or "I figured the yard ended at that row of trees." That’s a dangerous game to play in Clarksville.
If you’re off by even three inches, you’ve technically stolen land from your neighbor. If they decide to sell their house or if they’re just sticklers for the rules, they can legally force you to move that fence. It doesn't matter if you spent $5,000 on it.
What I’d do first:
Don’t guess. Look for your property pins. These are metal stakes buried at the corners of your lot. If you can’t find them, go to the Montgomery County Building & Codes office and get a copy of your plat map. If things are still fuzzy, hire a surveyor. It’s cheaper than rebuilding a fence twice.
2. Ignoring the City vs. County Rules
Whether you live in Sango, St. Bethlehem, or out near Fort Campbell, you need to know exactly whose jurisdiction you’re in. There’s a big difference between building a fence inside Clarksville city limits versus the unincorporated parts of Montgomery County.
Inside the city, if you want a fence taller than 6 feet, you need a permit. Period. I’ve seen folks put up a beautiful 8-foot privacy fence to block out a noisy road, only to have a code enforcement officer knock on their door a week later. In the county, you have a bit more wiggle room, but you still can't just do whatever you want.
Quick tip:
If you’re inside the city, your front yard fence usually can’t be taller than about 3.5 feet if it’s near the street. This is for "sight distance", basically, making sure people can see around corners when they're driving. Check the local zoning before you buy your materials.
3. Forgetting to Call 811
You’d be surprised how many utility lines are buried just a foot or two underground in our neighborhoods. Digging a post hole without knowing what’s underneath is like playing Russian roulette with your internet connection or, worse, a gas line.
I remember a job in St. Bethlehem where a homeowner decided to DIY his fence on a Saturday. He hit a main water line on his third hole. By the time the city got there to shut it off, his backyard looked like a small lake, and he was looking at a massive repair bill from the utility company.
How to fix it:
Call 811. It’s free. They’ll come out and mark your lines with little flags. If you see a yellow flag, don't dig there. It’s that simple.
4. Building Over Easements and Drainage Paths
Even if the land is technically yours, the city or utility companies might have an "easement" on it. This means they have the right to access that land to fix pipes or wires. If you build a permanent fence right over a main sewer line easement, and that pipe bursts, the city is coming through your fence with a backhoe. They aren't going to be careful about your pickets, either.
Then there’s drainage. Clarksville gets those heavy Tennessee rainstorms that turn yards into rivers. If you build a solid privacy fence across a natural drainage path, you’re basically building a dam. You’ll end up with a swamp in your yard and a rot problem at the base of your fence.
What to look for:
Check your plat map for drainage and utility easements. If you have to cross a drainage area, leave a gap at the bottom or use a style of fence that lets water flow through, like a black aluminum or chain link.
5. Setting Posts Too Shallow
Our soil here is a mix of clay and rock. It’s tough to dig in, so a lot of people quit after 18 inches. That’s a mistake. A 6-foot privacy fence acts like a giant sail when those spring winds whip through Montgomery County. If your posts aren't deep enough, that fence is going to lean faster than you can say "storm season."
I recently looked at a fence where the owner had used those "no-dig" spikes because the ground was too hard. Within six months, the whole side of the fence was bowing out toward the street. You could see where the ground had softened up during a rain and the wind just pushed the spikes right over.
Here’s the deal:
You want your posts at least 24 to 30 inches deep. A good rule of thumb is that one-third of the post should be underground. And use concrete. It might be a pain to haul those bags, but it’s the only way to make sure that post stays put.
6. Skipping the HOA Approval
If you live in a managed community in Clarksville, the HOA is your boss when it comes to the outside of your house. They usually have very specific rules about what kind of fence you can have. Some only allow black aluminum; some only allow white vinyl. Almost all of them want to see a plan before you start.
I’ve had to help people tear down perfectly good wood fences because their HOA didn't allow "shadowbox" style, only "dog-ear." It’s frustrating, but those rules are legally binding.
Quick tip:
Send an email to your HOA board before you buy a single board. Get their approval in writing. It saves you a world of stress later.
7. Using the Wrong Materials for Tennessee Weather
We have a lot of humidity here. If you use cheap, untreated wood, it’s going to rot in three years. I’ve seen fences where the knots have already started falling out of the wood after just one season because the boards shrunk so much in the heat.
Another common issue is using the wrong fasteners. If you use standard nails that aren't galvanized or stainless steel, you’ll start seeing those ugly black "tears" running down your wood as the nails rust.
What I’d do:
Use pressure-treated pine or cedar. Cedar is naturally rot-resistant and looks great, though it’s a bit pricier. And always, always use galvanized screws or nails. It keeps the fence looking clean and prevents the boards from popping off when the wood expands and contracts.
Common Causes of Fence Failure in Clarksville
Most fence issues don't happen all at once. They happen slowly. Here are the common culprits I see:
- Soil Erosion: Rain washes away the dirt around the concrete footer, leaving the post unstable.
- Gate Sag: This is usually because the hinge-side post wasn't reinforced or the gate frame didn't have a diagonal brace. I often see "split caulk" where the gate trim meets the post because of this movement.
- Improper Spacing: Pickets are nailed too tight together when wet. When they dry out in the Clarksville sun, they shrink and leave giant gaps you could see through.
Cost Factors for Fence Installation
When I give an estimate for a fence in Montgomery County, I look at a few things:
- Linear Footage: Obviously, the more fence, the more it costs.
- Terrain: If I have to dig through solid limestone (which happens a lot here), it takes longer and costs more.
- Style: A standard dog-ear fence is the most budget-friendly. A horizontal modern fence or a shadowbox takes more labor and material.
- Gates: Every gate adds to the cost because of the extra hardware and the time it takes to get it perfectly level.
How Long Does Installation Take?
For an average-sized backyard in Clarksville, you’re usually looking at 2 to 4 days.
- Day 1: Layout, marking utilities, and digging/setting posts. The concrete needs time to cure.
- Day 2-3: Running the rails and nailing up the pickets.
- Day 4: Building and hanging the gates and doing the final cleanup.
If the weather doesn't cooperate: and we know how Tennessee rain is: it might stretch out another day or two.
Prevention: Keeping Your Fence Standing for 20 Years
If you want your fence to last, you have to maintain it.
- Stain it: Don't just leave the wood raw. A good quality stain protects it from UV rays and moisture.
- Check the hardware: Every spring, walk the line. Tighten any loose screws. If you see a "loose picket," nail it back down before it warps.
- Keep the weed whacker away: Hitting the bottom of your posts with a string trimmer every week will eventually eat through the wood.
When to Call a Pro
If you’re comfortable with a post-hole digger and have a few buddies to help, you can certainly DIY a fence. But if you’re looking at a steep hill, if you’re worried about hitting a utility line, or if you just want it to be perfectly straight and level, it might be time to call someone.

FAQs
Do I need a permit for a fence in Clarksville, TN?
Only if the fence is over 6 feet tall and you are within the city limits. If you are in unincorporated Montgomery County, you generally do not need a permit, but you still must follow easement rules.
Can I build my fence right on the property line?
In Montgomery County, you can build on the property line, but you cannot encroach on your neighbor's side. Most people choose to set the fence back a few inches just to be safe and avoid future disputes.
What is the best wood for a fence in Tennessee?
Pressure-treated pine is the most common and cost-effective. Cedar is better for longevity and resisting rot in our humid climate, though it costs more upfront.
How deep should fence posts be in Clarksville?
Because of our wind and soil conditions, I recommend at least 24 inches for a standard 6-foot fence. If you hit solid rock, you may need to use a rock drill or a different anchoring method.
Should I stain my new fence immediately?
If you use pressure-treated wood, wait a few weeks for it to "dry out" so the stain can actually soak in. If you use cedar, you can usually stain it much sooner.
How do I prevent my gate from sagging?
Use a heavy-duty post for the hinge side, set it deeper in concrete, and always use a diagonal cross-brace on the gate frame itself.
