Fence Prices

Most residential fences in the Knoxville area fall between $10 and $70 per linear foot installed, depending mostly on the material. Chain link sits at the bottom of that range, pressure-treated wood privacy and vinyl land in the middle, and ornamental aluminum sits at the top. For a typical 150-foot backyard, most residential projects land roughly between $2,100 and $7,500 — before gates.

These are 2026 budgeting estimates, not quotes. Every figure assumes a straightforward job: reasonably flat ground, clear access, no old fence to tear out.

Cost per linear foot by material (2026)

Ranges are wide on purpose. Height, style, material grade, terrain and gate count all move a job within its range: a 4-foot galvanized chain link fence sits near the bottom of the chain link range, and a 6-foot board-on-board privacy fence sits above a dog-ear fence because it uses roughly 30–50% more pickets per foot. Metal prices rose in 2026 because of tariffs on imported steel and aluminum, while lumber held steadier. Figures draw on published cost data from HomeGuide, Angi, HomeAdvisor and Fixr, adjusted for 2026 material pricing. See the full 2026 Knoxville fence cost breakdown.

Gates are priced per unit, not per foot

• Single walk gate: commonly $200 – $800 installed, depending on material and hardware. Chain link is cheapest; ornamental metal is dearest.
• Double drive gate: a wide opening needs heavier posts, heavier hinges and often a drop rod or cane bolt. Manual double gates in wood or chain link are a modest adder; automated entrance gates with an operator run into the thousands.

Gate count matters more than people expect. Two gates on a 150-foot run can add several dollars per foot to the effective price of the whole job, because each gate is a fixed cost spread over the same footage.

What pushes a project to the top of the range

• Rock. Knox County and much of East Tennessee sit on karst — limestone and dolomite bedrock that comes close to the surface in unpredictable places (University of Tennessee, 2019). When an auger hits refusal, holes get finished with rock bits, a hammer drill or a shovel. That is the most common reason a Knoxville fence job costs more than the estimate suggested.
• Slope. Sloped ground means racked or stepped panels, longer posts and more layout time. Published Knoxville data puts slope and rocky terrain together at a 10–25% increase.
• Clay. East Tennessee clay holds water. Posts set in poorly drained clay need proper concrete collars and drainage at the base, which adds material and time per hole.
• Tear-out. Removing and hauling an existing fence typically adds $2–$5 per foot, plus disposal.
• Access. Narrow side yards, mature tree roots, wooded property lines and drainage swales all force hand digging and hand hauling of material.
• Height. Going from 6 feet to 8 feet in wood can roughly double the per-foot cost. Going from 4 to 6 feet in chain link adds a few dollars a foot.
• Post depth. Deeper holes cost more, and depth is not optional — it is what keeps the fence standing.

How deep the rock sits, by soil series

“We might hit rock” is vague until you know which soil your lot is on. These depths come from the NRCS Soil Survey of Knox County, and they are the single biggest reason two neighbors on the same street get different numbers.

A Montevallo lot hits refusal inside the first foot. A Corryton lot digs clean. Same fence, same crew, different day of work. Dewey, Fullerton, Townley and Heiskell series are also common across the county.

Two numbers people get wrong here. Knox County’s adopted frost line is 12 inches — shallow, and not what sets post depth. Depth is driven by overturning load and clay movement, against an adopted design wind value of 90. And the clay that does the moving runs 35 to 60 percent in the subsoil, under about 51.93 inches of rain a year, which is why drainage at the base of a post matters more here than the panel style does.

A worked example

A common Knox County job: back yard enclosed on three sides, 150 linear feet, 6-foot pressure-treated pine privacy, one walk gate, mild slope, good access, no rock.

Change one variable and it moves. Board-on-board instead of dog-ear pushes the fence line toward $5,000–$7,500. Hitting Montevallo rock on a third of the holes adds a day. A double drive gate with an operator can add more than the entire fence above.

On cedar: we do not carry it. It can be sourced by request, but it is expensive here and does not hold up well in East Tennessee clay without special installation. Ground-contact-rated pressure-treated pine is what we recommend and build with — and the money saved goes further in post depth and hardware.

Budget for the utility locate too

It is free, but it takes time. Tennessee 811 requires three working days notice before digging, the ticket is good for 15 days, and there is a 4-foot tolerance zone either side of every marked line. The fence-post exemption people cite is narrow — it only applies outside recorded easements and more than 100 feet from pavement, which rarely describes a Knoxville subdivision lot. Whoever digs carries the obligation; if you hire us, that is us.

Common questions

What is the cheapest fence to install?

Galvanized chain link, starting around $10 per linear foot installed for a basic 4-foot fence. Farm wire is cheaper per foot but is intended for acreage and livestock, not residential yards. See the cheapest fence to install.

Is vinyl worth more than wood?

Vinyl usually costs more up front than pressure-treated wood and never needs staining. Wood costs less to install and can be repaired one board at a time. Which one is cheaper over twenty years depends on how much maintenance you would actually do.

Why do estimates for the same yard differ so much?

Usually post depth, post spacing, hardware grade and whether tear-out and rock are included. Ask every bidder what happens when they hit rock, and get the answer in writing before you compare prices.

Do I need a permit?

It depends on your jurisdiction, height and location on the lot. Height limits and setbacks differ between city, county and HOA rules — in unincorporated Knox County, front-yard fences are limited to 3½ feet under Knox County Zoning Ordinance § 3.20.04. Check with your local codes office before ordering material, or see our fence answers page.
