How Much Does New Siding Cost in East Tennessee? (2026 Guide)
Last Updated: August 28, 2026
Quick Takeaway: If you're looking for a quick number, here's a useful place to start: a full siding replacement in the Knoxville area may cost somewhere around $12,000–$45,000 in 2026. That's a wide range, but there's a good reason for it. Siding costs depend on much more than the size of your house. Material choice, exterior wall area, number of stories, architectural details, access, and the condition of what's hiding behind your current siding can all change the final number.
And one important disclaimer right up front: these are general Knoxville market-planning ranges, not guarantees. At McLain’s, we don't have a standard siding price because, quite frankly, there are too many variables to give homeowners a dependable number without first measuring and inspecting the house.
What Does New Siding Cost in Knoxville in 2026
For homeowners who are still in the "How much should we even be budgeting for this?" stage, these general Knoxville-area ranges can help:
- Full siding replacement: Approximately $12,000–$45,000
- Vinyl siding: Approximately $4–$8 per square foot installed
- LP SmartSide engineered wood: Approximately $7–$11 per square foot installed
- James Hardie fiber cement: Approximately $10–$16 per square foot installed
These numbers are best used for early planning, not as a substitute for an estimate.
Keep in mind, siding isn't strictly priced by taking the square footage of your house, multiplying it by a number, and calling it a day. If only home improvement projects were that cooperative.
What Actually Determines the Price of a Siding Project?
There are a lot of moving pieces here. Some are obvious, like the siding material you choose. Others don't become apparent until someone takes a closer look at the house.
The Amount of Exterior Wall You Actually Have
Interior square footage isn't the same as siding area. The exterior needs to be measured based on the home's shape, gables, windows, doors, and other architectural features.
How Tall and Complicated the House Is
A simple one-story home is generally easier to side than a taller home with multiple rooflines, dormers, and corners. More complexity can mean additional labor, equipment, and difficult access.
The Siding You Choose
Material makes a big difference in price. Vinyl is generally the most budget-friendly, followed by LP SmartSide, while James Hardie typically costs more. Appearance, maintenance, and durability should factor into the decision too.
Removing the Existing Siding
Old siding may need to be removed before the new material goes on. The labor and disposal involved can add to the overall project cost.
What's Hiding Behind the Siding
Rot, water damage, termites, or damaged sheathing aren't always visible until the old siding comes off. If problems are uncovered, they'll need to be repaired before the new siding is installed.
How Much Does It Cost to Side a 2,000-Square-Foot House?
We see this question a lot, and there's one problem with it: 2,000 square feet of living space doesn't equal 2,000 square feet of siding. Imagine two 2,000-square-foot homes. One is a sprawling single-story ranch. The other puts roughly the same living space into two stories. Their exterior dimensions aren't going to be identical, even though both may be advertised as 2,000-square-foot houses.
Now add gables, windows, doors, trim, and architectural details into the equation.
That's why we wouldn't want to give someone a siding quote based solely on interior square footage. The exterior walls need to be measured, and the house itself needs to be evaluated before an accurate price can be established.
Is Wood Siding Cheaper Than Vinyl Siding?
Usually not.
Traditional wood siding generally costs more than vinyl siding upfront and also asks a little more from you over the years. Wood needs ongoing protection from East Tennessee's sun, rain, and moisture, which typically means periodic painting or staining along with keeping an eye out for deterioration. Vinyl generally costs less and requires less routine maintenance. Already have wood siding? See our article on wood rot and painting here.
That doesn't mean everyone should automatically choose vinyl. Plenty of homeowners love the character of real wood and consider the added cost and maintenance worthwhile. It's more a question of what you value and how much maintenance you're willing to take on.
Can You Get Siding That Looks Like Wood?
Yes, and you have more options than you might think. LP SmartSide is an engineered wood siding product designed to offer the warmth and texture homeowners often associate with traditional wood siding. James Hardie fiber-cement siding is also available in wood-grain textures that can create a similar visual effect.
They're very different products, so choosing between them shouldn't come down to appearance alone. Price, maintenance, installation, durability, and the specific needs of your home should all be considered. But if your goal is "I want it to look like wood without actually using traditional wood siding," you're definitely not out of luck.
The Takeaway: A Realistic Siding Budget for an East Tennessee Home
If you're in the early stages of planning, $12,000–$45,000 is a useful general market range for a full siding replacement in the Knoxville area in 2026. Like we’ve been saying, that's a wide range. But thankfully it's not hard to narrow those numbers down. Reach out to a local contractor and have them come out and take a look around. It's a simple process that shouldn't involve any fees, pressure, or contracts. All it takes is one visit and you’ve got a concrete number.

Frequently Asked Questions
Do I need to replace all of my siding, or can you repair damaged areas?
McLain’s handles both full siding replacements and localized repairs. If the damage is limited, repairing the affected area may be the better option.
Can you paint my existing siding instead of replacing it?
Yes. If your siding is still structurally sound but looks faded or worn, painting may be a more cost-effective option than replacement.

Do you use subcontractors for siding projects?
No. McLain’s uses full-time employees rather than outsourcing siding projects to subcontractors, keeping the work with one team and one point of contact.
How long does siding replacement take in Knoxville?
A typical full-home siding replacement can take around one to three weeks, depending on the home's size, complexity, and weather. Smaller repairs may take only a few days.
