What St. Louis Homeowners Are Actually Paying for Siding Installation
Siding installation st louis prices typically fall in these ranges depending on material:
| Material | Cost Per Sq Ft (Installed) | Typical Full-Home Cost |
|---|---|---|
| Vinyl (mid-grade) | $3.35 – $12.34 | $6,192 – $14,763 |

The St. Louis average across all materials is around $9,680 – about 12% below the national average of $11,000. That’s good news. But prices have risen nearly 18% since 2020, so knowing what’s fair before you call a contractor matters more than ever.
Getting siding quotes can feel overwhelming, especially when you’re already dealing with storm damage or a home that’s showing its age. Prices vary widely depending on material, home size, and which contractor shows up at your door.

Average siding installation st louis prices by Material
When we talk about siding installation st louis prices, the material you choose is the single biggest “dial” you can turn to adjust your budget. In the Gateway City, we see a wide variety of architectural styles, from the historic brick-and-siding combos in South City to the sprawling modern builds in O’Fallon and Chesterfield.
To get an accurate picture, you have to look at both the material cost and the labor required to hang it. Some materials, like vinyl, are lightweight and snap together quickly. Others, like fiber cement, are heavy, require specialized cutting tools, and need a larger crew to handle the boards without breaking them.
| Material Type | Material Cost (per sq ft) | Labor Cost (per sq ft) | Total Installed (per sq ft) |
|---|---|---|---|
| Standard Vinyl | $2.50 – $4.50 | $2.00 – $4.00 | $4.50 – $8.50 |
| Insulated Vinyl | $4.00 – $6.50 | $3.00 – $5.50 | $7.00 – $12.00 |
| Fiber Cement | $5.00 – $9.00 | $4.00 – $7.00 | $9.00 – $16.00 |
| Engineered Wood | $4.50 – $8.00 | $3.50 – $6.00 | $8.00 – $14.00 |
| Metal (Aluminum/Steel) | $3.00 – $6.00 | $3.00 – $5.00 | $6.00 – $11.00 |
While St. Louis prices are generally lower than the national average due to a more competitive local market and lower cost of living, our local sales tax—which can hit 9.68% in some parts of St. Louis County—can add a surprising chunk to your material bill. To get a better feel for your specific project, you can use a 2026 Siding Cost Estimator to see how these variables play out.
Vinyl siding installation st louis prices per Square Foot
Vinyl remains the king of the Midwest for a reason: it’s incredibly cost-effective. For a mid-grade vinyl project, you’re looking at an average of $3.35 per square foot for the installation itself, though the full “installed” price (materials + labor) usually ranges from $7.23 to $12.34 depending on the thickness and style.
There are many benefits of vinyl siding installation beyond just the price tag. Modern vinyl doesn’t look like the “plastic” siding of the 1970s. We now have options that mimic the deep grain of cedar or the smooth finish of painted wood. With a 30-40 year lifespan and virtually zero maintenance (just a quick power wash once a year), it offers a fantastic value proposition for families in Florissant or St. Peters who want a beautiful home without a weekend chore list.
Premium Materials: Fiber Cement, Wood, and Metal
If you’re looking for “forever” siding, premium materials are where the conversation goes. James Hardie fiber cement is the gold standard here. In St. Louis, James Hardie lap siding typically starts at $9.00 and can go up to $15.00 per square foot installed. For a standard 1,500 sq. ft. home, this often translates to an $18,000 to $22,500 investment.
Why the premium? Fiber cement is engineered for our specific climate. The James Hardie HZ10 line is designed specifically for regions like ours with high humidity and intense freeze-thaw cycles. It won’t rot, it’s fire-resistant, and termites won’t touch it.
LP SmartSide (Engineered Wood) is another local favorite, priced slightly lower than Hardie at $8 to $14 per square foot. It’s famous for its impact resistance—a huge plus when those St. Louis hailstorms roll through in the spring. Aluminum and steel siding are also viable options, offering a sleek, modern look and excellent durability for roughly $4.21 to $5.35 per square foot, though they are less common in residential neighborhoods than they used to be.
How Home Size and Architecture Impact Your Total Cost
A common mistake we see homeowners make is calculating their budget based on their home’s floor square footage. If you have a 2,000-square-foot house, you don’t have 2,000 square feet of siding. You have to measure the exterior wall area. A two-story home with high ceilings will have significantly more “siding square footage” than a sprawling ranch-style home with the same interior floor space.
Architecture also plays a massive role in siding installation st louis prices. A simple “box” house is easy to side. However, if your home has:
- Multiple stories requiring scaffolding
- Complex gables and dormers
- Turrets or curved walls
- Difficult access (like a house built on a steep hill or very close to a neighbor’s fence)
…your labor costs will climb. Extra cutting, fitting, and safety equipment can add 10% to 25% to the total labor bill.
Estimating siding installation st louis prices for Your Home Size
To give you a rough “ballpark” for a full replacement in the St. Louis metro area (including tear-off and basic trim), here is what we typically see:
- 1,000 sq. ft. Exterior Wall Area: $7,200 – $12,300 (Vinyl) | $9,000 – $15,000 (Fiber Cement)
- 1,500 sq. ft. Exterior Wall Area: $10,800 – $18,500 (Vinyl) | $13,500 – $22,500 (Fiber Cement)
- 2,000 sq. ft. Exterior Wall Area: $14,400 – $24,600 (Vinyl) | $18,000 – $30,000 (Fiber Cement)
- 2,500 sq. ft. Exterior Wall Area: $18,000 – $30,700 (Vinyl) | $22,500 – $37,500 (Fiber Cement)
If you’re unsure if it’s time to spend this kind of money, check out these 10 reasons you may need a siding replacement to see if your current exterior is still doing its job.
Architectural Complexity and Labor Rates
Labor in Missouri generally runs between $2 and $8 per square foot. In the St. Louis market, expect to pay on the higher end of that range if you live in a historic district or a neighborhood with strict HOA guidelines that require specific installation techniques.
Contractor fees for specialized trim work or repairs often range from $70 to $120 per hour. If your home has intricate eaves or requires custom-bent aluminum flashing around unique window shapes, those hours add up. We always recommend getting a detailed line-item quote so you can see exactly how much you’re paying for the “tricky” parts of your home’s design.
Hidden Costs and Local Factors in the St. Louis Market
The “sticker price” of siding is rarely the final price. There are several factors specific to our region that can move the needle. For instance, St. Louis city and county have specific permitting requirements. While a simple repair might not need one, a full replacement usually does. Expect permit fees to range from $100 to $500 depending on the project value.
Then there’s the “St. Louis Tax.” Our combined sales tax is among the highest in the state, often hovering around 9.68%. When you’re buying $10,000 worth of James Hardie boards, that’s an extra $968 just in taxes that many national “online calculators” forget to include.
Local Regulations and St. Louis Climate Challenges
Our weather is… unique. We get 42 inches of rain a year, humid summers that breed mold, and winters that can swing from 60 degrees to 5 degrees in a single afternoon. This makes a high-quality Water-Resistive Barrier (WRB), often called house wrap, non-negotiable.
Installing house wrap and sealing it with high-grade tape adds a layer of protection against the moisture that causes rot and structural damage. While it adds a few hundred dollars to the project, it’s the only thing standing between our Missouri humidity and your home’s wooden skeleton.
Replacement vs. Siding Over Existing Material
You might hear a contractor suggest “siding over” your old wood or vinyl to save money. This usually saves about $1,000 to $3,000 in removal and disposal fees. We strongly advise against this.
Siding over old material is like putting a clean shirt over a dirty one. It hides problems like rot, insect damage, or mold rather than fixing them. Furthermore, most premium manufacturers like James Hardie will void your warranty if the product is installed over old siding. Tearing off the old stuff allows us to inspect the sheathing, replace any rotted wood, and ensure your home is structurally sound.

Strategies to Beat High Siding Prices and Maximize ROI
If you want to beat the average siding installation st louis prices, timing is everything. Most people think about siding in the summer. Because demand is high, prices stay high, and schedules are booked months out.
To save 5-10%, try scheduling your project for the “off-season.” In St. Louis, this is typically March-April or October-November. Contractors are often looking to fill their schedules during these transition months and may offer better labor rates or material discounts to win the job.
Another way to save is to look at the long-term math. While insulated vinyl costs more upfront, siding replacement can boost energy efficiency, saving you 5-15% on your monthly Ameren or Spire bills. Over 20 years, that “expensive” siding can actually pay for itself.
Maximizing Your Return on Investment
Siding is one of the best home improvements you can make for resale value. In the St. Louis market, you can expect a 60-79% Return on Investment (ROI). If you spend $15,000 on new siding, your home’s value could increase by $10,000 or more immediately.
To get the highest ROI:
- Choose Neutral Colors: Grays, beiges, and soft blues perform best for resale in neighborhoods like Maryland Heights and Chesterfield.
- Don’t Skimp on Trim: New soffit and fascia make the whole house look “finished” and high-end.
- Use Factory-Trained Installers: Proper installation ensures the warranty stays valid, which is a huge selling point for future buyers.
Frequently Asked Questions about St. Louis Siding
How long does a typical siding installation take in St. Louis?
For an average 1,500 to 2,000 sq. ft. home, a full replacement usually takes 7 to 14 days. This timeline includes tearing off the old siding, prepping the walls, installing the house wrap, hanging the new siding, and finishing the trim. Weather is the biggest wild card—St. Louis thunderstorms can easily push a project back by a few days.
Is James Hardie siding worth the extra cost in Missouri?
In our opinion, yes—especially if you plan to stay in your home for more than five years. Its resistance to fire, termites, and the intense Missouri humidity makes it incredibly durable. Plus, it holds paint much longer than traditional wood, meaning you won’t be repainting every few years. For more details on the trade-offs, read our guide siding with the best-a guide to exterior pros and cons.
What additional fees should I budget for?
Beyond the siding itself, keep an eye on:
- Asbestos Testing: if your home was built before 1980, testing costs $90-$180.
- Structural Repairs: discovering rot under old siding can add $500 to $2,000 to the bill.
- Disposal Fees: hauling away old material usually costs $200 to $500.
