How Much Does Fiber Cement Siding Cost?

So, you’re interested in replacing your home's siding with fiber cement siding and want to know how much it costs.


Chances are you’re familiar with popular San Antonio fiber cement siding manufacturers, like James Hardie and Allura, and know that they aren’t the cheapest option on the market. While they are more expensive options, their cost reflects in the product's performance, durability and longevity.


At Southwest Exteriors, we exclusively install James Hardie fiber cement siding. This is because of its proven quality and ability to withstand the harsh South Texas climate. Although we only offer James Hardie, we aren't here to convince you to choose it for your project. Our goal is to fully educate you on the facts, so you can have the right information to make the best decision for your needs.


Fiber cement siding is an investment. If this is the product you are interested in for your home, expect a higher cost for a professional installation than other types.


In 2023, fiber cement siding costs around $35,000 - $45,000 for 1,500 square feet of siding. This is a standard cost for professional installation and does not include soffit or fascia replacement.


If you are looking for the least expensive fiber cement option, you can buy siding yourself at big-box hardware stores for about $3,000 - $5,000 for 1,500 square feet. However, this cost won't include all that comes with a professional installation, like wall repair, prep, substrate, full installation, etc.


What Factors Affect Fiber Cement Siding Replacement Costs? 

Even though it's a more expensive siding type, many factors will increase or decrease the overall cost of your project, like square footage, added customizations and more.


1. Square Footage Of Your Project

The total size of your project is the first factor that will affect the cost of a siding replacement project.


Think about it. Replacing 500 square feet is less than replacing 5,000 square feet of siding, right?


When calculating the amount of square footage of siding you want replaced, you must consider other areas you may replace, like soffit, fascia and other trims.


Knowing the average cost per square foot of your project is the first step to accurately calculating its overall cost. By understanding better how much your project will cost, you will have realistic expectations for the size and price.

2. Condition Of Your Current Siding

If your current siding is in great condition, it may be used as the substrate for your new fiber cement siding. A substrate is necessary to add a layer of protection to your walls and help the fiber cement siding last on your exterior better.


If your current siding is not in good condition or is not the proper material for a substrate, then having a new substrate installed underneath the fiber cement siding will increase the cost.


3. Added Customizations

Just as with any home remodeling project, customizations you make to your new product will increase the cost.


For replacement siding, customizations can include board size, profile, shape, texture and color. So, if you want to make yours as personalized as possible, be sure to include room in your budget for the added price tag of customizations.


4. Recommended Additions For Your Replacement Project

If you’re interested in replacing the material yourself, you, of course, can replace the siding and it will cost less. But most professional siding contractors recommend also replacing the soffit and fascia boards — they most likely are due for a replacement as well.


While including these additions in your siding replacement project is not required and will increase the overall cost, they are highly encouraged.
