Vinyl Siding Prices : Calculators & Estimators : Hardie Siding Calculator
Hardie Plank Siding Estimator
Our Hardie siding calculator can help you price out your next cladding project by calculating the approximate cost of Hardie Plank (also frequently called Hardie Board). Generally, these fiber cement boards are quite a bit more than the cost of vinyl siding.
Specifically, Hardie Plank is a more expensive product that also carries higher installation costs. So, one square (100 ft or 10 feet by 10 feet) of James Hardie siding will run approximately $2,500, while vinyl siding might run roughly $1000. Scroll down to read more on our analysis, as well as to play around with our James Hardie siding calculator.

Hardie Siding Calculator First Steps
1. Typically, the existing siding must be removed - not always, but in two thirds of projects. This step is called a tear off and runs approximately $1 per square foot. However, some companies charge as much as $1.50 per square foot. For our purposes, we calculate the tear off to run $1 per square foot.
2. The next step is to apply OSB or oriented strand board to the exterior (basically cheap plywood boards). This substrate provides the proper structure that is insures that the Hardie Board lasts a long time. This step runs approximately $4 per square foot. However, some companies charge as much as $5 per square foot. For our purposes, we calculate the OSB to run $4 per square foot.
3. Add a layer of weather barrier, which helps prevents water and any moisture from getting inside the walls. This protective layer is important to safeguard the integrity of the home over the next two to three decades. For our purposes, we calculate the weather barrier to run $1 per square foot.
4. Hardie Board or fiber cement boards are obviously a big part of the total project cost. The boards run approximately $7 to $9 per square foot, which includes the labor cost. Our Hardie siding calculator adds $8 per square foo for both the cost of the boards and the labor to install said boards.
5. The next step involves whether the boards need to be painted. If they are painted at the factory, we add $1 per square foot. If, however, they are to be painted on site, we will add $2 per square foot.

6. Trim work is an important step to making sure your exterior siding looks super professionally done. This includes all trim, fascia, and soffits. Additionally, this is where hiring a really good siding company is so key. However, quality local companies also charge quite a bit for this detail work. Certainly how intricate or complex the installation will affect whether the contractor can easily get the job done or whether they have to spend more time with the decorative touches and accessories.
The more angles, chimneys, etc your home has, the more expenisve the trim work will be. This step runs approximately $5 per square foot. However, some companies charge as much as $6 per square foot. For our purposes, we calculate the trim work at $5 per square foot.
7. Next on the list involves the part of the country that you live in. More urban locations or states that have high business taxes will result in higher contractor costs due to overhead, worker's comp and labor rates. Our calculator simply adds a multiplier for those locations where consumers should expect to pay more for their James Hardie siding.
7. The second to last question in our Hardie siding calculator is this: what type of company that you intend to hire? The list (from least expensive to most expensive) goes like this: handyman, independent siding installer, siding company, and general contractor.
8. Finally, we ask the amount of siding you have. We self populate 1000 square feet so that it is easily visually to see what you will pay per square foot.
