Hardie Plank Siding Cost vs. Vinyl vs. Fiber Cement vs. Wood
Many homeowners and architects prefer houses that are sided with James Hardie compared to cheaper siding alternatives.
This is another reason why so many people choose to replace their old siding with Hardie siding and why its the preferred siding for many upscale new construction homes.
Lets take a closer look at how the cost of Hardie Board siding stacks up against its competitors: vinyl siding, other popular fiber cement siding brands, such as Allura, engineered wood siding, real cedar wood siding, and stucco.
Estimated siding prices include materials and professional installation.
|Material||Cost per sq.ft.||Cost to install 2,000 sq.ft.|
|Hardie Board siding||$7 – 13||$14,000 – 26,000|
|Fiber Cement siding||$4.5 – 9||$9,000 – 18,000|
|Vinyl Siding||$2.5 – 5.5||$5,000 – 11,000|
|Aluminum Siding||$2.75 – 4.5||$5,500 – 9,000|
|Engineered Wood Siding||$6.5 – 11||$13,000 – 22,000|

|Stone Veneer||$15 – 30||$30,000 – 60,000|
Hardie Siding Cost Based On Board Exposure
When choosing James Hardie siding for your house, keep in mind that the cost of materials is based on “exposure”, or how much of each board is visible, and how much is concealed.
Among Hardie Plank lap siding options, there is clap board exposure that is 4″, 5″ 6″ and 7″ inches wide. This means that each row is 4-7″ inches apart vertically. The most popular exposures are 4″ and 5″. 6″ and 7″ exposure boards are considered “premium” and cost more.
The bigger exposure you have, the lower is your siding cost per square foot. The difference comes from the fact that each board has a 1.25″ nailing strip, so the wider the exposure, the less siding material you actually use (percentage wise).
At the same time, contractors usually charge MORE for wider exposure siding, because it’s considered “premium”.
This makes no sense at all, so if you plan to have Hardie siding installed on your house, you should negotiate with your installer to avoid paying a premium price for wider exposure.
Hardie Board Siding Dimensions
The planks come in 12 foot length, and to accommodate for different exposures, each board can be different width. See the table below:
|Board Size (width)||Board Exposure||Board Length||Pisces / Square (100 sq. ft.)|
|5.25″||4″||12 feet||25 pcs.|
|6.25″||5″||12 feet||20 pcs.|
|7.25″||6″||12 feet||17 pcs.|
|8.25″||7″||12 feet||14 pcs.|
Cost of Unpainted vs Factory Painted Hardie Plank Siding
Its important to note that the total cost of Hardie siding varies depending on how the boards are painted.
There are two options:
- Pre – primed: you can paint Hardie siding any color you want after the installation is complete.
- Factory – painted (initially more expensive): you pre-order the siding color you want. There are 24 stock colors to choose from. There are pros and cons to both pre-primed and factory painted Hardie Plank lap siding. We will discuss these separately, as there is no clear answer to which is better.
Cost of Pre-primed (unpainted) Hardie Siding
See costs in your area Start Here - Enter Your Zip Code
Note that these prices are for pre-primed (unpainted) boards, so you also need to account for hiring a painter to give your siding a finished look.
On average, you can expect to pay $1.5-2.75 per square foot to paint your fiber cement siding. So if your house has 1,800 sq. ft of siding, you will spend $2,700-4,950
Keep in mind that the cost of painting your house will vary greatly depending on local labor rates for painting pros, who you hire for the job, and what type of paint you use. For example, ceramic paint costs much more than regular exterior paint, but will last much longer.
James Hardie recommends painting its siding boards with 100% acrylic exterior paint, such as the Benjamin Moore Exterior SuperSpec.
|Board Exposure||Cost per 12′ Board||Cost / Square (100 sq. ft.)|
|4″ exposure||$6.62||$165 / square|
|5″ exposure||$7.98||$159.60 / square|
|6″ exposure||$9.24||$157.08 / square|
|7″ exposure||$10.51||$147.14 / square|
Cost of Painted Hardie Plank Siding
See the table below for Hardie Siding cost in a LIGHT MIST color. Note, that pricing may be different for other colors.
Because there is a total of 24 stock colors it would take forever to create a complete database of Hardie prices for all colors.
Basically your cost may differ by 5-6% up or down, depending on the color and supplier.
|Board Exposure||Cost per 12′ Board||Cost / Square (100 sq. ft.)|
|4″ exposure||$8.11||$202.75 / square|
|5″ exposure||$9.64||$192.80 / square|
|6″ exposure||$11.20||$190.40 / square|
|7″ exposure||$13.27||$185.78 / square|
We are once again looking at the same pricing pattern – the wider the exposure, the less materials cost.
Labor Cost To Install James Hardie Siding
When it comes to the cost of siding installation most pros charge 2 to 3 times the cost of materials for a particular job. Thus, a quote from a siding pro includes all materials, labor, overhead and profit in one final price.
So in our example of a 22.5 square job (2,250 sq.ft house) the materials cost $9,000 (2,250 x $4 per square foot).
Given this figure, a siding pro will quote you the total installation price between $18,000 – 27,000.
Keep in mind that your location can have a big impact on labor charges. Depending on where you live, local siding installers will have various labor rates. High income areas such as big cities in the Northeast and California will have the highest contractor fees.
On the other hand, Southern states have some of the lowest labor rates in the country. The difference in the final siding installation cost can vary by as much as 20% depending on your location.
Moreover, often contractors charge more to install premium brand name siding, such as James Hardie. This premium can be 5-10%
Other factors that may increase your overall siding installation cost are:
– Number of windows and doors (installing siding around them requires extra work)
– Configuration of the house (if your home has many gables, corners, or irregular shapes, this will increase the price)
– Number of stories (second/third floor siding installations are more time consuming and complex, and will incur extra charges)
– Overall complexity of the job
– Size of your house (the bigger the job the more it will cost. keep in mind that very small jobs under less than 1500 sq.ft. may actually incur a premium charge because the contractor has to spend time setting up and cleaning in the same as as for a bigger job)
– Additional reinforcement of the house structure to accommodate the heavy weight of Hardie Board siding.
Cost of Hardie Siding Trim Board
Besides the siding itself, we also need to include the following items in our “price quote”. They are:
1) House wrap
2) Trim boards
The most expensive item on this list is the siding trim board, if you go for quality products such as AZEK / PVC. While this trim material costs more, it is the most durable and longest lasting option.
I do not recommend using primed / pressure treated wood trim, as it will rot in just few short years and you will be repairing / replacing sections all around your house.
Vinyl siding trim is also not as durable and good looking, but costs a lot less than PVC, so if you are trying to save money, it can be a good option.
PVC trim boards should be 6×1 on all corners, at the bottom, top, and around doors. You can use less expensive 4×1 trim boards around windows.
Estimate how much siding trim you need
In our 22.5 square house we assume to have:
2 entrance doors
20 total windows
1 garage door
4 outside corners
In our hypothetical example the house has 18 feet of vertical wall to receive siding, and the ground dimensions are 50 x 25 which equals to 22.5 squares of exterior wall.
We will need 50 + 25 x 4 = 300 linear feet of horizontal 1×6 trim.
For corners we will need 18′ x 8 (2 boards for each corner) = 144 feet of 1×6 board.
For doors we will need 18 ln. ft. each door – 36 feet total.
For windows we will need about 15 feet of 1×4 trim board. 20 widows total x 15 feet each = 300 feet of board.
But the devil is in details!
To minimize waste we want to use appropriate size board. For example, PVC trim comes in 12, 16 and 18 feet lengths. So for doors we can use 18 boards and have almost no waste.
For windows we should use 16 foot boards (assuming each window is about 5 x 2.5′). So we will need twenty 16′ boards to trim all windows.
On vertical corners we can, in most cases, get away using 18′ boards and we will need 8 of these.
On horizontal runs, we can butt-join different lengths, so waste is not so much a factor.
Trim materials list
1×6″ Trim: We will need a total of 17 boards for horizontal runs + 8 boards for vertical runs + 2 boards for doors = 27 boards.
1×4″ Trim: As mentioned above, we will need one 16′ board per 5×2.5′ window. If there are 20 windows, we will need 20 pcs. of 1×4 board.
Cost of AZEK vs PVC trim board
First of all let me mention that AZEK will be a little more expensive than store brand PVC trim.
What you should look for is board density. If both the store brand and AZEK have similar density, go for the cheaper option.
But, in Home Depot they sell a line of really light PVC board (it is porous and has a lot of air inside), so in this case, go for AZEK, or another more dense option.
PVC trim board prices at Harvey BP Supply
|Harvey 1×6 PVC Trim Board – 18′ long||Harvey 1×4 PVC Trim Board – 18′ long|
|$37.63 each||$21.67 each|
So for our example, the cost of PVC trim will be:
1×6 board 27 * $37.63 = $1,016.01
1×4 board 20 * $21.67 = $433.40
Hardie Siding Installation Considerations
James Hardie siding, as well as similar composite and wood siding materials are installed over a flat wall surface.
There is also a house wrap / moisture barrier installed between siding and house exterior walls.
Before siding is nailed on, all trim must be installed on corners, around windows and doors, and optionally at the bottom and under the roof line.
Pro Tip: if you plan to install James Hardie or other types of fiber cement siding, its best to install a weather resistant barrier under the siding.
This barrier will ensure that moisture will not penetrate under the siding, causing rot and mold.
Installing a weather resistant barrier is particularly important if you live in states that have high humidity throughout the year and a lot of rains on a regular basis.
Moreover, if your want the installation to be done correctly, its best to hire a siding pro who has extensive experience with Hardie siding.
Every siding material has different installation specs and nuances that a contractor needs to know and follow.
Moreover, even different brands in the same siding category will have certain variations in how they are installed.

Here are some cons to keep in mind when you are researching whether Hardie siding would work for your house.
– At least 2 – 2.5 times more expensive than quality vinyl siding
– Difficult to find qualified installers
– Installation is longer and more challenging than other types of siding
– Heavy weight. Hardie siding boards typically weigh about 300 lbs, compared to 60-70 lbs for vinyl siding. This extra weight may mean that your house structure will require additional reinforcement. This can add an additional 10-15% to the total siding replacement cost.
– High maintenance: needs to be repainted about 12-16 years.
Hardie Board vs Hardie Plank Siding
James Hardie is a cement board siding, that is made of a mixture of wood pulp, sand, cellulose fibers, cement and other organic materials, which are molded to replicate the authentic look of wood siding.
As such, fiber cement siding is extremely durable, low maintenance, impervious to insects, rot and fire damage.
Essentially, it offers homeowners the look and feel of real wood (or close enough to it), without the high cost and the hassle of taking care of real wood siding.
Did you know? The terms Hardie Board and Hardie Plank siding are used interchangeably and mean the same thing.
Moreover, many people make the mistake of equating Hardie Board siding with fiber cement siding.
However, this is not the case. There are a number of different cement board siding manufacturers and James Hardie happens to be the most famous one.
James Hardie makes exclusively fiber cement siding and has a number of product lines:
1. HardiePlank (board) siding – this is a lap siding that comes in 6 different product options
2. HardiePanel siding – this is a vertical siding that comes in 4 different product options
3. HardieShingle siding – this is a shingle siding that comes in 4 product options
How You Can Save Money On James Hardie Siding
If you find that James Hardie is very expensive – the fact is, it is expensive because it’s a well established brand and is often a de-facto product for architects and builders!
There are other composite siding materials, such as LP SmartSide, that cost as much as 25% less than Hardie. They are not as well known, and need to keep prices down, to penetrate the market.
However, these materials are very similar in quality (if not better in some cases), and are worth considering!
Where To Get Hardie Siding Price Quotes
If you are planning to hire a pro to install new siding, you should get 3-4 free quotes from local siding pros.
IF you want to see whether or not you are getting a fair price quote, or if you are considering doing the install yourself, you can visit local siding suppliers in your area.
I get most of my material quotes from local suppliers in the Boston, MA area. Closest to me is Harvey BP in Waltham, MA. Harvey is actually more of an expensive materials supplier AND their stores are mainly in the North East US (Massachusetts, Connecticut, Rhode Island, New Hampshire and New York).
You can try ABC supply, Beacon supply, Alside supply, as well as smaller lumber yards and local suppliers of building materials, roofing and siding.
