The average cost to reside a 1,500 sq.ft. house with Hardie Plank siding is $12,000-18,000. In lower income areas, homeowners pay less to install Hardie Board, around $10,000-14,500 for the same size house.

James Hardie siding is expensive because it’s a brand name siding that boasts exceptional durability and curb appeal. This siding also has a high ROI and can boost your home’s resale value. Most people prefer houses that are sided with James Hardie compared to cheaper siding alternatives. This is another reason why so many homeowners choose to replace their old siding with Hardie Board.

Here we will review in detail how much you will pay to buy and install Hardie siding.

Average Hardie Board siding cost

Hardie siding costs $7 to 13 per square foot installed. This price includes all materials and installation. James Hardie is a fiber cement siding, and is considered a premium quality product among other fiber cement options.

Putting up Hardie Plank on a 2,000 sq.ft. house will cost $14,000-26,000.

Factors like accessibility, location and job complexity can greatly increase or lower your total siding cost.

Moreover, depending on your desired siding board exposure and color, siding material prices will vary significantly. Also, keep in mind that you need to include the cost of trim, be it wood or PVC / AZEK trim board. We will discuss trim prices below.

Lastly, siding removal and disposal will add $1,500-2,500 to the total cost, depending on the size of the house and the type of old siding you have.

Overall, James Hardie siding materials cost $3.75-4.5 per square foot. This includes the cost of the siding boards, stainless steel nails, trim (at least $1 -2 per 1 square foot of the job size), house wrap (underlayment/vapor barrier) and any other materials needed for the install.

When choosing a 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 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 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 Board

Siding cost also varies depending on how the boards are painted. There are two options:

  1. Pre – primed: you can paint Hardie siding any color you want after the installation is complete.
  2. 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 Plank

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.

The cost of painting your house also varies greatly depending on 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.

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

Prices below are for Hardie LIGHT MIST color, and 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.

Hardie siding cost per square foot

As you can see from the two tables above, Hardie plank costs about $1.60 per square foot for pre-primed (unpainted) boards, and $1.90 per square foot for factory painted siding.

Hardie Siding Prices

An average house requires about 22.5 squares of siding boards, which costs $3,600 – $4,275.

This siding cost estimate is based on data from our Siding Calculator (which you can use to estimate your costs of installing Hardie). While there is about 7-10% waste factor on materials, we do not subtract the area of windows, so in the end it all works out to be about equal.

Prices do not include sales tax which can range in US from 0% in NH to 9.45% in Tennessee.

Labor cost to install HardiePlank

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 the overall 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)

Installation considerations

Hardie, as well as similar composite and wood materials are installed over a flat wall surface with 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 local pro who has extensive experience with Hardie.

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 is a quick siding installation video:


Siding trim board costs

Besides the siding itself, we also need to include the following items in our “price quote”. They are:

1) House wrap
2) Trim boards
3) Nails
4) Caulking

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
Total $1,449

Hardie Pros and Cons

Despite cheaper alternatives, Hardie Plank still remains one of the most popular materials among homeowners who are looking for designer looking siding. Here are Hardie’s main advantages:

– Rot and termite resistant
– 100% fire resistant
– Long lasting: you can easily get 25-35 years of service life
– Superior warranty: most Hardie products come with a limited 50 year warranty
– Designer wood grain appearance: masterfully replicates the look of cedar shingles and shakes
– Resists damage from hail and storms
– Multitude of color options: most color options come with a 15 year limited warranty
– Offers a very high ROI – most re-siding projects recoup 78-85% of the initial cost
– Ideal siding for upscale homes
– Green building material

Some disadvantages to consider

Here are some cons to keep in mind when you are researching whether Hardie would work for your house.

– At least 2 – 2.5 times more expensive than vinyl siding
– Difficult to find qualified installers
– Installation is longer and more challenging than other types of siding
– Heavy, weighs about 300 lbs, compared to 60-70 lbs for vinyl. May require additional reinforcement
– High maintenance: needs to be repainted about 12-16 years.

How you can save money on new siding

James Hardie Siding Cost

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 costs 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 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.

However, if you are planning to go the DIY route and install the siding yourself, its a good idea to visit various local building suppliers and compare their siding prices.

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.

    How much is it for labor to install the 6 inch hardie board compared to the 8 inch and 10 inch, on a 3000 square foot house? Should it make a difference on labor price with whatever size I choose?

    1. Leo B Post author


      Labor is almost the same, and most contractors won’t even make any adjustments. However you do you a little bit less material, so probably you can get $25-40 / square off your bill.

      Good luck

  2. Eugene haney

    Could you please give me the total cost of putting Color Plus on my house it would be 4sq. ft of siding 8.85
    witch would equal 275 sq ft. Max 50 pieces of siding I need installed price Thanks

  3. Phillip Shemansky

    This information helped tremendously. If you could refer me to a good supplier please do so.

      I listed suppliers at the end of this guide. You can buy it from big national suppliers or even local lumber yards. I do recommend to avoid Harvey’s because they are 15-20% more expensive that many other suppliers – I have no idea why homeowners and contractors keep paying these crazy premiums for something you can buys elsewhere a lot cheaper!

      On an average house you can save over $1000 by just going with less expensive supplier! 😀

    When you change the siding, there is always work done on the windows, either repairing or replacing the wood or the window itself. How does that work with the replacement of the siding?

    1. Leo B Post author


      Changing a window does not affect Siding work in any way, unless you have new construction windows.

      Repairing the wood around windows is only needed if that wood is rotten. In most cases only the window sill is rotted, and that’s not often.

      If wood is rotted, it’s usually repaired with wood or PVC boards. If the job is vinyl siding then what is also capped with sheet metal.

      If you’re replacing vinyl with Hardie, then you should probably also replace outside window frame with PVC, but that’s not necessary.

      Basically, this is on case-by-case basis and not always. However if this work needs to be done it’s usually extra money per window.

      I hope this helps. If you have other questions don’t hesitate to ask.

      Sincerely, Leo

    I was with you until the calculation of lineal feet required.

    “We will need 50 + 25 x 4 = 300 linear feet ”

    Why x4? I would think it would be x2.

    1. Leo B Post author


      x4 because for hardie siding, contractors usually install trim on top and bottom – neither is necessary, but looks good. Also x4 presumes that your roof is either flat or HIP, meaning your siding/roof line is flat. If roof is Gable, than you need to account for roof angles on top.

      Hardie Siding Trim

      If you want horizontal trim just at the bottom – then it (Width + Length) x 2

      Again – neither top or bottom horizontal trim is necessary. Also some contractors do bottom trim using 2 pieces – 1×6 and 1×3. 1×6 is installed flat to the wall, and 1×3 is installed “almost” perpendicular – it’s cut at an angle on 1 side to give it a little slope down … something like this:

    Thank you for sharing this information. Although I am on the west coast this is excellent to use as a checklist to make certain I have covered all the bases.
    The only improvement I would suggest is a note section to cover other circumstances.

      You can also use Jig-Saw – you will just go through a lot of blades, if you do a lot of cutting, because cement in Hardie planks will dull your blades fast.

      However, cutting outlets with jig-saw is a lot cleaner and safer that using angle grinder with diamond blade.

      Good luck

      1. Wilky101

        There are diamond jigsaw blades, but an oscillating tool (multi-tool)with a diamond blade works even better(its easier to control than a grinder)
