Hardy plank is an alternative siding material that has advantages over wood and vinyl siding. Due to its makeup of cement-based elements, it provides outstanding durability that traditional siding materials cannot match. Plank trim kits accompany siding purchases and these can easily be customized with a little know-how using the right tools. Taking some time to examine the process for customizing the trim will lead to a successful project.


Step 1: Type Board and Measurements

Decide which boards are window and door trim placements along with fascia, soffit and corner boards. Determine measurements for all to make the needed cuts.

Step 2: Cut the Boards

Mark all measurements to follow with the circular saw and then make all necessary cuts to the trim pieces for one elevation.

Step 3: Attach the Trim

Attach the cut trim pieces in place using stainless steel nails. Use a level to check the accuracy of your work making sure each attachment is as straight as possible. Repeat the steps for every elevation of the building.

Step 4: Touch Up

Using the paint provided with the trim boards, touch up all nail holes matching the trim color to that of the rest of the structure.

Remember a few helpful hints:

  1. Always locate attachment nails at least a ½ inch from the trim board edge so you can avoid any chance for chipping, splitting or weakening the plank. Make sure to attach a minimum of 2 and a maximum of 6 finishing nails at least every 16 inches.
  2. Due to the cement and silica content of a Hardy Plank, make sure to always use a ventilator mask and protective eyewear when cutting because the saw will throw off considerable dust you do not want to inhale. This is not a suggestion.


Home construction, along with do-it-yourself home remodeling, has helped popularize Hardy Plank siding in markets all across the world. Due to its cement-based constitution, Hardy Plank siding has gained fast popularity and widespread use due to its unmatched durability as a viable alternative to either traditional wood or vinyl siding.

The name “hardy plank siding” is a combination play on both the product’s reputation for unequaled ability and strength and because the inventor of this wondrous material happens to be named James Hardie. He developed his “Hardie” plank siding as a competitive alternate choice for vinyl and wood usage in the Australian home construction and remodeling markets. Word spread quickly and soon he was marketing throughout the worldwide home siding industry.

The planking visually imitates a wood look while providing extreme durability making it a popular choice in extreme climates.
