Expert James Hardie® Siding Installation

Installed costs typically range from $12 to $18 per square foot. For a typical 2,000-square-foot home, this translates to approximately $24,000 to $35,000. Contractors who use premium installation components, such as Type #316 stainless steel siding nails will generally fall at the higher end of this range due to superior material quality and long-term performance. 

The top failures are improper nailing (over-driving or under-driving nails), lack of proper expansion gaps (minimum 1/8 inch), and failing to maintain the 6-inch ground clearance. These are all caused by improper installation.

ColorPlus® finishes are warrantied for 15 years. If you use the "Primed for Paint" boards, you will likely need to repaint every 10–15 years, which is still double the lifespan of paint on natural wood.  

It is non-combustible and has a Class A fire rating. It will not ignite when exposed to a direct flame or contribute fuel to a fire.

While James Hardie® siding typically costs more than vinyl, it offers a higher return on investment—often 70–80%—with Class A fire resistance and a 50+ year service life versus 20–30 years for vinyl. Its refined appearance also makes it a preferred choice for higher-end homes. A technical comparison of James Hardie®, wood, and vinyl siding is available for further evaluation.
