James Hardie Logo

We Proudly & Exclusively Offer James Hardie Siding & Exterior Products


JamesHardie® siding products are designed to withstand the harshest climates, damage from precipitation, minor impact, and winds up to 130 miles per hour. We carry fireproof fiber cement siding that will not melt when exposed to a heat source.


Your JamesHardie® siding will remain intact despite harsh weather conditions. They won’t warp, rot, or shrink, and are invulnerable to pests like termites and carpenter ants.


JamesHardie® can help save you an average of $5,000 over 15 years with its long paint cycle. It integrates ColorPlus® Technology for a beautiful, baked-on finish that can last up to two times longer than field-applied paint.


Enjoy the attractive, low-maintenance finish that comes with the baked-on color of JamesHardie® siding. Our fiber cement material features the look and feel of natural wood and is available in various design styles and profiles.


All of our products come with a 30-year limited transferable product warranty, as well as a 15-year finish warranty that covers both paint and labor.
