Say Goodbye to Pecked Siding, Meet the Impeckable™ House by James Hardie

Hardie^® fiber cement siding helps protect your home from woodpecker damage

CHICAGO, Sept. 2, 2025 /PRNewswire/ -- James Hardie Building Products Inc. (James Hardie), a subsidiary of James Hardie Industries plc (NYSE: JHX; ASX: JHX) and the North American leader in fiber cement home siding and exterior design solutions, introduces The Impeckable™ House—a house that can take on a whole forest of woodpeckers.

Over the course of time, traditional wood siding on homes has always been a huge target for woodpeckers to damage, meaning homeowners have long seen them as pests. The United States' 23 unique species of woodpeckers add up to an estimated population of over 70 million woodpeckers in North America and in Wisconsin alone, there are an estimated 1.4 million woodpeckers*. To help homeowners outsmart their toughest pests, James Hardie built The Impeckable™ House, which was designed to prove how wood-look homes and woodpeckers can live in harmony. Placed in a dense, woodpecker-rich forest in Wisconsin, the house and its siding faced the ultimate challenge.

The Impeckable™ House was built with Hardie^® Plank siding and trim products. Hardie^® fiber cement siding, pioneered by James Hardie, the #1 brand of siding in North America**, provides an authentic wood-look style with the added durability of Hardie^® fiber cement for long-lasting beauty.

After several months, The Impeckable™ House remains undamaged, despite residing in a woodpecker-filled forest during peak mating season when they are most active. The house will be donated to Gensburg-Markham Prairie, part of the larger Indian Boundary Prairies managed by Northeastern Illinois University and The Nature Conservancy in Illinois, where it will remain a haven for those who study woodpeckers.

"Homeowners shouldn't have to choose between beauty and durability," said Sean Gadd, president of North America for James Hardie Building Products Inc. "The Impeckable™ House proves that with Hardie^® products, you can create a beautiful home that's meant to last and holds less appeal to pests like woodpeckers."

In addition to helping to resist damage from pests like woodpeckers, Hardie^® fiber cement siding products are noncombustible*** and resist damage from moisture, meaning the siding won't swell, crack, or warp due to rain, sleet or snow. All Hardie^® siding products are Engineered for Climate^® to provide optimal performance specific to the region where they're used. With a wide range of colors and styles, Hardie^® siding and trim products are an ideal, low-maintenance solution for a wide range of climates and home styles.

***Hardie® fiber cement products are noncombustible and/or have a Class A fire rating when tested in accordance with ASTM E84. Fiber cement fire resistance does not extend to applied paints or coatings, which may be damaged or char when exposed to flames. The use of noncombustible siding, combined with other fire mitigation measures, may help harden a home against external fire.
