Here we get to work and answer the questions our community + clients ask us most!

How does James Hardie siding hold up here in Westchester?

Really, well! We live in HARDIEZONE 5!

Our region has extreme seasonal temperature variations and year-round precipitation. James Hardie HZ5 products are formulated with the highest quality raw materials and proprietary additives to reduce moisture intrusion. This helps prevent your siding from growing mold, shrinking, swelling and cracking.

Siding is exposed to Mother Nature all day, every day, for years. Weather, water, time, fire and pests—all can lead to trouble. That’s why James Hardie’s hardworking products are engineered to stand up beautifully, whatever the elements.

How does James Hardie siding do over the course of time?

One thing’s for sure: As the years go on, we all show signs of aging. But since James Hardie products are created to stand up to the demands of your specific climate, they will look great for years, potentially saving you time and money.

With James Hardie’s added benefit of ColorPlus® Technology—a baked-on color option that resists fading—your siding will look great without excessive maintenance.

Is James Hardie siding made of stone? Is it a masonry product?

The Uniform Building Code defines masonry as a form of construction composed of stone, brick, concrete, gypsum, tile, glass block or other materials laid up unit by unit and set in mortar.

Although James Hardie products are installed with nails, like most masonry materials, they are primarily cemented with performance characteristics similar to brick, stucco and stone. These characteristics include fire, moisture and insect resistance. Many cities include fiber-cement in their masonry definitions for these very reasons.

Can I receive a discount on home insurance for using JH products?

Because JH products are non-combustible, many insurance companies offer a discount. We recommend sharing the information on this page with your insurance company if they are not familiar with fiber-cement siding’s fire-resistance.

How do you clean Fiber Cement Siding and Trim?

Follow these recommendations to clean the exterior of your home and to help maintain the beauty and value of your James Hardie siding.

  • Wash down the exterior surfaces every 6 to 12 months with a garden hose to remove dirt and debris, gently clean your siding with a soft brush or wet soft cloth in a side to side motion in the direction of the plank siding.

    NOTE: Clean by working small sections at a time, starting from the top down to prevent dripping or streaking onto the cleaned area.
  • A low-pressure water spray* and a soft medium bristle (non-metal) siding cleaning brush is most suitable for cleaning fiber cement products.
    NOTE: Acid and high pressure washing can damage the fiber cement surface and is not recommended.
  • Clean James Hardie ColorPlus® products by using water and a soft brush or cloth. For stubborn dirt or stains, a mild detergent and a soft brush may be used.
    NOTE: For paint applied in the field, refer to the paint manufacturer for washing and maintenance requirements.
