Protect Your Family from Exposures to Lead


If your home was built before 1978, there is a good chance it has lead-based paint. In 1978, the federal government banned consumer uses of lead-containing paint, but some states banned it even earlier. Lead from paint, including lead-contaminated dust, is one of the most common causes of lead poisoning.


Is your home, your building, or the child care facility or school your children attend being renovated, repaired, or painted?

Why is James Hardie Siding so durable?

Why is James Hardie Siding so durable?

Due to its superior durability and aesthetic appeal, James Hardie siding has become a popular choice among homeowners. James Hardie siding is a solid and reliable building material made of fiber cement that can last for decades in any climate.

Unlike traditional wood or vinyl siding, James Hardie’s fiber-cement boards are made of cement, sand, silica cellulose fibers, and water. These materials provide moisture resistance while also being impact resistant against hail and other elements of nature. Additionally, the unique composition also provides fire protection from most natural sources such as wildfires or cigarette ashes, which is why it has earned the highest class A rating when tested regarding flame spread testing standards according to the ASTM E84 Class A rating system.

Not only does it stand up well under extreme weather conditions, but it also does not rot over time like wood will – this is because the fibers swell when wet rather than rotting away like wood can if exposed to too much moisture over time. This makes James Hardie Siding an extremely durable choice for those who want their home protected during harsh weather while maintaining a beautiful appearance at all times!

What’s more impressive about this siding is that you don’t have to compromise on style either; with various colors, textures, and trim options available, you can customize your house in whatever way suits your tastes without worrying about compromising on quality or longevity! All in all, there’s no denying that James Hardie Siding offers one of the best solutions for homeowners wanting maximum durability and unparalleled elegance!
