What is the James Hardie Siding Warranty?

Home with new siding and an American flag

The moment your siding is first installed on your Chicagoland home, it begins enduring bright sunlight, harsh winds, snow, hail, and rain. How can you protect your new investment? A great warranty you can trust is crucial to keeping your home and your money safe. Plus, an exceptional warranty shows just how confident the manufacturer is in the product. Bad warranty? Bad product.

That’s why Bak Brothers offers siding and workmanship warranties you can trust. We’re confident in our products and our team. The James Hardie siding warranty protects your purchase, and our workmanship warranty ensures your investment in a smooth installation process is well worth it.


At Bak Brothers, we’re proud to offer a 20-year workmanship warranty to our Chicagoland customers. You can enjoy peace of mind knowing that your siding installation is fully protected. It’s just one more way you can feel good about your purchase with our family-owned company.


At Bak Brothers, we sell James Hardie siding, which comes with its own warranty. Effective from September 2018, our James Hardie siding is protected by the HZ5 warranty.

Below is the James Hardie HZ5 promise.

What Is The HZ5 James Hardie Warranty?

James Hardie’s engineers divide their siding into two types, called HZ10 and HZ5. “HZ” stands for HardieZone. Each HardieZone represents the types of weather in different parts of the country. In Chicagoland, we’re in HardieZone 5.

HZ5 siding, or HardieZone 5 siding, is made to endure our extreme weather. We endure ice, snow, and extreme cold every year. The James Hardie warranty comprehensively covers the extreme weather we face here in Chicago.

What’s In The HZ5 Warranty?

A 30-year limited warranty from the date of purchase on Hardie Fiber-Cement products, including:

  • HARDIESOFFIT® HZ5® products

The James Hardie products are guaranteed to resist damage from hail and termite attacks. The James Hardie products will also be free from defects in material and workmanship. During the 30-year limited warranty period, James Hardie will replace (at their discretion) defective parts of the siding product OR reimburse the covered person for up to twice the original retail cost of the defective portion of the James Hardie product.

To receive, replacement, or reimbursement, the covered person must give James Hardie written notice of the defect. You’ll have to prove that you are the covered person, share photos of the claimed defect, and explain the location and details of the defect. Then, James Hardie will investigate your claim.

What Not In The HZ5 Warranty?

  • Failures in installation (we’ve explained below why it’s so important to have certified experts installing your siding!)
  • Any damage after shipping from James Hardie
  • Damage from incorrect design of the structure
  • Water infiltration or mold
  • Extreme weather, including tornados, hurricanes, floods, earthquakes, severe weather, or other natural phenomena
  • Paint or stains from a third party

Why A Contractor Should Install Your James Hardie Siding

James Hardie provides an exceptional product, and their warranty reflects that. The HZ5 warranty covers any damage to your siding on the manufacturer’s side. That’s a vote of confidence in James Hardie’s engineering, performance, and product strength.

Be forewarned: the warranty does not cover any damage that occurs when the siding is being installed. That means if you damage your siding while attempting to install it yourself, you can’t get back the cost of the damage from James Hardie. If you hire a sloppy contractor untrained in best practices, you won’t be reimbursed for any damage to your product.

That’s why it’s crucial to have a trustworthy contractor trained in James Hardie’s best practices handling your remodel.

At Bak Brothers, our team is specially trained in the proper installation of James Hardie products, directly from the manufacturer. That way, if there’s any damage or defect in your product from James Hardie’s end, you can take full advantage of their warranty and recoup the cost.

Everybody wants their product installed well. That’s just common sense! But when you’re investing this much time and money into a massive project, trusting the workmanship of your installer is critical.
