The Hardie board warranty helps keep your siding safe. It covers common problems like cracks, rot, and damage from bad weather. The warranty is strong, but it only works if the siding is put on the right way. It also needs to be cared for over time. If that does not happen, the warranty can be lost.
It is helpful to know what the warranty covers and what it does not. Some problems are included, but others are not part of the plan. Below, we will explain the main points. You will see what is covered, what is not, and how to keep your siding protected for years.
What the 30-Year James Hardie Warranty Covers
James Hardie siding comes with a 30-year, non-prorated warranty on the board itself. That means if there’s a manufacturing defect, Hardie will repair or replace the affected portion of your siding.
Substrate Coverage Explained
This warranty is meant to cover the problems most homeowners actually run into. It protects against cracking or rotting that can show up over time, and it also accounts for the wear that comes from normal freeze and thaw weather. Coverage extends to pest damage too, including termites, which are a common issue with wood and wood-based products. Altogether, the warranty is there to make sure the material holds up and your investment is better protected.
What Hardie Will Do
If a claim is approved, Hardie will either replace the defective siding or refund up to twice the original retail cost of the affected section. Keep in mind that labor for replacement is not included under this warranty.
Transferability
This warranty can be transferred once, usually to the first new owner after you sell your home. That makes it a strong selling point if you ever list your property.
ColorPlus® Finish: The 15-Year Warranty
Hardie’s ColorPlus finish is known for its baked-on durability and fade resistance. Along with the siding warranty, you also get a 15-year finish warranty.
What’s Covered
This warranty protects against peeling, cracking, and chipping. In the first year, Hardie will cover both paint and limited labor. After that, coverage is prorated through year 15.
Fade and Chalk Protection
The finish warranty also covers excessive fading and chalking. This is important for homeowners who want to keep their siding color looking sharp for years.
Repainting Rules
If you ever need to repaint, Hardie requires the use of 100% acrylic paint and proper surface prep. Following those rules keeps your coverage safe.
What Can Void Your Coverage
Many warranty claims are denied because of installation or maintenance mistakes. Here are the most common reasons:
- Improper installation, such as incorrect clearances or fasteners
- Missing or poorly installed flashing and water barriers
- Damage caused by pressure washing
- Structural movement or foundation issues
- Use of third-party paints or sealants
- Salt damage near sidewalks and driveways
- Mold, mildew, or lack of regular cleaning
Key takeaway: Choosing the right contractor and following maintenance steps is just as important as the product itself.
How to Keep Your 30-Year Warranty Intact
Installation Standards
The most important factor is installation. We always install siding according to James Hardie’s official instructions and local code. This includes the right nails, flashing, and clearances. That’s why working with a James Hardie trained contractor makes a difference.
Simple Maintenance Steps
- Wash siding once or twice a year with a garden hose and a soft brush
- Check caulked joints regularly and re-caulk when needed
- Avoid harsh cleaners or pressure washing
- Make sure gutters and downspouts direct water away from siding
Cold-Weather Habits
For Chicago homeowners, remember to keep de-icing salts off the base of your siding. Salt can damage cement-based products if it’s allowed to sit too close for long periods.
Do You Need a Preferred Contractor?
The product warranty is tied to James Hardie, but improper installation can void your coverage. That’s why hiring a trained contractor like us is so important. Along with following Hardie’s guidelines, we also back our work with our own workmanship warranty, giving you added protection.
How to File a Warranty Claim
If you ever need to file a claim, here’s what to do:
- Notify James Hardie in writing within 90 days of noticing a problem
- Gather documents such as proof of purchase, contractor information, and photos
- Protect the area until Hardie has inspected it
- Submit your claim online or by phone through Hardie’s claims department
We often help our customers with this process to make sure nothing is missed.
Local Note: Why HZ5 Matters in Chicagoland
James Hardie makes siding for different weather zones. Each zone is made for the kind of weather in that place.
In Chicago, we are in the HZ5 zone. This siding is built to handle snow, ice, and cold winters. It also works well in hot summers. The boards are made to deal with big changes in temperature.
Using siding made for our zone helps it last longer. It stays strong in storms and does not need as many repairs. For homeowners, that means more protection and less worry about the weather.
