The James Hardie siding warranty is one of the best in the business. It gives you peace of mind that you have a quality product from a professional company. But warranties can be tricky, so let’s consider what you need to know about the Hardie warranty.

James Hardie Siding Warranty: The Basics

James Hardie offers a 30-year, non-prorated limited warranty. A non-prorated warranty covers the full cost of replacement or repair of a product during the specified warranty period without considering any depreciation or reduction in value over time.

Essentially, if your siding experiences issues covered by the warranty, James Hardie will replace or repair the defective portion or reimburse you up to twice the product’s original retail price. The warranties ensure the products are free from manufacturing defects and resist damage from hail and termites.
