For fiber cement, the ColorPlus finish warranty is the part of a James Hardie siding warranty that addresses color and fading, while for vinyl, Exterior Portfolio backs fade through its Chromatix Double Lifetime Warranty. Woman-owned and family-run since 2011, Coastal Windows & Exteriors has completed 7,000+ installations across 730+ towns in Massachusetts, New Hampshire and Maine. The Hardie warranty splits in two: a 30-year non-prorated substrate warranty covers the board, and a 15-year finish warranty covers the color.

What Homeowners Need to Know About Fade Coverage

Two parts: A Hardie siding warranty separates board coverage from finish coverage under different terms.
Board term: James Hardie does not prorate its substrate warranty and stands behind the board for 30 years.
Finish term: ColorPlus Technology finishes and HardieTrim boards carry 15-year limited finish warranties.
Fade coverage: The ColorPlus finish warranty covers the finish against peeling, cracking, and chipping. It also addresses color change beyond normal weathering.
Vinyl fade: Exterior Portfolio vinyl warrants fade to as low as 3 Hunter units through Chromatix. Compare siding options before you decide.
Read the terms: Full coverage details, limits, and exclusions live in the manufacturer warranty document.

Hardie substrate	30 years, non-prorated	The fiber cement board and defects	Long-term structural protection
Hardie ColorPlus finish	15 years, limited	Finish against peeling, cracking, chipping, and color change	Baked-on color retention
