James Hardie siding carries a 30-year nonprorated warranty on the material, plus a separate 15-year warranty covering the ColorPlus Technology finish against fading, chipping and peeling. Coastal Windows & Exteriors, a woman-owned James Hardie Elite Preferred contractor, has completed 7,000+ installations since 2011 across 730+ towns in Massachusetts, New Hampshire and Maine. Its fiber cement specialists register every project, so your coverage is documented from the day the boards go up.
What the Manufacturer Covers
- Thirty years, nonprorated: Coverage on the siding material holds its full value across the entire term rather than shrinking a little each year the way many warranties do.
- Fifteen years on the finish: ColorPlus Technology carries separate protection against fading, chipping and peeling, keeping your chosen shade looking deliberate for a long stretch.
- Color baked in, not sprayed on: Pigment goes through multiple layers during manufacturing, which is why the finish resists wear that field-applied paint cannot match.
- Rot and pest exclusions vanish: Fiber cement gives termites and carpenter ants nothing to eat, removing two failure modes that shorten the life of wood cladding.
- Registration matters: Keep your paperwork and product details on file, since claims move faster when the install date and materials are documented.
- Installation affects standing: Coverage assumes the boards went on per specification, another reason certification separates a bargain crew from a certified one.
- Compare before you buy: Wood cladding and vinyl siding products seldom offer nonprorated terms of this length, a gap worth weighing during any siding replacement project.
Reading Warranty Terms Before You Sign
Top Recommendation: Confirm both the 30-year nonprorated material warranty and the 15-year ColorPlus finish coverage in writing.
Best for Peace of Mind: Certified installation paired with a documented product packet kept on file.
Best for Value Seekers: Fiber cement over lower-cost cladding that offers shorter, prorated terms.
