Coastal Windows & Exteriors is a woman-owned James Hardie Elite Preferred siding contractor and President’s Club winner, serving 730+ towns across Massachusetts, New Hampshire and Maine with 7,000+ installations completed since 2011. James Hardie siding installers pair a 30-year nonprorated product warranty with their own workmanship coverage.
How Warranty Coverage Stacks Up on Your Home
- Thirty-Year Nonprorated Coverage — Nonprorated means coverage holds full value across the whole term. A claim in year 28 carries the same weight as year three.
- Fifteen-Year ColorPlus Protection — Your ColorPlus Technology finish carries separate coverage against fading, chipping, and peeling. That protection runs 15 years from installation day.
- Certification Protects the Paperwork — Manufacturer warranties assume correct work at every step. Hiring certified James Hardie siding contractors keeps your coverage intact.
- Workmanship Coverage Sits Alongside — Product warranties address the board itself. Installer workmanship coverage addresses how that board went onto your wall.
- Transferable Value at Resale — Remaining coverage travels with the home to its next owner. Buyers notice, which supports that 144.9% return figure.
- Documentation You Keep — We hand over warranty registration details at project close. Nothing depends on tracking down a crew years down the road.
- One Point of Contact — Should a question arise, our office fields the call. You never get bounced between a hotline and a subcontractor.
Choosing the Coverage That Fits Your Plans
- Top Recommendation: Pair the 30-year nonprorated product warranty with a certified installer’s workmanship coverage.
- Best for Long-Term Owners: Fiber cement with ColorPlus, since 15 years of finish coverage removes repainting from the budget.
- Best for Sellers: Transferable warranty documentation, which strengthens buyer confidence and supports the 144.9% ROI figure.
