Hardie plank siding lasts decades when seasoned Hardie plank siding contractors install the board. With 7,000+ installations completed since 2011, Coastal Windows & Exteriors holds James Hardie Elite Preferred status, stands as the only woman-owned James Hardie President’s Club winner in New England, and serves 730+ towns across Massachusetts, New Hampshire and Maine. Our crews install every board, barrier and trim piece to manufacturer specs so your siding reaches its full lifespan.
What Actually Determines Fiber Cement Lifespan
- Warranty term sets the floor: James Hardie backs the board with a 30-year nonprorated limited warranty. Coverage holds at full strength through the entire term rather than sliding downward.
- Moisture management matters most: Hardie Weather Barrier keeps water out and lets vapor escape. A dry wall cavity adds years to any cladding system.
- Pests never factor in: Carpenter ants and termites have no interest in cement fibers and sand. Wood siding cannot make that claim.
- Freeze-thaw resistance: Fiber cement holds dimension through repeated freezing and thawing. Vinyl grows brittle in deep cold and warps in summer heat.
- UV and finish endurance: ColorPlus Technology resists fading for 15 years under warranty. Field-applied paint on wood needs redoing every three to five years.
- Rinse twice a year: A garden hose and a soft brush handle routine cleaning. That small habit protects the finish for decades.
- Installation quality decides the rest: Even the best board underperforms behind careless work. Elite Preferred crews follow manufacturer specs at every step.
Choosing for Maximum Lifespan
- Top Recommendation: HardiePlank lap with ColorPlus Technology installed by an Elite Preferred crew for full warranty protection.
- Best for Coastal Exposure: HardieShingle for the cedar look minus the rot, curling and splitting.
- Best for Modern Builds: Hardie Panel vertical siding with Trim batten boards for clean lines that hold up.
