Most common problems with Hardie plank siding trace back to installation, and certified Hardie plank siding contractors prevent the handful of issues homeowners report. Serving 730+ towns across Massachusetts, New Hampshire and Maine, Coastal Windows & Exteriors is the only woman-owned James Hardie President’s Club winner in New England and a James Hardie Elite Preferred contractor with 7,000+ installations completed since 2011. That track record means every board, fastener and flashing detail on your home goes up the way the manufacturer intended.
Where Problems Start and How Crews Stop Them
- Improper fastening: Nails driven too deep or too shallow create movement at the seams. A certified crew follows manufacturer nailing patterns so each plank sits flat and stays put.
- Skipped weather barrier: Fiber cement performs best over a proper moisture layer. Hardie Weather Barrier blocks water intrusion and keeps the wall cavity drying out from the inside.
- Cut-edge neglect: Field cuts need sealing so the raw edge never drinks moisture. Sloppy finishing shows up years later as swelling near trim and corners.
- Painting over ColorPlus: Some crews field-paint what arrived factory-finished. That choice trades a 15-year finish warranty for a coat that fades far sooner.
- Poor flashing at openings: Windows and doors need flashing that sheds water outward. Weak detailing here causes leaks that get blamed on the siding itself.
- Non-certified labor: Anyone may buy the product but few hold Elite Preferred standing. Certification protects your warranty and gives you a real place to turn.
- Wrong expectations on maintenance: Fiber cement wants a garden-hose rinse twice a year. Owners who skip that see grime build where gutters overflow.
Your Best Path Around Hardie Problems
- Top Recommendation: Hire an Elite Preferred crew so manufacturer specs guide every fastener and every flashing detail.
- Best for Older Homes: Full tear-off with sheathing inspection so hidden rot gets fixed before new board goes up.
- Best for Peace of Mind: Factory-finished ColorPlus paired with certified installation for warranty coverage on board and color alike.
