Coastal Windows & Exteriors is a James Hardie Elite Preferred contractor and a woman-owned James Hardie President’s Club winner, serving 730+ towns across Massachusetts, New Hampshire and Maine, with 7,000+ installations completed since 2011. Most reported problems with James Hardie fiber cement siding trace back to installation, not to the boards themselves.
Issues Worth Knowing About
- Installation Drives Outcomes — Fiber cement rewards crews who follow manufacturer specifications and punishes those who improvise. Elite Preferred certification exists to close that gap.
- Sealant Ages Before Boards Do — Caulk at trim joints and transitions wears out ahead of the cladding. Refreshing sealant is routine upkeep, not a product defect.
- Moisture Behind the Wall — Any cladding fails if water gets behind it and stays. Hardie Weather Barrier plus correct flashing keeps the wall cavity dry.
- Weight Requires Skilled Hands — Fiber cement runs heavier than vinyl, which makes handling and fastening a trained-crew job. DIY attempts drive a large share of complaints.
- Old Sheathing Hides Trouble — Rot under existing siding shows up during tear-off, not before. Our team inspects sheathing on every job and reports what we find.
- Cut Debris Needs Control — Cutting fiber cement generates dust, so crews use dust-reducing methods on site. Lead-Safe EPA certification shapes how we handle older homes.
- Repairs Stay Straightforward — Damaged boards swap out one at a time. A targeted board-level repair beats replacing a full elevation.
How to Sidestep the Most Common Issues
Top Recommendation: Certified Elite Preferred installation, which prevents the moisture and fastening issues behind most complaints.
Best for Peace of Mind: Full tear-off with sheathing inspection, so hidden rot gets found and fixed.
Best for Existing Siding: Board-level repair on damaged sections rather than a whole-wall tear-out.
