Coastal Windows & Exteriors is a woman-owned, family-run James Hardie Elite Preferred contractor. We serve 730+ towns across Massachusetts, New Hampshire, and Maine, with 7,000+ installations completed since 2011. James Hardie fiber cement siding is worth the investment because it returns more at resale and lasts far longer than vinyl.
Both materials resist rot and cut maintenance, yet they perform very differently in New England weather. Your budget, timeline, and resale goals decide which one fits best.
| Factor | James Hardie fiber cement | Vinyl | Better value |
|---|---|---|---|
| Resale return (ROI) | 144.9% | 97% | James Hardie |
| Estimated national cost | $21,500 installed | $18,000 installed | Vinyl |
| Durability | Thick, impact-resistant, storm-ready | Lighter, can crack in cold | James Hardie |
| Fire behavior | Fire-resistant | PVC, softens in heat | James Hardie |
| Upkeep | ColorPlus never needs repaint | Cleaning needed, can fade | James Hardie |
Top Recommendation: James Hardie fiber cement siding for the strongest resale return and longest lifespan. Schedule a free siding consultation to compare both on your home.
Best for tight budgets: Vinyl siding when lowest upfront cost and fast payback matter most.
Smart for resale: Fiber cement, since its 144.9% return outpaces nearly every exterior upgrade.

We serve 730+ towns across Massachusetts, New Hampshire, and Maine, with 7,000+ installations completed since 2011. On its own, James Hardie siding adds little insulation, but residing lets us air-seal and insulate your walls for real savings.
Fiber cement is prized for durability, not R-value, so the energy gains come from the work behind it. The air sealing and insulation done during a residing is what lowers your bills.
Top Recommendation: Pair James Hardie siding with air sealing and insulation for savings you can feel. Ask Coastal Windows & Exteriors for a full-envelope assessment.
Best for older homes: Add wall insulation during residing, since most homes lose heat through under-insulated walls.
Smart for comfort: A tighter envelope steadies room temperatures and eases the load on your HVAC.
Ready to lower your energy bills the right way? Coastal Windows & Exteriors evaluates your whole building envelope before installing James Hardie siding. Our Elite Preferred crew adds the air sealing and insulation that drive savings. A Service Excellence Award and 7,000+ installations back every project.

Carpenter ants and termites feast on wood siding while repainting every 3-5 years drains your time and wallet. Wood’s Class C fire rating means flames spread rapidly, giving families less escape time during emergencies.

Nashua earned its incorporation in 1853, though its industrial roots trace back decades earlier when textile mills transformed the Nashua River into economic power. The city’s iconic Main Street features stunning Victorian commercial architecture that survived the decline of manufacturing in the 1950s and 60s. Today’s Nashua blends historical preservation (like the Hunt Memorial Building downtown) with modern tech corridors that attract Boston commuters seeking affordable housing just 45 miles north.
Mine Falls Park provides 325 acres of trails winding through former mill canals, while neighborhoods like Crown Hill showcase turn-of-the-century Colonials alongside contemporary construction. The community thrives on cultural diversity—over 20% of residents speak languages other than English at home—creating vibrant international markets and restaurants that make Nashua feel cosmopolitan despite its 90,000 population. Housing styles range from compact Cape Cods near downtown to sprawling Colonials in suburban developments like Amherst Street corridor, all facing the same weather challenges that demand superior exterior protection.
As James Hardie Elite Preferred contractors, we follow best practice processes that separate professional results from amateur outcomes.
