James Hardie fiber cement siding combines cement fibers, sand, and cellulose fibers into a composite that outperforms wood and vinyl. The cement fibers create structural strength that wood and vinyl can’t touch. Sand adds density and weather resistance protecting against moisture. Cellulose fibers bind everything together while allowing natural expansion and contraction. This composite mimics wood’s look without inviting rot or pest damage. Dunbarton homeowners trust this material because it stands strong when cheaper products fail season after season.

James Hardie measures five times thicker than standard vinyl, giving you way better impact resistance. Wood siding invites carpenter ants and termites while rotting from moisture—Hardie never rots. Vinyl cracks in freezing temps and melts when summer heat reflects off windows. James Hardie earns a Class A fire rating that slows flame spread, while vinyl melts and releases toxic fumes (though fire-resistant means slowing spread, not stopping it—there’s a big difference). Wood needs repainting every three to five years but Hardie’s ColorPlus finish lasts decades. Hardie’s rigid foam insulation options dramatically improve energy efficiency compared to hollow vinyl. The performance gap isn’t even close.

James Hardie’s Class A fire-resistant rating slows flame spread, buying critical evacuation time (remember, fire-resistant means slowing spread, not stopping it completely—that’s an important distinction). This protection proves invaluable for Dunbarton homes near wooded areas where fire risk increases. Vinyl siding melts fast and releases toxic fumes poisoning the air your family breathes during emergencies. Fiber cement doesn’t feed flames or contribute accelerants when fire strikes. Peace of mind comes from knowing your exterior walls won’t betray you when seconds count most.

Dunbarton got incorporated in 1765 after being called Gorham’s-town back in 1735 and then Starkstown in 1748. The name comes from Dunbartonshire, Scotland—that’s where prominent settler Archibald Stark was from. His son was General John Stark, the “Hero of Bennington” during the Revolutionary War, and his grandson Caleb started the textile mills that made Manchester an industrial powerhouse. The beautifully restored First Congregational Church from 1836 sits on Dunbarton Center’s western common, and its steeple was designed to look like Boston’s North Church.
The Town Hall from 1908 stands where the original 1789 meetinghouse used to be before it burned down. There’s a bronze statue of Caleb Stark commemorating his service at Bunker Hill with his dad. Here’s something cool—a Boston University geography professor calculated in 2008 that Dunbarton is actually at New England’s true geographic center! You’re about 10 miles south of Concord, 13 miles north of Manchester, and roughly 60 miles from Boston. Dunbarton stays a quiet bedroom community of around 3,000 people who love the spacious five-acre lots, gentleman’s farms, sugar shacks, and rural feel. You’ll find everything from historic 1810 Colonials and Cape Cods to modern farmhouses and custom builds with forest views, and folks here keep that small-town New Hampshire character alive.
