Milford separated from neighboring Amherst and became its own town back in 1794. The name comes from the mill built at the ford crossing the Souhegan River—a practical label for a practical community. Granite quarries once dotted the landscape, earning Milford the nickname “The Granite Town in the Granite State.” Those quarries produced stone used in landmarks including pillars for the U.S. Treasury building. Union Square—shaped more like a triangle despite its name—serves as the town center with the Pillsbury Bandstand at its heart. The Souhegan River provides a scenic backdrop where residents gather for the annual Pumpkin Festival each October. Milford also holds a place on the Black Heritage Trail of New Hampshire, having served as a stop on the Underground Railroad.
Located roughly 46 miles northwest of Boston and just 11 miles from Nashua, the town blends small-town charm with convenient access to urban amenities. Housing styles range from historic colonials near the Oval to newer developments spreading toward surrounding communities. Over 16,000 residents call Milford home today, supporting local businesses, schools, and a tight-knit community spirit.
Proper preparation prevents problems—and our installation process reflects that philosophy.
