About Merrimack, NH

Windows in Merrimack, NH

Stretched along the Merrimack River between Nashua and Manchester, Merrimack is a spread-out, family-oriented town of wooded lots and the historic villages of Reeds Ferry and Thornton’s Ferry, with landmarks like the Anheuser-Busch brewery nearby.

Old, drafty and single-pane windows quietly drive up heating bills through long New Hampshire winters, so energy-efficient replacement windows pay homeowners back in comfort and lower bills every cold season.

Merrimack’s tree-shaded properties drop a heavy load of leaves and needles every fall, so clogged gutters, moss on north-facing roofs and proper drainage are recurring concerns — gutter guards are popular here for good reason.
