Based in Haverhill since 1973, Coastal Industries was founded by William J. Cunningham Sr., who brought his experience from General Aluminum to launch a family-owned business focused on storm windows and doors. Over the years, the company evolved to include vinyl and aluminum products, maintaining traditional craftsmanship while embracing modern manufacturing advancements. The business became a true family enterprise when Bill’s son Blaise and daughter-in-law Linda joined in the 1970s. Today, Coastal Industries continues to manufacture storm windows, deadlites, and picture windows using the same methods developed over 50 years ago, while also producing energy-efficient vinyl and aluminum windows with advanced welding and corner cleaning techniques. The company partners with trusted manufacturers to offer specialty designs, including arch-top operable windows and custom entrance doors.
