Great Northern Builders

Great Northern Builders is a woman-owned general contractor that handles home remodeling, additions, accessory dwelling units, kitchens, bathrooms, primary suites and whole-house renovations. The company designs projects that blend the character of older New England homes with modern building science, and it is known for organized planning and steady communication with clients and trade partners.

The firm works throughout the Seacoast of New Hampshire and southern Maine, and it will travel beyond its usual towns for larger projects. Homeowners start with a pre-construction process that lays out costs and timelines before work begins, and projects are tracked through a shared client portal. The company's address is in South Berwick, Maine, and it offers a warranty on completed work.
