Dolphin Insulation

Dolphin Insulation is an insulation contractor that focuses on energy efficiency and comfort in homes. Its main work is blown-in cellulose insulation, air sealing, ice dam prevention, and improving indoor air quality, sound control and comfort in hot or humid homes. The company says it uses cellulose because it is made from recycled paper, resists mold and fire, and manages moisture well.

The company serves homeowners across Massachusetts, southern Vermont, New Hampshire and Maine, northern Rhode Island and Connecticut, and works on some commercial and historic buildings as well. Its office is in Littleton, Massachusetts, and it is a family-owned business operating since 2003.
