Cullen Insulation is a local insulation installer, building science expert and energy performance consultant. We built our business on the simple, honest qualities that add up to total customer satisfaction. Cullen Insulation started in 1988 with $700 to buy a used pick-up truck. Through skillfulness, attention to detail, and pride in workmanship, we have expanded to four locations, more than 60 team members, and over 40 vehicles. Our offerings now include fiberglass insulation, spray foam, rigid foam insulation, waterproofing and air barrier installation—and we service both commercial and residential projects. With locations in Fargo-Moorhead, Grand Forks, Bismarck and Sioux Falls, we can be where you need when you need us.
Over the years, we’ve become known as a leader in our market, and we’ve received national recognition for our exceptional insulation practices by the Owens Corning® Certified Energy Expert® program. However, our growth has not shifted our foundation. First and foremost, we maintain a commitment to excellence and a pledge to do simply the best job on time, every time.
