    I highly recommend Great Northern Insulation. They did a great job installing foam insulation at a reasonable price. We received a quote from another contractor that was much higher. The salesman/estimator (Eric) was very knowledgeable and helpful in ensuring that we understood the process and selected the right product. I would hire them again.

    had your company come in to spray foam and blow in attic insulation to a new garage which we just build. Your staff were there on time, pleasant, courteous and new what they were doing. Asked me to look over everything before they left, both levels were cleaned up and all garbage was removed. Would definitely recommend Great job
