When I call for a quote from Great Northern Insulation they returned my call the next day. A day later Mike came out to see the home gave me a quote. I scheduled the job. On the day the work was to be done the guys were here on time. They were friendly, polite and professional. Before leaving my home they cleaned up not only in the house but my driveway as well. GREAT JOB GUYS. I certainly will recommend Great Northern Insulation to all my family and friends.
