Great Northern Insulation

GNI was very professional, staff Brennan, John and James were on time, very friendly, covered all of the area into house with drop sheets, and left the house clean.

Very professional, friendly staff and always on schedule.

This is the second time that I have used GNI. Once on my own home, basement spray foam and headers, and once last week in my Mothers home, basement spray foam and headers. Both times, Great Northern was on time, did a great job covering up the flowers and windows, competed the job as per our agreement. Would highly recommend working with them.

Salesman was excellent - knowledgeable, friendly , punctual , job was done on time and very weel done - some small areas missed but overall very pleased , price was good also

Great crew of guys, Brennan, Lucas and Colton. They arrived on time and began by laying down drop cloths and providing cardboard protection to potential hose rub points on furniture and doorways. They worked efficiently and quickly, and cleaned up after themselves. Because our insulation was a different product than what they had blown on a previous job, they cleaned out the hopper before beginning. They really do care about providing the best result. We would absolutely recommend GNI. Great job
