Garage insulation

My experience with Great Northern Insulation has been has been second to none. Alana the sales consultant that came to assess the job and give me a quote was very punctual, professional and personable. Alana provided me with a very reasonable quote in a very timely manner. Paul and Shay, the insulation technicians arrived on time in a very clean vehicle and presented themselves in a very professional manner. They started work immediately with no disruption to my day and did their work in a very timely and professional manner. Their attention to detail in their work and the clean up of the job site left me very impressed. My experience with Great Northern Insulation and specifically Alana, Paul and Shay has been amazing. I would not hesitate to recommend Great Northern Insulation to anyone that needed an insulating job done. Thank you all for your amazing service, it has been a pleasure to work with you and support your company.

upgrading insulation & draft stopping

Derek and John showed up on time. They were courteous, efficient, and left a very small amount of clean-up. John was very friendly and complimented me on my home, saying it was nice.

removing insulation from attic of old home

The work done was excellent. All the insulation was removed and made my renovations a lot easier. It is an old home and the job to move around in the attic would have been very difficult, but he did it. I would reccomend Great Northern Insulation to anyone else that asks. Thanks.

new home construction

My husband and I were building a new home and called Great Northern for a quote. They were prompt to get back to us with the estimate. Although they were not the cheapest when we called them back to tell them what other prices we received they matched it no question ask and were at our house the following week to do the job. I would recommend them again in a minute.

new furnace installed

The men worked quick and adequate. Awesome service. Will recommend to others.
They came sooner than originally planned as well. They said having no heat is a priority with them.
Thanks Chris and Andrew
