It all started by meeting James and Jason to acquire a quote to get the 60 years old attic insulation removed and proceed with a re-insulating our attic. Great Northern Insulation had a very competitive price, not the cheapest but the company, due to their representatives, was by far the one that inspired trust and good results. From the appraiser, the removal crew, the foam spray crew and the cellulose spray crew, everything went as planned. they showed up the day and at the time they said they would. That alone was bonus for me. They respect other people's time table. I am super happy with every steps, they left a certificate in our attic detailing exactly what and how it was done. Now I now that our home is ready for winter and that the job was done professionally. Thank GNI, I have no problem referring you to all.
