Great Northern Insulation

The sales rep. (Mike ) and all the staff were excellent. Work was completed ahead of schedule and their professionalism was a welcome change after dealing with other contractors. I would recommend them without any hesitation.

They came out the same day I called and gave a quote and they were the cheapest. On the day they came out I got more work then expected and didn't charge more for doing it.

I had a simple top up of attic insulation. The individual who gave me a quote was friendly, professional, and thorough. There was a little bit of a mess to clean up after he went up and took a look at the attic. So there were pieces of insulation on my son's floor afterwards. The work was booked and completed within a week since it was an easy job. On the day of the work, the labourers were also friendly and attempted to be considerate. They did arrive almost an hour early so I had JUST changed and got out of the shower. Although they covered my son's room with a sheet, insulation stuck on them so there was a trail of insulation from my sons room down the hall, the stairs and out the door. It was also a rainy day so insulation that was flying from their truck must have escaped the hose or the truck but the front of my garage door was COVERED in wet insulation. Due to the rain I couldn't clean it up until later, and it had dried and became difficult to clean up. My garage door is black so it was really noticeable. I let the company know but no offer of support for all the clean up I had to do after the work. The actual work was fine but the clean up after, didn't make me 100% happy.

Had basic 1970's insulation in attic and the boys showed up, on time and ready to work! They put all the attic vents in and answered all my questions. When they were finished I had R60 up there.
Second crew, had a little trouble making the window I was given, for them to arrive. But being in a service providing industry I get it when your new equipment isn't working right and need to get it replaced. But they did make it down to me! Thank god I couldn't take another Vacation day. These guys came in ready to work too. They covered all of my stuff to protect it and did a fantastic Job spraying everything I wanted.
Thanks Steve M

This was the fourth attic I have had insulated by Great Northern.
Always do a great quick job at a reasonable cost
I will continue to use and recommend Great northern to friends and family

Extremely pleased with the service from GNI from start to finish. Quote and appointment were easily set up with an explanation of scope of work required. Work completed as quoted with a great crew, Bob and Brennan doing a great job. They showed up on time, were very friendly and did a nice job covering up areas of my home that could get dirty and cleaned up. When they left you would never have known they were here.

Would highly recommend GNI and will use again.

GNI was great from start to finish. The in-home estimate from Bill was an educational experience. I contacted them about the attic insulation, but we went through the entire house to make sure any weak areas or cold spots could potentially be addressed. This knowledge also was clearly demonstrated when we discussed what the attic required. The timing of our discussion was when R50 was still considered code, but Bill was aware of upcoming changes to R60, so that was the option we pursued.

The two lads that came to do the work were on-time, courteous, and very careful with their work. They carefully wrapped our banister that their equipment would be resting on top of, covered all of the paths they would be using with drop sheets, and were very careful exiting the house after the job (while covered in insulation) to minimize any impact on the house or its occupants.

The changes in temperature stability were quickly noticeable and I'd highly recommend GNI to make sure your home is running the way it should be. Thanks GNI!

Everyone we dealt with was both knowledgeable and professional. They knew exactly what we needed and explained things really well. They even took the fact that we have an infant into consideration and scheduled the various aspects of the job so that it was done as quickly as possible in order for us to get back to normal routines within 24 hours. I would definitely recommend this company to family and friends!

Great job! really happy with work from start to finish. From the quote to the completion of the project. Very professional crew.
took the initiative while on the work site with recommendations as to how to improve the finish product at no additional cost to us

They were on time and when they showed up I was unaware that we had to be out of the house. These guys were amazing and even helped me to get my pets out as I just had surgery and was not able to do much. Great prices and great people!
