Attic Insulation

We've recently had our attic insulated through GNI and are very impressed with the overall quality of service and product. Peter has been exceptional at answering all of the many questions we had about insulation and GNI's product. The young men that came to do the work were very professional. I highly recommend GNI!

Insulation

They are very thorough. They did not leave a mess. They did a bit more than was required. Peter Brenner was friendly and knowledgable and only focused on what had to be done. The workers that actually did the job was also good.

insulation on 8 year old home

i had a gentlemen called Peter visit. He went up into the attic and was able to show me the problems with heat and cold in the bedrooms.Took pictures then came out and insulated the attic. They took pictures after to show the work as well. These folks were on time,through and very clean. Very impressed. I have sent them to my sisters and they resolved her ice problems. For 5 years she has had problems,this winter none.
I give these guys 7 out of 5

Attic Insulation Upgrade to R-52

It is hard to find good insulation companies, but after lots of research I finally found the best in GNI. Tremendous value and professional and courteous service with our attic insulation upgrade to R-52.
They also weatherstripped and cribbed the hatch access door, foam air-sealed the ceiling fixtures and plumbing stack, installed 4 styrovents, installed fibreglass to clog the fireplace flue and did a great job with the blown-in cellulose.
This was a great choice for attic insulation and I have felt the benefits this winter with much warmer house and gas bills cut significantly!

Attic Insulation

I contracted Great Northern to insulate my attic from an R22 to R50. I had three other companies quote me. Prices range was much higher with al of the additional costs for new vents. Great northern price was 25% lower and they told me that there was no need to change vents nor any repairs was necessary. Thier price was exactly as my own calculations....I am an Engineer. Their guys were professional, courteous and considerate. Unknown to the guy in the attic, I was behind him looking at the job he was doing, Checking the height and layer of the job and was pleased to see it was being done to my expectations. I could not find anything to complain about even though I was looking for a flaw. Great job, I would recommend this company.

Garage insulation

Friends had their garage with a bedroom above insulated and the diff. in heat retention in the winter is amazing. This is a good investment to save on your heating bills. Cost varies depending on size of area but will pay for itself in a short time and provide comfort.

2nd floor addition

We put on a new 2nd floor and had Great Northern install the insulation. We found them helpful and very reasonably priced. Stuart was responsive and the installers were friendly. I would use them again if I had the need.

Foam insulation in basement and around skylight

Just moved into a new house and the skylight tunnel needed some insulation around it and so Great Northern went up and tried their best not to disturb the existing blown in insulation and put it back in place when they were done. They also put foam insulation into a room in the basement that I will use for storage - it was the only room with exposed walls in the basement. Am considering having them back to top-up my existing insulation in the walls.

drill and fill insulation

On the surface this company might appear to be professional but nothing could be further from the truth. This is a disorganized group of people that cost us over $200 due to their incompetence - 15 holes were drilled into our walls for nothing.

When given every chance to make it right we were ignored. When our issue was taken to the President, Steve Resser, our frustrating experience was treated with indifference and contempt. It became clear as to why we were originally ignored - the company's attitude stems from the President. Use this company at your at peril.

Company Response

Retrofitting existing home walls can be fraught with challenges. There is an element of guesswork as to the exact construction of the existing walls, even if the walls are explored with drilling small holes at the time of investigation by a technical/sales representative. This invasive approach to determine if the walls are suitable for retrofit is not perfect, and in this case all of the walls considered for retrofit by the customer proved to have insulation within the wall cavities.

Typically our field technicians will drill a hole, and probe the wall cavity to determine the wall framing pattern. In this case, they found insulation, advised the customer of same and our crew was then directed by the customer to continue to drill exploratory holes into the walls considered for retrofitting. Our company does not patch/finish holes…something that is not practical to complete in a ‘days’ installation (compound will not dry), as such there is always a responsibility by the customer to patch and finish these holes. This is always explained to our customers at the time a sales agreement is reached.

Unfortunately when a project does not work out to everyone’s expectations there are hard feelings. We are of course upset that we could not complete the work, even more so that we could not reach an amicable resolution to this situation. Great Northern remains committed to supplying quality products and services and with anything in life, we take away lessons learned from every experience with our customers.
