Insulation of attic

Our salesman was exceptionally friendly and easy to deal with. The process went smoothly and we notice a big difference in the temperature of our upstairs. workers were very professional and did a great job cleaning up after themselves.

Garage insulation

We had Phil and Darrell to insulate our attached garage today and they were awesome! We were quoted a day and a half and they were done by 1pm! Our garage was already dry walled and painted so they had to drill small holes to add the insulation. They explained everything and advised us how to cover the holes back up. I would recommend

Great job. Worth every penny

Couldn't be happier about having this job done. The gang from GNI were very informative on what was involved and the improvement's going forward. Bring on the WINTER months.
Thank you GNI,

Home winterproofing

When I called to inquire about our house winterproofing I spoke with Randy and he answered all my questions right away and made my appointment for the following week. Branden and Tiffany arrived on the scheduled date and explained everything they were going to do. They started the work right away and when something came up that they were unsure of what we thought they asked us our opinion how we would like it done, very professional. When we asked any questions they were very knowledgeable with the answer. They were always very courteous and did their work with pride. We were very happy with the end results and would highly recommend Great North Insulation Company to do the job right.

New shop attic blown insulation.

I'm a repeat costumer. My house attic was topped up by GNI a few years back. The company/team members did a great job. I've decided to have my New Shop insulated by them.

Chris and Mark did a great job. They even took the time to cover up my classic JEEP.

Attic Insulation

A neighbour was getting attic insulation from GNI and I called the company to get a quote. We also had other companies give us quotes.
Mike dropped by a couple of days later and frankly was an amazing person to deal with. He was very polite, professional and pointed out things that the other companies did not.
We were also lucky because when setting up a date for the insulation they had some cancellations and were able to fit us in.
The two men who showed up were also very professional and polite. I'm sorry I don't remember their names. They put down drop sheets, kept things very clean and vacuumed up everything at the end.
All in all, we were very pleased and would definitely recommend GNI.

Drill and fill insulation

The company cancelled the scheduled appointment twice. Then, on the third time, they showed up but had not brought the drill heads. Finally, they did not finish the work and left the house with holes all over. They didn't show up the following day to finish the work. When I called to inquire , I was told that they can not schedule yet. We were left with mess and holes all over the house.

Afternoon Allan, Let me start off by sending you my sincere apologies for this. It doesn't sound like the workmanship that Great Northern Insulation is known for. I ask if you can email your address to Customerexperience@gni.ca We will look into this for you and try and resolve this matter ASAP. - The Customer Service Team

Insulated attic

The guys did a great job. They were curteous, and cleaned everything up very well when they were finished. Mark and Chris came, did their work, cleaned up and were very polite and helpful when we spoke.
My thanks again.
