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

Attic and wall insulation

Jason and his partner insulated my walls from the outside and attics, they continued to work even though it was getting dark and cold. They cleaned up very well and came in to let me know they were done, very polite guys

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.

Attic insulation

Outstanding service!. From the inquiry call, meeting with sale rep Bill, follow up emails from Aleshia, to the day of the install by Henry and Darrell, I have had nothing but courteous and professional service from GNI. The quote was exact, no hidden fees and any questions I had were promptly answered. The work was done in a timely and efficient manner and the guys cleaned up after themselves. I highly recommend GNI!!
