I originally heard about Great northern Insulation from a friend who recommended your services.

I decided to contact GNI for our own basement and Bill Barlow came out to quote our space not long after. I was very pleased with the initial response and the quoted cost of the job was even better!

When we decided to book our date to have the work done, I was amazed how fast GNI was available to come out to complete the work. I had Bill stop by on Thursday afternoon for the quote and he said they guys could come as soon as the following day! I opted for the Monday appointment to allow my husband and I to prepare the basement for the crew to work comfortably.

When they crew arrived they attended right at the time they said they would. They were very polite and professional. We did a walk through of the basement and they answered all my questions without hesitation. They also asked if I would like a call when the job was completed and the house was locked up. Our entire basement took under 3 hours - just like the crew said and they followed up with a call letting me know the house was locked up and secure.

When I returned home the following day I expected some kind of smell but there was NOTHING! I had to go into the basement to make sure that they actually did the job! It looked great and I could immediately feel a difference down there.

Overall, from quote to completion I couldn't be happier. Great Northern Insulation definitely delivered and I will gladly recommend them to anyone looking to spray foam their home.

All went great, your crew was very nice to deal with, true professionals. Not one negative critique on performance.

A possible value add for you company. The spray foam has a strong odor to it. We set up fans on the basement windows to draw out the smell from the house creating a negative pressure in the basement. This left the entire house totally odor free.

We had our own fans but it might be a thought for you to have the same when working in occupied houses.

You could possibly charge for it or at lease recommend home owner/contractor provide in your documentation.

When my customers arrived home they were very please not to be able to smell a thing.

We will definitely use you again in the future if need be and will recommend your company to friends.

I am satisfied with the attic insulation work performed by Great Northern Insulation. Before estimate for the job was given, there was thorough examination of the attic condition to establish what needs to be done before blowing insulation. The staff during the estimation process and on the day the insulation was blown very courteous efficient and knowledgeable. I have already recommended your services to a neighbor.

Thanking you

The crew who came to do our insulation job were efficient, tidy and did an excellent job. We appreciated the fact that this job was taken care of expeditiously and in the same manner as had our previous insulation job in 2014. Should we require additional insulation, Great Northern is at the top of our go to list.

My experience with great northern insulation was great. I would definitely use your services again and recommend GNI.

The sales representative, Aaron, was friendly, knowledgeable, and answered my many questions by email. After the instillation he came by to inspect the work and see if I had any concerns.

The installers were very professional as arrived on time, answered my questions and did a good job cleaning up .

Finally, scheduling was very easy and flexible. I had to reschedule once as I was not ready for the insulation and rescheduling was no problem..

Thanks,

everything was great. Your installers were terrific. They were early, which was good as I was not late for work and went over everything with me and were in the process of covering everything in plastic when I left. I look forward to working with your company again when I insulate the other half of my upstairs. Thank you
