The install went well, the guys were good. Did find two leaks, and a gash in my dryer vent pipe, nothing worth sending anyone back to fix.

I will be calling you guys again once I'm in a position to rip out some walls in the basement - probably by the fall of 2016.

We were referred to Great Northern by an individual who was helping us address our heating and ventilation concerns. The team at Great Northern was very organized and professional and the work was completed in a timely manner. We would not hesitate to refer Great Northern to our friends and neighbours.

Thanks again for addressing our needs so quickly,

It was all good. The sales rep was very knowledgeable and helpful. Your install crew were super. I have recommended your company to others. Only down side is the long wait list for install. I'm still waiting on a install for work with your company.

I want to say I was really happy with the service that was provided. The installers were really friendly and explained what they were doing. They were there early in the morning to start the job. I highly recommend them

I am quite satisfied with the work performed by Great Northern.

Sale Representative
He was knowledgable and answered all my questions. He was also willing to negotiate the price as I wanted the BASF product.

Site Pre Inspection

He was polite and efficient but should have advised that the tar paper needed to be removed for proper bonding and sealing. I only found this out when the installers came out. Needless to say I was not to impressed and probably shot the messenger.

Installers

All three of them were very good and answered all my questions. Again they let me express my displeasure with the pre site inspector failing to notify of the proper sealing and bonding with the removal of the tar paper and I probably took it out on them. This would have been completed prior to the installers. They listened and each of them gave me assistance removing the tar paper. They were professional and worked with a customer that was having a bad day but definitely got better with them assisting. They worked efficiently and seemed to work well together. They cleaned up after themselves and removed all garbage with them.

In summary I am satisfied with the product and the installation. I know I will be calling you again on the next project.

We are satisfied with the service we received. The sales rep (Davis) and schedulers (I am sorry, I don’t recall their names) were great.

The installers were a little late starting at our neighbours, and therefore they were late starting at our house, for which they did apologize. Once they got started, they were polite, courteous, professional, fast and they left the house tidy.

It’s hard to comment on our satisfaction with the work because it’s insulation and in our attic. We can’t see it and won’t know if its made a difference until we get through a winter, and get ceilings upstairs repainted and the discolouration doesn’t appear again. That being said, we have faith it was done properly but will follow up is we do have any concerns.

The installers were prompt,courteous and efficient. They did an excellent job. What I liked was the initial meeting with Aaron. He took the time to explain and show exactly what needed to be done. The price was fair for the work that was done.
