We want to let you know we were very impressed with Great Northern Insulation's customer service and promptness in responding to our questions! Given the nature of our project (an old cottage renovation), there were a number of very challenging issues, for example, the treatment of the area where the old cottage roof met the new addition's roof.

Sean and his team were patient, thorough, and very professional in conducting the work.

The project required more time then originally contemplated and the Northern team was very responsive in finding additional time for the team to finish the work promptly.

On our return when the work was completed, the cottage was spotless, not a drop of insulation on furniture or flooring. We had also forgotten when they began the work to have them cover the main exposed beam and they had already proceeded to begin to spray. They promptly cover the beam at our request. But when cleaning up they had actually gone back and cleaned the beam up...Unexpected! Bravo and thank you!

A great experience and our thanks to the Northern team!!

Insulating our attic as best as possible according to how our house is structured

We called 2 previous companies and great northern insulation were the only ones to take on our project. It wasn't too small for them. They came on the day they said they would and left the house in a clean state. Wouldn't hesitate to recommend to our friends.

I believe your crew and firm deserve a "Job Well Done" for the basement work completed on Oct. 6, 2015. Kevin and Kevin make a great team. I felt completely at ease leaving the home in their care. The work done was clean and precise. All I have to do now is add drywall. We are exceptionally pleased and will mention our experience to others.

A few years ago, we had an entire house spray foam insulated by GNI as we completely renovated an old farm house. The very low Natural Gas heating bill for this home was astonishing. Because of this, we recently had GNI spray foam our basement rec-room. Beautiful job showing careful craftsmanship in applying the product. Even my dry-waller commented on what a great job GNI had done. Thanks again.

Home Insulation

Our family was part of the Union Gas Home Weatherization Program. Scott and Jeff were the gentlemen that installed our insulation. They showed up on time, introduced themselves, and made us aware of the amount of time they would be there each day. Every day they were here they made sure the items in my home were covered, and they vacuumed before they left.
Both of them were very informative regarding the products that they were using, and the way that the products will insulate my home. While they were working, they never made it so I couldn't be in my home. They were here for three days, as my whole house needed insulating, and at the end, my house was a clean as it was before they started. Good, professional, and nice guys to boot. Will recommend to others:)

The sales person (Alana) was very helpful. Our experience with the crew was excellent. They were very polite and attentive to detail. They kept our house as clean as they could considering their task. If I were to have one negative comment it had to do with the scheduling. We were advised two weeks in advance the crew would arrive in the AM of the 24th between 8:00 AM and 9:30 AM. That time passed without phone call. I followed up with your office in Milton and was told that I would receive a return phone within 1 hour. That time came and went. We were now worried that the entire job was not going to happen. We called again and this time it was confirmed the crew would come in the PM. Suggestion: Give a pre date confirmation of the job. The times could be reconfirmed and it would also alleviate any confusion on the part of the customer.

We are enjoying the comfort of the new attic insulation.

All staff involved were excellent! We first dealt with Ian who provided a quote back in May and responded back quickly when we had to modify the quote slightly. He was very courteous, professional, thorough and actually crawled in the tight attic in order to visually see what insulation was required.

Kelly and Mandy scheduling the work were very pleasant and accommodating.

Installation went great!. Truck showed up first thing in the morning. The two young guys were pleasant, organized, tidy and did a great job. I was pleased with the job overall.
