Insulation

We decided to upgrade the existing insulation in our home. From quotation to completion of the installation I was kept informed and updated as needed. I was very happy with the quotation cost. The installation team were meticulous, tidy, provided protection where needed and cleaned up upon completion. I am very happy with the service. I would be happy to be contacted by potential customers to confirm my recommendation of this company.

Attic Insulation

Team of 2 came in, took over, prepared the areas, did the work, cleaned up, explained a few things and left. Completely unobtrusive, professional, quick and to the point. Loved it, since my days are usually very busy. This was a no muss, no fuss, great job.

Attic Insulation

The two reps (Henry and Matt) arrived on time and were appropriately suited up and had masks and gloves on. They were professional and went right to work, explained what they were doing and were good at cleaning up afterwards.

Garage Insulation

We had a garage that was so cold in the winter that it was affecting other parts of the house. We ordered for home insulation services with gni to remedy that. Paul and Jeff came onsite and were an excellent crew. They went through the process and clarified our order, working quickly and diligently. The garage is warmer already.

Attic insulation

Joel and Gabe arrived a bit early to insulate our attic. They put down plastic and removed their boots, were pleasant, worked quickly and cleaned up after themselves. I would recommend them for a job well done with minimum interruption to your household.

Insulation top-up

My daughter knew I was considering getting more insulation, and recommended GNI to me as she was very happy with the work they did for her. Rob came out and did the estimate. He was pleasant and professional; a very good first impression for the company. When the guys came out to do the work they were on time, efficient and again, very professional. They also did a great job on clean-up. I'd hire this company again anytime.

Great Company and installers !!

I submitted a request for a quote and Angelo got right back to me. The quoting system is very slick and easy to use !!

This morning I had my attic topped up. Brian and Rob were great !! They were perfectly on time and very courteous. They used drop sheets and cardboard on corners so the hose would not scratch anything. They also cleaned up when they were done... Give these guys a raise, they deserve it.

I highly recommend GNI...

Attic Insulation

Sean, Bill and Phil were very professional and efficient. They worked quickly to get the job done, with minimal disruption to my daily routine. They arrived on time as scheduled, and immediately identified themselves. Provided an explanation of what would be done. Cleaned up afterwards, leaving no trace that they were even here.
