Attic insulation project

If you want to redeem your faith in great and courteous companies.. this is the one..!!

Not only were Derek and Drew 2 of the nicest workman, they take extreme pride in doing things the right way. From start to finish they were courteous, polite, tidy and ensured everything was to our satisfaction.

I recommend this entire team from Lindsay to Angelo,
to Nick, to Derek and Drew we recommend them ALL 100%.

Thank you for a job well done !!

Excellent insulation up-grade

I asked our local contractor about an insulation/ventilation concern in our home. He had a look and advised me to call GNI as in his words, "they are excellent, professional and really know their stuff". So right he was. From very good conversations with the GNI reps in Barrie about what they felt I should and shouldn't do ( yes they actually talked me out of spending money on processes that would not have improved anything ) they came up with an excellent quote. The work was done within a week by a great 2 person crew. Super efficient, they explained the process, and with the aid of drop sheets and personal consideration, once they had finished, you would almost never known they had been here. Basically zero mess.
The entire GNI experience was First Class and would not hesitate to recommend them.

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.

Insolation

We had our bibs system installed in our new cottage. We also had our ceiling insolation as well as spray foam in the rims. Very impressed with the work done.

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.
