Great Northern Insulation

Had my basement spray foamed about 5 years ago by GNI. This time it was for an attic top up. Matt, Gracie and Santagio were very professional and did a great job. Left the place spotless and warmer. All around positive experience from the first contact with the rep Alex to the final top up.

Very prompt and thorough. Cleaned up extremely well and assisted elderly neighbour struggling outside. Great job! Thank you Gracie and Kyle!

Gracie and Kyle were very professional and did an amazing job doing insulation for my attic. Everything was seamless and easy, definitely recommend!

Today we had two amazing young men insulate our attic. From the moment Gurvir and Jermaine arrived they were courteous and listened to us as we shared what some of the issues were in our attic that needed extra care.
They were meticulous in the preliminary care of the room with the attic entry point. They spread plastic sheeting over the furniture and the walls to protect the room from any possible insulation leakage.
They took their time in the prep work prior to putting the insulation in. They made sure bathroom exhaust fans were properly sealed in the attic. They put in new baffles to provide excellent ventilation and made sure that the attic was ready to receive the new insulation.
They did a beautiful job of putting in the insulation to the height necessary for R60. My wife and I were delighted with the outstanding work that Gurvir and Jermaine did in our attic and will heartily recommend Great Northern Insulation to our friends and neighbours! These men are a credit to your company! Thank you for sending them to do the work in our home. We are very pleased! Jim and Joy Danielson

Very happy with service from end to end. Gast response to my quote request, thorough estimate, clear advice and extremely competative price. They scheduled the work around my schedule, were clear on the dates, showed up on time, worked carefully and cleanly, and finished in the time predicted. The removal crew worked hard to get the old damaged insulation out of the attic and left the house and yard spotless. Same thing for the installers for the new installation, Gurvir and Jermaine. Worked fast, left the house and yard cleaned, and explained very clearly what they were doing and why.

We had some insulation installed in our home through the winter proofing program. The whole process was quick and the technicians were very friendly and easy to work with. They cleaned up at the end of each day and made sure to plastic over all of our stuff. The house already feels warmer!

Thanks to Tom and Jerrod for a superb job on installing insulation in a section of our basement. The work was high quality and completed on schedule. We would highly recommend this team and company to meet your insulation needs if you are seeking full satisfaction. Excellent job! Merci beaucoup. Jacques and Sharon Carrier

Excellent Value and very professional service. Jermaine and Gurvir did our attic insulation. Excellent communication and very respectful of our house and furniture during the entire process. Thanks to all at GNI. Curt

Our installers Gracie and Matt were amazing to work with. They took great care in the preparation process and were sure to cover all of our belongings before starting the instal. They also took lots of pictures for us before and after completing the job. And they’re just lovely people! In our experience a lot of tradespeople are grumpy when it comes to doing jobs in downtown Toronto; there are always parking challenges, for example, and we often hear ‘why would you want to live here, you should just move to blah blah instead! ’ Matt and Gracie were wonderfully positive from start to finish. Highly recommend!

Gracie and Kyle installed R60 cellulose for our attic, they did a great job would highly recommend. Professional and prompt.

We had GNI top up our blown fiberglass in the attic. Our Installers Jermaine and Gurvir did an excellent job. The house is fully carpeted and I was impressed that they did not have to be asked to remove their shoes. The carpet in our room was covered and the closet area was sealed to minimize dust. They cleaned up when the jobs was completed.
All of our questions were answered and they did not hesitate to take pictures for me.
UPDATE: yes we've notice a big difference in the upstairs rooms. It is no longer the coldest place in the house. Thanks again GNI

Fast, efficient and friendly. Left the house in better shape than when they arrived. Props to Jermaine and Gurvir.

The team - Gracie, Harpreet, and Kyle - did a fantastic job from start to finish. It was a big attic job. They were careful to sheet everywhere, left it as clean as possible, did a thorough job. They were also very courteous as it was a whole-day job and I was conducting online meetings. Very professional, highly recommend

Jermaine and Gurvir were very professional and left my home clean after they finished blowing in the insulation

Great working with Jermaine and Gurvir from Great Northern Insulation. Friendly and very knowledgeable. They taped everything off prior, and left everything the way it was before they arrived. Highly recommended!

Great crew, worked as long as it took to complete the job. Thanks to Gracie, Kyle and Jason

Harpreet and Kyle did an amazing job insulating my attic. They were extremely polite and respectful.
They worked efficiently and took the necessary time setting up to protect my newly renovated home from damage (plastic drops on walls and floor and cardboard protection on all corners where hose was run) and cleaning up when they were finished. You would not know they were here except for the 18” of insulation in my attic.
Great experience.

Fantastic attic insulation top-up by Jermaine and Gurvir. They did a great job and they answered all my questions. I definitely recommend them! 0

I really appreciate Germaine and Gurvir’ work. Their work is so professional and they are so helpful and cooperative. I recommend them to everyone who needs insulation for their Attic. They covered everything before work, they also cleaned the floor and left the house clean as it was before the insulation. Thank you very much Germaine and Guvir.

Jermaine and Gurvir. Excellent job. You explained everything and completed the work quickly and neatly. Thank you

Gracie and Harpreet were quick, clean, friendly, and accommodated my difficult situation! Thank you so much!

We had GNI come to do an attic insulation & spray insulation in our basement. Sarah and her team did a thorough and fantastic job. Extremely friendly and professional team. High recommend GNI for insulation.
